New models of HFC based domestic air/water heat pump have been presented, claiming to present the highest possible seasonal performance on the market.
Using R-410A as a working fluid, the heat pump is using a bespoke inverter compressor, increasing energy efficiency and comfort. All component parts within the machine have been optimized, bringing the COP of the largest heat pump to 4.08 with an air temperature of -2 °C.
The heat pumps can deliver water at 65 °C instead of the commonly achieved 50 °C, therefore avoiding anti-legionella specific measures.
