Wood fuelled (or biomass) heating systems generally burn wood pellets, chips or logs to power central heating and hot water boilers, or to provide warmth in a single room. There are two main ways of using wood to heat your home:
Log burning stoves and boilers have to be filled with wood by hand. Some pellet and chip burners use automatic fuel feeders which fill them, as required, from fuel storage units called hoppers.
There are many benefits to using a wood fuel system
Is a wood fuelled system suitable for my home?
Wood costs often depend on the distance from your home to the wood supplier and weather you can buy and store wood in large quantities. If you have your own supply then this can significantly reduce your costs, but you will need a place to dry the wood properly before use.
Costs for a 'stand alone' pellet stove are around £4,500 including installation. A typical automatically fed pellet boiler for an average home costs about £11,000 including istallation, fuel store and VAT at 5%.
Savings in CO2 emissions for wood systems are significant - up to 9.5 tonnes per year when a wood boiler repalces a solid (coal) fired syatem or electric storage heating.
Biomass case studies still to be added
