The principle of operation and the rules for choosing a heat gun on gas

Products of this class are used as permanent or temporary sources of heating - everything depends on the state of the thermal insulation of the room. In practice, this is an ordinary fan heater, only having a high degree of efficiency and unique functionality. Natural gas heat guns are used for high-quality and economical heating of greenhouses, greenhouses where flowers and vegetables are grown: during operation they do not emit combustion products, unlike guns operating on diesel, as well as more economical than electrical counterparts.

Design features

The principle of operation of this class of units does not differ from other heat guns: the casing of the combustion chamber is cooled by air blown by a fan. Then the warm air is sent to heat the room. Gas heat guns differ structurally from their electrical counterparts only by the presence of a burner instead of a heating element (TEN). Gas ignition occurs automatically using a piezoelectric element.

This device can be used both for residential premises and for heating production capacities. For example, a 10 kW high-performance gas heat gun can heat a room in a new house of 150–300 square meters. m. or greenhouse up to 70 m². If the gun has a capacity of 10 times greater, then it is able to heat the building with an area of ​​about 3.3 thousand square meters. m or greenhouse - 740 m².

One propane gas cylinder lasts for about 60 hours of operation without stopping; it must be borne in mind that the fan heater is automatically switched off when the set temperature in the room is reached, and then it turns on if the temperature has decreased. For battery life A gas cylinder with liquefied natural gas is connected to the product and can be easily replaced as used.

A compact heat gun, capable of operating on natural gas, consumes a total of not more than 1 l / h to heat a dwelling.

Product classification

Gas-fired heat guns are divided into two main classes:

• products of direct heating of the air flow;
• indirect heating units.

In the first case, when used to heat the air flow open fire, in which propane gas burns, the products of combustion enter the heated room, but the efficiency reaches its maximum when using this design. The dimensions of such a device are quite compact, very low cost, but ventilation is required for a constant flow of fresh air. Greater fire hazard - no inspector will sign the act of authorizing the use of this device for residential premises.

The second option is preferable because the combustion chamber in the unit closed type, all products of combustion are discharged through a special pipe connected to the chimney. Such products are better to install in the open air, and to force warm air through a special system with a large-diameter sleeve made of non-combustible material.

Modern gas heat guns, which carry out indirect heating of the air flow, operate on propane, which burns without residue, and the removal of combustion products is no longer needed.Only their dimensions are larger than direct heating devices, respectively, and the price is higher.

Requirements for use

The functioning of the product, working on gas, regardless of the design features requires a constant flow of oxygen from the ambient air for stable combustion. When the user selects a model, it is necessary to take into account these features.

The pricing policy depends on the size, power and brand: the more difficult the working conditions, the greater the volume of heated space, the more expensive the heat gun on gas fuel will cost.

The room where the unit is planned to be located must have excellent ventilationso that fresh air is constantly flowing outside. If there is no ventilation, then you need to choose a model with a thermostat that automatically turns off or turns on the gun, maintaining an adequate level of oxygen. Equipment thermostat allows you to improve the efficiency of the product: when the optimum temperature is reached, it turns off the fan heater, turning it on only when the set temperature is reduced to a certain level.This class of products are used in production, in warehouses, in the construction of buildings and heating of agricultural facilities, where people are not constantly present.

Unit selection

The entire model range of gas products has a very high efficiency, and the fact of environmental cleanliness is also important - the burned gas does not pollute the atmosphere, there are no extraneous smells, which is very important for farmers involved in cultivating flowers and growing vegetables.

How to choose a fan heater that runs on gas from a wide range of models presented? To successfully make a choice, it is necessary to learn more about the blue fuel used, the specific features of thermal units and their device.

1. It should be noted that similar heaters successfully operate from highways or from connected to a gas heat gun cylinder. The efficiency of such a device becomes almost 100%.
2. To purchase the right product with effective performance, you need to calculate in advance what kind of power the unit needs. Are being made room measurements: you need to know its volume. You should also check the quality of insulation, whether there will be leaks.The higher the performance of the heat gun, the faster it will heat the room to the desired temperature.
3. Pay attention to gas consumption, to know how much the gun will work without first shutting down.

All gas heaters have a similar working scheme, how it works, we have already discussed in detail a little earlier. It is necessary to note the fact that many people do not need to connect to the network, because piezoelectric element can ignite gas without electricity.

TPG-10 kW for 7 thousand rubles is considered by experts to be the best option for those places where there is no electricity connection nearby:

• works on propane and butane;
• performance - 300 m³/ h;
• temperature up to + 90 ° C;
• gas flow rate max - 0.76 kg / h;
• weight - 5.5 kg.

This gas heat gun can be used from a gas main or with a connected cylinder, in places where there is a power connection and without electricity. Similar advantages have the product Sturm GH91101 with a capacity of 10 kW; with flow rate 0.75 kg / h, capacity up to 330 m³/ h, and the cost is only 5590 rubles.

Experts strongly advise users to repair gas heat guns only in special centers,where there is a master gas equipment, in order to avoid causing irreparable damage to self-service.

Best-selling models

There are many models of gas cannons on the modern Russian market: Master, Ballu and many others, but we will consider only the most popular ones.

Master BLP 10M

Compact gun with a capacity of 10 kW, its speed is up to 300 cubic meters / h, and the consumption is more than modest - 0.75 kg / h. The single-phase connection, the mass of the installation is only 4 kg, it uses liquefied propane, it costs from 4.7 thousand rubles.

BLP 53M

This model has a performance of 1450m³/ h Her power with small dimensions impressive - 5300 W, and gas consumption - 3780 g / h. Therefore, its price is much higher - 10 thousand rubles. It is used for heating large shopping centers, supermarkets and industrial premises: repair shops, factory and factory workshops.

Ballu BHG-20 S

This is a representative of the middle class in the price category, can work on propane and butane, heating rate - 500 cu. m / h, gas consumption - 1.2 kg / h, power - 18 kW, weight - 4.9 kg, and the price of 5 thousand rubles.

All the models presented above use a piezoelectric element for gas ignition and are included in the 10 most popular models.The master is a US brand, but the country of origin today is Italy, and Ballu is a domestic development. For clarity, I advise you to watch a video about the functionality of Ballou:

Connection and operation

Before you turn on the device, you need to read the instructions, where all the nuances of connection and use are described very intelligibly. It is necessary to pay special attention to situations when cannot turn on the device:

• with increased dust content in the air mass of the room;
• if there are vapors of explosive substances;
• the outlet is closed by something.

Operating rules and safety measures may be different from manufacturers of different models - study the attached documentation before proceeding to work.

Gas heat guns are very economical compact products, characterized by high volume heating rate and efficiency, therefore, they are considered by gas equipment experts to be an ideal option for heating various areas of large volume. I would like to note that the Russian heat guns in terms of technical characteristics are not inferior to foreign brands, and their design is almost identical, so there is no point in overpaying.
