Biomass Domestic Back Boilers

Biomass Domestic Back Boilers


For domestic heating purposes the main biomass fuel is wood in the form of logs, pellets or wood chips, although some boilers also burn a range of cereals.


Smaller biomass stoves can be used just for room heating, with a back boiler to heat the water, or to produce hot water and heating for the whole house.


Is a biomass boiler suitable for my home?


Wood burning stoves are suitable for heating any room that has a chimney or a flue. They come in many shapes and sizes, and can burn logs, or wood pellets. The wood pellet stoves tend to be cleaner and easier to maintain, producing much less ash. However, some people find the noise of the fans on these stoves annoying, so research before you buy.


If you are in a smokeless zone KM Renewable Energy can provide appliances that burn the wood so cleanly that they are certified for use in smokeless zones.


Biomass boilers tend to be larger than the equivalent gas or oil boiler. They are generally more suitable for people not connected to mains gas who have  some space for fuel storage.  For an average size house you will need about 6-7 cubic metres of space near where the boiler is sited to store the fuel.


Ideally the fuel storage area will be under cover.  It is important to keep fuel dry as a high moisture content will reduce the efficiency with which it burns. Wet wood pellets are unusable.  The fuel store needs to be accessible for a delivery lorry. Wood pellets can be delivered loose and blown into a hopper, or supplied in bags on a pallet.
