Using a standard geothermal ground loop, our high-temperature hot water heat pump (WC Series) delivers up to 160°F (70°C) hot water for high-temperature hydronic heating systems. We accomplished this by using a two-step system involving two refrigerant circuits and two compressors.
This heat pump would be ideally suited for homes retrofitting from hot water boilers, with hot water baseboard or hot water radiators. This heat pump could also be used as a stand-alone system for heating domestic hot water.
Nordic High-Temperature Hot Water Heat Pump
Our cascading water to water heat pump is available in sizes up to 6.5 nominal tons, for whole home heating applications.
