~ NerG to supply a new biomass boiler system for Wightwick Manor ~

Biomass boiler specialist NerG has been commissioned to deliver a 200 kW biomass boiler system for the National Trust at Wightwick Manor, a Victorian manor house located in Wolverhampton, England. The system will heat the entire site, including the manor, shop and café, and will provide carbon savings of about 85 tonnes per year, a reduction of 90 per cent.

Until recently, Wightwick Manor was heated using two ageing and inefficient natural gas boilers. Not only were these becoming increasingly difficult to maintain, but this dependence on natural gas also left the site vulnerable to increased energy costs caused by the volatile nature of natural gas prices — something that is of growing concern after recent events saw a surge in prices and gas shortages across the UK. This is concerning to the National Trust since any future lack of heating could impact conservation at the historic property.

Following a competitive tender process, the National Trust chose to work with NerG to install a new heating system at the site. It had previously worked with the company at its Belton House site where NerG delivered one of the National Trust’s largest biomass district heating schemes to date.

“The National Trust is aiming to produce at least 50 per cent of its energy from renewables moving forward, so it made perfect sense for it to opt for a biomass system to replace the ageing natural gas boilers at Wightwick Manor,” explained Luke Worrall, business development manager at NerG. “The 200 kW biomass capacity that we are delivering for Wightwick Manor is made up of two Froling P4 100 kW boilers that use wood pellets as fuel. These will be more than capable of heating the entire site and deliver carbon savings of approximately 90 per cent.”

The project also includes an extension of the heating system in the café to open a new area, allowing more indoor seating. Overall, the project involves installing around 100 metres of underground district heating pipework. Because Wightwick Manor is a listed historical property, the system has been designed to be installed as sensitively as possible and minimise any impact on structures.

“The system will be installed into the stables and the design accounts for all existing structures in them, leaving historic feed troughs in place and touching as little of the structure as possible to mitigate any impact. In essence, the project helps put renewable energy at the heart of conservation and shows that these technologies can be made to work in some of the country’s most sensitive historical settings,” added Worrall.

The contract for Wightwick Manor also includes a service plan for NerG to carry out annual boiler servicing and flue cleaning, helping to keep the system operating at peak performance across its lifespan. Work began in September 2021 and the system is due to be commissioned in December 2021.
