Quite often in separate rooms there is no additional heating, which is needed in the Russian winter. To always be warm, you can use this unit as a heat gun. Buy it quite simply, it sold in almost any construction or specialty stores. Particularly often such devices are used in garages or stables with livestock, but depending on the size and power of the gun, it is used for construction, heating, factory floors and other large indoor area. Heat guns, in turn, are of three types: diesel, gas and electric. Before you opt out of these types, you need to realistically assess gun operating conditions. For example, do not forget that electric heat gun, it has low power rates compared to other heating devices (3 to 30 kW), but not for large rooms rational use of one – two guns, then need to calculate power. Electric guns are considered the most economical among other species, but also because of the peculiarities of the wiring and electrical fire Gun is ideal for heating offices and other small enclosed spaces.
Diesel gun, perhaps, the most powerful among the three species, they run on diesel fuel, the combustion of which generates the energy going obgorite on the premises. Capacity of thermal units is 10 to 250 kW. Gas heat gun, have less power than diesels, it ranges from 10 to 150 kW. They work on gas – butane and propane, sold in individual bottles. This type of gun is quite popular in Russia. Virtually all models of guns equipped with a thermostat, and it greatly enhances the safety and convenience of use.
A certain can be further staffed control systems. So, now knowing the kinds of heat guns, and the approximate cost of implementation, it is necessary to determine the capacity. In the beginning you need to determine the volume (capacity) of premises that needs heating, it is calculated in cubic meters. To calculate this indicator in addition to the coefficient of thermal insulation required facilities and the indoor temperature difference between the temperature of which was to inclusion of a heat gun and the temperature desired. Capacity is usually denoted by the letter V, insulation factor – K, to denote the temperatures can get the T1 and T2. For commercial premises is considered normal temperature 19 degrees, just take it to calculate. We can assume that before the heating temperature is equal to one degree, then T is 20. Volume of the room box of medium size is about 500 cubic meters. Of and these figures we can calculate the result, which will pick up the equipment. In this case, Q will be equal to 25.5 kW, based on already from these figures, it follows that we must take the gun power equal to or greater than this figure. Thus, when choosing a warm gun, is based on its performance and appearance.
