Save up to £580 a year compared to electric heating.
Biomass is fuel developed from organic materials. It is a renewable and sustainable source of energy and is used for generating heat or electricity. Biomass as a fuel source is supplied typically in the form of biomass wood pellets for heating systems. There are many benefits to using biomass to heat your home:
- Biomass heating is the cheapest way to heat your home;
- Fuel savings of up to 50%;
- Excellent rate of return from RHI payments and a 3 – 4 year payback;
- Biomass increases the value of your property;
- Your carbon footprint can be reduced with savings of 16 tonnes of CO2 per annum;
- Biomass fuel can be sourced locally;
- Biomass fuel is less susceptible to price increases which affect traditional fossil fuels;
- A biomass boiler will last up to 40 years;
- Biomass is a sustainable fuel that is virtually carbon neutral.
Wood-fuelled heating systems, also called biomass boilers, burn wood pellets, chips or logs to to provide warmth in a single room or to power central heating and hot water boilers.
A stove burns logs or pellets to heat a single room – and may be fitted with a back boiler to provide water heating as well.
A boiler burns logs, pellets or chips, and is connected to a central heating and hot water system.
Biomass systems are wood-fuelled heating systems which burn wood pellets, logs and chips. The heat will warm a single room as well as power central heating and hot water boilers.
Biomass fuel is classed as ‘carbon neutral’ because it absorbs as much carbon when growing as it releases when burnt.
Check out the savings you could make with our chart below.
Biomass Cost Savings
|Fuel Replaced||Expected Saving||Expected Carbon Dioxide Saving|
|Electricity||£580 a year||7.5 tonnes a year|
|Oil||£280 a year||4 tonnes a year|
|LPG||£720 a year||3.5 tonnes a year|
|Coal||£300 a year||7.5 tonnes a year|
|Gas||£100 a year||3 tonnes a year|
Typically boilers are more than 90% efficient.
Carbon dioxide emissions are reduced significantly. A wood-fuelled boiler replacing a solid fired system like coal or an electrical storage heating system will save approximately 7.5 tonnes a year. Replacing a gas heating system with a wood-burning system could save around £100 a year. And changing your electric heating system for a wood-burning system could also save you as much as £580 per year.
Savings with Biomass Boilers (Wood-fuelled heating)
Savings in carbon dioxide emissions are very significant – around 7.5 tonnes a year when a biomass boiler replaces a solid (coal) fired system or electric storage heating.
Financial savings are more variable – if you replace a gas heating system with a biomass boiler, you might save £100 a year, but if you are replacing electric heating you could save as much as £580 per year.
*Please note that savings can vary depending upon situation.
Affordable heating fuel: although the price of wood fuel varies considerably, it is often cheaper than other heating options.
A low-carbon option: the carbon dioxide emitted when wood is burned is the same amount that was absorbed over the months and years that the plant was growing. The process is sustainable as long as new plants continue to grow in place of those used for fuel. There are some carbon emissions caused by the cultivation, manufacture and transportation of the fuel, but as long as the fuel is sourced locally, these are much lower than the emissions from fossil fuels.
Costs of Biomass Boilers (wood-fuelled heating)
A pellet stove will cost around £4,300 including installation. Installing a new log stove will usually cost less than half this, including a new flue or chimney lining.
For boilers, an automatically fed pellet boiler for an average home costs around £11,500 including installation, flue, fuel store and VAT at 5%. Manually fed log boiler systems can be slightly cheaper.
Pellet costs depend mainly on the size and method of delivery. Buying a few bags at a time makes them expensive. If you have room for a large fuel store that will accept several tonnes of pellets at a time, delivered in bulk by tanker, you can keep the cost down to around £190 per tonne in most parts of the UK.
Logs can be cheaper than pellets, but costs depend on the wood suppliers in your local area, as they cost a lot to transport.
Sources we used for Information on Biomass Boilers (Wood-fuelled heating)
GDS Property Services have used the following sources to obtain specific and accurate information. This allows us to provide up-to-date, valid facts and figures, on the costs, savings, and general information on Biomass Boilers (Wood-fuelled heating).
The carbon cycle starts when atmospheric carbon is absorbed by growing trees. With sunlight and water the process creates the complex carbohydrates required for tree growth via photosynthesis.
When organic materials such as trees die, the process of decomposing starts. During this, heat energy, water, and carbon dioxide are released back into the atmosphere. The carbon released during decomposition is then reabsorbed by the growth of new trees. This results in zero net atmospheric carbon gain.
The use of wood to produce biomass fuel works within this cycle. Dead trees can clutter forest floors for years due to the relatively slow rate of decomposition. Through harvesting these biomass resources, the heat energy they contain is captured and used. The natural process of decay is in fact accelerated when woody biomass is burnt. The heat energy given off can then be used to heat your property.
When the biomass wood pellets are burnt, the carbon released is returned to the atmosphere as part of the natural carbon cycle. New trees absorb this reintroduced carbon, and the cycle repeats again.
