Biomass Boilers

Biomass boilers burn wooden logs, chips, pellets or other forms of biomass to produce energy to heat water. The hot water can then be used for consumption and heating through traditional radiators, or under floor heating. The boilers are fully automatic and control the amount of fuel and air supplied to the combustion chamber. As a result they are highly efficient with low emissions.

Biomass boilers can be operated using a range of combustible fuels including high-energy crops, industrial waste and agricultural waste, however most systems operate using wood as its primary fuel source.

The most efficient biomass boiler fuel is wood pellet. Wood pellets are made from compressed sawdust and shavings. They contain high energy levels, burn efficiently and produce very little ash. The efficiency of the fuel means many appliances and wood pellets are certified for use in smokeless zones in the UK.

Biomass boilers tend to better suit properties that have the space to accommodate a fuel store to enable the boiler to automatically feed its self. It is recommended that between a 6 and 12-month stock of fuel is maintained, which will require an area of stocking unit of round 7m3 equivalent to most LPG or oil storage vessels. However boilers can also be manually fed with bags of pellets.

Biomass Boilers offer a real sustainable alternative to fossil fuel heating systems. Applying for Government grants can significantly offset installation costs, and once installed operating savings are currently around 50% compared with LPG and 30% compared to heating oil.
