Much like a refrigerator working in reverse, the energy in the outside air is removed and absorbed by the refrigeration circuit, compressed to form a superheated gas and then transferred via a heat exchanger into renewable hot water . This hot water is then stored in a thermal cylinder and used for DHW or heating. High COP values of 1 to 3 - its extremely efficient and for every 1 kw it can generate over 3 kw of electricity, achieving super energy savings. The resultant waste by-product of this heat transfer process “cold air” is then extracted to atmosphere. once complete the cycle repeats itself
