Drinking water heat pump x-change® fresh
Highly efficient drinking water heat pump for sustainable, resource-saving domestic water heating.

The x-change fresh heat pump uses the air (room, exhaust or outside air) to heat the drinking water. The cylinder capacity is 258 litres and can produce up to 850 litres of hot water in 24 hours. The water is heated to up to 62 °C in the process. It is the ideal complement to a photovoltaic system. This is because part of the self-generated electricity can be used to operate the x-change fresh using the power-to-heat principle. With a COP value of 2.98 (A15/W55), the highly efficient drinking water heat pump is optimised for this operating mode.
