The Renewable Heat Incentive is a grant scheme targeted at renewable heating systems. Biomass boilers, solar thermal, ground and water-source heat pumps are covered but not air source heat pumps.
The RHI is centrally funded, unlike the FIT PV scheme which is funded by additions to utility bills (and so can be viewed as a sort of stealth tax if you were feeling cynical).
If you are a business or part of a community that want to provide heat to a group of houses then Phase I of the RHI is for you. For a biomass boiler you would get a payment of 6.43p per kWh up to a pre-defined ceiling (they call it a "Tier") after which the rate drops. In the calculations I have done recently it would appear that the ceiling is pretty generous and so you would usually expect to stay within the 7.5p/kWh ceiling as long as the system is correctly sized, and run as it should be.
On 9th April 2014, Ofgem opened the domestic renewable heat incentive scheme. For full details of the new dRHI scheme and how it can benefit you, please visit our Renewable Heat Incentive page.
Update: The dRHI is continuing to run so you can still benefit from this grant scheme. Since March 2016, the DECC have removed the requirement of a Green Deal Assessment from the scheme making it simpler and quicker to apply for the dRHI.
MCS certified products have been certified to ensure that they are of a high quality and meet the standards expected when the are to be supported by a government grant scheme. Several Klover wood pellet boilers listed on Stovesonline are MCS certified, as well as several log gasification boilers. Often certification is through the BRE but there are some other equilalent standards, for example the Solar Keymark for solar thermal systems.
Please find a list below of the wood pellet boilers, pellet stoves, and log gasification boilers on our site which are MCS registered.
Biomass boilers over 40kW do not need to be MCS registered so remember this if you are considering a large log gasification boiler.
The DECC (Department of Energy and Climate Change) have launched a Biomass Suppliers List to allow homes and businesses to search for RHI compliant fuel suppliers.
As of Spring 2015, all Biomass heat installations with the RHI grant will have to show that their fuel is from an accredited supplier. If you come under the non-domestic installation, you can choose to self-report in agreement with sustainability criteria.
If you don't get your fuel from an accredited supplier from the Biomass Suppliers List, further RHI payments will cease when the list is enforced from Spring 2015. Visit this website to find you're nearest accredited fuel supplier.
