Highly efficient domestic water heating pump for sustainable, resource-saving domestic water heating The x-change fresh heat pump uses the air (room, extract, or outside air) to heat domestic water. It has a storage capacity of 258 litres and can generate up to 850 litres of hot water in 24 hours. The water is heated up to 62 °C. It is an ideal addition to a solar panel system. Due to the Power-to-Heat principle, part of the self-generated electricity can be used economically to operate the x-change fresh for supplying hot water. The highly efficient domestic water heat pump with a COP value of 2.98 (A15/W55) is ideally for this operating mode.
