Biomass boiler systems operate in the same way as a conventional boiler system, with the exception of fuel delivery. Pellets or wood chips are fed through an auger which is automatically controlled by the boiler. As the fuel enters the boiler, the material is ignited either by elements or an electric blower on the initial start-up. The hot gases are then passed through a heat exchanger and the heat is transferred to the water used in your central heating system.


Savings in carbon dioxide emissions are very significant – around 7.5 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 a gas heating system with a biomass system you might save £100 a year, but if you are replacing electric heating you could save as much as £580 a year.


Choosing a wood-fuelled heating system

  • Biomass Boiler?
    Boilers can be used in place of a standard gas or oil boiler to heat radiators for a whole house, and to heat the hot water.
  • Chips, pellets or logs?
    Chips are not suitable for heating a single house if you are short of space, but can show greater savings compared to pellets. They are best used in larger buildings or groups of houses. Pellets are much easier to use and much more controllable than logs; pellet boilers can run automatically in much the same way that gas or oil boilers operate. Log-burning stoves and boilers have to be filled with wood by hand; most pellet and chip burners use automatic fuel feeders which refill them at regular intervals. Logs require considerably more work, and you will need a lot of logs to heat a whole house, but they can be cheaper than pellets if you have a good local supply.
  • Do you have space?
    Wood boilers are larger than gas or oil equivalents. You will also need space to store the fuel: somewhere that’s handy for deliveries but also appropriate for feeding the boiler.
