Log/Pellet/Woodchip

How do Biomass Boiler systems work?

Heating rooms using open fires may look good but is very inefficient as most of the heat goes up the chimney and as the fire draws in oxygen to burn, it creates draughts in the room that can cancel out the benefit of the heat. Modern wood- burning stoves are a huge improvement on the open fire for room heating. They convert up to 90% of the fuel into useful heat. If you attach a back boiler, they can also help heat water and radiators or under floor heating systems. By burning logs, wood chips, wood pellets or other forms of biomass, the most advanced boilers are fully automatic controlling the amount of fuel and air supplied to the combustion chamber. As a result they are highly efficient and emissions are low. Fed with wood chips or pellets from a large hopper, maintenance becomes minimal – although you will need to clean it and remove the ash about once a month.

- Woodchips are currently the cheapest form of heating fuel according to the Biomass Energy Centre

- The Renewable Heat Premium Payments offer a grant of £950 to help with the upfront costs of installing a biomass boiler (see Grants and Incentives)

- Biomass heating systems are permitted developments unless the flue exceeds the height of the roof by one metre or more.
