Electric heat guns are powerful fans for heating of various rooms: warehouses, shops, garages, rooms and so on. Also they are used for drying and ventilation of rooms.
Instruction
1. Choose what heat gun you want: stationary or mobile. For installation of the stationary gun installation works are required, and for work with the mobile heat gun it is enough to read the instruction.
2. Choose type of the heat gun: rectangular or cylindrical. Squared guns are generally equipped with special heaters in the form of grid. Such guns are suitable for warming up of internal rooms better.
3. Models of cylindricity are equipped with heating coil in the form of spiral. Such guns at the exit give big temperature that well is suitable for heating of the area in the open air.
4. Choose type of heating of air: direct and indirect. Heat guns of indirect heating will be suitable for room heating in which constantly there are people and animals. In such heaters there is exhaust system.
5. In heatgenerators of direct heating there is no gas withdrawal system. Their use is recommended, for example, for drying of rooms when carrying out repair work.
6. Define what power to you needs the electric heat gun. With it you can be helped by special formula of calculation of power of the heat gun. For calculation you need to know: V - the volume of the warmed room in cubic meters, T - temperature difference between the required temperature indoors and out of it in degrees Celsius, K - dispersion coefficient. The coefficient of dispersion or thermal loss depends on structure of the building and level of heatlosses of walls which can be learned from the special table. Having multiplied three of these indicators, you receive value of necessary thermal power in kilocalories per hour. For determination of necessary power of the heat gun in kilowatts divide the received digit into 860 as 1 kW = 860 kcal.
