GMO Solar Heat Pump Water Heater makes use of the heat in the ambient air around the system, and a reverse refrigeration process to heat the water. This means the sun doesn’t need to be shining, and whats more, it is so efficient that it can provide reliable hot water 24 hours a day, even in temperatures as low as -10℃ with no booster element. 1. Sun Heats the Air.Heat pumps rely on ambient air temperature rather than incidental sunshine. Utilising refrigeration principles, GMO Heat Pump can extract heat from the air without the need for direct sunlight, and can produce hot water in rain, hail or shine without the need for a booster element. 2. Energised air inducted into heat pump. Once the air is drawn into the heat pump, it passed over an evaporator containing a refrigerant which boils at a very low temparature. The boiling refrigerant is then compressed causing its temperature to be raised even futher transforming it into a super-heated vapour. 3. Energy transferrred to heat cold water. Using GMO tank wrap technology, this super-heated vapour is fed through copper coils(condenser) wrapped around the outside of the water tank, heating the water evenly and efficiently from the outside in. 4. Cold air expelled. Once the heat has been extracted from the air and transferred to the water, the remaining cold air is discharged from the heat pump by fan. Once the desired water temperature is reached, the system will go into energy-saving standby mode until it is required to commence heating again.
