With the onset of cold weather, people begin to think about how to heat a house, dacha, garage, office and other premises. One of the solutions is to purchase a diesel heater. In the modern world, there are no problems with the choice, because the market offers a large assortment of these devices, which differ in the principle of operation, manufacturer and cost. In this review, we will help you decide on the type and model of a diesel heater.
Diesel heater device and principle of its operation
The principle of operation of a diesel heater is very similar to an electric one, but the difference is that the former runs on diesel fuel, while the latter requires electricity. Diesel heaters are supplied with:
- The combustion chamber;
- Spark plug;
- Fan motor and impeller;
- Pump;
- Filters for air purification at the inlet and outlet;
- Fuel tank;
- Controller;
- Pipes through which air enters;
- Flame stabilizers;
- Fuel nozzles.
Diesel fuel is poured into the tank, from where it enters the combustion chamber. Next, the fan will blow the air in order to ignite the fuel. Filters purify the air from various particles and combustion products of liquid fuel, and controllers regulate the air temperature.

Place of use of diesel heater
Liquid diesel heaters can be used in different rooms. The place of application depends on both the dimensions of the device and the size of the heated room. For example, small units like heat guns are perfect for a garage.
Infrared diesel heaters will perfectly fit where it is necessary to heat the air in an open space: a cafe, a veranda. Note that this type of device is also suitable for a closed room.
Solar gas heaters can be taken with you, for example, on a hike, and cooked on it, and it is also perfect for heating a summer cottage.
We will talk about all these types of devices a little later.
Varieties of diesel heaters
Diesel heaters are divided into the following types:
- Stationary;
- Air;
- Infrared;
- Direct acting devices;
- Indirect action units.
The difference between the last two is that direct fired heaters are not equipped with filters and air outlets for combustion products. It must be remembered that when such a unit is in operation, the latter immediately enter the room in which it is located. Therefore, they are used in non-residential premises or for urgent repairs during cold weather.
Heaters of this type are characterized by a combustion control system. Note that it works in automatic mode.Large fuel tank allows refueling every 10-15 hours.
Indirectly heated diesel heaters do not emit combustion products into the environment, which has been achieved through the use of filters that purify the air. These devices are perfect for residential applications.

Infrared Diesel Heater
This type of unit can be used to heat buildings with high ceilings, because they are usually installed on the ceiling or wall. Infrared radiation will help to heat even gazebos located in the air.
Such heaters act in a similar way to solar radiation. When fuel is burned, heat rays are generated, aimed at heating objects, people or walls, which, in turn, with their heat, already heat the air in the room. This helps to save fuel consumption, which is undoubtedly an advantage. These devices are recommended for use in those rooms that are characterized by poor thermal insulation or there are restrictions on the use of electricity or there is a shortage of it.
Air Diesel Heater
The operation of an air heater is similar to that of a fan. This unit is equipped with a robust housing that protects against overheating and mechanical damage. Heat guns, a type of air heater, heat a room by moving a warm stream of air and are often used in non-residential areas.
The main feature of this type of heater is that it heats the room for as long as it works. This means that if you turn it off, the temperature in the building will drop sharply.
Pros and cons of diesel heaters
As with any device, the diesel heater also has its pros and cons.
Benefits:
- Compact size;
- Autonomy;
- Economical - from a financial point of view, the purchase of diesel fuel is much cheaper than electricity;
- Mobility - you can take it with you or move it to the most convenient place;
- Large assortment of heaters.
In addition to all of the above, modern models have additional functionality, are as economical as possible, and they can be controlled remotely.
Disadvantages:
- The high cost of the unit;
- High noise level during operation;
- Combustion products that can be emitted when the room is heated.
Why are diesel heaters better than others?
Among the main advantages are the following:
- Efficiency is about 90%;
- Economical fuel consumption;
- Fast and high-quality heating of large rooms;
- Wheels that help to quickly move the device from place to place;
- Variety of types of diesel heaters and their capacities;
- Economical consumption of electricity;
- Combustion and safety control takes place automatically;
- Fuel tank - allows the heater to work for a long time without refueling.
Diesel heater selection criteria
Undoubtedly, each person, before purchasing any unit, adheres to certain criteria, which he prefers. When choosing a heater, the criteria may be as follows:
- Air exchange. This indicator is very important for heat guns. The higher this value, the more the heat fluxes accelerate, and, consequently, the room heats up in a short period of time;
- Fuel consumption. It must be borne in mind that about 10 kW of power should be obtained from 1 liter of fuel;
- Direct and indirect action. For the first type of heaters, additional ventilation is required, because combustion products go directly into the room. For this reason, they are impractical to use in small and confined spaces. Indirect action units are equipped with filters, unlike the first type, they are not so economical;
- The ability to change modes.It is very convenient if during the operation of the heater you can change its power. It is also economical, because some devices with minimal heating are able to function without refueling for two weeks.
- Timer. With its help, you can set the time during which the heating will be intense, after which the heater will turn itself off;
- Noise. When the diesel heater is operating, there will be noise in any case. This is a fundamental indicator, then it must be taken into account. Note that an indicator of 45 dB can be considered appropriate;
- The presence of wheels. Large heaters are equipped with wheels to make them easier to move
