Overview
Ground source heat pumps use solar energy naturally stored in soil, bedrock and groundwater as a heat source. They do require electricity to operate, but efficiently produce up to five times as much heat energy, for every unit of electricity they use and are available for a variety of buildings and heating requirements.

Benefits
- Ground Source Heat Pumps are extremely energy efficient - they operate at 225% efficiency when heating domestic hot water (compared to 100% for electric immersion heaters and 85% for gas boilers)
- They are designed to achieve 400% efficiency with radiators and underfloor heating systems
- A typical unit can save up to 2 tonnes of CO2 per year
- A typical unit can save up to 2 tonnes of CO2 per year
Am I eligible?
There are a number of types of Ground Source Heat Pump available to suit the heating requirements of any building, whether it new build or existing property.
The space available for the heat pump is a major factor in the implementation of this product and consideration needs to be taken into the most suitable form of Ground Source Heat Pump.
Bore Hole Collector - is fed into a bore hole to a depth of between 50 and 200 meters but takes up a smaller span underground
Horizontal Collector - Lengths of Pipe loops are buried underground to a depth of around 1 or 2 meters.
Planning permission for the installation of a ground source heating system is generally not required. However, the same may not necessarily be true if you live in a Conservation Area or Listed Building. It is suggested the the planning offices are consulted before installation.
Other considerations include:
- They can be used with radiators but work better with underfloor heating systems because they operate at a lower temperature.
- You should ensure the building is properly insulated to ensure maximum efficiency.
Funding and Grants
Phase 1 (available from July 2011) - RENEWABLE HEAT INCENTIVE (RHI) Premium Payment.
This is called the "RHI Premium Payment" and will be worth around £15m and available to 25,000 householders in Great Britain who install from July 2011.
The exact amounts available to consumers have yet to be confirmed. However the Department of Energy and Climate Change (DECC) have announced that the following amounts may be available:
RHI is designed to provide financial support that encourages individuals, communities and businesses to switch from using fossil fuel for heating, to renewables such as wood fuel.
- Solar Thermal - £300/unit
- Air to Water Source Heat Pumps - £850/unit
- Biomass boilers - £950/unit
- Ground Source Heat Pumps - £1,250/unit.
These are one off payments; so not annual. DECC plan to publish details of the "RHI Premium Payment" and how this will apply in May this year though recipients of this payment will need to ensure that:
- They have a well-insulated home based on its energy performance certificate;
- They agree to give feedback on how the equipment performs.
Further guidance will appear shortly once announced.
Phase 2 (available from October 2012) - RENEWABLE HEAT INCENTIVE
People in receipt of the Renewable Heat Premium Payments will be able to receive long term RHI tariff support once these tariffs are introduced, as will anybody who has installed an eligible technology since 15th July 2009.
These tariff payments will start alongside the Green Deal from October 2012 to allow a more whole-house approach to heat production and energy saving.
RHI is designed to provide financial support that encourages individuals, communities and businesses to switch from using fossil fuel for heating, to renewables such as wood fuel.
