Ground Source Heat Pumps

Ground source heat pumps use pipes buried in a field or garden, or a borehole, to extract heat from the ground. This is usually used to warm water for radiators or underfloor heating systems. Beneath the surface, the ground stays at a constant temperature, so a ground source heat pump is efficient throughout the year even in the middle of winter.

Benefits of ground source heat pumps are;

  • Provides 100% of your heating and hot water requirements
  • Save space: the indoor unit for a ground source heat pump system is compact, and requires no storage space for fuel.
  • Eliminate your fossil fuel bills: ground source heat pumps run on a small amount of electricity, so there’s no need to pay for increasingly expensive gas, oil or solid fuels to heat your building
  • Reduce your CO2 emissions: Ground source heat pumps have significantly lower CO2 emissions than traditional fossil fuel heating systems due to their high efficiencies: up to a 43% saving in CO2 over gas and a 57% saving over oil.
  • Cut down on wasted electricity: heating your home with a ground source heat pump is much more efficient than using electric radiators.
  • Highly efficient. a typical ground source heat pump has a COP of up to 4.6 (up to 460% efficient). So for every kw of energy you put in, it will generate up to 4.6 kw of heat.

How does a ground source heat pump work?

A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe - called a ground loop - which is buried in the field or garden. When the liquid travels around the loop it absorbs heat from the ground - used to heat radiators, underfloor heating systems and even hot water.

The length of the ground loop depends on the size of your building and the amount of heat you need - longer loops can draw more heat from the ground.

Normally the loop is laid flat, or coiled in trenches about 1-2 metres deep, but if there is not enough space in your field/garden you can install a vertical loop to a depth of up to 100 metres (borehole).

The efficiency of a ground source heat pump is measured by a coefficient of performance (CoP) - the amount of heat it produces compared to the amount of electricity needed to run it. A typical CoP for a ground source heat pump is between 3.2 and 4.6 (320%-460% efficient)

Fuel Savings

The costs of running a heatpump, when installed into an efficient building, is much lower than oil or LPG, look at a comparison of fuel costs, ongoing heating and hot water costs are therefore much lower than conventional systems

Renewable Heat Incentive

A heatpump installation will qualify for either the domestic RHI or non domestic RHI. The RHI is a government incentive paying you for every unit of heat generated by your eligible system. You can learn more about the RHI here

Other Incentives

For both domestic and commercial clients there are a number of other applicable incentives available here
