Resource savings: Energy:
They are typically rated from 8 – 500 kW (Carbon Trust, 2008) and achieve efficiencies of 85-90 %
Payback time:
When replacing electric, LPG or heating oil systems, the payback on capital can be rapid (in some cases under 3 years for applications with a high heat load)
Total cost savings:
Biomass fuel typically costs less than the fossil fuel it replaces; savings depend on the price of the fossil fuel being replaced and the cost of the biomass fuel used
Premises and operation areas:
Production building
Size of company:
Micro (less than 10), Small (less than 50), Medium (less than 250)
Advancement in applying resource efficiency measures:
Intermediate
What is in it for you:
Lower pollutant emissions. Variable load demand coverage. High boiler efficiency.
Descriptive information:

Biomass heating systems can be used for space heating in buildings, hot water and production, or any combination of these. The most relevant source of biomass heat for the accommodation sector is wood, and the most efficient conversion pathway is through direct combustion, which can mean burning wood chips or pellets in boilers, or larger pieces in gasifying wood boilers.

Pellet boilers are highly automated and well suited to meeting variable load demands. They typically achieve efficiencies of 85-90 %. Pollutant emissions are lower than for other types of wood boilers owing to precise automated systems and homogenous pellet composition. Indeed, pellet boilers are state-of-the-art for solid biomass combustion alongside gasifying boilers.

Wood chip boilers work on the same principle as pellet boilers, with automated control of chip feed supply. Whilst boiler operation is similar to pellet boilers, the average heating value and homogeneity of wood chips are lower than for pellets, resulting in more variable performance and slightly lower efficiency. Wood chip boilers usually incorporate a fuel stoking system whilst pellet boilers use a simpler pellet metering system and are better suited to larger applications and facilities.

Wood chips are often cheaper than pellets in terms of expected energy output because they require less processing.
