Biomass boilers deliver heat, and RHI payments, to Stroud School – and connect to heat network


Stroud School Romsey BioLyts_1Stroud School in Hampshire has installed Hoval biomass boilers to provide space heating and domestic hot water for the main school building and two new buildings. Installation of the new plant and an associated district heating network was carried out by Accolade Building Services.

The school’s recent expansion included the construction of two new stand-alone buildings – a classroom pod and resource room, plus a dining room and kitchen.

“We were using LPG boilers and rather than introduce more LPG for the new buildings we decided to look for a more sustainable solution,” said the school’s operations manager Keith Goldie. “We chose biomass as being particularly suitable for a rural location while enabling us to take advantage of the Renewable Heat Incentive. It is also something we can use to help educate children about the alternatives to fossil fuels,” he added.

Specified by consulting engineers Henderson Green, the two 160 kW BioLyt biomass boilers, along with two 4000 litre buffer vessels also supplied by Hoval, have been installed in newly created plant rooms in the stable block. The boilers are served by an external silo storing locally sourced wood pellets.

Craig Beisley of Accolade Building Services explained: “The boilers are linked to a new underground district heating network which supplies low temperature hot water at 80°C to both of the new buildings and also to the main building, Highwood House. In the new buildings the network provides underfloor heating and domestic hot water via heat interface units.

In Highwood House plate heat exchangers are used to provide space heating and domestic hot water via an indirect cylinder. The district heating network also incorporates provision for future connections to additional buildings as the school expands. The project was completed on time and within budget and we were very pleased with the support we received from Hoval throughout.”
