Advantages and disadvantages of a homemade stove for the garage made from disks. Do-it-yourself potbelly stove made from wheel rims

Did you redo everything at home while in self-isolation? It's time to go to the garage and clean it up! And at the same time, complete the repairs, organize storage areas, think about how to prepare the car for the summer, and the garage itself for the next cold season. And we continue to publish materials with the hashtag #BetteratHome. A potbelly stove made from old disks for the garage is an excellent option for organizing garage heating without extra expenses. The main thing is that you have welding skills. We'll tell you how to make such a stove with your own hands - now is the time to pay attention not only to household chores, but also to prepare your garage for the next cold season.

What is good about a stove made from rims?

A stove made of wheels is capable of heating a room measuring 15-17 m2. It is used, despite the specifics of the selected materials, not only in the garage, but also to provide heat in other utility rooms and baths. The main advantage of the heating device is the availability and high quality of the material.

The discs are made of durable and thick steel, which ensures long service life. The quality of the wheels is in no way inferior to boiler steel in sheets and profiles.

In addition, a garage oven practically does not dry out the air, and metal does not emit harmful fumes at high temperatures. The environmental friendliness of the material is due to the fact that the discs are made of specialized steel that is resistant to corrosion.

Process of creation

Constructing a furnace device from disks with your own hands begins with converting the disks into the necessary structural parts.

Such metamorphoses begin with a disk, which will be the upper compartment of the furnace being manufactured

It is positioned so that the fastening part is at the top. Next, a circular hole is cut using a grinder along the mounting holes and the cut out contents are removed. The dimensions of the circle are determined in relation to the existing cauldron, which will make it possible to achieve the stability of this specific dish. The hole must certainly be perfectly round, and therefore all flaws are corrected immediately.

The disk for the lower compartment of the furnace device is installed with the mounting platform facing down. Then the top one is placed on it, and their mating edges are carefully welded in a circle.

The result should be a welded structural blank

Let's move on to the combustion chamber system. To create it, a rectangular fragment is cut out at the base. Its approximate dimensions in centimeters are ~ 20x12 (for rims from passenger cars). When marking the location of the combustion chamber, it is necessary to make an indent of ~ 2 cm from the lower edge of the disk. Such a trick is guaranteed to provide not only high structural rigidity, but also facilitates the operation of the firebox.

The disk fragment cut out for the combustion chamber is preserved. In the future, it will serve as an excellent firebox door.

After completing the operation of forming the combustion chamber, you can choose two options for the stove under the cauldron from disks. One of them is extremely simple, but the second will require some additional steps.

Advantages and disadvantages

To heat the garage, the stove is made from Kamaz wheels - they are large in diameter

Before making a decision in favor of making a potbelly stove from disks with your own hands, you should objectively evaluate the positive and negative aspects of this structure.

Advantages:

Low cost. Minor investments are required, since the main part is made from waste raw materials or inexpensively purchased material.
Durability. In the production of wheels, special steel is used that is resistant to corrosion, friction and heating to extremely high temperatures.
Compact and lightweight. The finished product can be easily moved around the premises, and, if necessary, taken to other sites, including on hikes.
Easy to assemble. Even a novice repairman can make a stove from disks using a standard set of tools found in any garage.
Heating efficiency. The heater quickly begins to produce intense heat, creating a warm and comfortable environment in a matter of minutes.

Metal cools quickly after heating

Flaws:

Weak traction. It is necessary to significantly increase the height of the pipe, which means additional difficulties and costs.
Rapid cooling after fuel burnout. The walls of the fireplace are thin; it heats the building only if it is constantly loaded with fuel.
Intense heat from the walls. If you are careless, you can burn your hand.
Low height of housing and loading opening. It is inconvenient to heat the fireplace, as well as to cook using the top surface for cooking.

Based on an analysis of the features of the device, the prospects for its use and one’s own skills, a decision is made on the feasibility of its manufacture.

Types of potbelly stoves

To make a potbelly stove, a material with heat-resistant properties is required. These include steel and cast iron. Cast iron structures have a longer service life, since the characteristics of the alloy allow them to work at high temperatures without deformation and rapid wear. When creating a thick-walled cast iron body, it becomes possible to retain heat for quite a long time.

In addition to primitive designs, there are a number of devices that differ in their functionality:

Equipped with a hob designed for cooking food and heating water. The design does not exclude the possibility of installing an oven.
Devices equipped with a casing located along the body area. It is made of metal or ceramics. This design features improved heat transfer. This becomes possible due to the absorption of heated air into the space of the casing, while it heats up and evenly transfers thermal energy into the heated room.
Potbelly stoves of gas generator type. They have two chambers in which combustion occurs. The lower one is intended for fuel gasification, and the upper one is for afterburning gaseous substances.
Small-sized devices. As a rule, such stoves are used as an emergency heat source.

How to make a stove for a cauldron with your own hands from car rims - Home

Many craftsmen today make wood-burning stoves and boilers using thick-walled pipes. But sometimes such products become too expensive, while several old car discs may be on hand.

In this case, you can make a stove, which will be completely free. You just have to work hard on the design itself, using your own skill and ingenuity. Some masters even create “works of art” that deserve attention.

Such designs are attractive not only because of their performance, but also because of the thickness of the metal. It won't take long for the body to burn out, especially if you use a wheel from a truck.

The latter are used for the manufacture of sauna stoves, as they differ in overall dimensions and impressive metal thickness. For a sauna stove, which quite often operates under heavy loads, this factor cannot be called unimportant.

If you use the wheels of a commercial or passenger car, you can make a wood-burning heater for a garage or a small barbecue oven.

Preparing tools

If you decide to make a hearth for a cauldron or a regular stove using car wheels, then you need to take care of the availability of tools, among them the following should be highlighted:

welding machine;
electric drill;
chisel;
sledgehammer;
disks;
paint brush;
ruler;
grinder;
hacksaw for metal;
hammer;
file;
pliers;
roulette

It is noteworthy that almost any of the disk-based models made will be portable, which is very convenient, because this design can be used in a bathhouse or on the street.

It is best to use stamped steel discs, the diameter of which varies from 40 to 50 cm. Their height can be 25 cm.

The hearth for a cauldron, like a sauna stove, cannot be made of aluminum disks, or those made from aluminum alloys.

What do you need to prepare?

From the tools you need to collect:

welding machine (200A);
grinder – “grinder”, preferably with discs with a diameter of at least 180 mm;
electrodes;
circles for grinding and cutting metal;
hammer cleaning slag from welding;
a brush with metal bristles;
folding meter, tape measure, chalk or marker for marking;
drill and drill bits of the required diameters;
chisel, regular hammer and pliers.

From materials, in addition to one or two gas cylinders, you must purchase:

a sheet of metal, at least three millimeters thick - it is useful for constructing a hob and ash pan;
ready-made cast iron doors, or you can also make them yourself from a metal sheet or a piece of metal cut from a cylinder;
chimney pipe;
corner or thick reinforcement - they will be needed for the manufacture of legs and grate. The latter can be purchased ready-made (from cast iron) or constructed using holes drilled in the bottom of the cylinder.

It should be noted here that both a standard gas cylinder and a small cylinder are suitable for the manufacture of such a stove.

As mentioned above, a cylinder stove can be vertical or horizontal. You can choose the one you need based on the amount of space allocated for installing the potbelly stove and the ease of its operation.

Preparing the balloon

Proper preparation of the cylinder is a very important step before starting work, especially if the potbelly stove is made from a container that recently contained gas. Residual gas may remain inside, and when cutting, which is accompanied by sparks, the cylinder may explode

Therefore, you first need to unscrew the valve located on top of the cylinder and clear the passage for the remaining gas to escape - this procedure will take some time. It is better to leave the container open overnight in the open air or in a well-ventilated non-residential area, or even better - fill it with water to the very top.
Next, the container is turned over and the resulting condensate is drained. It has a very unpleasant odor, so this process should also not be carried out in a room where people live.

The washed container no longer poses any risk of explosion when working with it, and you can safely begin the cutting process.

Why are car wheels suitable?

When planning to heat a garage unit, its owner often has to solve the problem of saving money. Factory products are too expensive, sheet steel is also not affordable. In such cases, the optimal solution is old wheels from trucks of the ZIL, KAMAZ and GAZ brands.

The advantages of this material:

wide selection, including rims of the same size;
the opportunity to purchase blanks for free or cheap at the price of scrap metal;
use in the production of high-quality metal, characterized by strength and resistance to strong heat;
The initially round shape ensures the tightness of the assembly and heat distribution.

An important factor in favor of this solution is the thickness of the disk walls. They are strong, resistant to burning and conduct heat well.

What is needed to make a potbelly stove?

So, the most important material for making a stove is wheels.

You will need to find 4 identical disks. In addition to them, you will need a piece of thick iron for the tray and door, a metal pipe for the hood and a square profile cut. From the tools, prepare a grinder and a welding machine.

By the way, if you still haven’t found the time to learn welding, then take advantage of these forced days off.

Features, pros and cons of a homemade potbelly stove made from wheel rims

Nowadays it is not at all necessary to buy a home-made potbelly stove or make it yourself. You can buy it ready-made in the store. Moreover, some options look quite nice, and in the door area they have tempered glass, which allows you to turn such a stove into an impromptu fireplace and watch the flames. Yes, even ordinary potbelly stoves from the store, without glass, look quite good. But the question of quality remains open. You can buy the cheapest stove, but it will quickly burn out - a waste of money. And high-quality potbelly stoves will definitely not be sold for next to nothing.

Potbelly stove from the store

In addition, a good modern potbelly stove is made as safe as possible, which also increases its cost. Previously, the combustion intensity was regulated by opening the door, now - with special valves, which increased the level of safety when using the device. In addition, good store-bought stoves are much more economical in terms of fuel consumption than homemade ones. The chimney is also designed differently: now potbelly stoves have special smoke chambers or special systems, due to which the pipes rarely burn out. In smoke chambers, the smoke has time to cool slightly before being released into the environment.

We still suggest making a potbelly stove with your own hands, but one that will be reliable and durable. It won’t take long, but you will have much more confidence in such a stove than in a cheap store-bought version. So you will not only save money, but also be able to work in a warm garage for more than one season.

Potbelly stove made from wheel rims

For example, from wheel rims you can create a high-quality and durable potbelly stove. Its advantages:

low cost - to create such a product you will not need to purchase any special materials;
durability - car wheels are very thick and durable;
heat resistance - the alloy that is used to create disks can easily withstand very high temperatures;
high heating rate - such a potbelly stove quickly warms up to the required level and quickly warms up the room (efficiency reaches 85%);
unlimited in size - to create a stove you can use 2-4 or more disks depending on your requirements.

This design, of course, also has disadvantages. To make such a potbelly stove, you need welding skills and a welding machine. In addition, the product retains the other disadvantages of any stove of this type: fire hazard, rapid cooling.

It is also important to consider some features. Thus, the distance between the lower part of the firebox and the grate to the first barrier to smoke (the upper part of the firebox) should not be less than 45-50 cm. If you have to heat the stove with raw wood, then it should be even greater - 65-80 cm. The need to withstand This distance is due to the fact that the smoke, coming out through the chimney too quickly, takes away the lion's share of the heat. The result is a decrease in efficiency. Also, because of this, a lot of carbon deposits and soot are formed inside the furnace, which also reduce the efficiency and increase the fire hazard of the furnace.

Scheme of a potbelly stove made from rims for a car

Low-quality fuel, garbage and waste are often used to fire a potbelly stove made from disks, and the optimal size of a stove for a garage is far from the largest. That is, in many cases it is simply impossible to make the combustion chamber high. In this case, it is easier to make a special grate structure assembled from thick steel or reinforcement. It is placed inside the oven, leaving a small gap of 5 mm to take into account the thermal expansion of the materials. Thanks to such a grate, you can solve the efficiency problem of a small stove.

On a note! If the oven is oriented horizontally, then grates are not installed in it.

Design Features

Using welding, you can build a practical stove from wheel rims.
A potbelly stove made from disks is structurally no different from its analogues made from steel sheets and gas cylinders. A special feature is the small height of the product. As a rule, it is cooked from two or three fragments, since an increase in the number of seams weakens the strength of the device. Because of this, pyrolysis gases do not have time to burn in the furnace, and when leaving the furnace they settle on the walls and pipes of the structure, forming flammable soot. This substance reduces the heat transfer of the fireplace and is fraught with fire, fire and even explosion.

To reduce the amount of soot, the grate is lowered as close to the bottom as possible, and the draft is increased by increasing the length of the chimney pipe. This approach makes cleaning the device easier and makes it completely safe.

How to assemble a potbelly stove body

So, you will need 4 disks, but three of them will need to be worked in a special way.

In the disk that will be below, you need to cut a hole and make a removable tray for removing the ashes

In the side of the disk you need to cut out a half ring with a grinder, as shown in the photo. This half ring will become the basis for the pallet

Measure the inside of the disk, make a template and cut a piece of thick sheet metal along it to create a circle that can then be welded to the half ring

To easily remove the tray, you need to attach a handle to it. Even an ordinary door or any other suitable metal bracket will do. It can be secured by welding or bolts, whichever is more convenient for you.

The second disk is installed on the lower one with the rim down, there is no need to redo anything, and ash will then spill into the tray through the ventilation holes

But in the third element, the rim needs to be cut so that the disk turns into a metal ring. Its task is simply to make the firebox higher so that fuel can be refueled

Three discs are installed in this sequence: first the one with the tray, then the usual one without changes with the holes down, and finally the ring

The final, fourth disk must be placed with the holes facing up, then all the small ventilation passages will need to be welded and only the axial one will be left, to which the exhaust pipe will be attached. The entire structure must be fastened by welding, making continuous seams. This is where you can practice with a welding machine.

The furnace body is ready, you just need to make a few additions.

Instructions

At a certain point in construction, the question arises of how to properly construct a potbelly stove yourself. A 200 liter barrel just becomes one of the most suitable frames. The stove can be distinguished by shapes and sizes; it can be round, square, located horizontally or vertically. It all depends on your imagination and the room.

Vertical model

Vertical stoves are manufactured in the following sequence:

Preparing an opening on the side of the barrel to make it possible to load fuel.
You can purchase the door in advance or try to replace it with a cut-out part from the wall of the container - welding a handle and hinges to it for ease of opening and closing the firebox.
Just below the door, cut an additional hole to install the blower door. To create a blower, a thick-walled pipe is used, which could move along metal slats, but not be completely pulled out.
Grate bars are mounted 20 cm above the bottom of the barrel - this is a metal plate with holes; it can be replaced with a cellular part made of reinforcement. Fixation is carried out using a steel angle.
Metal legs are welded at the bottom of the barrel, or the structure is simply installed on bricks.
The role of the cooking panel is performed by steel wire; it is welded to the top lid of the oven.
To protect the walls from burning inside, the firebox can be lined with refractory bricks, giving it the shape of a semicircle using a grinder. The masonry is done with a special oven mortar, which contains part fatty clay and two parts sand. This mixture is diluted with the minimum possible volume of water, it should turn out very thick.
Then the chimney is formed. The hole for the pipe is at least 15 cm in diameter, usually made on the side or top of the barrel. The height of the pipe is more than 4 m. To reduce the load on the body, the chimney should also be secured to the wall.
You can make a rotary or moving valve on the chimney. It will help to quickly adjust the removal of heated smoke, completely blocking the chimney when the stove is not working.

Vertical oven

Horizontal model

From a barrel with a volume of 200 ml you can also make a device for heating a room, which would have a horizontal location

First, it is important to prepare the structure to support the frame. The height is calculated taking into account the operating characteristics

When choosing this indicator, you should first pay attention to the area of the room where you plan to install a homemade potbelly stove

The drawing always takes into account the specific placement of the furnace. The assembly of a horizontal unit is carried out almost identically to a vertical one. In more detail, the process includes the following steps:

It is necessary to form a hole in the bottom of the prepared barrel, which will be used to remove ash

It is important to understand that its size should not be too large. Now you need to build an ash pan

Its dimensions should not be more than a third of the height of the canister

The height of a 200 liter barrel is 85 cm - the calculation is based on this parameter. The material you need to choose is a regular sheet of metal that would be suitable in thickness. It is connected to the bottom of the heating device. Welding equipment is used for this. To arrange the ash pan, it is necessary to provide another viewing window; the compartment must be cleaned through it. Then the installation of the chimney structure is carried out. The two most popular pipe locations are on the back wall or on top.

Horizontal oven

A long-burning potbelly stove, which is placed horizontally, can be used not only for heating garages, basements, and various buildings, but also for cooking and heating food. For this purpose, it is supplemented with an arched panel. The device turns out to be mobile, so you can even take it with you into nature.

Why are rims ideal?

Stoves for cauldrons are made not only from disks. For production, you can use a metal barrel. But it is too thin, so a strong fire can simply burn through its walls.

Another option is to use a steel sheet, choosing the desired thickness. This design will be reliable, but will also come at a store price.

The best option remains car wheels, which you may have lying around somewhere in the garage. In addition to its low cost, such a stove for a cauldron has many other advantages:

materials for production are always available;
the car disk is made of durable steel of sufficient thickness, so the stove will last for many years;
car rims are resistant to high temperatures and open fire;
the steel from which the disc is made heats up quickly;
since there are disks of different diameters, the structure can be made to the desired size;
From car wheels you can make a stove not only for cooking, but also for heating small rooms or for lighting a bathhouse.

Another significant advantage is that a homemade stove can be made without experience. The only tools you will need are a welding machine and a grinder.

Which potbelly stove is better - cast iron or steel?

The choice is truly difficult, because each material has its own advantages and disadvantages.
To decide which potbelly stove is best for you - cast iron or steel, you should familiarize yourself with their characteristics. 1) Cast iron stove.

Flaws:

cast iron is a fairly fragile material, it is easier to accidentally damage it;
the cost of a cast iron stove is higher than a steel one;
it is almost impossible to repair a cast iron firebox if it is damaged;
high sensitivity to sudden temperature changes - you should be careful, for example, from getting cold water on hot cast iron to prevent cracks from appearing;
does not have a very attractive appearance;
relatively heavy weight (heavier than steel);
has a relatively large rate of thermal expansion (the dimensions of the oven can increase by several centimeters when heated).
Cast iron stove

Advantages:

has a very good heat capacity (heats up quickly and gradually releases heat);
is not afraid of high temperatures, which means it does not burn;
has a longer service life if handled carefully - well adapted to constant, long-term loads;
maintain heat well in smoldering mode (therefore it is better to add fuel in small portions);
does not lead to active burnout of oxygen in the room, because Cast iron is chemically neutral (also due to this, it is not susceptible to oxidation - rust).

2) Steel oven.

Flaws:

steel is susceptible to corrosion, so usually the service life of steel furnaces is 5-7 years (after which they require repairs);
does not withstand high temperatures very well - the metal can burn out, come apart at the seams or become deformed;
not all types of fuel can be used (for example, the use of coal is contraindicated);
despite the fact that steel furnaces heat up quickly, they are not able to retain heat for a long time;
does not distribute heat very evenly (close - hot, at a distance - cold);
actively burns out the oxygen contained in the air (therefore, a constant supply of fresh air from the street is required);
does not hold up well to regular long-term use;
Steel furnace
has the lowest fire safety among similar devices.

Advantages:

steel stoves are easier to repair - this can be done at home, using an ordinary welding machine;
The weight of steel stoves is noticeably less than that of cast iron;
they have a more attractive appearance;
they are more resistant to mechanical stress;
steel furnaces have a lower cost;
it is easier to make such a stove (or a fireplace with a steel firebox) yourself, and its design can be very diverse;
compact dimensions.

There are also hybrid varieties of potbelly stoves: their firebox is made of cast iron, and the outer casing is made of steel.

In the interior

Step-by-step guide to making a stove

Inspired by the fact that you will independently make a necessary thing in the household, and having taken the necessary tools and materials, you can begin to make a stove for a cauldron.

We weld the disks together

It is worth noting that a design made of aluminum wheels will not work; you need to take two steel wheels.

First we make the upper part of the furnace. Turning the disc with the mounting pad up, use a grinder to cut a circle through the bolt holes and pull out the middle. As a result, you will get a stable surface on which to place the cauldron.

The second stage of work will be making the bottom of the stove. We turn the disk so that the mounting platform is at the bottom, and place the upper part of the stove on top, which we made in the previous step. Weld two disks together in a circle.

Assembled furnace from disks

In order for the stove to be lit, you need to cut a hole about 20 by 12 cm in the lower part. To make the structure durable, make a hole two centimeters higher from the bottom edge. The cut out part will serve as a good door for the combustion chamber.

To ensure stability of the structure, you need to weld three footrests to it, the length of which is about 20–30 cm. Steel corners can be used as a material.

To make the stove easy to carry, weld handles to the sides.

Use a metal plate to cover the hole in the disc hub at the bottom of the stove.

This is how in a few hours you will get an excellent oven made from car wheels, which is well suited for preparing your favorite dishes.

Main stages and important features of furnace laying

From the moment the foundation is poured to the start of construction, 3-4 weeks should pass. During this time, the base will gain the necessary strength and will be able to withstand the weight of the brick oven. The work in question requires maximum responsibility and concentration on the part of the performer. Any mistakes can lead to irreparable consequences, so get ready for the work in advance and allocate enough time to complete it.

DIY brick oven

The laying of the furnace is carried out in several stages.

First stage. Lay out the ash pan and the lower part of the first cap from brick. Carry out the laying using the previously discussed sand-clay mortar.

Second phase. Install the ash pan door into the masonry. Use galvanized wire to secure the door.

Install the ash pan door into the masonry

Third stage. Install a grate over the ash pan chamber.

Install a grate over the ash pan chamber

Fourth stage. Mount the firebox. Line the inside of this compartment with fire bricks. Place the bricks “on edge”. At this stage you need to use a special masonry mortar. It is prepared in the same way as the standard one, but instead of simple clay, refractory clay is used, i.e. fireclay. Secure the combustion chamber door using a steel plate and the wire you are already familiar with.

Fifth stage. Continue standard laying until you reach the 12th row. Having reached this row, close the combustion chamber and lay the tiles with burners evenly. This stove must be made of cast iron. Check the evenness of the installation using a building level.

Sixth stage. Lay out the first cap. It is erected at the left edge of the stove. At the same stage, a canal for the summer passage is being built.

Seventh stage. Install the stove and line the walls of the cooking compartment. Lay out the previously mentioned lower cap.

Eighth stage. Install the valve for the mentioned summer passage channel. This valve is located in the inner corner of the cooking compartment.

Ninth stage. Lay the masonry up to the 20th row. When you reach this row, close the brewing compartment and the first hood. Be sure to leave the required number of holes in the solid masonry for the summer passage and lifting channel, as well as the vent for the cooking compartment. Place the bricks on steel corners - this will ensure higher strength and reliability of the stove.

Tenth stage. Close the portal of the brewing compartment with hinged fireplace doors. It is better if the doors have heat-resistant glass inserts. This solution will allow you to monitor the fuel combustion process and admire the flame.

Eleventh stage. Install cleaning doors for easy soot removal. For installation, choose a location that is easiest for you to get to.

Twelfth stage. Lay out the walls of the hood almost to the top edge of the wall opening. Cover the top of the stove with a couple of rows of bricks. Fill the gap between the top of the stove and the jumper with mineral wool. Thanks to this, additional thermal insulation will be provided and heating efficiency will be slightly increased.

Thirteenth stage. Place a decorative band around the upper perimeter of the unit.

Fourteenth stage. Proceed with the installation of the chimney. It is better if the chimney is made of brick. This design will last much longer than the same metal or asbestos pipes.

Heating and cooking stove

Thus, although laying the stove is not a simple task, it can be done with your own hands. It is enough to simply understand the technology and follow the instructions in everything. Remember, the materials for work must be of the highest quality. And stove designs that have been tested over the years will allow you to independently build a unit that will efficiently heat your home for many years without any problems or complaints.

Good luck!

Materials and equipment for work

When welding a furnace from car wheels, the following list of materials and tools is used:

rims of a truck or car, 2-4 pieces;
welding machine;
welding mask;
gloves;
pipe with a diameter of 16 cm, length about 3 meters;
chimney;
metal sheets for creating air reflectors;
metal legs in the amount of 7 pieces;
hinges and handles to create a door;
fuel container.

When creating a combination oven or other types of oven, additional materials may be required.

Which type to choose for yourself

Taking into account the above-mentioned features, it is necessary to correctly select the appropriate type of disk furnace. The need to independently construct a furnace from car rims occurs in the following cases:

If you need to heat small non-residential premises, for example, a country house or a workshop. The use of high-quality rims will allow you to achieve maximum quality of the furnace, and will also significantly simplify production.
If you need to equip the main “fire” part of the furnace structure without using expensive heat-resistant steel.
If you are going to use the stove for cooking. In this case, you will have to make a stove for the cauldron from car wheels.

Most often, car wheels are used to create mobile (portable) outdoor and garden cooking stoves, as well as for arranging fire pits. The simplest version of a disk hearth stove involves the use of a large mass and side height, which significantly improves heat transfer rates and provides reliable protection from the effects of wind.

Doors, legs, exhaust pipe

You need to install three doors on the furnace body: the bottom one, through which air will flow and ash will be removed, and two upper ones.

For the ash pan, use a grinder to cut a rectangular hole directly in the lower disk. Along the perimeter of the hole, you need to fasten metal plates that will form a box. The door will be held on it

An important point: the door handle must be fixed in different positions to regulate air access to the firebox Prepare 4 identical pieces of pipe for the legs of the potbelly stove Weld them to the bottom of the stove at an equal distance and slightly inclined so that the stove stands very firmly For the fireboxes, prepare two boxes with doors and handles with locks

The openings of the fireboxes will be located on the first and third disks from the top. Make them on one side of the stove with an ash pan, so as not to run around the structure during maintenance. Place ready-made boxes on the holes and weld them along the contour. In the top cover of the potbelly stove, you need to cut a hole for the exhaust pipe with a grinder, having previously measured it along the contour. A piece of pipe is welded into the hole, and a metal corrugation is connected to it, which is led outside the room

At this point, the assembly of the structure is completed. Now, if the aesthetic component is important to you, the stove needs to be brought into a condition worthy of use.

How to use it correctly?

We install our structure in a tray. Cooking on the stove right away is not recommended. The discs are usually painted and retain oil and brake fluid. Therefore, to prevent the pilaf from smelling like burnt chemicals, the oven is first calcined. To do this, through the top, the firebox is completely filled with firewood. I use lighter fluid, light the flame and let the wood burn completely.

Now, after letting the stove cool, pour out the ash and remaining wood. Using sandpaper and a metal brush, we clean the walls of the oven, removing any remaining paint and carbon deposits. Having completed these works, you can start preparing pilaf and other delicious dishes with the smell of burnt wood.

Now the firewood is put into the firebox through the door. After laying down some tree bark and wood chips, light the flame. Oxygen enters from below through holes in the disk, providing the flame with air supply, and from above, exhaust gases and smoke are discharged into the chimney. This design creates sufficient draft and good combustion conditions.

Cooking process in a homemade cauldron

When preparing dishes, it is important not to add a lot of firewood, maintaining a constant heating temperature in the stove. To do this, do not try to lay a large amount of firewood at once.

High flames will burn food and upset the cook. Everything will come with experience, don’t be afraid to experiment, but it’s better to spend a little more time gradually adding firewood to the firebox than to end up with burnt meat or pilaf.

After cooking, do not immediately begin maintenance and cleaning. It is necessary to let the metal cool, and only then begin to clean out the ash and unburned remains of firewood, pouring them into the tray through the holes in the lower disk. To remove large cinders, you will need to turn the stove over and shake out the waste into a tray. The ash is used to feed garden plants and flowers.

For ease of movement around the site, the stove can be installed on wheels. It all depends on the imagination and skills of the master. This design can be used for frying meat in a frying pan and preparing first courses. But the masterpiece was and remains the oriental crumbly pilaf, which will be prepared for you by a stove for a cauldron made from disks, made by yourself.

Fire safety rules when installing homemade stoves

When creating a stove from car wheels, fire safety rules are a rather sensitive topic. The technology for the production of wheel disks initially did not include their use for other needs, especially as a homemade oven.

Disc stoves cannot be made using waste oil, since metal that is not rated for welding can burst, and boiling oil with highly toxic gases will flow through the crack. Since it is impossible to extinguish the furnaces during mining, you should wait until the oil burns out.

To avoid disastrous consequences, it is recommended to cook a stove made from car wheels only with solid fuel.

You can create a completely safe horizontal potbelly stove from disks by adhering to the following rules:

The weld seam must be smooth and free of defects. Otherwise, smoke will escape through the cracks and fill the room. In addition, during operation there is a risk of failure of an improperly welded stove.
To improve quality, it is strongly recommended to weld 2 parts at a time.
After each seam, the welded parts must be given time to resolve residual internal stresses. It will take 3 minutes per kilogram of mass of elements being welded. It is recommended to begin further welding no earlier than when you can touch the metal with your bare hand 3-4 cm from the end of the seam.
A day after installing the parts, the stove undergoes a test run to resolve residual stresses. This requires at least 3 hours of burning at full power with the air throttle open.

To ensure fire safety, it is necessary to close the oven door tightly, and also place flammable items away. When leaving the room, it is important to completely extinguish the stove and clean the chimney in a timely manner.

Why are waste oil furnaces popular?

The main reason for people's love for homemade stoves is the low (or zero) cost of the unit itself and the fuel for it. Some home-grown craftsmen make such heating devices as an experiment and at the same time a useful device.

With the advent of a homemade waste oil stove, the issue of “attaching” recyclable materials no longer exists.

For especially advanced craftsmen, the production of garage furnaces for working out has become another business option. They build custom models and sell them to interested but less skilled garage owners.

How does the unit operate during testing? The process consists of splitting heavy fuel with impurities, which has a rather complex composition. In another way, the process in which there is a lack of oxygen and the combustion of not the fuel itself, but its vapor, is called pyrolysis. The operating principle of pyrolysis equipment is described in our recommended article.

To start the process, it is necessary to evaporate the fuel, then heat the resulting vapor to a temperature of about +300-400 ºС, after which combustion will occur spontaneously. All you have to do is wait for the fuel to burn completely.

There are 2 schemes that are used when making stoves independently:

filling the tank with oil and setting it on fire, as a result of which the vapors evaporate and begin to burn;
the use of a burner in which three zones (pyrolysis, ignition and afterburning) are combined and make the combustion process more efficient, controllable and safe.

The second scheme is more complex, requiring serious modification of the fuel and manufacturing precision, so we will consider simpler models from the first group.

Diagram of the design of a simple model of a furnace in production. The air necessary to support the combustion process enters through the neck with a damper. The same damper can partially regulate the combustion force

Advantages of using an oil-based garage stove:

ease of design and maintenance of the device;
fuel economy - about 1.5-2 liters per hour;
absence of soot and soot;
safety of storage of mining reserves;
it is possible to connect an air or water heating circuit;

The compactness of the unit is also extremely important for small spaces.

There are also disadvantages:

the need for regular cleaning of the stove and chimney;
a mandatory element is a vertical chimney with a height of at least 4 m;
for furnaces with nozzles, only purified oil should be used (the approximate cost of a filtered product is 8-12 rubles/l);
One of the conditions for storing mining is above-zero temperature, that is, you need either a room heated in winter or a tank buried in the ground.

Before manufacturing/purchasing a finished furnace or boiler for testing, it is necessary to consider all the pros and cons of home-made devices, and then make a final decision.

How to make a stove from disks for a sauna with your own hands

The most complex version of a potbelly stove made from disks with your own hands is considered to be a heating structure for a bathhouse. It is used to create a medium-sized sauna with heated, moist air. The sauna stove is based on a brick firebox.

The structure of the heating system is somewhat more complicated than that of a simple horizontal stove made of disks, but it is quite possible to do it yourself.

First, a brick firebox is laid. When calculating the dimensions of the masonry and foundation, they are based on the diameter of the wheels. As a rule, ordinary passenger car wheels are used, therefore the dimensions of the firebox are on average 625x625 mm. There should be a cast foundation underneath it.

Functionally, the firebox is divided into 2 parts, so you need to think through the laying in advance. Cold air from the locker room should come from below, and solid fuel materials should be thrown from above.

Drawing of a disk stove for a bathhouse.

After the firebox has been built, welding of the structure begins. It consists of 4 discs. At the bottom, struts and a reflector are installed for uniform and smooth air flow, as well as high-quality heating of the container.

The third disk is welded so that stones can be placed inside, and a metal pipe is installed in the center to remove smoke. The third and second disks are connected by legs to fix the structure. The smoke transmission pipe is attached to the bottom of the third wheel.

An air divider is installed in the second disk on top, which is necessary for heating the water. The divider is mounted on 2 metal legs. The upper disk is a reservoir for supplying warm water. A pipe of a convenient length is attached to it, and a faucet is also mounted.

There is a pipe in the center to remove smoke. The chimney is fixed to the supporting platform with struts. Under the support platform there is a sheet of galvanized iron.

This is a general scheme for welding a furnace from disks. Let's take a closer look at the nuances of creating individual parts of the structure.

Water container

The water tank is made of one wheel. To do this, it is necessary to weld the bottom and the top so that there is a hole in the center corresponding to the diameter of the pipe, the standard is 16 cm. It is also important to make an even and accurately executed seam, otherwise water will leak out of the container, and the reliability of the structure will be called into question.

After welding the container, you need to weld the pipe and check the quality of welding by filling it with water.

Arrangement of the heater and the upper part of the firebox

For complete and high-quality heating of water and stones, each intermediary disk must contain a divider or reflector. A heater is a container with a pipe in the center to remove smoke. It is necessary to completely weld the bottom, install the pipe and attach the container to the top of the firebox.

A pipe is attached to the third disk - the upper part of the firebox - using casings, and an air divider is installed inside to heat the tank.

Foundation and brickwork

The foundation of the stove should be monolithic and extend slightly beyond the boundaries of the firebox. The average foundation dimensions are 700x700 mm. The firebox is divided into 2 equal parts: at the floor level of the locker room, from where fresh air is supplied, and at the steam room level, where solid fuel materials are thrown in.

In both cases, metal doors are attached, and a combustion structure is installed between the levels.

Stove assembly

Scheme of the furnace in production.

Assembling the stove should begin with laying the firebox and welding the elements. First, the internal parts of the structure are installed - a divider and an air reflector, then the bottoms are welded to the structures for water and stones.

Then the smoke exhaust pipes are installed, after which the remaining elements are attached to each other. After complete assembly of the structure, it is necessary to carry out a mandatory test run of the furnace.

A properly welded stove will not allow smoke to pass through and will ensure uniform heating of the containers. High-quality masonry will ensure constant air circulation, which promotes rapid heating and long burning.

Installation

The use of potbelly stoves made at home, as well as any other heating installations, requires strict adherence to safety precautions. Initially, you should select a place to install the stove. This unit, as practice shows, is best installed in a corner, namely near the walls opposite in location to the garage door.

It is better to surround the stove with brick walls on all sides. Thus, the possibility of touching a hot stove will be eliminated, and the heat generated from its firebox will also be accumulated. Thus, you will increase the efficiency of the device several times.

Increasing furnace efficiency

If the walls of the garage are made of wood, then there must be a certain distance between them and the stove, namely at least 100 cm. In addition, in order to avoid fire in the building, the walls near the potbelly stove should be lined with asbestos sheets/bricks or other fireproof materials.

As a base for a potbelly stove, you can use a steel sheet with a thickness of 1–2 cm. Another option is to pour a concrete screed. Thanks to these actions, you can prevent the spread of fire if coals/sparks, etc. suddenly fall out of the firebox.

To use a potbelly stove in a garage, you must first provide it with high-quality fresh air ventilation. Fresh air must be supplied here in sufficient volume to ensure normal combustion of the fire. A small gap between the ground and the garage door can serve as ventilation. Otherwise, you will have to make a special channel for the timely flow of air into the garage, which is not very profitable from an economic point of view.

Potbelly stove with burner

If you equip your potbelly stove with a water tank, the stove can be used to heat it. By installing burners on it, you will also have the opportunity to heat food.

The entire process of making a potbelly stove will take no more than 2 hours, and you can enjoy the results of your labor for several seasons.

How to make a grill for a cauldron from car rims

Many of us love Central Asian cuisine, in particular pilaf. Classic pilaf is cooked in a huge bowl-shaped cast iron cauldron over an open fire.

For ease of cooking, you can build a small grill for a cauldron, which is already available.

There are a lot of ways to build such structures with your own hands, but in this article we will tell you in detail how to make a barbecue for a cauldron from disks that have served their time on the wheels of a car.

Design Features

Actually, the main advantage of an improvised barbecue made from a wheel rim is that the costs of its construction are kept to a minimum, and the final result is very worthy. Almost every summer resident has all the necessary materials and tools for production. The design is durable and easy to use.

For construction you will need car wheels that have already served. Since they are thrown away or scrapped, their cost is insignificant, so they can easily be found in your garage or at any service station. You will also need some metal profile to create the legs and a few pieces of metal for the central cap and handles.

Difficulties may arise only if you have never worked with a welding machine, but you can always invite a specialist to help you make a few welds.

Step-by-step algorithm

The first thing you need for construction is a pair of classic stamped car wheels made of durable metal. The sizes of the disks should be selected to suit your cauldron; option 13 may be suitable, or maybe 15, although a very large design is not needed.

Two stamped white discs

On one of the disks we mark a cutting line, exactly above the round holes, and cut off this circle using a welding machine.

The cut circle will work perfectly as a lid on which you can put pots or a kettle, so don’t rush to throw it away.

On the second disk, you need to weld the main central hole, which will require a small piece of thick metal.

Preparing the welding machine

We carry out welding work

Then the two disks are placed on top of each other and, using the same welding machine, they are connected into a single structure.

Circular welding process

This creates an impressive seam that firmly connects the two discs. To make it more presentable, you can modify it with a grinder, cutting off strongly protruding elements and grinding the edges.

In order for the structure to stand stably at the required level, you will need legs. The legs can be tightly welded to the grill if you are preparing a summer cottage, or you can make the structure detachable.

In the second case, the device will be mobile; it can be easily carried in the trunk of a car and, if necessary, assembled. Small pieces of a profile larger in cross-section than the legs themselves can act as fastenings for the legs.

These three parts should be welded to the grill on three sides (in this case, a tripod is made).

There is no need for precise calculations here; it is enough to roughly estimate equal distances and weld the necessary parts to the bottom of the grill made of disks at the same angle.

Leg clamps are welded

We also cut out the legs from metal, in particular we use a rectangular profile.

The legs themselves, cut from the profile

It is worth trying on the legs by inserting them into the prepared grooves. If they enter with difficulty, you should process the edges of the parts with a grinder, and then hammer them into the grooves with a hammer.

Note that many craftsmen advise making four supports, as they consider the tripod not a very stable structure.

Next, mark the door that will open directly into the firebox and cut it along the line.

At the next stage, you will have to use your imagination and engineering skills to create a decent hinge for the door. For example, you can make it from one bolt.

It is necessary to cut off the cap from it, then select two nuts that are screwed onto it. One nut should be welded to the door, and the second to the wall of the grill. By screwing the bolt onto the threads of both nuts, you get a convenient loop.

You can weld any piece of metal of suitable size as a handle.

You can make two loops using the same bolts, here all the work is done at the discretion of the master.

Loop manufacturing option

To make it easier to transport the grill, you should weld lugs to it on both sides, or at least on one side. Such improvised handles will allow you to comfortably carry the barbecue without fear of getting dirty with soot, soot or dirt.

For a more uniform smoke output, you can make four even cuts along the diameter of the disk. At this point, work with the hearth to form its shape is completed.

To remove paint from car rims, you should burn the resulting grill on all sides. For final processing, you can use a brush or sandpaper.

Removing paint using improvised means

Then, using heat-resistant paint, you need to paint the structure in a suitable color. Black looks very harmonious.

As you can see, making a grill for a cauldron is quite simple; there are no special tricks here. A simple and convenient design will allow you to install a cauldron and cook pilaf, and if desired, you can make a shish kebab on it using skewers of suitable length.

Furnace order

At first glance, it may seem that laying a Russian stove is a rather banal and well-honed procedure. But in fact, even in the old days it was quite difficult to find a good stove master who could create an ideal design without the slightest error. Only a properly laid out stove will serve for a long time and perform all its functions without any failures.

The most optimal arrangement is a design of 40 rows, the last two of which represent the beginning of the chimney. The first row of bricks is laid on a pre-prepared foundation in a perfectly even layer. This row is very important, since the durability and evenness of the entire structure depends on it.

The second row represents the formation of chimney channels, space for a fireplace and firebox. The most important thing here is to do everything slowly and observing all proportions. The second row is continued by the third, fourth and fifth, which are laid according to the same principle.

When laying the sixth row, a firebox door and decorative grilles are installed, which are a necessary element for proper air circulation and blowing. Durable fire-resistant brick is used to lay the walls of the firebox and fireplace. After this, the seventh and eighth rows are laid out, and the ninth row is the closing one and covers the lower passage channels.

Glossing and operating a potbelly stove

If you have a sandblaster, great! Clean the entire surface of old paint and rust.

It is better to cover the outer part of the potbelly stove with a special heat-resistant paint that can withstand temperatures up to 1000ºС. Certa and Kudo paints show good results; these brands have aerosol packaging for sale, which is very convenient

After the paint has dried, the potbelly stove is ready for use.

Nothing complicated: you lay the wood and set it on fire, and use the blower from below to regulate the combustion

The stove has two fireboxes, so you can use only the bottom or the top, for example, if you need to cook food, or both, if it is very cold

And it should be noted that the stove has a very decent appearance, one might even say vintage due to its special shape

So, practically from scrap metal you can make a very worthwhile thing for your dacha or garage. Of course, you will have to tinker for a day or two, depending on your skills, but you must agree, it’s worth it.

This, of course, is not the only option for a garage stove. To complement this topic, we offer you another master class on making a stove for a cauldron from the same disks:

Watch this video on YouTube

And we are waiting for your impressions of the author’s idea in the comments. If you have already done something similar and documented the process with photos, send us your pictures with a description, we will definitely publish the best materials!

Fuel selection

The size of the potbelly stove can be very different, but the mechanism of operation is similar for all. The combustion material is placed in the firebox.

The cheapest option is to heat the room with wood:

In the firebox of a potbelly stove, logs are placed in a cage or in rows.
Then wood chips or paper are placed in the very bottom row to light the logs.
The door is closed and the intensity of combustion is controlled by blowing.
Wood fuel smolders for several hours, so the room warms up completely and for a long time.

When installing some models of potbelly stoves, the use of waste oil as fuel is allowed.

Potbelly stove for heating a garage made from rims

We bring to your attention the third version of a homemade stove made from car wheels.

In this case, to make a mini potbelly stove you will need three identical rims from a car.

The design of the “wheeled” stove is vertical, which is very convenient for small spaces. Its main purpose is to heat the workshop and garage.

Take the first car rim and cut out the middle of it. Then we attach it to the second disk (the base of the furnace) - it turns out to be a kind of blower. We weld a handle made of a metal strip to the valve.

We cut out a door in the first disk and secure it with hinges. We weld the two rims together, placing them on top of each other (as shown in the photo below).

After this, we weld the third car disk. We cut a hole in the center to weld a pipe for installing the chimney.

The master installed a radiator between the pipe and the chimney to better heat the room.

At the last stage, all that remains is to weld the legs from the profile pipe. To collect ash, place a metal container under the stove.

As a result, we have a compact stove for the garage, which will definitely come in handy in winter.

The welded structure will need to be painted with heat-resistant metal paint. See the author's video for details.

Another option

And finally, we want to share with you one more idea on how to make a stove from disks. Moreover, in this case we will use not 3 or 4, as in the previous versions, but as many as 5 rims.

First, the surface of the rims must be cleaned with a grinder. After this, we install them on top of each other, and it will be necessary to weld them together into a solid structure.

Next you will need a square corrugated pipe. We cut two pieces of the required size from it, then make a trim at 45 degrees, butt them together and weld them.

In the lower wheel rim, using a grinder, we cut out a square “window” of a suitable size so that the corrugated pipe can be inserted inside the potbelly stove.

Thus, one part of the profile will be inside the rims, the second - outside. We cut out a “window” in it, and then weld another piece of corrugated pipe (wood will be loaded through it).

The bottom of the potbelly stove is made of sheet metal. We cut out a circle of suitable diameter and weld it to the base of the first disk.

It is necessary to cut out a cover from the same sheet metal (it will be removable, so two handles need to be welded to it).

We weld an outlet from a round pipe to the first rim for installing a chimney. We clean the seams and paint the metal with heat-resistant paint.

As a result, we got a homemade potbelly stove made from car rims for the garage.

Among the advantages of this design, it is worth noting its low cost - all the parts can be easily found on ferrous metal, and they cost pennies. And many home craftsmen have most of the materials in stock, which further reduces the cost of the stove.

For more information on how to make a stove from disks yourself, see the author's video.

Stages of work

After the preparatory part, you can safely begin manufacturing the structure.

First stage

We take three disks and cut out the middle using a grinder. The process can take a long time because the discs have an uneven shape, making it difficult to reach the middle.

Second phase

The next step will be welding. We weld a square metal sheet to the lower wheel rim. It must extend beyond the walls of the disk so that burning coal or a spark from the furnace falls onto it. This is a guarantee of fire safety.

We weld the disks together in a circle. You need to be careful not to leave unwelded holes through which smoke from the potbelly stove will escape. We also weld all the holes for the valve for the camera.

Third stage

Next, we cut out the doors for the firebox and ash pan.
We recommend cutting a hole for the ash pan in the lowest disk, and for the firebox in the second one from the bottom. The metal pieces that remain can be used as doors. There is no hole for the ash pan, so that the draft goes well, you can open the doors of the ash pan or firebox. Installation of a chimney pipe. We weld the pipe into the center of the uppermost disk or onto a sheet of iron that can be welded to the upper disk. In the second case, your potbelly stove will be more fireproof and reliable.

Fourth stage

The last step is to install the stove on the base. Its height can be equal to the height of one brick, since the entire stove does not weigh very much. First you need to make a square formwork from bricks and fill it with cement mortar. After the solution has dried, you can safely install the potbelly stove.

To ensure that the stove lasts longer and the metal does not corrode, we recommend covering the potbelly stove with a special paint that can withstand constant high temperatures. It is especially important to paint the upper part of the structure: it is there that moisture constantly evaporates, so the metal becomes more vulnerable to losing its properties.

As a result, from the maintained materials you will get an excellent, reliable potbelly stove that will heat the room no worse than a new one.

Pipe or barrel stove

An old barrel or large-diameter pipe is a fairly common material that will serve as an excellent blank for a potbelly stove. Here's what to do:

Cut two openings in the wall of the workpiece: the upper one is for loading fuel, the lower one is for cleaning the ash chamber.
A strip is welded along the perimeter of the cut out fragments - these will be the doors. To each of them you need to weld a handle and a latch.
From the inside, corner shelves should be welded to the walls of the housing approximately 100 mm below the upper opening, on which the grate will be laid.
Now we make the grill itself - we weld several steel rods.
If a pipe was used as a workpiece, you need to weld the lid and bottom to it. On the lid closer to the back you need to cut a hole for connecting to the chimney.
The legs are welded to the bottom, then the hinges for the doors and hooks for the latches are welded to the body.
We hang the doors.

Assembling a stove-stove from a pipe

The potbelly stove is ready, all that remains is to install it in place and connect it to the chimney.

In this version of the oven, as in the first, the surface of the lid can be used as a cooking surface (heating food or boiling water).

From a gas cylinder

Potbelly stove from a gas cylinder
You need to start work with a drawing, but not on paper, but on the cylinder itself. The future firebox door and vent are marked with a marker. The door should be located in the center of the cylinder, and the blower should be in its lower part. The distance between them is maintained no more than 10 cm, and a closed line is drawn in the middle. Using a grinder, the cylinder is cut into two parts.

457aaeec8f9bdc43302076c2d06e9114.jpe

A grid is welded from 16mm reinforcement and welded to the lower half, after which both parts of the cylinder are joined again.

In the places intended for loops, cuts are made. Then the hinges are welded there and the door is cut out. The same operation is carried out with the blower.

All that remains is to install the chimney. To do this, the valve is cut off with a grinder, and a metal pipe is welded in its place, the diameter of which should be 80-90 mm. The chimney cuts into the garage hood system or is vented out through the wall.

Ready-made potbelly stove from a cylinder

From a milk flask

Scheme of a potbelly stove from a flask

A metal can is an excellent household item, suitable for storing paints, motor oils, and fuel. The design of the flask is ideal for making a potbelly stove from it, but as a heating device it will not be as durable as we would like, its walls are not thick enough. We can confidently say that it will be enough for 2-3 seasons.

To make a potbelly stove yourself, you need to perform several operations.

First you need to mark and then cut out a hole for the chimney in the lower part of the can, almost at the very bottom. At the final stage of work, the pipe is tacked by welding. The chimney diameter is selected from 8 to 12 cm. The chimney is extended after the stove is manufactured and installed.

The can lid is a ready-made oven door with a good latch; all that remains is to drill a few blower holes, the diameter of which can be 15-18 mm. This is done at the bottom of the lid.

4 legs of equal length are made from a corner or pipe scraps, which are then symmetrically welded to the bottom of the can. You can lay a metal sheet in front of the door so that an accidentally falling ember does not fall on flammable material.

The handles of the flask are a convenient thing for carrying a potbelly stove from place to place; by grasping them you can easily shake out the ash accumulated in the stove. It is for this operation that it is better to make the chimney detachable.

Well, that's all, all that remains is to test the new stove.
