Water to water Heat pump
The reversible water-water heat pumps (refrigerant side) of the WRK range, for indoor installation, cover a spectrum of heating capacity levels from 38. 9 kW to 165. 9 kW, and a processed water temperature of 65°C. This means they're a valid alternative to traditional boilers for centralised heating systems with high-temperature terminals such as existing radiators, and for the production of domestic hot water. With its steam injection scroll compressor, this circuit ensures that extensive operating limits and very high constant and seasonal efficiency values (ηsH up to 195% with an average water temperature of 55°C) can be reached, so WRK is the perfect solution not only for new constructions but also when the aim is to increase the efficiency of existing systems.
