Ground Source Heat Pumps
Ground source heat pumps extract heat from pipes buried in the ground. This can be used to heat conventional radiators or under floor heating systems and hot water. The ground stays at a fairly constant temperature beneath the surface, so a ground source heat pump can be used throughout the year.
The earth itself ‘stores' energy therefore it is an extremely reliable and constant energy source, it creates no harmful emissions and uses a very small amount of electricity to drive the pumps themselves.
The energy consumption for heating and hot water can be lowered by up to 75% with a ground source heat pump in comparison to heating systems using fossil fuels.
Is a ground source heat pump suitable for my home?
To tell if a ground source heat pump is right for you, there are a few key questions to consider:
Q. Is your garden suitable for a ground loop?
A. It doesn't have to be particularly large, but the ground needs to be suitable for digging a trench or a borehole and accessible to digging machinery.
Q. Is your home well insulated?
A. Since ground source heat pumps produce a lower temperature heat than traditional boilers, it's essential that your home is insulated and draught proofed well for the heating system to be effective. It could also make the system cheaper and smaller.
Q. What fuel will you be replacing?
A. If you're replacing an electric, or coal heating system, a ground source heating system will save you more on your heating bills. Heat pumps are not recommended for homes on the gas network.
Q. What type of heating system will you use?
A. Underfloor heating systems, larger radiators or low temperature fan convectors (warm air heating) can perform better than standard radiator-based systems because of the lower water temperatures required.
Q. Is the system intended for a new development?
A. Combining the installation with other building work can reduce the cost of installing the system.
