Biomass Installations Wood Pellet / Log Stoves As all trees grow they absorb carbon that is in the surrounding atmosphere. The carbon is then released through the combustion of the wood and re-absorbed by other trees; this cycle renders the combustion of wood for heating purposes as carbon neutral. The use of wood pellets/logs will therefore reduce CO2 emissions.  Replacing your existing fire (gas/coal) with a wood pellet/log burning stove as the secondary heating system would replace the fossil fuel (harmful to the atmosphere) with a carbon neutral heat source. If you don't already have a secondary heat source, adding a wood pellet/log stove would reduce the work load of the primary heating system. Currently, the SEI's Greener Homes Scheme Grant covers €1,100 towards the cost of a wood pellet/log burning stove. Pellets (bagged) currently cost 6.4 c/kWh compared to solid-multifuel at 3.4 c/kWh; however carbon emissions and energy consumption are reduced dramatically with the more efficient pellet/log burning stove. The price of wood pellets is also falling as the market improves, while the price of fossil fuels is currently on the rise. If a wood pellet boiler is already installed, the stove could use bulk pellets which are cheaper at about 3.4 c/kWh. Wood Pellet Boiler Installing a wood pellet boiler instead of a new gas or oil boiler reduces the heating efficiency to around 65%, having an affect on your house's energy rating. However, as the boiler runs on low-carbon wood pellets it greatly reduces your building's carbon emissions. Wood pellets bought in bulk cost around 3.4 c/kWh with no standing charge, compared with natural gas at around 4.5 c/kWh, with €307/year standing charge or heating oil at 6.4 c/kWh. However, these fuel savings must be offset against the increased cost of installing a wood pellet boiler system, which is partially offset by the €4,200 grant available in the Government's Greener Homes Scheme. | ||||||||||||||||||||||||||||||||||||||||
