The benefits of ground source heat pumps
You can benefit in many ways from fitting a ground source heat pump and exactly what you are able to earn or save will be dependent on your circumstances, however you could benefit by over £600 per year.
- Reduce your carbon footprint: Heat pumps can lower your home’s carbon emissions, depending on which fuel you are replacing, because they reduce the fuel that you need to burn for heating.
- Reduce your heating costs: This is especially true if you are currently using conventional electric heating. Heat pumps provide space heating and hot water more efficiently than traditional heating sources, saving you money on your bills.
- No fuel deliveries required: By replacing your oil or solid fuel heating system you are removing the need to have fuel deliveries. All that is required is electricity to power the pump.
- 'fit and forget’: Heat pumps are often classed as a ‘fit and forget’ technology because they need little maintenance.
Getting paid for producing heat
You will be able make money out of the heat you produce through the Renewable Heat Incentive scheme, details of which will be released in 2013. Learn about the Renewable Heat Incentive and RHPP here.
An example created by the Energy Saving Trust shows that a typical domestic electrical system could earn around:
- £610 per year reduction in current electricity heating bills
- A single Renewable Heat Premium Payment of £1,250
- A regular payment from the Renewable Heat Incentive – to be confirmed in 2013
What to do next?
- Can a ground source heat pump be used with underfloor heating?
- Underfloor heating is a great choice for use with a ground source heat pump, but large radiators or a mix of both can be used for distributing heat around your home. Heat pumps produce a lower temperature heat than conventional boilers, therefore they are far more effective if used with a larger surface heating distribution system such as underfloor heating or large radiators. A good rule of thumb is that if used with heat pumps, the radiators should be around 30% larger compared to the size of radiator that would be used with a conventional boiler.
- Will a ground source heat pump be able to heat my home adequately in the winter?
- As long as you have enough space in your garden for a system that meets your needs, and your choice of system is suited to your heating needs, a ground source heat pump should be able to heat your home comfortably in the winter. They are often used very effectively in far colder countries than Britain.
- Will a ground source heat pump provide enough hot water for heating and baths/showers?
- Yes, with the correct design and equipment, a ground source heat pump can meet all your domestic hot water requirements throughout the year. If you do not have enough space in your garden for a system large enough to meets your needs you can top up the heat the heat pump produces with the help of a more conventional system. Your installer will be able to confirm whether the size of system you can accommodate will meet your needs.
- Will a ground source heat pump save me money on my energy bills?
- Yes, a well designed ground source heat pump system will save money and CO2 compared to other traditional heating systems, especially now that the government is in part funding new installations with the Renewable Heat Premium Payment grant. Exactly how much money you save depends on how well your system is designed and the efficiency of your old system. Find out how much you could save by completing our Energy Assessment.
