Cold weather in Russia is a common thing, so gas heat guns are used to heat greenhouses, garages, hangars, warehouses, industrial premises. Modern appliances burn blue fuel with virtually no smell and smoke. It is enough to periodically ventilate the room to ensure a comfortable microclimate. Since various security systems and electric fans are installed in gas heat generators, there must be a household network (220 V) in the room. A wide range of gas guns is presented on the domestic market. Recommendations of our experts will help potential buyers to choose the optimal model.
Safety. Gas-fired heat generators have several dangerous points.
- One of the main disadvantages of gas heat guns is the increased fire hazard. If handled carelessly, the gas mixture may explode (a spark in an enclosed space is sufficient). Manufacturers solve this problem by installing valves and a gearbox, and overheating protection.
- The second negative point is the burning of oxygen and the formation of a large amount of carbon dioxide. The room should be well ventilated or a supply and exhaust ventilation system should be installed in it. It is desirable to limit the time spent by people in such a room.
Thermal power. The choice of a heat gun should begin with the calculation of the heat output. Experts advise to adhere to a simple scheme for rooms with a height of 2.5-3 m: for heating 10 square meters. m requires 1 kW of thermal power. But the calculation should take into account the height of the ceilings, the degree of thermal insulation, the temperature difference, the duration of the gun.
Maximum air exchange. Gas heat generators are equipped with electric fans that provide rapid heating of the air. Manufacturers indicate the throughput of their products in cubic meters per hour. However, experts warn of a high outlet temperature for devices with high performance. In the most powerful gas guns, air exchange reaches 2500-3000 cubic meters. m/h
Type of fuel. Modern gas guns operate on different types of blue fuel.
- The most common are models that consume liquefied gas. It can be propane, butane or a mixture of these hydrocarbons. The specific heat of combustion of these gases is approximately the same. Butane burns faster than propane, but has a boiling point of -0.5ºC (propane has -42ºC), which creates problems at low temperatures. Therefore, it is more expedient to fill the cylinder with a propane-butane mixture with a high concentration of propane in winter.
- Natural gas (methane) is rarely used. It is burned in powerful industrial models. To switch to liquefied gas, special jets and burners are required.
Ignition system. To ignite a gas mixture, it is necessary to create a spark or an open flame.
- Manual ignition models require the use of matches or lighters.
- For non-smokers, it is more profitable to use guns with piezo ignition. Ignition occurs when the corresponding button is pressed. In some models, the piezoelectric element is automatically activated when the gas valve is opened.
Fuel consumption. The economic feasibility of using a heat gun depends mainly on gas consumption. Approximately, to release a thermal power of 1 kW, it is necessary to burn 0.07 kg / h of blue fuel (propane-butane mixture). The most economical low-power models consume 0.7-2.5 kg / h. More productive heat generators burn from 3 to 7 kg/h.
We selected 11 gas heat guns for review. All of them are sold in Russian stores. When distributing places, the editors of the journal expertology proceeded from the opinions of experts, taking into account the feedback from domestic consumers.
