Ground Source Heat Pumps
Pipes concealed in the ground extract the heat in the earth allowing the ground source heat pump (GSHP) to distribute it around your home via radiators, underfloor and hot water systems. Working on a similar method to a refrigerator a ground source heat pump circulates antifreeze in the pipe work, absorbing heat into the liquid in a continuous process, therefore raising the temperature in order to deliver all the warmth necessary for domestic dwellings.
As the ground stays at a constant temperature, the heat pump can be in operation all year round. This may be costly you may ask, however, heat pumps deliver heat at lower temperatures over a longer period of time. This is a more efficient way than gas or oil boilers which switch on and off accordingly.
The sum of heat you require for the size of your property determines the length of the ground loops, but if space is scarce bore holes can be drilled vertically into the ground. The loop system is laid flat in trenches roughly 1.4m deep whereas bore holes run to a depth of up to 200m for a domestic property. Heat pumps do require electricity to work but this doesn’t exceed the benefits.
BENEFITS OF GROUND SOURCE HEAT PUMPS
- Could lower your fuel bills, particularly if you replace conventional electric heating
- Could provide you with a financial incentive through the government’s Renewable Heat Incentive (RHI)
- Could lower home carbon emissions, depending on which fuel you are replacing
- No fuel deliveries needed
- Can provide you with all of your heating and hot water requirements
- Minimal maintenance required
