Biomass systems are also known as wood-fuelled heating systems and burn wood chips, pellets or logs to power central heating, boilers or warm a single room.
We can supply and install a range of biomass systems for clients in Devon, Somerset and Dorset at competitive prices.
The benefits of wood-fuelled heating
Costs, savings and earnings
A pellet stove will cost about £4,300 which includes installation. If a new log stove is installed, the will cost less than half of this amount including chimney lining or a new flue.
Automatically fed pellet boilers for a home cost about £11,500 with installation, VAT at 5%, fuel store and flue. A manually fed boiler system is slightly cheaper.
The cost of pellets depends on the method of delivery and the size. If only a few bags are bought each time it is needed then it will make them expensive. If there is a large fuel store for several tonnes of pellets and delivered by tanker then this will keep the cost down to about £190 per tonne in most areas of the UK.
Logs can often be cheaper than pellets but this depends on the local wood suppliers as they are expensive to transport. If you are able to store enough logs for more than a year then you can buy unseasoned logs to let them season for a year which will save you money.

When a wood-fuelled boiler replaces an electric heating system or a solid fuel system then at least 7.5 tonnes of carbon dioxide can be saved a year. The financial savings of installing a wood boiler vary much more. If a gas heating system is replaced with a wood heating system then you could save £100 a year, but if you replace electric heating then you could save at least £580 a year.
The table below shows how much can be saved by installing a biomass heating system in a standard semi-detached three-bedroom house with basic insulation:
|Fuel Replaces||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|
The savings above assume that the house has been properly insulated, as we always recommend that home owners make sure their home is insured correctly before they consider installing a renewable energy system. As well as saving money from insulating you could also save money by switching to wood heating.
For the heat you generate from the wood boiler, you may be able to get payments through the government's Renewable Heat Incentive (RHI). This scheme is planned to be launched in October this year.
You might be able to get assistance through the Renewable Heat Premium Payment scheme with the cost of installation for a wood boiler from August 2011.
Log and pellet stoves aren't expected to be supported by the RHI and are not eligible for Renewable Heat Premium Payments.
