Yes, because all our heat pump systems are designed for the design temperature. However, there are some differences between the various heat pump systems that need to be considered:
Air-to-water heat pumps:
Air-to-water heat pumps have a lower operating limit of approx. -25°C. For heating systems, this means that the heat output is guaranteed up to the design temperature (in the midlands, for example, at -7°C outside temperature). If the outside temperature drops below this design temperature for one or more days, the auxiliary heating switches on automatically. Statistically, however, this case occurs only very rarely.
Brine-to-water heat pumps:
With these heat pumps, the correct dimensioning of the geothermal probes is important. The heat at depth is constant and changes only minimally, even if the upper layer of the earth is frozen.
