Biomass replaces LPG for school heating
As part of its drive to improve sustainability and reduce carbon emissions, Stroud School in Hampshire has installed two Hoval biomass boilers. They provide space heating and domestic hot water for the main building and two new buildings. The school had previously used LPG boilers.
Operations manager Keith Goldie explains, ‘Rather than introduce more LPG for the new buildings, we decided to look for a more sustainable solution. Having considered a number of options, we chose biomass as particularly suitable for a rural location while enabling the school to take advantage of the Renewable Heat Incentive.’
Consulting engineers Henderson Green specified two 160 kW BioLyt biomass boilers and two 4000 l buffer vessels, also from Hoval. They have been installed in newly created plant rooms in the stable block. An external silo stores locally sourced wood pellets.
Craig Beisley of Accolade Building Services, which installed the boilers, explains, ‘The boilers are linked to a new underground district-heating network that supplies LTHW at 80°C to the new buildings and the main building, High Wood House.
‘In the new buildings, the network provides underfloor heating and DHW via heat-interface units.
‘In Highwood House, plate heat exchangers provide space heating and DHW via an indirect cylinder.’
