Understanding Biomass Boilers
Biomass systems (otherwise known as wood-fuelled heating), burn wood matter to provide a heat source either for a single room, or an entire heating system
What is Biomass?
Controlled in a very similar way to an oil or gas boiler, biomass wood pellet boilers can offer super efficiencies in excess of 90% meaning a more viable option for properties particularly in rural areas that currently have an oil or non-gas heating system installed.
Advantages of a Biomass Boiler system?
- Biomass boilers are said to be close to carbon-neutral
How much could I save with a biomass boiler?
Savings in carbon dioxide emissions are very significant - up to 14.5 tonnes a year when a wood-fuelled boiler replaces a solid (coal) fired system or electric storage heating. Financial savings are more variable - if you replace a older gas heating system with a wood-burning system you might save up to £80 a year, but if you are replacing an old electric heating system you could save as much as £650 per year assuming you are installing pellet central heating in a typical four-bedroom detached house with basic insulation.
Wood fuelled boilers, stoves and room heaters should be kept clean and swept regularly to remove ash. Ash quantities are generally very low (<1% of fuel volume). This is likely to be weekly and never more than once a day. Some appliances particularly boilers have self-cleaning systems built in which will collect ash from the combustion grate and the heat exchanger tubes. If there is no automatic ash cleaning mechanism in place the boiler will need to be shut down periodically so that this can be done by hand.
