Is it suitable for my home?

You should consider the following issues if you're thinking about installing a ground source heat pump.

• You will need space outside your house for the ground loop.
• The ground will need to be suitable for digging a trench or borehole.
• What fuel is being replaced? If it's electricity, oil, LPG or coal the payback will be more favourable than gas. Heat pumps are a good option where gas is unavailable.
• The type of heat distribution system. Ground source heat pumps can be combined with radiators but these will normally be larger than with standard boiler systems. Under floor heating is better as it works at a lower temperature.
• Want to be 100% renewable? Buy green electricity, or install solar PV or some other form of renewable electricity generating system to power the compressor and pump.
• Is the system for a new building development? Combining the installation with other building works can reduce costs.
• Have you installed insulation measures? Wall, floor and loft insulation will lower your heat demand and make the system more effective.
