Air-to-water heat pump can achieve 65°C
Panasonic’s Aquarea HT series of air-to-water heat pumps deliver hot water at 65°C, suiting them as a high-efficiency retrofit replacement for gas boilers supplying radiators for heating. A patented refrigeration cycle and flow control have been combined with a high-efficiency inverter and heat-exchange module to give outstanding energy performance. The 9 kW model can achieve a COP of 4.55.
These units can deliver hot water at 65°C right down to an ambient of -15°C. They are very quiet in operation as there is no double-stage compression. The refrigerant is R407C, which works at higher temperatures than R410A, so hot water can be produced at 65°C with only one stage of compression.
There are models with heat outputs of 9 and 12 kW, single- and 3-phase, in bi-block and mono-bloc versions.
