AIR SOURCE HEAT PUMPS

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

A better way to heat your home

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 radiators.

The best thing is that even when the outside temperature is below zero, 100% of your heating and hot water needs can be generated.

A heat pump will keep your home at the temperature you decide, 24 hours a day, 365 days a year...AND reduce your heating bills by up to 50%. Its all about you and what you want.

So how do Air Source Heat Pumps work?

Air Source Heat Pumps are clever little things and incredibly efficient as they move energy rather than create it so for every 2.5kW of heat moved into your home it only uses 1kW of electricity which is a performance efficiency of 250%!

How it actually works sounds more complicated than it is so hopefully this step by step guide will ease you through using an Air Source Heat Pump:

A fan simply forces air over a heat exchanger (a copper coil filled with refrigerant) 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 (boils at approximately -10˚C) and the act of boiling turns the refrigerant into vapour which is then transferred to the Compressor.

The Compressor then literally compresses the vapour and as its volume decreases, its temperature increases and the gas that is created by this is fed through to a heat exchanger within the heating pump.

Forcing this hot gas through the central heating system’s cold water condenses the refrigerant back into a liquid but as it does this its heat is passed into the heat exchanger which supplies your domestic hot water and powers the central heating system using the air source heat extracted originally.

To complete the Air Source Heat Pump’s closed circuit, the pressure of the condensed liquid is reduced via the expansion valve and ‘Voila’ – your heating requirements are provided!
