Diesel cannon is a heat source for heating large areas. It is used, as a rule, in non-residential premises. They buy it for a garage or summer cottage. It is used during construction works, especially in winter. Indispensable during repairs.
An indirect heating heat gun is a high-power unit capable of operating for a long time, about 16 hours, without refueling. A diesel generator generates heat during combustion.
In order for the purchase of the device to be as useful as possible, you need to know what models are, in what conditions they should be used, what selection criteria exist and what you should pay attention to. The editors of the site "bestx.htgetrid.com/en/" made a rating of quality heaters, according to buyers. The article talks about how to choose a device for heating a room and what mistakes there are when choosing.

A bit of history
An interesting fact is that the first fuel injector appeared in the second half of the 19th century thanks to the Russian engineer A.I. Shpakovsky. The system had a number of shortcomings, therefore, as such, it did not receive distribution.
14 years later, V.G. Shukhov, while still a student at the Moscow Higher Technical School, invented a nozzle designed for burning fuel oil. From this discovery and the beginning of the widespread use of technology on diesel fuel. It is this nozzle that is used to this day. True, it has undergone a number of upgrades.
Diesel cannon device
Heaters consist of the following units:
- combustion chambers;
- fan;
- burners;
- fuel tank.
Many popular models have wheels for easy transport. In order for the device to work autonomously, the unit is equipped with a timer, a thermostat, and an electronic flame control system.
Principle of operation
A compressor or pump transfers fuel from the fuel tank to the injector. It distributes fuel through the combustion chamber. The fuel is flammable. In order for the combustion process to proceed without interruption, holes are provided in the combustion chamber through which air penetrates. Part of the air moves along the walls of the chamber and heats up. Due to heat exchange between hot and cold air streams, heating occurs.
Types of diesel heaters
There are two broad categories of heat guns:
- direct heating,
- indirect heating.
Direct heating differs in that the combustion chamber is open. During the operation of the device, combustion products end up in the room. It is used only for non-residential areas with a good ventilation system.
The advantages include high efficiency, and the disadvantages are that it cannot be used in rooms where a person stays for a long time.
Indirect heating models have a closed chamber equipped with a branch pipe that connects to the chimney and removes combustion products through it. The room still needs periodic ventilation.
Advantages:
- can be used in spaces where people are for a long time.
Disadvantages:
- power is lower than that of direct heating units;
- the heating of the room is a little slower, since the outlet air has a lower temperature.
If we talk about diesel heaters in general, they have a number of advantages and disadvantages over gas or electric ones.
Advantages of diesel heat generators:
- High efficiency. The cannon heats the air quickly and efficiently.
- Convenience and ease of use. The device starts to work when you press just one "power on" button. The muzzle of the technique is directed to the center of the room.
- Safety. All types of heaters are equipped with special sensors and indicators that warn of an increase in temperature, preventing the device from overheating.
- The cost of diesel fuel is lower than the cost of gas. Electrical appliances are also more expensive.
- Mobility.
- Economical fuel consumption.
- Long service life.
Disadvantages:
- Diesel oil that is released into the air during operation of the device is harmful to health. This applies to direct heating appliances.
- The fan makes noise during operation.
- The need for a network connection.
- The cost of a diesel cannon is higher than the price of an electric unit or a gas powered device.
