Heat Pumps…. What are they all about?

Heat pumps essentially take over the role of your current central heating and hot water source, the difference being they are 3 – 4 times more energy efficient and only use a small amount of electricity to run instead of Gas, Oil or LPG that your existing system may use. Heat pumps can be used to both heat and cool an area

Both GSHP and ASHP may seem complex but that couldn’t be further from the truth they are fairly simple bits of kit that once installed can supply your home or business with years’ worth of cheap uninterrupted heating and hot water.

I get paid by the Government to have a Heat Pump installed? Are you sure?


The Renewable Heat Incentive ( RHI ) is a UK Government scheme set up to encourage the uptake of renewable heat technology.

The RHI has different rates for ASHP and GSHP but both are paid every quarter over a 7 year period.  GSHP payment can total £29,442 over the 7 year period. The RHI is exempt from income tax so no tax is paid on any payment received from the scheme it is also index linked so rises with inflation. A solid investment by anybody’s standard!

Ok well, how do Heat Pumps work ?

Both GSHP and ASHP operate on the same basic principle – Heat Transfer.  This means that rather than burning fuel i.e. Gas, Oil the heat pump moves heat from one place to another. In the case of GSHP it moves heat naturally stored deep in the ground into your home via your normal radiators or underfloor heating. Its exactly the same with ASHP only this transfers the smallest amount of heat from the air and boosts its temperature  to heat your home. ASHP can pull heat out the air with temperatures outside as low as -20 degrees.

Air Source Heat Pumps

ASHP’s look like air conditioning units and sit either on the external wall or floor of your house.

ASHP’s are less disruptive to install than GSHP as there is no digging to be done in your garden, they are also cheaper to install than GSHP.

Ground Source Heat Pumps

GSHP’s look like a fridge size unit with controls and displays on the front, it can be situated in or around the house in external garages / shed

GSHP take the heat from the ground, this can be done in 2 ways. Trenches or boreholes.

Trenches are 1meter deep channels dug into your garden or adjoining land. These trenches are used to burry the ground array. The ground array is essentially the pipework used to extract the heat from the ground. Using this tequunique there needs to be a fair amount of land and access for diggers to the property, trenches are the cheapest option out of the two.

Boreholes are 100-150 meter deep holes drilled into the earth, the holes are used for the pipework to go into and extract the ambient heat from the ground. This tequnique needs very minimal space and can be done in most gardens with  little mess. This is the more expensive option due to the machinery needed to drill the holes

Both Trenches and bore holes are organised and managed by upgrade and Save to ensure all heat calculations are met
