A common misconception about heat pumps is that they can only heat water up to 45oC. However with new compressors and refrigerant gases, heat pumps can now heat water to over 70oC if required. This eliminates any issues with Legionnaires' disease in drinking water and the need for an auxiliary heating system.
Waterkotte heat pumps contain recognised refrigerants that comply with international standards. These refrigerants are approved and recommended by manufacturers of the relevant compressors. The refrigerants used are exclusively new, non-inflammable safety refrigerants, which will be required by law in the future. According to the latest industry research, used together with synthetic oil, they ensure low friction, the very lowest wear and tear, and thus the greatest longevity for the compressor.
The refrigerants used are:
