Viessmann supports Defra’s RHI emissions levels

Viessmann has responded to the Department for Environment, Food and Rural Affairs’ update on RHI biomass emissions levels.

Viessmann sales director for commercial and renewable products Nigel Jefferson has stated that the company supports Defra’s RHI emission levels.

In a statement, he said: “In an update on the Renewable Heat Incentive (RHI) and Clean Air Act issued on Thursday June 7, Defra confirmed that plans published in a paper in August 2011 by Defra, DECC and Ofgem are being taken forward.

“The paper proposed that support under the RHI is restricted to boilers capable of complying with limits of 30g/GJ particulate matter and 150g/GJ nitrogen oxides.

“Viessmann supports this anticipated amendment and is in favour of even stricter proposed EU emissions levels. Installers and end-users should adopt clean technologies such as cyclonic combustion and Lambda controls which are already available and exceeding the new targets.

“The biomass industry has a great future, helped by the introduction of the RHI. Particularly with regard to public sector policy, many new build and refurbishment projects must now consider the use of wood-burning heating.

“However, the industry should take heed of concern, backed up by various studies, into the projected environmental impact of biomass boilers and the effects on human mortality in built-up areas.

“It must respond by providing the cleanest, most advanced technology, if it is to avoid harming the long term reputation of biomass as a suitable renewable heating option.

“Many forward-thinking boiler manufacturers are already producing boilers that meet the tighter, emerging UK emissions regulations and which even comply with tougher upcoming EU regulations, expected to be 20 mg/MJ for dust.”
