WHAT IS AIR SOURCE?

Essentially, Air Source Heat Pumps use heat from the outside air to either heat your water for your taps or central heating, or you can use it to warm air convectors.

air-source-heat-pump2Similar to the way a fridge extracts heat from its inside, an Air Source Heat Pump extracts heat from the outside air which is absorbed into a fluid and passed through a compressor which increases the heat. This heat is then transferred to the to the hot water/heating pipes of the property. Amazingly this technology can even extract heat when the temperature is -15C outside.

They do require electricity to run, so can be a good form of technology to use when a property has Solar PV and/or Battery Storage technology.

Heat pumps produce heat at lower temperatures and radiators will not be as hot as those run from biomass, oil or conventional gas boilers, therefore Air Source pumps need to run over longer periods of time and in the winter may need to run on a continual basis to maintain an ambient temperature.

There are two type of Air Source functions:

Air to Water – which uses your wet central heating system.

Air to Air – which produces and circulates warm air to heat a home.


WHY CHOOSE AIR SOURCE?

An Air Source Heat Pump is an efficient and low maintenance way to heat your hot water and run your heating all year round.

It’s a cheaper alternative to many some other heating sources as there is no requirement for fuel deliveries or storage and it’s easy to install.

If you are replacing conventional electrical heating with an Air Source system you will find that your bills will be lower and you can potentially benefit from the Government’s that will provide a regular payment for using this renewable technology.

Taken from the Energy Savings Trust here is a table of the potential fuel savings and RHI benefit that are achievable by replacing a system with Air Source technology, based on a four bedroom detached house.

Existing system Fuel bill savings (£/year) Renewable Heat Incentive (RHI) payment (£/year)
1 Jan 2016 to 31 Mar 2016
Carbon dioxide savings (kgCO2/year)
Gas older (non-condensing) £295 to £425 £905 to £1,365 1,600 to 2,400 kg
Electric (old storage heaters) £715 to £1,295 6,700 to 11,400 kg
Oil older (non-condensing) £360 to £555 2,500 to 3,900 kg
LPG older (non-condensing) £1,200 to £1,805 2,300 to 3,500 kg
Coal £525 to £875 7,100 to 11,000 kg

RHI PAYMENTS?

The domestic Renewable Heat Incentive (RHI) was designed by the Government to encourage households to switch to a greener, renewable method of generating heat. Although Air Source Heat Pumps require electricity to work, they use naturally renewed heat from the air.
