Why should you use biomass for your business? a biomass boiler can produce enough energy to provide central heating and hot water for your business, in place of a gas or other boiler, and with the RHI in place the more you burn the more you earn, so no need to cut back on your heating and hot water anymore. On top of that, it’s an excellent alternative to costly fossil fuels. Coupled with low energy costs and excellent financial returns from the commercial RHI, Biomass is a leading renewable source of heat. Biomass can be applied from small offices to large factories.
