The energy source of infrared heaters can be either mains or LPG.Gas infrared heaters designed for heating large spaces, so they are unlikely to be useful in a normal apartment. Most likely they will appreciate the owners of cottages and country houses, because the power produced to date models of gas infrared heaters only starts from 1.5 kW. In addition to the power cost when choosing to pay attention to the type of heating (direct and indirect). In the direct type of heating the air required for the burner comes from the heated space, and the products of combustion go back into the room. Therefore, when installing gas heaters with direct heating of the room must be equipped with an efficient ventilation system. Indirect heating system is provided in the heater outlet gas, but it requires skill to install.Plus, gas infrared heaters use provides independence from the mains.
The recommended distance is largely dependent on the capacity of the heater. For power 700-800 Tues permissible location of the unit at a distance of 0.7 meters. If the boundaries of the heater power are in the range 1-1.5 kW, it is recommended to keep away from him at least a meter. The subtlety is that the distance is measured from the surface of the infrared heater to the human head. Therefore, if the radiator with a heating power of 700 W is possible to install almost anywhere in the home or office space with a ceiling height of 2.5 m, with a capacity of twice the installation must be properly thought through. This may be a point on the workplace in the office or over the bed in the bedroom.
