Biomass - Wood-fuelled heating systems, also called biomass systems, burn wood pellets, chips or logs to provide warmth in a single room or to power central heating and hot water boilers.
A stove burns logs or pellets to heat a single room - and may be fitted with a back boiler to provide water heating as well. A boiler burns logs, pellets or chips, and is connected to a central heating and hot water system. A wood-fuelled biomass boiler could save you up to £880 a year compared to electric heating.
A biomass pellet stove will cost around £4,300 including installation. Installing a new log stove will usually cost less than half this, including a new flue or chimney lining.
For boilers, an automatically fed pellet boiler for an average home costs between £9,000 and £21,000, including installation, flue, fuel store and VAT. Manually fed log boiler systems can be slightly cheaper.
Pellet costs depend mainly on the size and method of delivery. If you have room for a large fuel store that will accept several tonnes of pellets at a time, delivered in bulk by tanker, you can keep the cost down to around £230 per tonne in most parts of the UK.
Logs can be cheaper than pellets, but costs depend on the wood suppliers in your local area, as they cost a lot to transport. If you have room to store more than a year’s worth of logs you can save money by buying unseasoned logs and letting them season for a year.
Savings in carbon dioxide emissions are very significant - up to 15.4 tonnes a year - when a wood-fuelled boiler replaces a solid (coal) fired system or electric storage heating. Financial savings are more variable - if you replace an older gas heating system with a wood-burning system you might save up to £70 a year, but if you are replacing an old electric heating system you could save as much as £880 per year.
