Air Source Heat Pumps

Air Source Heat Pumps are stand-alone units, roughly the same size as an air conditioning unit. They can be placed outside your home or business premises so no digging or underground pipework is required.

About

An Air Source Heat Pump draws in heat from the air outside and then transfers this heat to provide you with your heating needs by distributing it via underfloor heating and/or radiators.

The great thing with air source is even when the outside temperature is below zero, 100% of your heating and hot water demand can be generated.

A heat pump will keep your home at the temperature you decide, 24 hours a day, 365 days a year no matter the weather. It can also reduce your heating bills by up to 50%.

Nearly all Air Source Heat Pump installations are covered under the UK Government’s Renewable Heat Incentive Scheme so you can earn an extra income too. Contact us today to find our if you’re eligible.

How They Work

Air Source Heat Pumps are incredibly efficient as they move energy rather than create it.  For every 3-3.5kW of heat moved into your home it only uses 1kW of electricity – which is an efficiency  of 300-350%

A fan draws air over a heat exchanger (a copper coil filled with refrigerant like the radiator in your car) in order to extract its heat.

The Air Source Heat Pump’s evaporator then uses the air source heat obtained by the exchanger to boil the refrigerant. The act of boiling turns the refrigerant into vapour which is then transferred to the Compressor.

The Compressor then compresses the vapour and as its volume decreases, its temperature increases. The gas that is created by this is fed through to a heat exchanger, which then transfers the temperature to the central heating water. Forcing this hot gas through the expansion valve condenses the refrigerant back into a liquid.
