Ground Source Heat Pump – Call to Discuss Your Options
Heat your home with completely green energy from the ground!
Futureplumb are eco-friendly and determined to save you money, that’s why we are providing you with information about all the different kinds of renewable energy that is on offer. Ground source is where extract heat from the ground by using pipes that are buried in the garden. This heat can be used to heat radiator, underfloor or warm air heating systems and provides hot water for your home.
A ground source heat pump circulates a mixture of water and antifreeze around a pipe, called a ground loop, which is buried in your garden. Heat from the ground is absorbed into the fluid and passes through a heat exchanger into the heat pump. The ground stays at a fairly constant temperature under the surface, so the heat pump can be used throughout the year – even in the middle of winter. Obviously, the more garden space you have, the more energy your home will be provided with.
We have listed below why we think ground source heat pumps are great:
- could lower your fuel bills, especially if you replace conventional electric heating
- could provide you with an income through the government’s Renewable Heat Incentive (RHI)
- could lower your home’s carbon emissions, depending on which fuel you are replacing.
- you don’t need fuel deliveries
- it can heat your home and provide hot water
- it needs very little maintenance – they’re called ‘fit and forget’ technology.
Most people are suitable for a ground source heat pump. You don’t need a particularly big garden, but it needs to be suitable for digging a trench. Your home will also need to be well insulated for the heating system to be effective. The system is also most effective if you are replacing electricity or a coal heating system. Heat pumps may not be the best option for homes using mains gas.
Costs and savings. Installing a typical system costs around £11,000 to £15,000. Running costs depend on the size of your home and how well insulated it is. Below is a table showing the amount of savings you might make every year when replacing an existing heating system in an average four-bedroom detached home with an average GSHP installation:
|Existing system||Savings per year||RHI income per year|
|Gas older (non-condensing)||£/year||£395 to £590||£2,325 to £3,690|
|Carbon dioxide/year||1.8 to 2.9 tonnes|
|Electric (old storage heaters)||£/year||£650 to £1,215||£2,325 to £3,690|
|Carbon dioxide/year||6.2 to 11.1 tonnes|
|Oil older (non-condensing)||£/year||£650 to £1,035||£2,325 to £3,690|
|Carbon dioxide/year||2.6 to 4.2 tonnes|
|LPG older (non-condensing)||£/year||£1,265 to £2,000||£2,325 to £3,690|
|Carbon dioxide/year||2.5 to 4.0 tonnes|
|Coal||£/year||£575 to £990||£2,325 to £3,690|
|Carbon dioxide/year||6.8 to 11.1 tonnes|

Don’t forget you may be able to recieve payments and may be able to get help with the installation costs from the government’s Renewable Heat Incentive (RHI) for the heat you generate.
