Condensing biomass boilers get RHI boost

Condensing biomass boilers will be eligible for the domestic Renewable Heat Incentive (RHI), when it launches in spring.

The government has performed a U-turn over the technology, which was not part of the RHI policy when it was released in July 2013 because of fears over certain pollutants discharged from such boilers.

The concerns surrounded polycyclic aromatic hydrocarbons (PAHs) – which are categorised as priority hazardous substances by the EU – and their impact on water quality.

Research by Defra has now revealed that a small amount of PAHs is released in the condensate from condensing biomass boilers, but the levels are too low to pose a significant threat to the environment, and water treatment ensures the risk of aquatic PAH pollution is minimal.

Simon Allan, Plumb Center’s renewables director, said: “At Plumb and Parts Center we’re delighted with the news that condensing biomass boilers will be included in the domestic RHI.

“This move provides great business opportunities for installers, and gives people more options when looking for ways to heat their homes safely, cleanly and efficiently.

“Installers who want to find out more about condensing biomass boilers will be able to at Ecobuild 2014. We’ll have a demonstration model at our Practical Installer Arena, so pop along to see how the technology works, and the benefits it can have for your customers.”
