How to make a biofireplace with your own hands: device, diagrams and step-by-step assembly instructions

The contemplation of living fire is mesmerizing. A well-known proverb states that you can do this endlessly. The dance of the flame calms and pacifies, helps to collect thoughts. Unfortunately, such luxury is practically unavailable to those living in apartment buildings.

Setting up a wood-burning fireplace is not affordable for everyone. A good solution is to assemble a biofireplace with your own hands, while saving on the purchase of a ready-made structure. If you have never done this kind of work, our article will be a good help - here we looked at the structure and operating principle of a biofireplace, the main types of design, which will help you decide on the optimal scheme for assembling a homemade product.

They also provided detailed instructions for making a fireplace with your own hands, illustrating it with step-by-step photos and supplementing it with useful video recommendations. Thanks to a step-by-step analysis of each stage, even a novice master can assemble a biofireplace.

What is a biofireplace and its functions in the interior of an apartment and house

A bio-fireplace (eco-fireplace) is a device designed to heat a room and runs on environmentally friendly fuel.
Does not require installation of a chimney or hood. It can be installed in an apartment with any interior style and will bring a note of comfort, tranquility and harmony to it. You can make your own eco-fireplaces from inexpensive scrap materials. When installing a biofireplace, it is not necessary to install a chimney and hood

Designs for decorating and heating a room can be small or large-sized

With their help, they design recreation and relaxation areas, focus attention on some element of the interior, and are often used as attributes of a romantic evening. No permits or approvals are required for their installation in city apartments

Manufacturers of eco-fireplaces offer a wide range of models. There are designs that are remotely controlled and equipped with a fuel consumption system.

Advantages of eco-fireplaces:

• when heating the room, they do not reduce the level of air humidity;
• do not require complex installation;
• 100% heat transfer, since heat loss when passing through the chimney is eliminated.

Advantages and disadvantages of products

The main and undeniable advantage of eco-fireplaces is that visually they can replace a natural fireplace and create a feeling of coziness and comfort in an apartment or privatized house. Other advantages look like this:

• the design is simple and reliable, there is nothing to break in it, which means there will be no need for repairs;
• due to the smokeless combustion of a minimum amount of fuel in the room, there is no need to install a chimney;
• hot coals do not fly out of the combustion chamber and, in general, the device is considered fireproof if the manufacturer’s instructions are followed;
• ease of use.

Elite and prestigious models of biofireplaces are equipped with electronic control units, which make it possible to check the operation and remaining fuel on the monitor, automatically ignite and extinguish the flame, and also control the device from a distance using a mobile phone. They also have safety systems installed - protection from children and animals living at home, from tipping over, and so on. But the prices of such products start from 3000 USD. e.

Now about the disadvantages of biofireplaces:

1. The burner hardly heats the room. The flame is real, but very little heat is released due to the slow burning of a small volume of fuel.
2. Fuel supplied to order and sold at points of sale is quite expensive. Very inexpensive bioethanol in a liter container costs from 7 USD. e., and a branded one with the smell of coffee from the Kratki brand - 16 USD. e.
3. No matter how little combustion products are released, supply and exhaust ventilation is first necessary to remove them.

Fuel for biofireplace

In terms of its basic technical characteristics, the biofuel used in special biofireplaces is very different from those liquids that are used in classic wood-burning heating devices.
Denatured ethanol, which is safe for the environment, is used to produce fireplace fuel.

Such fuel is advantageously distinguished by the formation of very beautiful and even flames without the release of by-products such as soot, soot, smoke or fumes. As practice shows, the efficiency of high-quality biofuel exceeds 90-95%.

The best proven biofuels are those produced by manufacturers in Germany, Holland and France. Their products fully comply with all quality standards, are completely safe to use and allow you to achieve a high level of room heating at minimal cost.

Depending on the design features of the fireplace device, biogas can be used as fuel, as well as bioethanol and biodiesel liquid obtained by processing vegetable and animal fats.

Biofuel is sold packaged in special containers of different volumes.

Many modern manufacturers bottle fireplace fuel in containers that have a very convenient scale for flammable liquid consumption.

Some domestic and foreign manufacturers specially add sea salt to fireplace fuel, which creates the crackling effect of stove logs, as well as special additives that guarantee an attractive and absolutely even orange color of the burner flame.

Availability of franchises

As a rule, customers are more willing to purchase products from well-known brands, so if you want to engage in large-scale production of products, you can ensure their quick sale by purchasing a franchise. In this case, you will be provided with assistance in organizing a business, marketing support, provision of production machines, as well as their maintenance.

Instructions for making a bio-fireplace with your own hands

In this section we will look at how to make a bio-fireplace with your own hands.

The entire process of self-manufacturing a tabletop heating fireplace powered by biofuel is represented by several stages, including the assembly of the fuel block and glass chamber, as well as the final design and decor of the completely finished structure:

• At the first stage, it is necessary to build a fuel block based on a ready-made or self-made metal box, which must be painted from the front with high-quality metal paint.
• The inside of the fuel tank must be thoroughly cleaned of dust, rust or welding deposits, but painting it with paint is strictly prohibited, since otherwise there will be an active release of toxic components during combustion.
• At the next stage, all pre-prepared glass blanks are combined. High-quality silicone sealant is used for connection. After the adhesive is applied to the ends, supports are used, which allows you to obtain the most durable and reliable fastening of the parts.
• As a rule, the layer of sealant hardens completely within 24 hours, after which you need to carefully remove all excess and sagging using a regular blade, stationery or thin penknife;
• At the next stage, it is necessary to properly prepare fireplace biofuel, which, for the purpose of safe operation of the heating device, must be poured into a metal container and installed in the bottom of the metal fuel block. A wick cord is required. As necessary, the fuel container is replaced with a new portion of liquid for burning the tabletop fireplace.

At the final stage of manufacturing, you need to make a cover for the heating box yourself. It is best to use a fine-mesh construction metal mesh for this purpose, which should be cut in accordance with the dimensions of the box.

Design of a homemade biofireplace

A mesh with a large mesh can be laid in two layers, after which the lid is fixed with thick wire. In this case, adding biological fuel is carried out using a conventional medical syringe.

To give a tabletop heating device a finished look and improve its external characteristics, all kinds of decorative elements, represented by decorative stones or pebbles, are used.

Laying such natural stones on top of the mesh not only creates an attractive design, but also helps to achieve the most efficient and uniform distribution of thermal energy.

Manufacturing of the fuel block

The simplicity of the design of the alcohol hearth allows you to make it with any size and configuration suitable for the interior of your apartment

There are several points that you should pay attention to when making a biofireplace with your own hands:

The capacity of the tank and the duration of combustion depend on the size of the fuel block; the size and length of the gap in the tank lid determines the size of the flame and also affects the consumption of bioethanol; the tank must be completely sealed and well secured to prevent it from tipping over; During manufacturing, it is important to ensure safe refueling of the biofireplace; An open fire should be fenced off, preferably on all sides using glass.

If you follow the technology for producing biofireplaces, you first need to make a sealed container from sheet stainless steel. You cannot do without welding work; it is best to perform it semi-automatically in an argon environment. Then the seams will be neat and at the same time sealed. First, a sheet of metal is marked according to the given dimensions, and then bent at an angle of 90° to form a box, and the lid for it is cut out separately. To make a biofireplace fuel block, you can take the following drawing as a basis:

The joints on the sides are thoroughly boiled and checked for permeability. Then a second smaller container is placed inside, making many holes in its bottom. Inside this container is absorbent material. Then a perforated sheet of metal is placed on top, the lid is welded and the damper is installed. To close it, you should make a small poker with a handle. The finished product looks like this:

All that remains is to complete the decorative design of the product. As mentioned above, it can be built into the fireplace portal and lined with stones or artificial firewood. It is impossible to list all the design methods; it all depends on your imagination. The main thing is not to use flammable materials. One of the original methods of manufacturing and designing a decorative bio-fireplace is shown in a video filmed in the form of step-by-step instructions:

And if you want a large bio-fireplace?

With large fireplaces, of course, there is more hassle. First you need to place the wall and cut out what you need from the drywall. If the wall is not made of plaster, then hollow out the millet. Next, you need to make a frame for the fireplace - it can be the same drywall (do not forget to secure the frame).

To assemble large fireplaces, still purchase a specialized fireproof box. This miracle is sold in special stores. We must not forget that between the frame and the box it is necessary to lay out a fire-resistant material, at least mineral wool. And it’s better to buy a special, large burner. This option will still be cheaper than buying a solid fireplace. We cover it with fireproof tiles or stone. You can look on the Internet for photos of a bio-fireplace and how to decorate it.

As you can see, making a bio-fireplace with your own hands is not that difficult, the only thing is that now it’s always worth purchasing oil for bio-fireplaces. Other oils are obviously unhealthy or leave behind soot.

Advertising and sales of goods

You can advertise your products in several ways:

• placing advertisements in print media;
• distribution of booklets and leaflets;
• Internet advertising;
• creating your own website;
• advertising on radio and television.

To attract potential clients, it is recommended to establish cooperation with construction companies and teams, through them you will reach buyers. In addition, you can sell goods directly to builders, who will act as intermediaries.

How to make a bio-fireplace with your own hands - step-by-step instructions

In appearance, a floor-mounted biofireplace can be indistinguishable from a real one, made of brick and having a chimney. The design of the housing can be different:

• with columns;
• with projections;
• have the shape of a bowl or cabinet with legs.

The base of a biofireplace is easier and cheaper to build from plasterboard and metal profiles. From these materials you can make a geometrically regular, semicircular or wavy body. Instead of gypsum board, you can use wood, durable plastic or metal.

Design and drawings

At the design stage of the biofireplace, its dimensions and installation location are determined. Floor structures are stationary, so you need to choose a place so that the fireplace fits harmoniously into the interior after changing the design of the room or purchasing new furniture. For small-sized apartments, medium-sized floor structures indicated in the drawing are suitable.

The drawing will help you quickly produce all the necessary parts for the fireplace.

Case manufacturing

To install the biofireplace body you will need:

• plasterboard 9 mm thick;
• metal profile PP 60/27;
• self-tapping screws;
• screwdriver;
• serpyanka;
• primer;
• putty;
• spatula with a narrow metal blade;
• roulette;
• ruler;
• bubble level at least 80 cm long;
• pencil or marker.

Suitable for decorating the case:

• fake diamond;
• ceramic tile;
• plastic panels “brick-like” or “stone-like”.

Housing installation steps

1. Marking the wall and floor. Based on the previously drawn up drawing, mark the corner points of the back wall of the fireplace on the wall and connect them with straight lines. Mark the location of the front wall of the cabinet on the floor.
2. Frame installation. Build a structure frame from a metal profile. Keep in mind that the planks should not be in close contact with each other. There should be a gap of 2–3 mm wide between them. This will prevent the structure from distorting during heating and cooling.
3. Frame covering. Using a jigsaw or a utility knife, cut the gypsum board sheets to the required sizes. Attach them to the metal profile frame. “Down” the caps of the self-tapping screws into the gypsum board by 1–2 mm.
4. Preparing drywall for finishing. Cover the joints of the gypsum board sheets with glass-woven mesh tape - serpyanka. Apply putty in the places where the screws are installed and cover with a thin layer of serpyanka. After the putty has dried, start sanding it. To do this, use a special trowel with a sanding mesh.
5. Housing cladding. Cover the body of the bio-fireplace with the previously selected facing materials.

Installing the fuel block and burner

You can make a metal container for the fuel block yourself from stainless steel 2 mm thick. It is necessary to make a rectangular structure with a bottom and low sides. The dimensions of the block must correspond to the dimensions of the housing.

The burner is a metal cartridge that is installed in a container. Together they form the fuel block. An important element of the burner is the perforated damper, which is used to extinguish the flame and regulate its intensity.

When making your own, consider the following:

• the burner must fit freely into the metal container;
• the top panel of the burner may be a metal plate with slots;
• The internal cavity of the burner can be filled with mineral wool insulation or medical wool.

Operating principle of the fuel unit:

• Eco-fuel is poured into a metal container;
• The burner filler absorbs liquid;
• ignite fuel with a lighter.

Fireplace decoration

A protective screen made of ordinary window glass with polished edges is installed on the front wall of the biofireplace. The fuel block is decorated with ceramic firewood or stones.

How to make a floor structure

The floor design fits into any design, as it copies wood-burning fireplaces

The advantage of floor-standing biofireplaces is their variety of sizes and shapes. They resemble a geometric shape, a bowl or a nightstand, and remain stationary or mobile. But the heating unit for them must be made of metal. The body itself can be made of stone, wood, plastic, ceramics or plaster. The main thing is to ensure that the fire does not affect flammable parts.

Related materials and tools

• heating unit;
• non-flammable gypsum board (1 sheet);
• metal profile with guides and rack elements (8 – 9 m);
• dowel-nails, self-drilling screws for metal and with a countersunk head;
• heat-resistant tile adhesive, putty;
• scissors for working with metal, a screwdriver, a knife for cutting plaster;
• insulation materials (2 sq.m);
• ceramic tiles;
• grout (about two kilograms);
• construction level, tape measure;
• wood or other material for the fireplace mantel;
• decor for decorating a finished bio-fireplace.

All calculations must be made taking into account the size of the space for the future bio-fireplace. One of the views is shown in the drawing.

Preparation work

The drawing must be created taking into account fire safety

In this embodiment, the arrangement of the combustion chamber is calculated

At this step, you need to decide on the size and design of the biofireplace: large or small, wall-mounted, corner or located in the middle of the room. After which a drawing or sketch is created taking into account the fire safety of the object. When calculating its dimensions, it is necessary to ensure that the distance from the hearth to the walls of the structure and the fireplace shelf is at least 15 - 20 cm. After which, based on the drawing, markings are applied to the wall and floor.

Detailed manufacturing instructions

The process takes into account the implementation of several stages: from attaching the profile to decorating the sheathed plaster

• Frame assembly. Based on the finished markings, pre-prepared UD profiles are recorded. Then rack-mount parts are placed in them, which are subsequently fastened with self-tapping screws. Using a plumb line, verticality is controlled.
• Fastening profiles to the wall using dowels and nails. In this case, the racks are additionally secured with jumpers.
• Laying insulation material into the walls of a building. They will use compressed stone wool.
• Plaster sheathing. To do this, you need to apply markings to the plasterboard sheets and cut off unnecessary parts using a specialized knife. The main thing is to make an incision on one side, breaking the material on the other. When creating the sheathing of a future structure, it is necessary to tighten self-drilling screws at a distance of 10 - 15 cm from one another. Upon completion of this work, it is necessary to apply a gypsum-based plaster mixture.
• Biofireplace cladding. To do this, the walls and bottom of the housing are covered with tiles, except for the recess for installing the burner.
• Grouting joints. After it, a mantelpiece is installed, and the structure itself is decorated with prepared decorative components - stucco molding, mosaics, facing bricks.
• Burner installation. It can be selected or made without outside help from a metal glass in which the wick is lowered. In the latter option, you won’t be able to adjust the flame height, but you don’t need to pay for a factory design.

If you have time, desire and an inverter device, you should build a fuel block with a valve yourself. The principle of its operation is the same, only such a burner should consist of one or two chambers connected to each other by perforation. In this case, it will no longer be the fuel that burns, but its vapor, but this will allow you to control the intensity of the flame.

The last step could be the installation of a forged or fire-resistant glass fireplace grate, which will provide an additional safety feature for family members.

Due to the massiveness of floor-mounted bio-fireplaces, they are often designed in the form of corner structures. The latter can be symmetrical or asymmetrical, when a column is placed instead of one of the back walls near the fireplace. Their installation practically does not differ from the installation of standard floor-mounted biofireplaces, except for the drawing.

What it is?

The biofireplace is a bladeless design that burns not wood, but liquid fuel. The history of biofireplaces dates back to ancient times; the prototype was oil lamps or special vats of oil.

In order to please yourself with a bio-fireplace, you do not need to build a chimney, but only periodically ventilate the room. After all, this is fire, and it still takes oxygen. Moreover, biofireplaces come in several modifications, which will allow you to make your dreams come true:

• large floor fireplaces, the same size as regular ones;
• lightweight fireplaces that effortlessly cling to a wall or ceiling, but only the fireplace will be enclosed with special glass for safety purposes.
• small bio-fireplaces that easily fit on a table or cabinet and harmonize perfectly with the interior.

This type of fireplace has a simple design, but is quite expensive. You can find a way out of the situation and how to make a fireplace with your own hands, especially since the materials for it are sold in every hardware store. To do this you need the following list:

1. Glass. To do this, you just need to go to a regular glass workshop. Of course, the volume and dimensions will depend on your idea.

2. Silicone sealant, which is sold in every hardware store.

3. Metal box or can for flammable liquid. In most cases, such a device is available on the farm.

4. Finishing materials: decorative stone, decorative brick, etc.

5. Wick cord.

Before you take on a bio-fireplace, you need to make at least a rough drawing or search on the Internet.

The most important part for a biofireplace is the burner. If something is done incorrectly, the consequences can be disastrous. So, here are some tips for making:

• if the fireplace is opaque, then you need to paint the narrow fuel outlet from the outside;
• a fine mesh is carefully cut to size and laid out at the top of the container. This is necessary for a more even distribution of fire and for decoration. You must watch carefully so that this mesh does not fall inside the fuel container.

Calculate the dimensions of the fireplace correctly

When designing and creating a drawing of a future fireplace, it is very important to correctly calculate its width and height

The size of the firebox depends on the area of ​​the room. There is a simple formula that will allow you to correctly perform all the calculations:

We measure the area of ​​the room and divide it by 50.

The resulting value is the size of the combustion window.

To heat a small room of 20 square meters, a fireplace with a combustion opening of 0.50 m2 is sufficient.

We also suggest using the table to correctly calculate all the necessary parameters for your future fireplace.

After calculating the width of the firebox, you need to decide on its depth. The heating efficiency of the fireplace directly depends on this parameter. According to the standard calculation formula, it is equal to 2/3 of the height of the firebox.

If you ignore this factor and, for the sake of appearance, decide to increase the depth of the firebox, this will directly affect the heat transfer of the fireplace.

Almost all the heat received from the combustion of wood will go through the pipe to the street. In this case, the fireplace will serve more of a decorative function, delighting you with the beautiful glow of the fire. You will only have time to add firewood to the firebox.

When the depth of the combustion chamber is reduced in relation to its height, there may be a risk of smoke in the room.

In addition to the correct calculation of the firebox, great attention must be paid to the arrangement of the chimney, on which fire safety and good draft depend. First of all, you need to correctly calculate the diameter of the pipe outlet and its height

First of all, you need to correctly calculate the diameter of the pipe outlet and its height.

According to SNiP standards, the diameter of the chimney must be at least 150:170 mm. If you have chosen a chimney with a rectangular cross-section, then its width should be equal to 1/10 of the size of the combustion chamber.

The height of the chimney should not be less than 5 meters. But sometimes, with high floor heights, you will need to raise the chimney even higher. In this case, we focus on the roof ridge and the pipe outlet location.

The figure shows how to correctly determine the height of the chimney.

Chimney height above roof

Therefore, carefully calculate all these parameters before you start building a fireplace with your own hands.

Required materials and tools

The main element of the design is the fuel tank; it is better to make it from a sheet of stainless steel. You can purchase it on the construction market or order it from craftsmen if you plan to construct a large structure.

If there is no need for large volumes, then you can use metal mugs by breaking off their handles. They must be installed in a fireproof tank.

The body itself can be made of almost any transparent material that can withstand high temperatures, for example, smoky special glass. The device can be installed on a coffee table instead of a smoking candle.

If you need an imitation of a real fireplace, you will have to make a decent base from the following materials:

• Plasterboard sheets;
• Self-tapping screws;
• Metal corners;
• The refractory material used to insulate the structure can be, for example, isover.

Simple tabletop biofireplace

Such fireplaces will serve as an ideal addition to any room design, and in the evening they will provide the opportunity to admire a live fire in all its glory. One of the main advantages of tabletop fireplaces is their simplicity. Let's take a closer look at how to make one of these bio-fireplaces.

To create such a fireplace with your own hands we will need:

• 4 glasses.
• A base box made of metal or other fire-resistant material.
• Glass cutter.
• Sealant for glass bonding.
• Steel mesh.
• Fireproof stones for decoration.
• Fuel container.

Step-by-step instructions for making a desktop biofireplace:

• We calculate the dimensions of the future structure. For one burner, the minimum distance between the glasses is 15 cm.
• We adjust the glass to the dimensions of the box. If they fit true to size, great. Otherwise, you need to cut off the excess with a glass cutter. The glass box after connection will be installed on the base.
• We connect the glass with sealant. To do this, apply sealant to the end of the glass and connect it at right angles to the other glass. It will take at least a day for the sealant to dry completely. To do this, stands are installed under each side.
• A glass box without a top or bottom is installed on a base. If the calculations were done correctly, then he should definitely be on the edge. To fasten the glass and the base, we again use sealant.
• We place a burner with biofuel in the center of the base and cover it with a steel mesh. It must be cut so that its edges lie on the edge of the base. It is recommended to lay the mesh in several layers so that it does not collapse under the weight of decorative stones.
• Place the stones in an even layer on the mesh. If you use natural stones collected with your own hands, they must be washed. In this case, when heated, they will not emit an unpleasant odor.
• If necessary, light the burner and check the result.

Important! This design is very easy to assemble, but has a number of disadvantages. First of all, it is impossible to replenish fuel without disassembling part of the fireplace

The second disadvantage is the lack of a combustion regulator. As a result, neither the flame intensity nor the fuel consumption can be changed.

Application area

A fireplace with such characteristics uses an open fire that arises from the combustion of environmentally friendly material, usually specially purified ethyl alcohol. If, when burning wood or coal, carbon dioxide should appear, which must certainly be removed from the house, then this does not happen with biofuel: it burns completely without compounds harmful to humans.

As we know from physics since school, to support the combustion process we need oxygen, which is taken from the living space: it becomes stuffy and difficult to breathe. A biofireplace is not endowed with all these features; it requires a minimum amount of air to maintain a flame in the burner.

A multi-level chimney system is an essential component of any heating element using natural fuel. For our device it is not needed, since smoke, as such, is simply not generated.

Area of ​​application: decorating the interiors of large and small apartments, cottages and dachas, offices and halls for receiving honored guests.

More recently, it was used for heating purposes where, for fire safety reasons, the use of other heating structures was prohibited.

But a lot of time has passed since then, and today a biofireplace is a decorative item not only for an elegant, but also for the simplest interior. And many designers boldly claim that it is perfect for almost any design.

If the floor of the room is overloaded with furniture, then a wall-mounted option can correct this mistake and provide a cozy atmosphere at home. You should not think that it cannot be used for its intended purpose - heating; although it is not so intense, it still heats the surrounding air.

There are also designs that are equipped with wheels, and this is convenient if you only need it for a while: move it to the middle of the apartment, sit on the carpet or low couch, and admire the leisurely flame. It is easy to move or remove, and, if necessary, pull out.

Biofireplace manufacturing process

Biofireplaces can easily replace an electric fireplace or fireplace stove. This accessory brings a pleasant feeling of warmth and comfort. Of course, there is the option to buy a small potbelly stove, but this is not a very cheap product. The main process of making a home biofuel fireplace will involve selecting the necessary materials.

1. The bio-stove is assembled from simple elements: a fuel tank and a frame.
2. All work begins with drawing a diagram of the desired decor item on paper.
3. When it is ready, you can evaluate your capabilities and start purchasing materials. If you find it difficult to develop a product plan, find photos of biofireplaces on the Internet and create your own version based on them.
4. Then you should take on the drawing, where you should indicate all the exact dimensions. With its help, you will never get confused and will get the desired result in the end.

How to look for clients to sell finished products

And a little about promoting finished products on the market. If you want to build a business on mediation between the manufacturer and the consumer, then you need to be well versed in marketing and working with clients. But first, you need to make a list of biofireplace manufacturers with whom you would like to work and offer them cooperation: you give them clients and sales, they give you a reward (most likely, a percentage of sales).

You can advertise biofireplaces in any way you like: brochures, leaflets, television and radio advertising, online promotion, etc. Here, as in any advertising, it is important to clearly understand who your target consumer is and competently adjust your advertising offer to their needs and desires. Since a biofireplace is a family, homely, cozy product, then when promoting this product on the market, you need to focus on these accents.

An excellent niche for selling finished goods are construction companies and designers who directly contact the client. Here it will be enough to simply present your product well to these companies, describe all its advantages and provide it with advertising booklets. This way, they will be able to recommend your product to their clients. There is a benefit in this for both you and them - you get new clients, and they always have something to offer their clients without wasting time and effort.

What is a biofireplace

The biofireplace, which is becoming fashionable, is a decorative source of open fire that runs on so-called biofuel. For safe operation, the device is framed by a portal that traps the flame inside.

Structurally, a biofireplace is a burner that runs on alcohol fuel. A mandatory element of the device is a fuel tank, which contains a sufficient supply of flammable liquid for operation.

A wick is inserted into the tank, along the fibers of which the fuel rises to the place of combustion. The combustion itself takes place in a special bowl, which can have a variety of shapes. The sizes of biofireplaces vary significantly.

Installing a bio-fireplace is a great way to decorate your interior, make it unusual and attractive. Depending on the type of device and model, the fire can be completely open or closed on several sides by the walls of the portal, transparent and opaque

In addition, some burners are equipped with nozzles. This makes the flames as similar as possible to those formed when burning wood in a fire or fireplace.

The devices are very convenient to use. First of all, they don't need a chimney. During combustion, biofuels are oxidized to carbon dioxide and water vapor. The absence of heavy impurities in the flammable liquid allows it to burn completely, without the formation of soot, soot and volatile toxic substances.

Therefore, smoke removal (which does not form) is not required. Thanks to this, the biofireplace can be installed anywhere in the room.

It does not need a heat-resistant floor frame or a separate foundation. Special permission for its installation is also not required. The only thing that needs to be taken into account when choosing a place to install a bio-fireplace is the possibility of ventilating the room or the presence of effective ventilation. This is necessary because combustion uses oxygen, the amount of which must be constantly replenished.

To ensure that the bio-fireplace does not differ from the real one, it can be decorated with firewood made from fire-resistant ceramics. They are produced in the form of whole or half-burnt logs

Biofireplaces are not only decorative, but also functional. Unlike traditional fireplaces, where most of the heat “goes” into the chimney, the devices completely transfer their heat into the room. Of course, you won’t be able to use such a device as a heating device, but it will be able to heat some area in the room. Biofireplaces are completely safe if used correctly.

The industry produces models that are most comfortable to use, equipped with electronic controls. They can be controlled from a remote control or via Wi-Fi. In the latter case, it is quite possible to integrate the device into the Smart Home system and remotely control it from a phone or tablet. It is clear that the cost of automatic biofireplaces is an order of magnitude higher than that of conventional ones.

At the same time, standard models can be considered “eternal”, since they are structurally extremely simple and there is nothing to break in them, while devices stuffed with electronics may well fail.

Composition and features of biofuel

The “bio” part of the word “biofuel” explains that only natural, renewable raw materials are used to produce this substance. Therefore, it is completely environmentally friendly and biodegradable.

The main components used to produce such fuel are grasses and grains containing large amounts of starch and sugar. Thus, corn and cane are considered the best raw materials.

You can find various brands of biofuels on sale. Preference should be given to certified products, otherwise you may face serious troubles

They produce bioethanol, or a type of alcohol. It is a colorless liquid and has no odor. If necessary, it can replace gasoline, however, the cost of such a substitute is much higher. When burned, pure bioethanol decomposes into water in the form of vapor and carbon dioxide.

In this way, it is even possible to humidify the air in the room where the bio-fireplace is installed. The substance burns with the formation of a blue “gas” flame.

This is a purely aesthetic drawback that prevents you from still enjoying the sight of an open fire. A traditional fireplace produces a yellow-orange flame, which is a kind of standard. To eliminate this drawback, additives are introduced into biofuels that change the color of the flame.

Thus, the traditional composition of a flammable liquid is as follows:

• bioethanol – about 95%;
• methyl ethyl ketone, denaturing substance – about 1%;
• distilled water - about 4%.

In addition, crystalline bitrex is added to the fuel composition. This powder has an extremely bitter taste and is intended to prevent alcohol biofuels from being consumed as alcohol. Biofuel is produced in different brands, its composition may vary somewhat, but in general does not change. It is clear that the cost of such fuel is quite high.

It is not recommended to use homemade fuel for biofireplaces, but if you still decide to try, to make it you need to use only high-purity gasoline “Galosha”

Fuel consumption depends on the number of burners and the power of the biofireplace. On average, a 2-3 hour operation of a heating unit with a power of about 4 kW per hour consumes about a liter of flammable liquid. In general, operating a biofireplace turns out to be quite expensive, so home craftsmen are trying to find a cheaper alternative to fuel. There is such an option and it is viable.

To avoid trouble, you need to purchase only high-quality components for homemade fuel. We must not forget that the bio-fireplace does not have a smoke exhaust, and all combustion products immediately enter directly into the room.

If toxic substances are present in the fuel, and this is not uncommon for low-quality alcohol-containing compounds, they will end up in the room. This threatens with the most unpleasant consequences. We recommend that you familiarize yourself with the best biofuel brands.

Therefore, it is not recommended to make fuel for a biofireplace yourself. However, if you really want to experiment, this is the safest recipe. Take pure medical alcohol. It must be purchased at a pharmacy.

To color the flame, highly purified gasoline is added to it, which is used to refill lighters (“Galoshes”).

Filling the fuel tank must be done very carefully. If liquid is spilled, you must immediately wipe it with a dry cloth, otherwise an accidental fire may occur.

Liquids are measured and mixed. Alcohol should be present in a volume of 90 to 94% of the total amount of fuel, gasoline can account for 6 to 10%. The optimal proportion is determined empirically, but you should not go beyond the recommended values. Detailed instructions for the production and use of biofuel are given here.

It is important to remember that the resulting fuel cannot be stored, since the mixture of gasoline and alcohol will separate. It should be prepared before use and shaken well for better mixing.

Disadvantages of a biofireplace

Along with its advantages, this product has its own disadvantages, which are a tribute to convenience, safety and environmental friendliness.

Dependence on one type of fuel. The burner runs only on alcohol, while a regular fireplace can be lit with any solid flammable substance.

The relative high cost of fuel. A medium-sized heating unit (burner) consumes 0.3–0.4 liters per hour. The cost of 1 liter of fuel is on average 200–250 rubles*. Burning a fireplace for one hour will cost about 100 rubles.

We are talking about factory fuel for biofireplaces.

Minimum room area. The room in which the fireplace is installed must be at least 25 square meters. m.

* TB - fuel block.

Advantages of a biofireplace

Biofireplace is a new product on the market that is rapidly gaining popularity. This is not only a tribute to fashion, but also a lot of beneficial advantages.

Convenience. The purity of combustion emissions allows the use of a biofireplace without a chimney. This decisive advantage makes it an exceptionally technological product - the fireplace can be placed in any location that meets the installation requirements. It does not require a separate foundation and heat-resistant floor lining. Approximately 50% of these products are made in a portable version, the rest are mounted on the floor, walls and even suspended from the ceiling.

Manufacturability. The alcohol burner hearth can be purchased separately, without a portal. It can then be installed into the firebox of an existing traditional fireplace. This will preserve the functions and appearance of the interior and eliminate the need to prepare solid fuel and the risk of smoke. Due to the simplicity and low cost of their design, full-fledged biofireplaces are available in a sufficient range of sizes. The portal can also be made to order from any material.

Safety. Factory-made fireplaces are supplied complete with protective panels and casings, so the biofireplace portal can be made of plasterboard or wood without fear of ignition from overheating. Ignition and combustion of fuel occurs without sparks or flame fluctuations (when using a special lighter). When burned, fuel breaks down into water vapor and CO2. The concentration of carbon dioxide is insignificant and does not affect air quality if there is standard ventilation of the premises.

Functionality. In a conventional fireplace, most of the heat is removed along with toxic waste gases through the chimney. In a biofireplace, the entire combustion temperature is transferred to the surrounding air. A medium-sized device is equivalent in power to a 3 kW electric heater.

Reliability, simplicity of the device. Basic models of alcohol fireplaces do not have mechanisms, moving parts, or wearable parts. When used correctly, these are “eternal” devices (service life is unlimited). “Biocombustion” does not form carbon deposits, which reduces maintenance of the fireplace to wiping along with other interior elements. More complex and expensive models have electronic control - from a panel, remote control or Wi-Fi from a tablet or phone. Like any electronic devices, they can fail, but not more often than others.

Originality and beauty. The new bio-fireplace can be matched to absolutely any design - from minimalist cold high-tech to luxurious baroque. The portal can be ordered in any workshop, from any material. Such an open fire in the middle of the room will become the emotional center of the entire house, intuitively reminiscent of distant ancestors relaxing at night around the fire. Always even and stable flames are a “living” piece of furniture that can be moved at your discretion.

Price. The price of the device itself, together with the portal, does not exceed the price of a fireplace of the same format with a traditional or electric layout.

Business idea: bio fireplaces for sale

Any business starts with an idea. Then a business plan is drawn up and its practical implementation follows.

If you decide to start producing biofireplaces, you should start with such aspects as:

1. Studying the legal requirements for equipment, as well as a thorough study of the manufacturing technology of devices of this kind.
2. Study of consumer demand for this type of equipment, as well as analysis of the corresponding market segment.
   This will help to find out in advance how much such equipment is in demand and how difficult it is to compete with existing manufacturers. In addition, an analysis of the most popular models will suggest the main direction of activity or an alternative path.
3. Availability of start-up capital to start production.
4. Availability or need to purchase appropriate equipment, consumables, attract qualified personnel, etc.
5. The need to coordinate the start of production activities with various regulatory authorities.
6. The degree of preparedness and compliance of existing legal documents with the chosen area of ​​activity.
   For example, if you are already registered as an individual entrepreneur, then your declared field of activity should include the production of biofireplaces, etc.
7. Determine whether, under the current conditions, a franchise is needed to successfully start production.

The production of biofireplaces is a serious production, since these devices are associated with fire, so the main requirement for a biofireplace is its safety

In general, in order to decide whether it is worthwhile to engage in the production of biofireplaces, you should get advice on all issues of interest at the centers for assistance, support and business development.

As a rule, a number of government agencies have created departments whose functions are to provide assistance to small and medium-sized businesses.

Often, the basic necessary information can be obtained from local administrations, regional bodies of Gosstandart, chambers of commerce and industry, etc.

DIY bio-fireplace made from plasterboard

The chosen location determines the shape in which the biofireplace will be made - corner or straight, along the wall. Anyone who sets out to create a fireplace at home must prepare or find a sketch with instructions on how to make a biofireplace yourself, and purchase the necessary materials:

• Drywall and profiles for it.
• Self-tapping screws.
• Materials for interior decoration, for example, ceramic tiles and heat-resistant adhesive for them.
• Exterior finishing material, such as stone.
• Cotton wool, grout and finishing putty.

We recommend reading in more detail on our website how to make a tabletop biofireplace yourself.

Drawings of finished bio-fireplaces contain information on how to make bio-fireplaces, namely, determine the dimensions. However, the design of the structure can be absolutely anything - you just need to use your imagination.

3cb4dd33d05ffdea50addfaf5977d759.jpe

When everything is ready to start working, you can begin to perform the following steps sequentially:

According to the instructions, marking lines are drawn on the wall, to which the formed guides for the body of the bio-fireplace are subsequently attached. Using self-tapping screws, rack profiles and frames are installed.

Using a plumb line, you need to check the correct location of all elements

Next, during the construction of a biofireplace, the frame is covered with plasterboard. The optimal distance at which it should be fastened is from 10 to 15 cm. When performing this work, you also need to lay a layer of mineral wool about 5 cm thick in the firebox area.

The direction of the fibers - vertical or random - of mineral wool affects the properties that it best provides. Thus, for bio-fireplaces, a material with a chaotic direction is suitable, which better provides thermal insulation properties.

A recess is left at the bottom of the firebox, into which the burner will be installed in the future. Then, using non-combustible materials, the bottom of the bio-fireplace is formed. On the outside, the drywall is puttied and lined with the selected material.

For cladding, a material more suitable for the interior and price parameters is selected. The main thing is that it is fireproof.

The remaining seams are rubbed down, the surface is wiped with a damp and dry cloth. After this, when building a bio-fireplace with your own hands, you can start decorating - add a burner, lay out decorative elements. You can also take additional protective measures, such as installing fire-resistant glass on the front wall.

The burner allows you to reproduce the fire evenly, with a bright color, without flashes. Some burner models contain protection against fuel spillage when tipped over.

Portal creation technology

The sequence of work consists of stages:

• Frame installation.
• Covering the frame with plasterboard.
• Covered with fire-resistant material.
• Installation of bio-fireplace.
• Decor.

Creating a frame for a homemade bio-fireplace for an apartment begins with installing profiles with dowels, screws and self-tapping screws. Instead of profiles, the use of corners is allowed.

How a biofireplace works: consideration of the design and principle of operation

The details of the future frame are carefully measured at the construction level, then connected into a single structure using a screwdriver and drill. Drywall sheets are measured to the required size and mounted on the frame.

After installing the drywall, putty is used to seal the seams. Wait until it dries completely.

The video shows an example of a homemade desktop biofireplace

Special tiles for lining the inside of the biofireplace must be made of fire-resistant material. Any hard, non-flammable material will be suitable for these purposes. Then the heating element is installed.

TIP: The heating element is a burner, which should be located at the base of the fuel part. This would be a great design solution.

The final stage is the external finishing of the biofireplace with artificial stone or ceramic tiles.

To simulate a fireplace, a portal for a bio-fireplace made of plasterboard is used. If desired, it can be mounted on the wall

Step-by-step assembly instructions in detail

There are a lot of ways to make a fireplace for apartments. For example, there are step-by-step instructions for assembling a decorative stove that will fit perfectly into any home.

To create it you will need the following parts:

• fuel block with a valve, a stand for it (made of metal);
• fire-resistant ceramic glass for both walls;
• bolts, washers and pads;
• rubber gaskets and metal legs;
• black paint that protects from fire, or a special material used for the panel design (stone, aluminum).

Regular assembly:

First of all, make a part for the tank.

• According to the drawings, make 2 beams. They will act as fastening for the plywood part. You only need to cut out the top and bottom halves. A glass frame will be attached to the bottom.
• Make a rectangular hole at the top for the fuel container.
• Drill holes for the bolts. Bolts that have silicone gaskets will pass through them. All actions must be carried out carefully so that the structure does not break.
• When the structure is ready, a fuel container is installed in its upper half (in the cut hole).

Sketch and drawing

Of course, you need to start work with a sketch of the future work. It is first sketched out in pencil to clearly see what you would like to see in your home. When the sketch is made, you can clearly assess your capabilities and strengths.

Next, you should make a detailed drawing of the future fireplace with all dimensions. This plan will be easy to navigate when making all the parts and during final assembly. Roughly, the diagram might look like this.

Materials

The main element for a fireplace is the fuel block. What shape it will be depends on the chosen design of the biofireplace. This can be a hermetically sealed box made of stainless metal, which has a narrow slot for the flame to exit and refuel the fireplace with biofuel. The metal for its manufacture must be chosen with a thickness of at least two millimeters. This container can be purchased ready-made or made to order.

One of the main elements is the fuel block

If you have been dreaming of a small desktop accessory, then a small mug with a stainless steel mesh would be quite suitable for the fuel tank. The mesh acts as a divider and barrier to open fuel; it is easy to add flammable liquid through it and light a fire.

The mug is also suitable for a larger fireplace, if you install several of them and create not one, but two or three separate torches in one composition. If there is a handle on the mug, it must be carefully removed (cut off) without damaging the surface of the container, since it will contain fuel and should not have any extraneous holes.

The fuel block can be made even from an ordinary mug

The fuel block must be installed in a larger container, also made of metal.

Equally important in the manufacture of a fireplace will be its decorative design - after all, you want it to look aesthetically pleasing and decorate the room with its appearance, and perhaps even become its central accessory.

To make the frame, you will need to find a fire-resistant material. Most often, fireproof glass is chosen, which will protect the fire, withstand high temperatures, and at the same time allow you to enjoy the beauty of the flames. On the panel around the fire, multi-colored or plain stones, neatly laid out and glued or poured randomly, will look great.

Sea pebbles are an excellent decor for a fireplace

A biofireplace is usually placed on a cabinet, a small table or a special decorative stand.

Types of biofireplaces

Depending on the dimensions of the structure and the location of its installation, there are several types of biofireplaces.

There are several types of biofireplaces

Floor-standing

The advantage of such a fireplace is its mobility

Massive and solid structures that can be installed next to a wall or anywhere in the room. The design solutions of the case are very different. There are eco-fireplaces made in the shape of a tree trunk, forged, decorated with carved metal sheets, decorated with colored glass inserts.

a53da261ccb611fe793540376b572e56.jpe

Ceramic firewood is purchased for floor-standing devices; outwardly it is almost indistinguishable from the real thing. Imitations of coniferous and deciduous trees are possible. These accessories bring the appearance of the bio-fireplace as close as possible to the natural one. The burner is decorated with chipped or rounded stones. They are necessary to create the effect of a more “living”, natural flame.

Wall-mounted (mounted)

A hanging biofireplace can be placed at any height

Wall-mounted biofireplaces are lightweight and light-weight devices, equipped with protective fire-resistant and transparent screens on 1, 2 or 3 sides. All models are flat, equipped with a back wall made of heat-resistant material. The advantages of this type of biofireplaces include:

• a light weight;
• Possibility of installation at any height;
• modern style solution.

To prevent the possibility of falling, the hanging devices are securely fastened to the walls.

Tabletop

A tabletop fireplace will become a stylish piece of furniture

Tabletop biofireplaces are miniature, eye-catching products that can decorate any interior. Most often they consist of a metal body filled with small stones. They are equipped with transparent glass around the perimeter or on both sides. The main advantage of these models is low fuel consumption. Miniature eco-fireplaces will decorate the holiday table and create a calm and peaceful atmosphere.

Built-in

Built-in biofireplaces are produced in the form of metal modules with a front protective screen.

Biofireplaces of this type can be built into walls or special niches

Installed in niches built of brick, concrete or plasterboard. There are models designed to be built into furniture. The fuel block and burner are decorated with ceramic firewood or stones.

Built-in eco-fireplaces have their advantages:

• allow you to save space and are the best choice for small apartments;
• provide modern room design;
• equipped with a height-adjustable screen.

Let's look at the working principle

The biofireplace owes its existence to devices created long ago - an ordinary alcohol burner and an oil lamp. The working principle is as follows: a component made of finely porous material - a wick - is immersed in a container with liquid fuel. Fuel, obeying the physical law of capillary rise of liquid, saturates it to the very top and evaporates through the open opening. If these vapors are set on fire, we get an even, persistent flame, as shown in the photo.

The heart of a biofireplace, made from innovative materials, is a round or elongated fuel block. It includes the following important elements (shown in the diagram below):

• a stainless steel container with a filling neck, equipped with an open opening on top - a burner;
• a damper or lid that blocks air access and is intended for extinguishing a fireplace;
• fireproof ceramic filler with a large number of very small pores;
• the side system does not allow fuel to splash out;
• Small portable structures are equipped with fire protection if they tip over.

In much inexpensive variations, non-flammable fiber can be used instead of ceramics

Reference. The price of cheap models available for sale starts from 80 USD. e. A large share of this cost is due to the stainless combustion chamber housing and ceramic filler.

Corner version of a wall biofireplace

According to the design method, eco-fireplaces are divided into the following types:

1. Tabletop. They stand out for their small size and mobility, but require care during use. The product must not be installed or lit under flammable interior objects (for example, shelves).
2. Floor models are equipped with both a point and an oblong burner. They can be carried, but installed only on the floor.
3. Wall options have a quadrangular shape and can be equipped with several burners.
4. Built-in type. Designed for installation in a niche or in the middle of a finished fireplace portal.
