Ground Source Heat Pumps

WHAT IS GROUND SOURCE?

A Ground Source Heat Pump uses a length of looping pipes buried in a garden to pump a special fluid that absorbs warmth from the ground. This heat then passes through a compressor to make it hotter, then passes to the heat exchanger to heat your water. The cooled fluid returns through the pipes again to create a continual flow of energy and heat.

The temperature under-ground is usually constant throughout the year, however, the length of the pipe required will all depend on the size of property and its energy requirements. Longer loops will draw more heat but in turn requires more space to be buried.


WHY CHOOSE GROUND SOURCE?

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

If you are replacing conventional electrical heating with a Ground Source system you will find that your bills will be lower and you can potentially benefit from the Government’s Renewable Heat Incentive 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 Ground 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) £410 to £595 £2,610 to  £3,940 2,000 to 3,000 kg
Electric (old storage heaters) £830 to £1,465 7,100 to 12,000 kg
Oil older (non-condensing) £475 to £725 3,000 to 4,500 kg
LPG older (non-condensing) £1,315 to £1,975 2,700 to 4,100 kg
Coal £645 to £1,045 7,500 to 11,600 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.
