Air Source Heat Pumps (ASHPs) absorb heat from the outside air. This heat can then be used to heat radiators, underfloor heating systems, or warm air convectors and hot water in your home.

Different from a Ground Source Heat Pump, an Air Source Heat Pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can get heat from the air even when the temperature is as low as -15°C.

Heat pumps have some impact on the environment as they need electricity to run, but the heat they extract from the ground, air, or water is constantly being renewed naturally.

How do Air Source Heat Pumps work?

Heat from the air is absorbed at low temperature into a fluid. This fluid then passes through a compressor where its temperature is increased, and transfers its higher temperature heat to the heating and hot water circuits of the house.

Is your home appropriately insulated?
For the heating system to be effective, it is essential that you ensure your home is well insulated. The heat pump will provide you with the best efficiency when producing heat at a lower temperature than traditional boilers.

What is the fuel that you are planning to replace?
According to the Energy Saving Trust, the savings are now greater for gas system replacement  than oil. Air Source Heat Pumps work best when replacing gas, oil or LPG as they run off a wet heating system. More savings can be made if replacing electric or coal but the pipework and radiators may need replacing.

What is your desired heating system?
Air Source Heat Pumps perform best with correctly sized radiators and underfloor heating, but our consultants will advise you on this during your call. They are not right for every property and we pride ourselves with providing honest and correct information.
