Biomass boilers - What is this type of heating?


Biomass boilers are an environmentally friendly heating solution that provides heating and hot water. They are ideal for households that aren’t connected to mains gas and have additional space for fuel storage.

Biomass boilers produce what is classed as carbon-neutral renewable energy, meaning their use is less harmful to the environment than other types of boiler that rely on gas and oil. 

Fuelled by biological materials that are derived from plant matter, the most commonly used fuel for residential biomass boilers is untreated and unfinished wood, compressed into pellets.

Other biomass fuels can include animal, food and industrial waste and high-energy cereals such as rape and maize.


How does a biomass boiler work?


To generate heat and hot water, wood pellets are placed into a chamber where an electric probe ignites them. A microprocessor then monitors the combustion via thermostats in the flue gasses, and as a result automatic adjustments are made to the fuel supply and the fan speed.

Hot flue gasses are passed through a heat exchanger, so that heat is transferred from the combustion gasses to the water used in the central heating system.


What are the advantages of biomass boilers?


  • Energy efficient
  • Reduced carbon dioxide emissions
  • No need for a tank or cylinder
