Heat Pumps Sat advanced heating system for the propulsion, electrical power, but due to a complex method of heating a much cheaper, more energy efficient and environmentally friendly than using conventional electric heaters.
trick of heat pumps is that they do not convert electricity directly into heat, but it used to drive the compressor, which in turn draws heat from the cooler ambient and emitted into space. Such a system may be operating from one unit of electricity are also obtained up to 4 units of heat.
reason for the relatively small prevalence of such a method of heating lies in the relatively high initial investment, which you usually can afford only investors in larger buildings, where the investment is repaid quickly itself.
