Biomass heating systems generate heat from biomass (wood waste, pellet, briquettes or wood chips).
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 (carbon footprint). Historically, before the use of fossil fuels in significant quantities, biomass in the form of wood fuel provided most of humanity’s heating.
Heating with biomass can lead to significant annual cost savings, particularly for users that have high heat usage requirements. The cost of heat generated by logs, wood chips, or wood pellets is significantly lower than the cost of heat generated by oil, gas, or electricity: with increasing world demand for fossil fuels, it is likely that this gap will increase further, even after accounting for possible price increases on wood fuel.
