Biomass has been heating our homes for thousands of years in the form of wood fires. New highly efficient biomass boilers are not only a greener alternative to gas, oil and electricity, they can also offer significant reductions in fuel costs over these systems.
These systems are already used widely in mainland Europe (40% of Austria’s energy comes from biomass sources) and domestic biomass boilers are a very popular energy solution in Scandinavian countries.
How do Biomass Boilers work?
They are similar to traditional wood burning stoves but work to a high degree of efficiency. On a traditional wood burner a lot of energy is lost through the chimney and to the surrounding air. Modern stoves can convert over 90% of the fuel used into useful heat for your home.
Wood can be fed into the boiler in the form of logs, pellets or chips and are burnt in the combustion chamber to efficiently produce heat. This heat is then released into a heat exchanger to provide heat through a wet central heating system. This can also be used to provide domestic hot water.
