Wood Fuel
2003 Identified potential for biomass boilers utilising local wood fuel (Council arboriculturalwaste)
2006 1st Bristol biomass boiler installed.
No wood fuel supplier so self supply required
Blaise Nursery biomass boiler and wood fuel station
Secondary school and PFI schools – helping to meet green credentials

Butler House
150kW biomass boiler supplying zero Carbon heat to elderly resident block Scheme operational and working
extremely well from Day 1
RHI complaint saving minimum of 10% of heating bills to residents
Housing Delivery very happy with working installation with no tenant complaints from fuel deliveries etc
Fully ECO funded – allows RHI to be used to fund higher pellet prices over Gas, + helping to reduce fuel poverty
