Lower your energy bills with a ground source heat pump
Ground source heat pumps use pipes which are buried in the garden to extract heat from the ground. This heat can then be used as part of your central heating, underfloor heating or water system.
The length of buried pipe depends on the size of your home and the amount of heat you need. Longer pipes can draw more heat from the ground, but need more space to be buried in. If space is limited, a vertical borehole can be drilled instead.
- Lower your fuel bills.
- Income through the government’s Renewable Heat Incentive (RHI) scheme.
- Lower your carbon emissions.
- No fuel deliveries needed.
- Can heat your home as well as your water.
- Minimal maintenance required.
Is a ground source heat pump suitable for me?
To tell if an air source heat pump is right for you, there are a few key questions to consider:
- Is your garden suitable for a ground loop? It doesn’t have to be particularly big, but the ground needs to be suitable for digging a trench or a borehole and accessible to digging machinery.
- Is your home well insulated? Since ground source heat pumps work best when producing heat at a lower temperature than traditional boilers, it’s essential that your home is well insulated and draught-proofed for the heating system to be effective.
- What fuel will you be replacing? The system will pay for itself much more quickly if it’s replacing an electricity or coal heating system. Heat pumps may not be the best option for homes using mains gas.
- What type of heating system will you use? Ground source heat pumps can perform better with underfloor heating systems or warm air heating than with radiator-based systems because of the lower water temperatures required.
- Is the system intended for a new development? Combining the installation with other building work can reduce the cost of installing the system.
