Air/water heat pumps

Air/water heat pumps draw energy from the ambient air. They suck in the outside air and make the warmth stored through compression available for heating purposes. After use, the cooled air is discharged back into the external environment. Air/water heat pumps work efficiently with external air at a temperature as low as -20 °C.

Instead of a ground probe, a well, or a plot of land, air/water heat pumps only require one installation location for the outdoor unit. An air/water heat pump is designed either as a single block with only one outdoor unit or as a multi-block system. A multi-block system consists of an outdoor and an indoor unit.

Air/water heat pumps don’t require retrofitting or separate areas. They are therefore ideally suited for modernising existing heating installations and properties with hard to access land. Systems with air/water heat pumps can be expanded easily, for example, with solar panels and condensing boilers. Air/water heat pumps are the cheapest option to purchase, but their power output is comparably low.
