Homemade diesel stove for garage heating: analysis of 3 designs

Advantages of diesel heat generators

- The installation of a light fuel heating device is the lowest among other options. Installing a gas boiler, taking into account the chimney equipment, obtaining permits from firefighters, a sanitation station, an architectural organization, will cost you much more. An electric boiler is also distinguished by its low cost and ease of installation, but the cost of its energy carrier - electricity - is extremely high. In addition, not every electric line is able to withstand such a high load.

- If the room in which the light fuel boiler is installed does not come into contact with living rooms, then the chimney can not be equipped.In this case, a hole is made in the wall, into which a sandwich is inserted - a piece of a chimney pipe in such a way that the wall does not catch fire. No other devices required. The burner turbine pushes the air out on its own.

- Working in automatic mode, the boiler itself maintains the required temperature of the water in the heating system. The burner automatically turns off when the desired temperature in the system is reached and turns on when the coolant cools down below the set thermal level. The burner is equipped with a whole system of safety devices that ensure its safe and reliable operation.

- If the system is properly organized, then diesel-fueled heaters will provide an almost ideal temperature regime in the room.

— Light heating oil is used as an energy carrier, which costs approximately 30% less than automobile diesel fuel.

Disadvantages of heating on diesel fuel

- Despite the automation of the system, it requires the presence of a person. The boiler can be left unattended during the working day, but it must not be left to function independently, for example, for a week. The reason for this is the poor quality of the fuel, which can lead to the shutdown of the boiler. In winter, this can lead to the destruction of the heating system as a whole. This problem can be solved using the SMS notification system. This will allow you to be aware of the status of your heating system.

— The burner and boiler require constant maintenance.

- With low-quality fuel, various impurities may be present in it, which can lead to nozzle clogging and pump failure. This problem can be solved with a filter.It is more difficult to deal with paraffins and other substances that have a high viscosity.

- High noise level during operation.

— The burner is a volatile device that requires an uninterruptible device.

Be careful when buying fuel. If your reserve tank is outside and not insulated, then you need to purchase winter fuel, and if the barrel is thermally insulated, then summer fuel can be used.

When choosing fuel for heating your home, you need to weigh the pros and cons and choose the most affordable and efficient option.

Homemade garage heater

The main condition for the high-quality assembly of the heater with your own hands is to follow the sequence of work and safety measures. The most popular scheme is a flameless combustion heater, the principle of operation of which is based on the fact that gasoline / alcohol vapors are oxidized by oxygen using a catalyst. Thanks to this principle of operation, thermal energy is produced by a chemical reaction, and not as a result of fuel combustion. Therefore, the heater does not burn out oxygen and maintains a healthy microclimate in the room. Work order:

1. Pick up a fuel tank with a stopper and a neck (you can use an old car fuel tank).
2. Assemble the heating element. First you need to prepare a gasket of asbestos wool and impregnate it with a catalyst, then equip it with two iron grids with a frame (heating element).
3. Place the heating element in the burner. When laying, it is recommended to install a wire gasket between the installation site and the frame and wrap it with corded asbestos.
4. Make a wick through which gasoline will be supplied to the burner using asbestos wool or cloth.
5. Install the wick: lay the lower part on the bottom of the tank, place the upper part evenly under the net.
6. Fill with cotton wool all the free space in the tank.
7. Equip a homemade heater with a metal cover. The cover must be put on the burner and stop the appliance.
8. Pour gasoline (100 ml) onto the grid of the heating element and set it on fire. When the fire goes out, the suction of vapors from the tank to the heated surface will begin. The vapors will begin to oxidize, raising the temperature in the room.

For the manufacture of the heating element, it is recommended to use long-fiber asbestos: impregnate the material with a cobalt-chromium catalyst and leave for 1 hour. The catalyst can be made independently from manganese, cobalt, concentrated ammonia and ammonium dichromate. Cobalt chromate, which will settle on asbestos during impregnation, must be dried at a high temperature (+120 °), then loosened and calcined for three hours at t ° +400. After that, the mass must be evenly laid between the grids. The main condition for the operation of such a heater is to protect the unit from water, oil or dirt.

Efficient space heating can be done in another proven way - with the help of a do-it-yourself electric garage heater. The heater can be assembled practically at no cost from old spare parts: a pump with nozzles, an electric motor with a torque of 1,500 rpm, a radiator and a fan. Work order:

1. Weld a frame from a metal corner.
2. Mount the motor with starter, radiator and pump on the frame.
3. Install 3 heating elements with a power of 1 kW or triple with a common shank in the lower tank. First you need to cut a hole in the radiator tank, solder the threaded ring to the edge, then install the heating element.
4. Install the car V-belt and adjust the tension by moving the pump towards the frame. Installing a car belt will ensure the rotation of the electric motor to the pump.
5. Additional equipment of the heater - connect the electric motor through a sensor (DTKB or similar). The sensor will ensure that the desired temperature level in the room is maintained.

Feature of the heater - the heating element is placed in liquid and when heated does not come into contact with air, so it does not burn out the air in the room. It is recommended to use automotive antifreeze or transformer oil in the heater. The advantage of a homemade device is that the motorist will be able to regulate the temperature by changing the air flow that passes through the tank. To achieve the greatest efficiency of the heater, it is necessary to install an expansion tank and select the diameters of the pulleys so that the liquid is heated to 80 °.

Step-by-step instructions for making an oven

Step 1. In our example, a simple 250-liter barrel with thick walls is used - ideal for making an oven. Cut off the top of the barrel, but don't throw it away.

The top of the barrel is cut off

Step 2. Make a kind of cover from the top - a "pancake" for supplying oxygen. Adjust it to the size of the barrel - as a result, when installed, 2 mm should remain between it and the walls around the entire circumference. Seal the neck of the lid.In its center, make a hole for installing a pipe through which air will be supplied. Also weld 4 channels, as in the photo below.

"Pancake" for air supplyAnother photo of the element

Step 3. Stepping back a little from the top edge, cut another hole in the wall of the barrel - for chimney installation. In our example, a pipe with a diameter of 140 mm will serve as a chimney.

Step 4. Start making the lid. Make it out of sheet metal thickness 4 mm, and from below weld a sealing ring corresponding to the diameter of the barrel. In the center of the cover, make a hole for the pipe that was welded to the "pancake".

Oven lidIn the middle of the lid - air duct hole from "pancake"

Step 5 At the bottom of the barrel make simple legs so that the structure is stable. The legs must be metal, as well as all other elements.

Step 6 Install the stove in the right place and start creating the chimney. In our example, it is of a prefabricated type. First of all, make a clamp, through which the chimney will be attached to the body.

A clamp that will allow you to attach the chimney to the stove

Step 7. Make guides in the chimney, thanks to which it will be easily fixed to the body.

Step 8. Dock the barrel with the pipe, without fail laying all the joints with asbestos cloth. Put a collar over the fabric, tighten it.

Step 9. That's it, the design is assembled, you can check its performance. Load sawdust or firewood inside.

Step 10Pour the used oil into the fuel, then install the cap. As for the "pancake", then do not use it yet. After the fuel flares up, remove the lid and put the "pancake". For a full warm-up of such a design, it takes about 10 minutes, in the future, firewood will burn for a long time. Although how long the burning will last depends largely on the quality of the fuel.

If you wish, you can modify the design described above, although it will already do its job perfectly. For example, to increase efficiency, you can increase the surface and thereby improve heat transfer. To this end, weld metal plates on the sides of the case.

In addition, you can make a grate with an ash pan: cut a circle from a sheet of metal along the inner diameter of the body, drill holes with a diameter of 60-80 cm and install from below. After that, the ash will fall down through the holes - to where the ash pan is equipped. It is believed that the fuel because of this will burn faster, remember this moment and make sure that the ash pan is sealed as much as possible.

Heating with droppers

If a drip oven is used for heating, its power is needed at least 15-16 kW. This cannot be achieved only by increasing the frequency of the drops: due to the increased heat release, the drops will evaporate even in the supply tube. Stove (now homemade boiler liquid fuel) will switch to burning with pops, and then go out. Therefore, in the heating boiler on diesel fuel and mining the dropper tube is brought to a flame bowl in a shirt, cooled by an air stream.

But that's not all.Due to the same greater heat release, the evaporation of fuel and the combustion of vapors will be more intense. Part of the fuel vapor will be immediately thrown aside, will not burn and will accumulate in the volume of the boiler, which can lead to an explosion. Therefore, a swirler is installed at the outlet of the fuel line, and the design of the deflector will be different than in a drip potbelly stove.

System Diagram heating with drip boiler diesel fuel

Air supply up to approx. 12 kW thermoconvection non-volatile: the intake air is first heated in the air jacket of the chimney, and then cools somewhat in the aluminum corrugated hose, which provides the necessary "suction". For high power, airflow from a fan is required approx. 60 W, for example, blowing the VAZ-2109 radiator.

A significant drawback of the described system is that in order to avoid the burner going out and the accumulation of explosive vapors in it, the water in the boiler jacket must flow countercurrent to the natural thermosiphon circulation, i.e. top down. Therefore, in the system circulation pump required with non-volatile (thermomechanical) automatic emergency shutdown of the boiler in case of power failure. All this makes this system very complex and at the same time unreliable.

It is possible to build a drip boiler for a water heating system with natural thermosiphon circulation, but in this case its design becomes more complicated and it becomes necessary to force air into the fuel line cooling jacket. If you want to be heated without fail with diesel fuel or there is simply nothing more, then see the drawings of a drip heating boiler with natural circulation of the coolant in a water jacket.on the trail. rice.

It is also an option

There is another way to start a wood-coal stove on kerosene and diesel fuel: put an ejection burner into the furnace. It is possible if there is a source of compressed air - a boost of 1.5-2 ati is needed. Provided that the fuel tank is located below the burner (this is absolutely necessary!) This method is as safe as possible: there is no pressurization - the burner goes out. The assembly drawing of the spray head of the ejection burner for gasoline, kerosene and diesel fuel is given in fig. Air is supplied to the annular gap (highlighted in color); the missing dimensions can be taken proportionally, because scale drawing.

Design features and principle of operation

Diesel stoves for the home or garage have great merit, especially in the conditions of the domestic winter. Since their main advantage is the rapid heating of the air, even in an unheated room.

Solar heating boilers

Today, consumers are offered heating boilers running on diesel fuel, which, according to the scheme of operation, are completely similar to turbocharged gas appliances. That is, the air blown by the inflatable fan is mixed with solar oil and thus forms a fuel-air mixture. After that, it enters the furnace and, together with the oxidizer, is ignited by the electronic ignition system. In the process of combustion, the solarium gives off its energy to the heat exchanger, through which the coolant passes.

With traditional gas boilers, which are used as a heater for residential premises, solar-powered appliances are also similar in that they are easily controlled electronically in automatic mode. Fan speed, the process of fuel supply and ignition can be controlled by a specially programmed thermostat that maintains the required temperature in the house.

Solar stoves

Today, consumers can purchase compact solar-powered heaters. They are called potbelly stoves equipped with fans.

They can be represented by two varieties:

• Direct heating - the appliances do not have a chimney, which makes them inconvenient for heating a garage or other small space.
• Indirect heating are convenient devices that have gained popularity among garage owners. The design of the fuel tank and the combustion chamber works according to a fairly simple principle - through the nozzle of the fuel tank, the liquid enters the chamber, where it then burns out using the air supplied by the fan. After passing through the heat exchanger, air flows are directed through the nozzle into the room, warming it up evenly and quickly.

The design of the potbelly stove includes:

• Removable fuel tank equipped with a valve.
• Adjusting screw.
• Replaceable block with wick.
• Frame.
• Lattice.
• Burner.
• Reflector.

Liquid fuel heater As a rule, a modern diesel fuel stove is equipped with a special flame control system that automatically turns off an overheated device. Such mobile devices are ideal for heating various rooms:

• Cabins, garages, construction sites or security posts.
• Trade objects.
• Country houses and other small residential premises.

Mobile potbelly stoves will become indispensable when it is necessary to heat a room that is in an emergency condition, as well as during a hike to organize heating in a tent when there is no desire to make a fire. The choice of such a furnace will be the best solution for creating the necessary microclimate. Such a device can serve as an additional source of heating or as a main heater, which can also be used to heat food.

Operation features

Before you light the stove on diesel fuel, you need to install a tank in the right place, and also pour fuel into it. The next step is to remove the grate with the burner and install it in the wick unit. After that, the burner and grate are reinstalled, the adjusting screw is opened and after 30 seconds the burner can be ignited. After intensive burning begins, you will need to turn the adjusting screw all the way and wait a little for the flame to settle. Then open back, setting the desired degree of heating.

Switching off the device is carried out by screwing the screw until it stops. In this case, you need to make sure that the diesel fuel burns out to the end and the fire goes out completely.

Advantages of using solar boilers

Affordable cost is one of the main advantages of solar-powered devices. The price of appliances for a private house is 30-100 thousand rubles. There are dozens of device models on the market.

The pluses also include:

• autonomy of the device;
• safety of use;
• high efficiency;
• fuel availability.

Autonomy of the device

The device requires electricity to operate.If there is no connection to the network, the safety and control automation is powered by an electric generator, so the boiler is considered an autonomous heater.

All boilers of this type have automatic control of operating modes. The water in the heat exchangers is heated to a predetermined temperature, the burner is switched on and off automatically.

Safety of use

The device is not dangerous during operation. Automation stops burning fuel if there is a power outage or short circuit electrical appliances.

Diesel fuel is a relatively safe fuel (compared to natural gas or gasoline).

When used correctly, an explosion or fire of the device is excluded.

The installation of the boiler does not require permission from the supervisory authorities. The homeowner must comply only with the requirements for the room in which the boiler is installed and for the chimney.

High efficiency

When diesel fuel is burned, a large amount of heat is released. The efficiency of domestic diesel fuel boilers is 75–92%.

Thanks to the heat-insulating layer under the body, almost all the heat is transferred to the heat exchangers and is used to heat the water. The efficiency of boilers of this type is slightly less than that of gas boilers.

Availability of solar oil

Diesel fuel is usually sold at gas stations, it is poured into canisters or a mobile container on a trailer.

Large quantities of solar fuel are purchased from wholesale suppliers.

Terms of delivery or self-delivery are negotiated separately.

What should be the heating in the garage

For many motorists, a garage is almost a second home. Here they delve into their hobby, take a break from the hustle and bustle and take care of the car.Therefore, first of all, you should think about the comfort of the person who is in the room for hours.

For the car, heating is also necessary, because. low temperatures adversely affect its technical condition and significantly reduce the service life.

When it gets cold, the garage gets too humid. Condensation forms on metal parts, which provokes corrosion processes. In a cold room, the car body quickly rusts and becomes unusable.

To keep the garage dry, you should take care of good waterproofing and ensure the normal operation of the ventilation system. However, moisture still gets into the room on the wheels of the car. It evaporates and drops of water settle on surfaces. If there is no heating, moisture accumulates, which causes fungus, mold, and rust to appear. To prevent this from happening, heating is necessary.

Low temperatures cause the oil to thicken and reduce battery capacity. Because of this, there are difficulties with starting the engine, and fuel consumption increases. Therefore, it makes sense to spend time and effort on assembling a miracle stove.

Features of the operation of the garage determine the requirements that apply to heating systems:

• Efficiency. The oven must quickly warm up the air and maintain the desired temperature for several hours.
• Ease of operation. Coming to the garage, its owner should spend a minimum of time and effort on heating the room.
• Ease of maintenance. The furnace needs to be inspected, cleaned, repaired in a timely manner, so its design should be simple and understandable, and parts should be easily replaceable.
• Availability of an energy source.When choosing a heating system, the availability of fuel is of fundamental importance. For a garage, a diesel, diesel or waste oil stove is well suited.
• Safety. There is always a certain amount of combustibles in the garage. Since these rooms often serve as workshops and sheds, flammable materials are often found here. Therefore, heating must comply with all fire safety standards.
• Cheapness. The cost of maintaining a car and arranging a garage is already high, so saving on heating without compromising its quality is an urgent issue.

When choosing a suitable heater, you should prioritize, because. the ideal is unattainable. The easiest to use are electric heaters. This source of energy is available in almost any locality. However, the price of heating with electricity is too high, so it is worth considering other options.

This method of heating is chosen by people who are ready to invest in an infrared heater and pay electricity bills. Although the devices are very economical, they are still not cheap. The main advantage of infrared heating: objects are heated, not air (it warms up indirectly, in contact with warm surfaces). This allows you to create local thermal zones.

Garage owners, who have the opportunity to buy solid fuel inexpensively, make good old potbelly stoves. Such heating is reliable, and its effectiveness has been proven by time. There are also disadvantages: you will have to install a chimney, and keep a supply of fuel in the garage, which takes up a lot of space

To heat garages, workshops, utility rooms, heat guns are often bought. There are many models that run on gas cylinders, electricity or diesel fuel. Every garage owner is sure to find a suitable option. The only negative is the high price of the device

Models of industrial production are compact, beautiful, easy to use, but not cheap. If you make a miracle stove yourself, you get a completely functional and inexpensive design. The only negative: in terms of design, it will not be able to compete with aesthetic industrial models.

Furnace Specifications

This unit is small in size and light in weight. It has a fairly simple design. An open tank and a fuel tank are installed in the steel case, which are interconnected as communicating vessels.

To limit the flow of combustible substance from the tank the outlet is equipped with a special valve. From the kerosene gas of the furnace got a burner, powered by diesel fuel. This element is a reliable wick, in which the lower part is immersed in a fuel tank.

After opening the valve, fuel will begin to flow into the working container. A special cord, pre-wound on the base in the form of a cylinder, quickly absorbs it. After a few minutes, the oven can be ignited. No tools are required for this, because everything is done by hand.

In order for the device on diesel fuel to warm up to the desired temperature, you will have to wait a little. The power of the unit is regulated by a valve. He is also her switch.

The downside of the device can be called the attenuation of the burner 10 minutes after the end of the diesel fuel. In order to somehow compensate for this drawback, many manufacturers install a metal grate directly above the burner, which, if necessary, will allow heating water in a container.

One of these miracle furnaces is the Solarogaz PO-1.8 model, made in Russia. The maximum power of such a unit does not exceed 1.8 kW. In the photo below you can see this device.

Conclusion

Diesel stoves are an excellent and inexpensive option for quickly heating indoor air in garages. With their small dimensions, they perfectly cope with their task and give the desired air temperature in the shortest possible time.

Thanks to their mobility and compactness, they can be used at any time of the year. In addition, factory-made diesel mini-stoves are used even by tourists on hikes. to heat their tents. In the summer, it can be quite cool in the garage, especially at night, so heating with the help of such a unit will help out a lot.

However, they require careful care and mandatory compliance with safety regulations when working with them.

Be sure to remember that carbon monoxide is a dangerous and invisible killer, so ventilation and sealing of welds when using such devices should be given increased attention.
