A biomass boiler has been installed in the school of 365 pupils to provide hot water and heating that uses carbon neutral wood pellets supplied from a local source.

Additional water heating is provided by solar thermal panels and there is a gas condensing boiler for backup.

The 350kW heating system at Weobley Primary School and meets the base load of the primary school as well as the adjacent secondary school.An oil fired boiler in the secondary school provides back-up and peak power.

During most weather conditions the biomass boiler is sufficient to heat both schools without the need for back up. The primary school is fitted with underfloor heating and has a maximum design heating load of 115kW.

The school receives around 300 tonnes of locally grown wood chip each year. The woodchip is stored in a concrete silo with a hydraulically controlled lid, large enough to receive twice weekly deliveries.

The biomass heating system cost £120,000 to buy and install with grant funding (£79,000) obtained from the European EAGGF programme.
