Diesel stove for the garage - choosing and making it yourself

Diesel heaters are most often found on AliExpress. Thanks to their design, they take up little space in the cabin and consume minimal battery power. Before purchasing, it is important to pay attention to the characteristics of the product. First of all, this is the voltage of the power supply. For passenger cars, 12V devices are suitable, for trucks - 24V. Of course, the kit should contain all the necessary accessories to connect the heater: hoses, clamps, fasteners, filters, etc.

Those who really want to save money should carefully study not only the prices on AliExpress, but also the fuel consumption of a particular model. This figure rarely exceeds 0.5 l/h. Important technical characteristics also include the operating temperature range and power of the device. Dimensions and weight matter if the autonomous heater is planned to be installed in the interior of a small car. Additional features like an LCD display, auxiliary sensors and remote control are not needed by all buyers, so there is no need to overpay for them.

Advantages and disadvantages

Any option for creating or purchasing a stove to maintain the desired temperature in the garage has both positive and negative sides. There is no need to stop at the first option that comes to you.

Only by examining and analyzing them, as well as taking into account all the positive and negative aspects, can you finally decide on the choice in each specific situation.

The positive points are:

• Low cost of the fuel used and its low consumption compared to wood or coal.
• Low amount of harmful emissions into the room and atmospheric air. But it is worth remembering about safety; any process of burning hydrocarbons is accompanied by the release of a life-threatening, insidious and invisible gas - carbon monoxide, which has no odor. Therefore, issues of room ventilation should be treated with great responsibility.
• Availability and low cost of materials for the construction of such a furnace; all you need is a little metal.
• The ease of manufacturing such a stove; even a person who is far from the intricacies of metalworking can cope with such work. All you need is to be able to use a grinder and a welding machine.
• Possibility of reliable operation in cold and warm seasons.
• Small dimensions of the heating unit.

There are fewer negative aspects, but they also exist:

• The stove emits the smell of burnt petroleum products, and the effect of carbon monoxide on the human body was described above.
• The heating device needs to be cleaned regularly, at least once a week.
• If a diesel stove is not properly maintained, it often fails.
• Electrical heating appliances and other hot surfaces should not be used near such a stove.

Why are interior heaters needed?

Starting and heating a car in cold weather is a big problem. Especially in the morning, when you have to rush to work. To speed up the process, interior heaters were developed.

These devices turn on simultaneously with the engine and manage to heat the car before turning on the stationary stove, which usually needs at least half an hour to reach the desired temperature.

Important! Some car owners consider an additional heater overkill. But they do not take into account one important point - a conventional stove is turned on manually and the driver has to sit in a cold cabin. With a heater, such discomfort is eliminated: while the engine is warming up, the interior also heats up, so even in cold weather it will be pleasant to get into it.

Varieties

Based on the manufacturing method, a distinction is made between factory-made and home-made stoves. Ready-made stoves will cost more, but the buyer of such a unit will save time and money on independently manufacturing such a device. A diesel fuel stove for a garage is one thing that you shouldn’t skimp on, because... it pays for itself very quickly, you just need to take proper care of it.

According to the heating method, all diesel stoves can be divided into models with direct heating, as well as stoves with indirect heating. Direct heating devices do not have a system for removing exhaust gases, so they are not suitable for small rooms; the concentration of CO in the garage will be increased, which can lead to carbon monoxide poisoning. Indirect heating devices are in great demand because of their safety; they are somewhat more complex and consist of:

1. Fuel tank (powered by diesel fuel).
2. Combustion chambers.
3. Nozzles and adjustment screws.
4. Main building.

The principle of their operation is similar to a diesel engine of a tractor or bulldozer; fuel flows from the tank through a nozzle into the chamber where diesel combustion occurs. Next, through the heat exchanger and nozzle, the heated air exits into the heated space.

Based on the type of fuel used, there are stoves that run only on diesel fuel, fuel oil or waste engine oil. There are also universal stoves (most often homemade) that can operate on any of the listed types of fuel.

Popular manufacturers of car heaters

Autonomous heaters (stoves) for cars are produced by many companies. But not all brands can boast of reliability. The best brands are listed below:

1. Webasto . The German company is widely known for the quality of its products. It has been on the market for more than a century and traditionally surprises consumers with innovative technologies.
2. Eberspacher . A small family brand from Germany, over more than 150 years of existence, has managed to grow into a serious brand with representative offices in different countries.
3. Belief. A well-known company that produces various types of equipment. It is characterized by reliability and an innovative approach to product line development.
4. Planar . The Russian brand, whose factories are located in Samara, produces affordable and high-quality products adapted to Russian realities.

Which diesel stove to choose?

When choosing a stove for a garage that is powered by diesel fuel, you should take into account a number of characteristics, such as the power of the stove, the material of manufacture, the possibility of use at different times of the year, the price factor, etc.

Criteria

Power

An important parameter, because the more powerful the stove, the larger the area of ​​the room it can quickly and efficiently heat. On average, for heating 10 square meters. meters of room you need to spend 1 kW of energy.

Based on these data, and knowing the area of ​​your garage, you can calculate what power stove you need to purchase or manufacture.

Material of manufacture

Such devices are made mainly of steel - metal sheets and corners using welded joints. There are also homemade drip-type stoves, which are made from pipes or old gas cylinders.

The lower hemisphere of such a cylinder is used as a bowl where combustion occurs, and the fuel tank is placed outside the body; diesel fuel is dosed to the source of the flame through a metal tube, which eliminates spontaneous combustion.

Price factor

Prices for diesel stoves for garages are quite low, as well as for diesel fuel or fuel oil, and every car enthusiast has used oil on hand. From an economic point of view, such a heating device would be the best option.

Prices for stoves using diesel fuel start from 3,000 rubles. Diesel furnaces that run on fuel oil or waste oil are slightly more expensive.

Other points

• An important point is that the stove has an inspection window (plug). This allows you to control the combustion process and increase or decrease the supply of air mixture to the compartment where fuel combustion occurs.
• According to their dimensions and installation method, diesel stoves can be either large stationary or small portable. The choice here is huge and everyone can choose a unit based on their specific needs, goals and objectives.

Popular models

1. Multeat Eco 18. The model runs on used engine oil. Its cost is 21,500 rubles. The stove does not include a fuel tank; any tank with a tap and a fuel filter can be used as one. There is a system for controlling the supply of fuel to the combustion plate.
2. Solar gas PO-2.5 Compact and inexpensive stove running on diesel fuel. It will cost the buyer only 3,300 rubles and is capable of heating a room of up to 25 square meters. meters, its power is 2.5 kW. It is very popular among hikers, summer residents and owners of small garages.
3. Ritsa. A budget option for an oil-fired furnace. With the ability to heat an area of ​​up to 150 sq. meters, its price will be only 7,000 rubles. There is a chimney and a 10 liter fuel tank.

Making a diesel stove with your own hands

Most of the diesel stoves in garages of car enthusiasts are not purchased, but homemade. Below is an example of a drawing of two drip-type stoves operating on diesel fuel; the first version is made from a gas cylinder and is intended for heating liquid in a closed circuit, and the second, made from a piece of pipe, is for air heating of the room.

Drawings of a diesel stove for a garage

Description of structural elements

What will be needed for production?

The main materials will be steel sheets, angles, pipes for the air duct, fasteners (bolts), a cylinder or a piece of pipe - it all depends on the imagination and capabilities of the designer. The tools you will need are:

• Welding machine.
• Bulgarian.
• Spanners.
• Measuring and marking tool.

Main stages of manufacturing

1. The first step is to make four legs from the corners, their length is 25 - 30 cm.
2. By welding, attach them to the lower compartment of the future structure.
3. Make two holes for pipes in the lower and upper parts of the stove; the diameter of the lower one should be smaller than that of the upper outlet.
4. Weld the lower pipeline, as well as a small piece of the upper pipe under the air duct. It should be removable and make it possible to conveniently clean the furnace boiler.
5. Install the lower and upper parts of the stove, as well as the pipe for the burner. The flame will burn in the lower compartment, fuel will be supplied through the tube, and the upper part will act as a radiator.
6. 10 - 12 holes need to be made in the fuel pipe at a distance of 5 cm between them, the first and last holes should be located no closer than 10 cm from the body of the diesel stove.
7. Make a round window with a diameter of 15 cm in the fuel compartment and attach a plug to it using bolts. With its help, during the combustion of hydrocarbons, you can regulate the oxygen supply and draft.
8. Install the chimney on the top of the stove and take it outside the room.

Another implementation option

In the video you can see various implementations of diesel fuel stoves:

Price

The most expensive device presented in the rating is the Webasto Air Tor 3500, a 12-volt autonomous diesel cabin heater. Russian Planar 4D complete with tubes, boiler and other necessary elements can be purchased at half the price.

What else to look for when choosing

The dimensions of the car directly affect the power of the purchased Webasta. It is also important to take into account the level of thermal insulation and the natural climate.

Below are approximate recommendations for selection, depending on the type of car:

• 2 kW - cars and trucks without a sleeping bag, with a low cab;
• 3 kW - minibuses with up to 12 seats;
• 4 kW - trucks with a high cab and a sleeping bag;
• 4.5 kW - minibuses with more than 12 seats;
• 5 kW - shift buses.

And depending on the make/model of the car:

• 2 kW - Volvo FH FL, MAN, Mercedes-Benz Atego, UAZ “Tabletka”;
• 3 kW Mercedes-Benz Actros;
• 4 kW - Renault HIGH SLEEPER CAB;
• 5 kW - Toyota Coaster.

Often, many motorists make the mistake of trying to purchase a device with more power than necessary. This is unfounded and even harmful, since in small cabins “autonomy” with very high power will eventually lead to repairs and high consumption of electricity (fuel).

Thus, an autonomous heater must be selected depending on the internal equipment of the car and the expected heating area.

Terms of use

If they are not followed, autonomous stoves will fail ahead of time in severe frosts and other unpredictable situations. To avoid costly repairs, you must turn on, operate and turn off the devices according to the instructions.

1. Before initial start-up, perform diagnostics. Turn on the ignition only if there are no fault codes 002, 052 or 001 (as well as others) on the remote control.
2. During operation, the heater may overheat. Then it will be automatically blocked. If the device does not have any malfunctions, the fan will turn on. It will purge the combustion chamber, freeing it from fuel vapors. Then you can start the stove again.
3. Turning off the autonomous heater is also not so easy. First, the fuel pump stops, then the torch goes out, cleaning starts, and the heat exchanger cools.
4. In winter, the intake air pipe may become clogged with snow dust. Because of this, the combustible mixture becomes over-enriched and a lot of smoke appears. As a rule, there is nothing dangerous about this. But if the fan constantly makes squeaks, you should urgently show the device to a specialist. This is a clear sign of bearing failure.
5. The control unit located under the fan may fail. In this case, it will not produce the correct rotation speed, and again a lot of smoke will be produced. In the worst case, the unit will explode due to a short circuit. As a rule, this happens due to the fault of the driver himself. For example, when it does not turn off the “autonomy” while transferring current to another battery - “lighting up”.

And of course, when operating gas Webasts, it is important to prevent liquid gas from escaping. Also, you should not allow the heater to operate at the highest possible speed, as this will excessively heat the air in the cabin and may cause you to feel unwell.
