Biomass Boiler Maintenance

Biomass boilers like other boilers should be serviced regularly by a qualified service engineer.

The biggest difference with biomass boilers is the requirement to dispose of ash that builds up as part of the combustion process.  Wood combustion produces 0.5-1.5% by weight of ash, depending on fuel quality. This ash collects in an ash pan under the grate. It has to be removed manually at periodic intervals depending on the heating demand. Automatic de-ash systems put the ash into an ash bin, reducing the amount of work required. However, the ash bin still requires emptying periodically.  The ash can then be used as a wood fertilizer
