Biomass boilers offer an environmentally sound, heating solution. Burning biomass, such as wood pellets or logs, emits the same amount of carbon dioxide as is absorbed while the plants were growing. Therefore, biomass is classed as carbon-neutral renewable energy.

Biomass boilers burn biomass fuels extremely efficiently and use the heat produced to provide heating and hot water. They can also be more cost effective and efficient than fossil fuel boilers, especially in rural or off mains gas areas.

Types of Biomass Fuel

Biomass is defined as biological material that has come from plant matter. It produces heat by burning the organic material. Although there are many forms of biomass, the most commonly used for small scale household installations is untreated and unfinished wood, including bark. This comprises wood chips, logs and sawdust, often from furniture manufacturing, formed into wood pellets and briquettes for use in biomass boilers and stoves.

Other sources of biomass material include high yield energy crops, such as wheat, that are grown specifically for energy applications.
