Air Source Heat Pumps extract heat from the outside air and transfer that heat into your central heating and hot water system.
All year round it keeps your home cosy and warm and your hot water reliable for total comfort and piece of mind.
Heat pumps work in a very similar way to conventional refrigerators just in reverse.
An evaporator collects heat from the ambient air, even at temperatures as low as -20°C.
The evaporator contains liquid refrigerant and the heat transfers from the air to the refrigerant.
This process increases the temperature of the refrigerant changing it from a liquid to a gas. The refrigerant gas is then compressed by an electrically driven compressor. This causes its temperature to increase significantly.
The hot gas is then passed through a condenser, where the heat energy is transferred to the water used in the household heating system.
Finally the cooled refrigerant turns back into a liquid, after passing through an expansion valve, it returns to the evaporator and the process starts again.
