The heat pump device which pumps heat from a hot reservoir located at a low temperature sink (usually air or water) which is located at a higher temperature of either by the use of mechanical work or with the aid of a hot tank very high temperature.
DC inverter heat pump is one of the best heat pumps for house heating so far, with advanced DC inverter technology, saving 40% electricity than normal on/off heat pump in practical operation. The whole system is optimized with variable fan speed, while the temperature compensation function contributes to a more comfortable indoor environment. It can work with solar, boiler or electric heater according to practical condition of the heating system.
