Choosing the best small heat gun
Unfortunately, most of the time of the year we are not very happy with warmth. Yes, and heating networks do not always keep up with the vagaries of the weather, especially in the offseason. In order not to freeze in private houses and work comfortably in offices, it is necessary to use special devices. Compact heat guns are recognized as one of the most efficient devices.

What is such a unit
This is a universal device with which the heating of any room takes place. Their action is especially noticeable in small rooms without additional heating. The principle of operation of the units is point feed warm air flow.And this advantage creates an additional advantage compared to conventional heaters and convectors in oil: the latter can not cope with the heating of a large volume of air.
The concept of almost all devices is the same:
- The heater is enclosed in a metal case, which has a mandatory hole for air intake.
- A fan inside the device converts a stream of cold air into hot air and contributes to its distribution throughout the room. The exit is carried out through a heating element.
The main advantage of such a device is high performance. It is she who contributes to the uniform distribution of warm air even over large areas, because the thermal efficiency is very high. In addition, usually in such devices provides economical fuel consumption. And if there is a thermostat in the device, then the time of its use can be controlled: for example, the gun will turn on if the air temperature has dropped below comfortable.
Of course, there are many models on the modern market. There are also those that are suitable even for a small apartment - mini-formats of such heating units will not occupya lot of space, but will adequately cope with the work.
Varieties of devices
Devices are classified by used fuel:
- gas heat suppliers;
- electrical units;
- diesel fuel;
- waste oil as a source;
- infrared option;
- water cannon.
Gas
This type is recognized as one of the most economical - a residential house is heated at minimal cost. Even in the “competence” of even a small heat gas gun - operational heating of storage and hangar premises, as well as construction sites. At the same time, work efficiency does not fall in open areas.
How does such a device work? This is due to the fan and heat exchanger. The first part forms the air flow, and the gas itself burns in the heat exchanger. Everything is extremely safe: all elements are hidden in a durable metal case. The flame is ignited using the piezoelectric method or automatically.
- From a special cylinder, the gas enters the combustion chamber.
- Burner openings are ignited.
- The heat exchanger heats up with the air flows through it.
Gas fuel, however, does not rotate the fan itself - you still need to connect the entire device to network. Compact apartment models consume little power (from 10 to 100 kW). At the same time they are easy to move around the room using a special pen or wheels.
Electric
Here, the air is heated by means of a heating element or a spiral that is similar in function (also hidden by a metal casing). The ease of operation is obvious:
- When connected to the mains, the heating element automatically warms up in the device — in this way, the desired temperature is injected for a short period of time.
- The flow itself is further distributed using a fan.
When buying this type of gun, be sure to consider power selection. In relation to this criterion, one should proceed from a potentially heated quadrature.
The maximum power of the device will reach 20 kW.
Diesel
The composition of such equipment is slightly different from previous ones. These include:
- fuel tank;
- burner (burner);
- ventilating element;
- the combustion chamber;
- timer and thermostat in the presence of a controlling electronic system.
The work will be as follows:
- When the pump (or compressor) is running, fuel will go into the combustion chamber directly from the fuel tank. In this case, the fuel burns, supported by oxygen inflows.
- Heat transfer between cold and warm streams will warm the room.
It is best to exploit such miniature cannons with diesel fuel for non-residential premises.. Of course, it can also be used for inhabited apartments, but it should also have excellent ventilation. The devices themselves may be direct and indirect heating: in the first case, the combustion chamber is open, and the combustion products enter the room immediately. And for closed variants, a closed combustion chamber is characteristic, and all products are immediately displayed through a special chimney. Most often the power of guns is 85 kW.
Waste oil
Used oil is also suitable for using it as a fuel - and it will be not only economical, but also reasonable from the point of view of caring for the environment. Oil will burn well: this is how the device functions. The fuel enters the burner bowl, where, burning, it will give off heat to the air. As for the exhaust elements, they will go through the chimney.
A big plus - the device is easy to maintain and efficient in operation.
Alternate
There are unusual offers on the modern market. First of all, it’s about infrared options. Here, the appropriate radiation is used as fuel, heating the air flow. Another non-standard option - thermal water. Heat the air in this case will be hot water.
The nuances in the use of heat guns
The main requirement for such a device is the safety of its work:
- There should not be flammable objects near (especially if you are using the gas version or a device made of diesel fuel).
- The air flow is not recommended to direct to synthetic materials.
- The device must be on a flat surface.
The last point is to add the correct location. There is one thing: if the ceiling height is more than three meters, it is best to work under the ceiling fan. So the air flow will be distributed evenly throughout the room. It is better to direct the "barrel" of the gun to the working area.
In order for the heating to be of high quality, you should correctly calculate the required power of the device.Here not only the volume is important, but also the temperature difference. Knowledge is very important for fuel economy.
In today's market, all offers come with technical specifications, so it will not be difficult to choose the necessary offer. It is quite possible to choose the optimal heating rate.
Review of popular models of compact heat guns
The range of such a product on the market can stump an inexperienced beginner. Let's try to analyze the most popular models.
Among electrical options The top positions are confidently headed by the TPE-3 model from Interskol. The domestic brand actually proved its viability - the device can even be used as the main heating device, and the lightweight design allows you to move it to the desired place (which will often have to be done because of the short cord). Among the advantages of the device with power from 1.5 to 3 kW can be identified:
- a fan having a metal impeller;
- TEN with the increased thermolysis;
- the ability to adjust the tilt of the device.
Gas device MASTER BLP 17M American brand is not inferior in its competitors.It is able to heat warehouses, workshops, garages and other large premises with a capacity of up to 655 m³. Power in this case will be 10 to 16 kW. The device simply connects to the gas cylinder with a gearbox and starts working.
There is only one drawback - it is a mechanical ignition.
The best diesel gun It is considered Master BV 77E - in it indirect heating and an average level of ventilation are captivating. The air will remain clean even with such liquid fuel, and the room will be evenly heated. The design of the gun is durable and reliable, there is a stainless steel chamber, a protective thermostat and even a flame control. The device is able to provide the room with a powerful air flow. Thermal power at the same time reaches 20 kW. The only drawback is the high cost of the device (at least 52,000 rubles).
And one more interesting offer can be called Profteplo DK-36PL. The device is infrared heater, but it works on diesel fuel. This unique device will emit warming infrared radiation. It is a kind of absolutely safe small sun, the heat from which warms the whole space in the room.The Russian unit itself has a power of 36 kW, and its fuel tank is designed for 53 liters. The power can be adjusted, and in addition there are: overheat protection, flame level control and a fuse.
You can find a device based on your own preferences and wallet. And you can dare and do something like this with your own hands.
How to make a heat gun with your own hands
If necessary, such a device can be "pile" and independently. This product can be heated basement, garage, cellar. The process is not as complicated as it seems:
- Two cases are made - one will be on top, the second - on the bottom. Bottom will play the role fuel tank. The material itself should not be very conductive, which protects the case from heating. Some masters cover the fuel tank also with high-quality insulation.
- The body for the heat gun is located directly above the fuel tank. A pump, a fan, a combustion chamber and a nozzle are placed in it (in the case of a diesel variant).
- For the fuel tank should choose a pipe made of thick metal.The instrument case itself cannot be supported on it (the distance between them will be better than 20 cm).
- Between the two blocks must be installed fuel filter. It will be connected to the tank with a metal tube, the diameter of which is half the size of the gun body. By orientation, it is in the middle of the device - it is with its help that decay products will be released.
- The process is as follows: the fuel gets to the nozzle, after which it will be ignited. The combustion process is in the immediate combustion chamber. The fuel itself is ignited into the metal tube.
So, if you wish, you can make a heat gun with your own hands, but you need to understand the features of its design. The big plus in this case will be that it will be easy and easy for the master to repair such a child.
