AIR SOURCE HEAT PUMPS
Air source heat pumps absorb heat from the outside air, generating electricity to heat radiators and hot water in your home.
As a recommended installer of Mitsubishi Ecodan air source heat pumps, you can benefit from our approved installer status and over five years’ renewable experience. Whether it’s a no obligation telephone discussion or a scheduled home visit, we can help reduce your carbon footprint.
Air source heat pumps work on the same basic principles as a refrigerator but in reverse, taking heat from the air compressing it and converting it into usable heat for the home.
A heat pump typically consists of four main components:
- Expansion valve
How it works
1.In an air source heat pump, outside air is drawn over the evaporator. The refrigerant absorbs heat from the air and changes from a liquid to a vapour.
2.The refrigerant then passes through a compressor, increasing the pressure and consequently the temperature of the vapour. This higher temperature is now suitable for domestic heating
3.The higher temperature refrigerant then passes through the condenser heat exchanger, transferring heat to the heating system. With the heat now removed, the refrigerant returns to liquid. The liquid refrigerant then passes through the expansion valve, returning the refrigerant to its original state ready to repeat the cycle. A heat pump typically consists of four main components; evaporator, compressor, condenser and expansion valve.
GROUND SOURCE HEAT PUMPS
A ground source heat pump draws heat from the ground around the dwelling by circulating fluid through a slinky (shown in the trench below). The heat is then magnified by pressuring the refrigerant before it is delivered to the living space via radiators and/or under floor heating systems.
A ground source heat pump is ideal for properties with adjacent land including large gardens, and is suitable for well insulated homes using under floor heating or low temperature heating systems.
Ground source heat pumps are capable of producing four times more heat energy than the electrical energy they use during operation. This offers significant carbon savings over conventional electrical heating systems.
