Used oil is a proven fuel that can be used to heat small spaces. Recently it has become less profitable, but it is suitable for small warehouses, garages or utility blocks where fuel consumption is low.
An oil stove is an inexpensive way to heat the average garage. The material for the firebox is not difficult to find, and you can assemble it yourself in a matter of hours. It is not difficult to assemble the unit; it is made from scrap materials.
For refueling, regular motor oil is used, which can be drained from the car. Compared to expensive diesel heating devices, there is no need to buy diesel separately.
Furnace in production: options for making the device yourself
With the approach of cold weather, many craftsmen are coming up with various designs for heating the room and heating water. First of all, the question is about the type of fuel. In search of the most rational and cheapest option, many choose to work off, the average consumption of which is about 2 liters per hour. A waste oil furnace has a number of advantages.

- wide selection of models; Manufacturers produce both small mobile heat guns used for domestic purposes and large stationary devices that are best used for heating large spaces, for example, production workshops or warehouses.
It is important to remember that heat guns must be used in ventilated rooms with an air supply system or with the possibility of constant ventilation.
Operating principle of a waste oil furnace
The prototype for oil furnaces operating on waste oil is kerogas, which was previously used in villages and dachas. It used kerosene as fuel, the vapors of which were burned in a separate chamber. To save on fuel, a waste oil burning option was developed. It can be purchased for free or at a reasonable cost at any service station.
Components of a waste oil stove.
Creating a homemade stove during mining is not a difficult process. The main task is to properly organize the system for a productive oil combustion process. To ensure complete combustion of vapors, heavy components must first be split into light ones, which is carried out as a result of pyrolysis. The oil must be properly heated for efficient evaporation.
The operating principle of an oil furnace during mining is as follows. First of all, the mining is ignited in the lower chamber of the apparatus. The combustion intensity is regulated using a throttle valve in the device body, through which air enters the chamber. Oil vapor mixed with oxygen rises upward through a vertical pipe. The pipe is connected to the upper tank, which is the afterburner chamber.
The mixture is mixed under the influence of the Coriolis force (force of inertia). The intensity of the process is achieved by choosing the correct diameter and length of the combustion chamber. To ensure complete combustion, air must flow through the damper in sufficient quantity. To do this, it is additionally sucked through holes made in a vertical perforated pipe connecting the tanks.
The combustion intensity is regulated using a throttle valve in the device body.
The gas flow is directed to the final combustion chamber, in which the upper part is expanded. During its manufacture, a horizontal separation is made between the chimney inlet and the combustion chamber outlet, which is necessary to ensure a temperature jump between the nitrogen oxide and oxygen afterburning zones. At temperatures below 600 °C, nitrogen oxides are more active than oxygen. As they decompose, they oxidize fuel particles. With increasing temperature, oxygen acts as the main oxidizing agent. Harmful substances are released into the atmosphere through the chimney.
Note! To ensure efficient oil combustion in the upper tank, the temperature must be low.
What to use instead of homemade
If you doubt your technical skills, consider purchasing a ready-made generator model that runs on diesel fuel. Despite the rather high cost of such a unit, such a purchase is quite profitable: if the required operating rules are observed, diesel heat guns can operate for ten years or more. Below are the leading manufacturers of such equipment.
Biemmedue: quality + Italian design
The Italian company, established in 1979, specializes in the production of heaters, generators, dehumidifiers and other heating equipment. The products, which include both household and industrial models, are distinguished by durability, reliability and excellent quality.
The manufacturer pays attention not only to technical characteristics, but also to design. All lines developed by Biemmedue specialists are distinguished by their compact size, mobility, and aesthetic appearance.
Master: a company with vast experience
An American company that has been producing portable heating systems, including various types of heat guns, for more than half a century. For the manufacture and design of units, only high-quality materials are used, thanks to which the company’s products are distinguished by high technical characteristics.
The diesel heat gun Master BV 110 has excellent characteristics (power 33 kW, 65-liter fuel tank, fuel consumption 2.71 per hour). Within an hour, the unit can heat 460-1000 cubic meters of air
Thanks to the innovative technologies used in the production of models, heat guns have many useful additional options, for example, a flame control function or emergency automatic shutdown in case of an unusual situation.
Kroll: innovative technologies
Heating equipment, produced by the well-known German company Kroll, is distinguished by a high level of assembly and the use of high-quality materials, primarily stainless steel. The latest engineering and scientific developments are widely used in the production of products, including diesel heat guns.
Products from other companies (Vitals, Ballu) are also popular. Products manufactured on the production lines of these transnational companies are reliable and have a long service life.
Every year you can see interesting new items in the product range: for example, the latest models of the company’s heat guns are equipped with a heat heating function, thanks to which the devices can operate successfully even at low temperatures.
Waste oil furnace: types of designs
There are several types of oil furnaces that operate on waste oil. The classic model is the pyrolysis apparatus. It is made from ready-made containers in the form of barrels, pipes, cylinders or from alloy sheets. Oil is poured into the lower vessel, which splits when there is insufficient air. In the upper tank, intensive combustion of its vapor occurs, due to which a lot of heat is released.
Temperature regulation is carried out by air supply. Such a furnace requires constant cleaning of the chambers from accumulated fractions. It does not have mechanical temperature control.
Oil is poured into the lower vessel of the stove, which breaks down when there is insufficient air.
At the oil recovery stove, a guaranteed air supply to the second chamber is realized with the help of a fan. The combustion process is more efficient, so warm air evenly enters the room.
The operating principle of a stove with a drip supply of fuel is similar to the operating mechanism of diesel engines. It is economical. However, the independent process of manufacturing the device is very labor-intensive, so it is better to purchase a factory device of this type. In addition, it should be taken into account that homemade drip stoves are picky about the quality of the oil, which must be preheated before feeding into the stove.
The most efficient model is a supercharged waste oil furnace. It, in comparison with a potbelly stove, has a higher cost. Additional heat comes from blowing fans. Supercharging can be done using a car cooler motor, and the heater is blown by a 220 V home propeller.
Standard layout of a waste oil furnace.
What guns do we repair?
They are used in cold weather; kerosene, gasoline, diesel fuel, and waste oil are used for refueling. The equipment is used in fuel and lubricants warehouses, oil depots, and automobile workshops. The machine's burner supports the combustion of engine oil, helping to utilize residual petroleum products and reduce fuel costs.
Direct heating devices
The efficiency of the equipment is 100%, since the fuel burns completely in them. The power of the guns is 220 kW, and they can operate for up to 15 hours. If there is a thermostat responsible for periodically disconnecting and turning on the unit depending on the ambient temperature in the room, the gun on one fuel tank can be constantly in operating mode for 24 hours.
It should be noted that the direct heating device consumes oxygen and emits exhaust gases along with the heated air. Therefore, there are restrictions on the use of such devices. They are used in rooms with a constant flow of oxygen. The machine must not be operated in places where people are present, as this will cause carbon monoxide poisoning.
Indirect heating devices
The design of the machines includes a gas outlet, thanks to which warm air enters the room. At the same time, there are no exhaust gases or other combustion products in the air. The operating time of the equipment is up to 16 hours.
The design has overheating protection, which turns off the unit when its surface reaches significant temperatures, and the option of controlling the burner flame. This function automatically turns off the device when there is no flame in the burner, thereby making it safe to use.
The equipment is suitable for use in rooms occupied by people. To maintain the combustion process, an influx of oxygen is necessary, that is, the heated space must be constantly ventilated.
Diesel devices
These devices operate only on diesel fuel and are used during winter construction. Diesel devices are designed with direct or indirect heating. They are less fuel efficient than multi-fuel models. But they are compact, mobile, powerful, thanks to which the space heats up faster and the temperature is maintained for a long time.
If you need repairs of diesel heat guns in St. Petersburg, call our managers. They will advise on issues of interest.
Gas models
The machines ensure complete combustion of the gas on which they operate. Their connection to the gas network makes the unit stationary. Gas appliances are used in agriculture and industrial buildings. It is better to entrust the repair of a gas heat gun to our specialists.
Gas guns can operate on bottled propane or butane. This makes them mobile and allows them to be moved from place to place.
Requirements for installation and operation of an oil furnace
It is required that the stove be located in an empty room, near which there should be no flammable surfaces. Particular attention is paid to self-made devices. They should not be placed on a shelf or other support that could catch fire.
A homemade furnace for mining should be located on a flat base, which can be concrete or brick. It is necessary that the distance between the apparatus and the wall be at least 1 m. To create good draft, the chimney must have a length of more than 4 m. Insulation should be provided on its external side to prevent the formation of acid condensation.
The used oil should not contain any solvent or other flammable element, so such components should be kept away from the furnace. It is also unacceptable for moisture to get into the container with oil. This will cause a fire in the oven. In the event of an emergency, a fire extinguisher should be used to extinguish the fire.
Note! In the room where the stove is located, there must be a good system of natural supply and exhaust ventilation.
The operating principle of a stove with a drip supply of fuel is similar to the operating mechanism of diesel engines.
Before starting work, oil is poured into a container in an amount equal to half the volume of the tank, which will provide the necessary space for the formation of vapor. For the vapors to become enriched with oxygen, you need to wait some time. Then the fuel is ignited using long matches. As soon as the process of ignition of vapors begins, the damper is closed halfway.
To increase the performance of the mini-furnace during mining, you can install a sealed tank with liquid above its upper chamber. To supply and drain water, fittings are attached to it, which are located at different levels. Another option for increasing productivity is the necessary air convection, which is carried out using a fan located near the upper chamber. By taking warm air from the stove, it helps to cool it, which has a positive effect on the life of the device.
Required power parameter
The main indicator of a device is its power, because the effective functioning of the device depends on it.
To determine the required heat output of the device, it is important to simultaneously take into account a number of indicators:
- The volume of heated space, to calculate which it is enough to multiply its parameters (height, width, length).
- The difference between the temperatures outside and inside the room.
- An indicator of heat loss, the magnitude of which depends on the thermal insulation of the room. The average value of this indicator is 1-2, while an uninsulated building has an indicator of 3-4, and a well-insulated house has an indicator of 0.6.
A small value of the required power, indicated in kilocalories per hour, can be obtained by multiplying the above values.
In order to convert a specific figure into kilowatts, just multiply the quantity by 0.001163. This value must be taken into account when selecting a ready-made device in a store.
DIY options for increasing the efficiency of a mini-oven
Waste oil furnaces are often used to heat a garage or small workshop. It is not recommended to use such a device in a building where people are constantly present. This is due to the fact that the stove absorbs oxygen, which has a negative effect on the human respiratory organs. If the device is intended to heat a living space, it should be located in a separate room.
It is not recommended to use such a stove in a room where people are constantly present.
To improve the efficiency of the device, additional devices can be used. A waste oil furnace with a water circuit is organized by tying the coil body or installing a water jacket on the chimney. In the first case, the coil is made of copper pipe. It is built into the heating system of the house.
The water jacket is made of sheet metal in the form of a container, which is located in the upper part of the housing. It circulates a liquid coolant. For the stove to operate efficiently, the tank must contain up to 30 liters of water. Such a device will allow you to heat a large area.
An exhaust furnace with a water circuit must be equipped with an expansion tank with an emergency drain, necessary in case of boiling of the liquid. It is not recommended to install a membrane container here.
Another option for increasing the efficient operation of the furnace is to use an air heat exchanger, which is represented by a fan. No design changes are made to the device, and the heating of the room is improved. The fan is located near the upper chamber. When it cools, the heated air spreads across the area of the room. You can also pass air through a box located on top of the stove, or through a pipe that is installed in the afterburner chamber.
An exhaust furnace with a water circuit must be equipped with an expansion tank with an emergency drain.
Popular options for pre-fabricated furnaces, their characteristics
The Teplamos NT-612 stove is often chosen as a device used for heating a garage. The power of such a drip fanless heater can vary between 5-15 kW. Fuel consumption is 0.5-1.5 l/hour.
This furnace for use in a garage is a closed type device. It is equipped with a chimney, an air supply pipe and a built-in tank designed for 8 liters of fuel. Fuel combustion occurs in the inner chamber. The operation of the device begins with electrical heating of the plasma bowl. When the required temperature is reached, fuel is supplied and air is forced into the combustion chamber. The average cost of the device is 30 thousand rubles.
Note! For normal operation of the stove, it must be preheated with a small amount of diesel fuel, which is poured into a special bowl.
Another popular model is the Zhar-25 (MS-25) stove. This device can operate not only on waste oil, but also on diesel fuel. The device operates from the electrical network, which powers the internal fan. The thermal power of the furnace varies from 25 to 50 kW. It is designed to heat a room up to 500 square meters. m. Maximum fuel consumption is 4.5 l/hour. The device has large dimensions. Its weight reaches 130 kg. This stove needs to be equipped with a good chimney. You can buy it for 45 thousand rubles.
The exhaust furnace is equipped with a chimney, an air supply pipe and a built-in tank.
Appearance
This takes into account such nuances as aesthetic appeal, achieved through the use of two main shapes - rectangular and cylindrical, as well as high-quality paint and the dimensions of the unit. If the device is planned to be used exclusively for domestic purposes in a small room, then a compact heater weighing 5-10 kilograms with dimensions ranging from 25-50 centimeters is the best option. If there is a need to purchase a unit of greater power, then you should be prepared to transport equipment whose weight will be 50-150 kilograms with dimensions of 1-3 meters for each parameter.
Do-it-yourself stove made of sheet metal and pipes
Depending on the type of device, the structure can be created from pipes of different diameters or from iron sheets. To work you will need the following tools:
- grinder with cutting and grinding wheel;
- sheet metal and pipes;
- welding machine and electrodes;
- metal corners;
- metal paint that can withstand high temperatures.
Before making a furnace for testing, a detailed drawing of the apparatus is made. You can create it yourself or use ready-made options that are easy to find on websites on the Internet.
The first step is to make the lower part of the chamber connecting to the fuel tank. It looks like a rounded or straight tank with a lid where two pipes are located. The first is used to supply oil, and the second is used to strengthen the pipe that goes into the middle part of the device. Elements for the tank are cut out with a grinder and connected according to the drawing.
Depending on the type of device, the structure can be created from pipes of different diameters or from iron sheets.
The bottom and metal corners are welded to the walls of the tank, which act as the legs of the structure. To create a lid, a sheet of metal is taken and holes are made in it. The first, with a diameter of 100 mm, is located in the center; the second, 60 mm in size, is located closer to the edge. The lid should be removable, which will make cleaning the stove easier.
A pipe about 37 cm long and 100 mm in diameter is used to supply oxygen. It has holes along the entire length of the element necessary for the supply of oxygen. The pipe is welded perpendicular to the cover at the bottom of the apparatus. An air damper is fixed on it, which will be secured with a rivet or bolts. The hole under the damper should be 6 cm in size. It is intended for supplying oil and igniting fuel.
The design of the upper tank is carried out by analogy with the design of the lower tank according to the drawing of a furnace using waste oil with your own hands. The walls of the product must have a thickness of at least 350 mm. A bottom with a diameter of 10 cm is cut out of the bottom of the tank, which should be placed closer to the edge. A small piece of pipe with a diameter of 11 cm is welded to the bottom of the hole. This is necessary to connect the element to the gas combustion tank.
Before making a furnace for testing, a detailed drawing of the apparatus is made.
Since the top cover of the supercharged exhaust furnace is exposed to high temperatures, a metal sheet with a thickness of at least 6 mm should be used for its manufacture. There is an opening in the lid for the chimney pipe, which should coincide with the opening at the bottom of the container. Between these elements, a partition made of dense metal sheet is mounted, located near the smoke hole. A pipe is attached to the top of the lid, connecting to the chimney part. The self-production process can be seen in detail in the video of the furnace being tested.
Note! To give the structure rigidity and stability, a metal spacer in the form of a piece of pipe with a diameter of 200-300 mm is welded between the chambers.
Making a drip heater
Most often, craftsmen use old oxygen and propane cylinders with a diameter of 220 and 300 mm, respectively, to assemble droppers. The former are preferable because of their powerful thick walls that can last a long time and not burn out. A pipe made of low-carbon steel (St 3-10) with a wall thickness of 5 mm or more is also suitable.
Advice. The ideal option for a durable housing is a pipe made of heat-resistant stainless steel alloyed with chromium, molybdenum or nickel (for example, 15X1MF or 12X18H12T) with a wall no more than 3 mm. Perhaps you or a neighbor has one in your garage. There is no need to buy it specially - it will be too expensive.
Select rolled metal for other parts according to the drawing of the furnace with top feed of waste into the combustion zone. The blower fan is a “snail” from a VAZ 2108 cabin heater or its Chinese equivalent, the fuel line is a stainless tube with a diameter of 8-10 mm.
The manufacturing technology is as follows:
- Make a fire bowl from a piece of pipe or take a ready-made steel container. It must be removed through the inspection hatch, so do not make the tray too large.
- Cut openings in the body for the chimney pipe and cleanout hatch. In the latter, make a frame and install the door (possibly bolted).
- Make an afterburner. Take your time to drill all the holes indicated on the drawing; do the bottom 2 rows first. You will complete the rest while setting up the oven.
- Weld a cover and an air duct with a flange for mounting the fan to the afterburner. Attach the fuel supply device as shown in the photo.
- Assemble the heating unit and connect it to the chimney.
Advice. For greater stability to the body, it would not hurt to weld a frame from a steel profile or angle according to the example shown in the photo.
The afterburner in the photo is a close-up - side and end views
. To regulate the heating power, you need to provide a fan speed control and a device for dosing the fuel supply (as a rule, an auto-drinker with a jet break is used). According to reviews from craftsmen on a popular forum where heat extraction issues are discussed, fuel consumption in the furnace can be monitored visually. The trend is this: if the oil flows in drops at the break in the stream, then less than 1 liter per hour burns, and when a thin stream flows, more than 1 liter per hour.
Recommendation. Control the fan performance using a cheap Chinese PWM controller (price is about 8 USD).
Different designs of drip bowls
After igniting and warming up the heater, it is necessary to set the optimal operating mode. The procedure is carried out according to the same scheme as with the miracle stove: you need to achieve the most transparent smoke from the chimney by drilling additional holes in the afterburner. The ideal flame color is blue, normal is yellow, and reddish is unsatisfactory. In the latter case, low heat transfer, high consumption and soot formation are observed. For details about the design and assembly of the furnace, see the video:
Step-by-step instructions for making a waste oil stove with your own hands from a cylinder
The device can be made from old items using the presented drawings of a waste oil furnace. For this process you will need a gas cylinder with a capacity of 50 liters. You should also prepare:
- pipe with a diameter of 80-100 mm and a length of 4 m;
- steel corner for making a stand and internal elements of the heat exchanger;
- sheet steel for making the bottom of the upper chamber and the plug;
For the manufacturing process of a waste oil furnace, you will need a gas cylinder with a capacity of 50 liters.
- brake disk;
- fuel supply hose;
- clamps;
- half-inch valve;
- loops;
- half-inch oil supply pipe.
An empty gas cylinder is used to make the body. You need to unscrew the valve on it, after which you should leave it outside overnight to ventilate the remaining gas. A hole is drilled in the bottom of the product. To prevent the formation of a spark, the drill must be moistened with oil. Through the hole, the cylinder is filled with water, which is then drained, washing away the remaining gas.
Two openings are cut in the cylinder. The top one will be used for the combustion chamber, where the heat exchanger will be installed. The lower one acts as a burner with a tray. The upper part of the chamber is specially made large. If necessary, it can be filled with other fuel options in the form of firewood or pressed briquettes.
A stove made from a gas cylinder will be more economical and efficient than one made from other materials.
Next, the bottom for the upper compartment of the device is made from sheet metal 4 mm thick. A burner is made from a piece of pipe 200 mm long, as shown in the drawing of a waste oil stove. There are many holes made around the circumference of the product, which are necessary for air to enter the fuel. Next, sand the inside of the burner. This will eliminate the possibility of soot accumulating on the ends and uneven surfaces.

The furnace burner is exhausted from a gas cylinder and welded to the bottom of the upper chamber. If there are no mining reserves, wood can be laid on the formed shelf.
Briefly about the main thing
An electric probe, a heated drain plug, a heating element and a heating plate - with these simple means you can safely heat the oil inside the engine in winter before starting. In fact, you don’t need to invent anything - each of the four options is available for purchase on many trading platforms.
In terms of power supply, there are no difficulties: a wire and a plug or a simple electrical circuit based on a relay and a toggle switch. Another question is whether it is necessary. The answer is short and advisory in nature: it is necessary, especially in cold weather worse than -10°C.
Many motorists are forced to think about how to heat the engine sump with their own hands due to the weather conditions in winter, which affect the normal starting of the engine. Some drivers mistakenly believe that in winter it is difficult to start the power unit due to weak battery power. In fact, the problem is caused by a change in the lubricant, which becomes very viscous, making it difficult to start the engine and the functionality of the crankshaft.
Ineffective lubrication in the initial minutes of engine start leads to excessive wear of the piston unit. These troubles can be avoided by heating the crankcase and eliminating excessive oil viscosity.
Making a tray for working off and installing a chimney for an oil stove with your own hands
According to the drawing of the stove, a cast iron automobile brake disc, which has good heat-resistant characteristics, is used to make a waste oil pan. A steel circle is welded in its lower part, which forms the bottom. At the top there is a lid through which air enters the oven.
A cast iron automobile brake disc is used to make the pan.
On a note! It is better to make the opening wide. This will provide sufficient air draft so that the oil will flow into the pan.
The next stage in the manufacture of a stove using waste oil from a gas cylinder is to make a coupling from a 10 cm long pipe that connects the burner and the pan. Thanks to this element, servicing the stove will be much easier. You can remove the tray and clean the bottom of the burner. To ensure the supply of oil, a metal tube is inserted into the hole in the housing and secured by welding. An emergency valve is installed on the pipe.
The chimney structure is made of a pipe with a diameter of 100 mm. One end of it is welded to the hole in the central upper part of the body, and the other is brought out to the street.
On a note! The chimney pipe through the wall must pass through a special fireproof glass.
By watching the video “Furnace using a gas cylinder”, you can familiarize yourself with the sequence of actions in the manufacture of the device.
Chimney installation
Stove chimney
For such structures, stable, powerful traction is very important. Otherwise, the fuel will begin to fade and smoke. Therefore, the chimney is made with a length of 4 m. An increase in draft helps remove combustion products from the room, which reduces the likelihood of poisoning from them.
The diameter of the pipe should be sufficient - on average about 100 mm. Soot in such structures collects much faster than in conventional furnaces, so bends, as well as tilts, are unacceptable - the pipe should be installed strictly vertically. Therefore, when choosing a place to install a potbelly stove, you should first find a convenient hole for the chimney.
The part of the pipe leading outside should be insulated. Otherwise, the oven will have to be cleaned more often - condensation, mixing with soot, will settle on the walls. The chimney in such devices is made collapsible so that it can be easily removed and carbon deposits removed.

How to make a pyrolysis type stove
A potbelly stove during mining consists of three main elements:
- oil containers with lid and valve;
- closed combustion chamber;
- afterburning chambers.
The stove must have a chimney, the length of which is at least 4 m. The oil container, according to the do-it-yourself potbelly stove drawing, is made from a piece of pipe with a diameter of 345 mm and a length of 100 mm. A sheet metal cover is welded to its lower part. The removable top cover is made of a pipe with a diameter of 352 mm, to which sides with a height of 600 mm must be attached by welding. The lid has a central hole of 100 mm in size, intended for the combustion chamber, as well as a side hole (60 mm in diameter) for air injection, which is closed by a rotating lid.
Note! By adjusting the clearance of the blower, you select the combustion intensity of the stove, which affects the air temperature in the room.
According to the drawing of the stove during testing, a pipe with a diameter of 352 mm and a height of 100 mm is used to make the afterburner. Holes measuring 100 mm are made in its lower and upper parts. The first is for the combustion chamber pipe, and the second is for the chimney. Closer to the chimney opening, it is necessary to weld a partition 70 mm high and 330 mm wide.
Diagram of a pyrolysis-type furnace.
Using a drill, holes are made in the combustion chamber pipe along its entire height, leaving the lower zone 20 mm high and the upper zone (50 mm) unused. After completing all welding work, the tightness and reliability of the seams should be checked. Next, a furnace test is organized. The waste is poured into the oil container. Kerosene is added on top. Careful ignition is carried out with the ash pan open, with the help of which, after heating the oven, the heat intensity is adjusted.
Note! Testing the furnace during testing should be carried out outdoors, which will avoid a fire indoors or other accident.
To heat a garage, small workshop or living space, you can use a waste stove, which has a number of advantages. The device can be purchased ready-made or made independently using drawings from the Internet. Before making a stove, you should study the sequence of actions in order to subsequently obtain a practical and effective device.
How to use a homemade unit correctly?
The unit described above should not be placed near mixtures or objects that can easily ignite, or in a draft. It is also important that the stove chimney is completely sealed, and there is at least 50 centimeters of free space around in each direction. It is imperative to ensure that no water gets into the fuel used, otherwise it will splash out of the holes in the pipe.
The “working” will heat up very quickly. Fill the container to two-thirds of the height, then, adding 25 grams of gasoline or solvent, ignite the resulting mixture through the fuel filling hole. For ignition, it is preferable to use a burning wick screwed to a piece of wire.
Note! Check regularly how the unit works. Use the plate to adjust the burning intensity. Never leave a working oven unattended!
