Ground source heat pumps are an exceptionally carbon-efficient technology that can replace your current heating system and may dramatically reduce your heating costs. Ground source heat pumps are Renewable Heat Incentive eligible products.
How a ground source heat pump could benefit you
Ground source heat pumps are extremely efficient and much cheaper to run than traditional heating systems. You will be generating your own heat using just a small amount of electricity and taking free geothermal heat from the ground.
Protection from rising energy costs
Energy costs are anticipated to rise considerably in the next few years - you can protect yourself against rising costs by producing your own heat from a renewable source.
Get paid for the heat you generate
With the UK Government's Renewable Heat Incentive scheme, you will be paid for all of the heat your air source heat pump generates. Renewable Heat Incentive payments are made to you quarterly for 7 years and are tax-free and increase in line with inflation. The Renewable Heat Incentive ensures your system pays for itself in typically under 7 years.
Preserves the environment
Switching to renewable energy helps to reduce pollution, lessen our dependence on finite fuels and reduce your CO2 emissions.
Heat pumps eliminate the need to have fuel delivered to your property and you won't need to worry about running out of fuel. This makes air source heat pumps a much more convenient renewable option than a biomass boiler.
An air source heat pump can convert 1 kilowatt of electricity into 2.5 kilowatts of heat, by taking 1.5 kilowatts of electricity from the air. For comparison, an A-rated combined boiler can only turn 1 kilowatt of gas or oil into 0.9 kilowatts of heat.
Anticipated Return on Investment over 20 years for a previous installation
Figures are based on the generation of 18,000 kWh of heat and presume a ground source heat pump with a 35° floor temperature using underfloor heating. Initial outlay of £30,000 (including excavation work) - read more here
How they work
Ground source heat pumps extract heat from the ground and concentrate it for use in a property. This is possible even when the weather is cold, as even cold ground contains plenty of usable geothermal energy. In the UK, the year round ground temperature is a fairly steady 6-12 degrees Celsius.
To extract heat, a mixture of water and anti-freeze is circulated through a buried pipe. This part of the system, called a ground loop, can be laid horizontally or vertically dependent on the site. The fluid in the loop absorbs low-level heat from the ground and carries it to the heat pump for use in the home.
Heat pumps need a relatively small amount of electricity to convert heat from the environment into usable heat. Ground source heat pumps can effectively turn 1 kilowatt of electricity into 3 kilowatts of "free" heat from the ground. This is compared to an A-rated combined boiler, which turns 1 kilowatt of gas or oil into 0.9 kilowatts of heat.
