Cost-Effective Air Source & Ground Source Heat Pump Systems

A heat pump is a device that provides heat energy from a source of heat to a destination called a “heat sink”.

Heat Pumps are an ideal heating solution for many properties; from flats and small houses, to large detached houses and commercial properties and provide a low cost heating system which is supported by the renewable heat incentive.

Space heating and hot water account for nearly three quarters of all energy consumed by the average UK home. Heating your property using a heat pump is now a viable and credible alternative to traditional fossil fuel-based methods and can help you combat rising energy bills. A heat pump will also future-proof your property against rising heating prices as well as future government legislation to tackle the effects of climate change.

The two main versions of heat pump installed by The Greener Group are: ground source and air source. There is also a third type of heat pump, the solar assisted (sometimes called a thermodynamic heat pump)


Whilst heat pumps do require electricity to operate, for every 1kW of electricity consumed you can expect around 3X the amount in heat to be delivered – of which an estimated 70% will be renewable energy. As the energy supplied by the grid becomes cleaner, so too will your new heat pump. Or you can install a renewable energy system (such as solar PV) to generate the energy to power your heat pump for a totally green solution.

Heat Pumps are ideal for off-gas areas as they only require electricity to operate. Plus maintenance is far easier than gas, oil, LPG or biomass – and a professionally maintained system can last for 15 – 20 years. The Domestic RHI lasts 7 years, which is more than enough time for your system to pay for itself and earn you a profit.

The Renewable Heat Incentive (RHI) pays you for every unit of heat energy generated by your renewable heating system. This has been designed to help level the playing field between the cost of renewable and fossil fuel systems. Once you join you stay on the same tariff rate for the next 7 years (only adjusting to bring it in-line with the Retail Price Index). If you’d like to get an idea of how much money you could earn and save through an installation, the Department for Energy and Climate Change (DECC) has launched an online RHI calculator.
