Biomass boilers burn wood pellets, chips or logs to generate heat to power central heating or hot water. Wood pellet boilers can be used in place of a standard gas or oil boiler to heat radiators or to heat the hot water.
These boilers can be easily fed wood pellets and can run automatically through a controlled thermostat. To keep the cost of the wood pellets down you can buy in bulk for greater discounts.
Installation of biomass boilers
The installation of a biomass boiler into a property is relatively easy. The boiler can be plumbed directly into the existing central heating. Biomass boilers do tend to be larger than ordinary gas or oil fired boilers, so adequate room will be required for both the boiler and the fuel store.
If there isn’t sufficient space inside, then Heat Cabins are available which house the boiler room and fuel store together. These are delivered as a self contained storage area and can be plumbed into the central heating pipes.
Maintenance of biomass boilers
Depending on the quality of the wood pellet, the residual ash could be around 0.5-1.5% by weight. The ash is neatly collected into the ash pan of the boiler, which can be removed and emptied manually at regular intervals depending on frequency of use. More advanced boilers can include automatic de-ash systems to automatically collect residue into an ash bin, meaning less hassle for the user. Please note that this ash can be used as a wood fertilizer.
Biomass boiler emissions
Biomass boilers are extremely popular due to their low C02 emissions. Burning biomass through these efficient systems releases the same amount of C02 into the atmosphere as is absorbed by the tree during its life cycle. Therefore, sourcing biomass from responsibly managed woodlands can make this an almost carbon neutral process.
