Air Source Heat Pumps

A Warmer Home for Less

Air source heat pumps are an alternative heating system to conventional gas or oil boilers. They are units which are installed outside a property which use thermal energy from the outside air to provide heating and hot water for a building. Air source heat pumps are a low-carbon, renewable technology. They offer incredibly high efficiencies which can significantly reduce the cost of your energy bill.

The air source heat pump in monoblock design achieves high flow temperatures of up to 70 °C – at outside temperatures as low as –15 °C. This makes it especially suitable for modernizing existing buildings.

Since the Heat Pump pulls air from outside, no storage areas for fuel are required. With a lifespan of 10+ years.

Air Source Heat Pump
1
Outside air is blown over a network of tubes in the evaporator which are filled with a refrigerant. This warms up the refrigerant, and it turns from a liquid to a gas
2
This gas passes from the evaporator through a compressor, which increases the pressure. Compression also adds more heat - similar to how the air hose warms up when you top up the air pressure in your tyres.
3
The compressed, hot gases pass into a condenser, surrounded by cool air or water, making it warm. This is circulated around your home to provide heating and hot water. Meanwhile, the refrigerant condenses back into a cool liquid and starts the cycle all over again.
