Gas heat gun: principle of operation and classification of structures

In rooms where there is no centralized heating system in winter, it is rather difficult to maintain an optimal microclimate for living. Therefore, most owners of country and private houses prefer to buy a gas gun for space heating. This type of equipment has a high rate of efficiency, while the consumption of electrical energy is minimal.

In fact, such a gun is a heat fan that runs on gas. These designs have many advantages. Among the most significant advantages are the affordable price of gas guns on bottled gas, their mobility, as well as a simple system of operation.

The demand of these heaters of the modern generation increases during the heating season if the central heating system is absent or does not work well enough. The design emits warm air into the room, which is formed due to the combustion of fuel – gas.

The unit is enclosed in a metal case with outlets designed for hot air. The shape of the gun is streamlined, inside it contains the following elements:

  • fan;
  • burner;
  • control device;
  • heat exchanger;
  • ignition device;
  • thermostat.

In addition, in the case there may be additional components that depend on the model and design features.

The popularity of gas guns due to their practicality and a wide range of applications. These units are used not only for heating, but also for ventilation of rooms, as well as for drying items with large dimensions. Despite the large range, there are only two types of structures: gas heat guns of indirect heating and direct.

Note! During the operation of the gun is the inevitable burnout of oxygen. For this reason, it is not recommended to use them in rooms where there is no ventilation system. It can be life threatening.

Direct heating structures do not have the function of purifying airflow from burning, therefore, in residential premises, they can poison oxygen. This is the only drawback of such units. Directly heated guns have a 100% efficiency and work by spending the minimum amount of fuel and electrical energy.

In gas guns of indirect heating, a ring type heat exchanger is used as a heating element. The principle of operation of these devices differs from the previous version in that the design first burns fuel, and then poisonous products, which are separated as a result of this process.

Gas guns of indirect action belong to the category of environmentally friendly devices. For this reason, there are no restrictions regarding their operation. It is allowed to install guns of indirect heating in rooms where ventilation is limited. Designs have only one major drawback. The housing is equipped with a chimney, which significantly affects the mobility of these devices, and also complicates their transportation.

Before you go to the store to buy a gas gun to heat a dwelling, it is worth exploring in detail the principle of operation of such units, their internal structure and other parameters.

Gas gun heat: equipment specificity and rules of use

Gas gun works according to this principle:

  1. A burner is installed in the combustion chamber where gas is supplied.
  2. The ignition device ignites the fuel, thereby heating the heat exchanger.
  3. Moving fan elements draw in cold air from the room and direct them back through the heat exchanger design.
  4. Protection of the device from damage and overheating is provided with a thermostat.

When the indoor air warms up to a certain level, the thermostat is activated. At this point, the circuit breaker breaks the circuit and the device stops its operation. This principle of operation allows you to control the temperature in the room and maintain an optimal microclimate.

Heaters are most often used for domestic needs. Moreover, the majority of buyers, choosing the optimal device, would prefer to buy a gas heat gun of indirect heating with a mobile design, which is equipped with control knobs and wheels.

In stationary models, there is a gas cylinder that makes it difficult to move. The technical characteristics of the gun, as well as the duration of its operation depend on the volume of this tank. Models with a fixed structure are considered obsolete, since they are less practical than mobile options.

Note! Compact models of guns that run on natural gas are very economical. Consumption unit is only 1 l / h.

Heat gun is a self-heating device. However, it can play the role of a constructive element of the whole installation, designed to maintain the necessary microclimate in the room. Constructions working on natural gas can be used to heat specialized and automotive vehicles.

The capabilities of this equipment will be useful in the repair process and even when installing stretch-type ceilings. The fan present in the design accelerates the processes. Control of heating the air flow is carried out by the built-in temperature regulator.

This type of equipment, like a gas gun, is in demand not only in the conditions of everyday life, but also in production. The scope applies to heating of residential and non-residential premises. The guns are used for drying individual components with production and automotive direction.

In addition, the functionality of gas equipment will be useful on large areas, the size of which exceeds 25 m ?.

Non-residential premises collect dampness, which adversely affects storage. These rooms include a garage. High humidity is bad for a vehicle that has been in it for a long time. To remove dampness from the walls, as well as get rid of the fungus, experts recommend buying a gas gun for the garage. The cost of such units is quite high, but the universality of such structures justifies the costs, since they can also be used at the country house and at home for rapid heating.

Power of heating devices is in the range of 10-100 kW. If there is no ventilation system in the room, the efficiency of the gas heat gun for the garage is reduced to zero. It is impossible to stay in a room with a working appliance for a long time, and as a result of the constant opening of the gate for airing all the heat injected will simply go outside.

The use of a heat gun in the garage will create conditions for the normal start of the car engine, as well as the performance of repair work in the winter season.

In a heated room, any processes are significantly simplified and accelerated:

  • tool sorting;
  • rubbing the car body and glasses;
  • interior cleaning, etc.

To select a device with optimal performance, you need to consider the following points:

  • the material from which the garage is built (brick, stone or metal);
  • the quality of thermal insulation (types and features of internal and external insulation);
  • the absence or presence of electrical wiring in the room (without electricity, the gun will not be able to work);
  • features of the ventilation system;
  • total area of ​​the room;
  • operations that are carried out in the garage.

Note! After using the device, the room must be ventilated for at least 10 minutes.

Devices for space heating are of two types. Some of them consume liquefied gas. In such constructions, butane or propane can be used. Other types of gas guns for heating are universal. A pressure stabilization component is built into their housing. The presence of this device allows you to connect equipment directly to the gas line.

Depending on what kind of fuel is consumed by the device, it may have different characteristics. The network gas pressure varies in the range of 0.015-0.02 MPa. Therefore, guns are designed for different indicators of input pressure. In this case, the output of the gas cylinder reducer has a value of 0.036 MPa.

The differences between the models also affect the nozzles, which may have different diameter nozzles. This design feature is due to the composition of the fuel. Calorie liquefied and natural gas differ significantly. The balloon fuel variant is three times more caloric than that supplied by the mainline. For this reason, it is not allowed to use natural gas as a substitute for liquefied fuel, unless the design of the gun provides such an opportunity. This information is prescribed by the manufacturer in the instructions that are attached to the device.

Heat guns on gas are designed for domestic and commercial use. They are easy to operate and economical. Such installations can be a great alternative to the standard method of heating. The range of modern stores presents a large number of modifications with different technical characteristics. Due to this, buyers can choose the optimal design for space heating of a compact size, for example, a garage or a living room, and a large area (shopping centers, airports, railway stations).
