Greener technologies such as heat pumps are likely to become increasingly popular thanks to the domestic Renewable Heat Incentive scheme. Launched in April 2014 adopters of renewable heating will receive money for producing green heat.
An air source heat pump works by extracting heat from outside air, just as a fridge does when it extracts heat from its interior. The pumps operate with your existing heat system and cut down carbon emissions.
Even with an outside temperature as low as minus 15° C heat can be obtained.
There are two main types of systems:
• An air to water system utilises your wet central heating system. It works more efficiently at a lower temperature than a standard boiler, making it particularly good for underfloor heating systems or larger radiators. This is due to the low heat release over long periods.
• An air to air system produces warm heat which is then circulated throughout the home by fans.
The pumps work by absorbing heat from the air into a fluid, which is then pumped through a heat exchanger. Alternatively, low heat is passed through a heat pump compressor then concentrated into a higher temperature. It can be used to heat water and the hot water circuits of the house.
The non-residential phase of the Renewable Heat Incentive (RHI) went live back in November 2011, while the domestic side of the scheme was launched on 9 April 2014. This incentive is aimed at everyone, including households, businesses, schools, hospitals and more. It can also be used by entire communities as a joint investment.
Installing an air source heat pump will benefit the homeowner in much the same way much as the Feed-In Tariff (a comparable scheme for electricity) does. Thanks to the RHI users of air-to-water heap pumps get paid 7.3p/kWh.
Furthermore, using air source heat pumps can help cut household heating bills by up to 70 per cent. Heat pumps are also 100 per cent proven technology, meaning there are no risks.
More reasons to switch
In the UK heat production is responsible for around half (49 per cent) of the total energy demand consumed. Almost half of all the UK’s carbon emissions are produced as a result. By switching from fossil fuels to cleaner and more sustainable sources of energy homeowners can reduce the impact that our heat requirements have on the environment and will take advantage of an energy supply that is safe, secure and reliable.
Air source heat pump prices
It will cost between £6,000 and £10,000 to install an air source heat pump. How much it will cost to run your heat pump will be influenced by various important factors, not least the size of your home and how well it is insulated.
