Biomass boilers generate renewable energy by burning wood to provide heating and hot water, rather than using heating oil, gas or LPG. As a result, biomass boilers tend to be somewhat larger than conventional central heating boilers.
Biomass renewable energy is 50% cheaper than LPG – Biomass boilers are ideal for farms and rural homes which cannot access natural gas because of the relatively high cost of heating oil and LPG, compared to biomass wood pellet fuel.
Using December 2013 prices, biomass energy costs around 4.3 pence per kilowatt hour (kWh), which makes it over 30% cheaper than heating oil (6.4p/kWh) and 50% cheaper than LPG (8.6p/kWh).
Biomass renewable energy heating systems are a mature proven heating technology which has been used extensively in Austria, Denmark and Finland.
The Carbon Trust referred to biomass renewable energy as one of the few “cost effective and practical ways to provide space heating and hot water from a low carbon source”.
Biomass Wood Pellets
Modern condensing biomass boilers are designed to use wood pellets as fuel but in many other respects they operate just like gas and oil-fired boilers.
Biomass fuel wood pellets are fed from an integrated hopper, through an auger (screw type conveyor) into the combustion chamber where they are burned.
This produces hot gases and the heat from these gasses is transferred to water which is distributed around your home’s central heating system and to provide hot water through your taps.
