A biomass system works by burning wood pellets, chips or logs. It can be connected to a central heating and hot water system and generate substantial energy savings when compared to other forms of heating.

The use of biomass in heating systems is beneficial because it uses agricultural, forest, urban and industrial residues and waste to produce heat and electricity with less effect on the environment than fossil fuels. This type of energy production has a limited long-term effect on the environment because the carbon in biomass is part of the natural carbon cycle; while the carbon in fossil fuels is not, and permanently adds carbon to the environment when burned for fuel.

Biomass boilers are particularly useful for organisations who have sizeable heating demands, such as nursing homes, hotels, large commercial units, leisure centres and poultry farms. Installing a system of this kind can bring significant financial savings of between 30% and 50%.
