Condensing Biomass Boilers Now Qualify for the Domestic Renewable Heat Incentive

Government analysis has shown that certain pollutants discharged from condensing biomass boilers are minimal. This is why these types of boilers will be eligible for the domestic Renewable Heat Incentive Scheme. The Renewable Heat Incentive (RHI) is the world’s first long-term financial support programme for renewable heat. The government launched RHI in November 2011 with a scheme for the non-domestic sector that provides payments to industry, businesses and public sector organisations.

Launching in the spring of 2014, condensing biomass boilers will qualify for the renewable heat incentive, providing that they meet all other eligible criteria of the scheme. Condensing biomass boilers were not previously eligible for the domestic RHI when the policy was published in July of this year. They were not eligible because there were concerns about PAHs (polycyclic aromatic hydrocarbons). PAHs are potent atmospheric pollutants. Some compounds have been identified as carcinogenic, mutagenic and teratogenic. The concern boiled down to the fact that it was believed the PAHs could have a negative impact on the quality of water.

But it was found by the Department for Environment, Food and Rural Affairs that there were only very small amounts of PAHs which were released into the condensate from the condensing biomass boilers. Therefore it was concluded the condensing biomass boilers would not actually pose a significant threat to the environment and the risk of the pollutants were minimal.

The RHI pay participants of the scheme who generate and use renewable energy to heat their buildings. The RHI is helping the UK to reduce greenhouse gas emissions and meet targets for reducing the effects of climate change by increasing the generation of heat from renewable energy sources.

The scheme is planned to open in spring 2014, the Renewable Heat Premium Payment Scheme has been extended for a further year to March 2014 to provide continued support for households until the domestic RHI is introduced. Condensing biomass boilers being included in the domestic RHI will give people more options when looking for ways to heat their homes safely, cleanly and efficiently.
