What is biomass and biomass boilers?
Biomass is biological material obtained from living or recently living plant matter that can be processed into electricity, fuel and heat. The materials used are also obtained from sustainable forestry and forestry residues, residual agricultural products, such as straw, sunflower seed husks and peanut husks, and purpose grown energy crops. Biomass is carbon neutral due to the requirement of biomass fuel to be obtained from sustainable sources, an example would be a forest that is replanted, and you maybe even be able to use fuel found on your own land.
How does it work?
Its very simple, taking wood as the most common example, the wood is manually or automatically fed into an auger, set alight and the heat produced is transferred to a water store that then feeds the heating system or taps, it really is that simple. The boiler does of course have cleaver controls that ensure perfect combustion, along with a range of safety devices but in principle it’s extremely simple
Savings and payments (RHI)
Savings on energy bills can be as much as half but is dependent on the existing system and fuel type. There is also a government incentive called the Renewable Heat Incentive ( RHI) that provides a fixed payment for every unit of heat produced. With these payments and the savings you will make on energy bills payback can be as little as 3 years.
