Commercial Biomass

A commercial biomass boiler is a very environmentally friendly, safe and convenient way of heating an office block, a farm, hotel or other large building that is off-grid (no natural gas supply). These boilers burn wood pellets, chips or logs to provide warmth in a single room or can power your main heating system and/or hot water.

The Renewable Heat Incentive (RHI) is available for all commercial biomass boiler installations and is now available for domestic properties. The RHI forms part of the government’s Green Deal which was launched in 2013.

Key benefits of Commercial Biomass:


Affordable heating fuel. Although the price of wood fuel can vary considerably, it is often cheaper than other heating options especially fossil fuels.

Financial support. Commercial biomass systems could benefit from the RHI (see example below).

A low-carbon option. The carbon dioxide emitted when wood is burned is the same amount that was absorbed over the months and years that the plant was growing. The process is sustainable as long as new plants continue to grow in place of those used for the fuel.

There are some carbon emissions caused by the cultivation, manufacture and transportation of the fuel. However, as long as the fuel is sourced locally, these are much lower than the emissions produced from fossil fuels.

Financial example of the RHI payment scheme for commercial biomass:


A biomass boiler rated at 36 kWth operates for 7 hours per day in winter and 3 hours per day in summer, i.e. 1,825 hours in total over the year.

This size of boiler is classified as ‘small biomass’. It therefore receives the tier 1 tariff of 8.6p per kWh for the initial 1,314 hours and the tier 2 tariff of 2.2p per kWh for the remaining 511 hours.

*1314 x 36 x £0.086= £4068.14.

*511 x 36 x £0.022= £404.71.
