Bedfordshire School installs energy efficient boiler

22nd Nov 2012


Students and teachers at Marston Vale Middle School are enjoying the benefits of renewable energy after a new boiler system was installed

Previously the school was heated by two 20 year old boilers but it is now one of the first schools in the county to install energy efficient biomass boilers. It has already installed solar panels which enabled it to benefit from the Feed-in Tariff  and the biomass boilers will now enable the school to take advantage of the Renewable Heat Incentive (RHI) as well.

“Pupils at Marston Vale Middle School learn about the importance of conserving the earth’s natural resources” said Director of Asgard Biomass Ross Donovan. “It is inspiring for them to be part of a school that demonstrates a real commitment to renewable energy.”

The RHI will allow the school to earn 8.3 pence for every kilowatt of energy the boilers produce. The building will generate an estimated income of between £10,000 and £18,000 from the RHI each year for the next 20 years with an additional 28 percent saving through the use of biomass pellets rather than oil.

Installing a biomass boiler at a school not only helps it to save energy but also provides important curriculum benefits by helping the students to learn about renewable energy. Biomass boilers however do tend to be larger than their fossil fuel equivalents, which means that more space is needed including storage space for fuel. Wood chip and wood pellet boilers can be fed with fuel automatically from the fuel store using an auger screw system. A regulated flow of oxygen helps to ensure that the fuel is burnt efficiently and the resulting gases heat water in a heat exchanger. This then feeds the hot water storage tank and the heating system itself, which usually consists of radiators. Heating controls allow all users to adjust the system for specific needs and some boilers can be operated remotely via text messaging.
