The ETHERMA AQUA WHP hot water heat pump guarantees efficient water heating in both new builds and modernization projects. It is equally suitable for use in new and existing buildings. It is ideal for applications where the room air needs to be cooled, for example in a food storage room or a wine cellar. It can use either recirculated air or outside air. As a recirculating air heat pump, AQUA WHP uses the air directly from the room in which it is installed. Heat is extracted from the room air, which the heat pump uses to heat the domestic hot water in the storage tank to up to 62 °C. The cooling of the room air also removes moisture from the room. This protects the building fabric and improves the quality of living. With the outside air adapter and connected air ducts, the heat pump can easily be switched to outside air operation. This is particularly important in new buildings with good thermal insulation to prevent the building from cooling down. The heat pump works efficiently down to an outside air temperature of -5 °C. Capacity: 178 or 254 l, DHW temperature: 65 °C (62 °C with PV system), operating pressure: max. 10 bar, color: white, refrigerant: R1234-ze(E), energy efficiency class: A+, 230 V.
