Currently, air-to-water heat pumps are in high demand, which, thanks to the high coefficient of heat conversion, reduce energy consumption and negative impact on the environment. The advantages of using a heat pump are safety, environmental friendliness, economy, and the fact that when using it, dependence on rising prices for natural energy sources is reduced. One of the main problems of the air-to-water heat pump is a decrease in productivity when the outside air temperature drops in winter. This paper analyzed the efficiency of air-to-water heat pump Mitsubishi Electric PUHZ-SHW230YKAR1 for providing a private house with heating, hot water supply and air conditioning. On the basis of the obtained results, graphs of the efficiency of the heat pump were constructed depending on the temperature of the environment and the coolant. The installation is able to generate heat at an external temperature of minus 28°C. The maximum heating temperature of the coolant is 60°C.
