How do wood fuelled heating systems work?
You can choose between different biomass fuelled heating systems depending on whether you'd like to heat a room or your whole house and which fuel you'd like to use.
Technical information made simple
There are two main ways of heating your home with wood:
- A standalone stove; Typically heating a single room, stoves can be fitted with a back plate to provide hot water too.
- A boiler; Like a traditional boiler they would be connected to the central heating system to heat the home and provide hot water.
Types of Wood Fuel
There are three main types of wood fuel that can be used in your home:
- Logs – These are cut directly from the tree, but need to ‘season’ for about a year ideally before burning. They are generally easy to get hold of, but are bulky and heavy.
- Chips – This is clean, untreated waste from saw mills and forests. They are typically used in larger systems so not often seen in domestic homes.
- Pellets – These are manufactured from timber waste that would have normally gone to a land fill site. They are treated and compressed making them denser and dryer so that they are less bulky and burn with uniformly high efficiency.
Stoves and boilers that burn logs have to be filled with wood by hand, but there are some pellet and chip burners that use fuel feeders, which automatically add the fuel at regular intervals.
In order to qualify for the How does the RHPP work? the system must be fitted by a MCS accredited installer. Find out more about the Renewable Heat Incentive and RHPP for wood fuelled heating systems.
It is also important to use an installer that is HETAS accredited, but if not then you should notify your council’s building control department who can arrange to check the installation.
- Can you burn straw as biomass for heating?
- Yes, you can burn straw pellets in some models.
- Can you burn logs in a biomass boiler?
- Yes, many designs allow the burning of logs and in some models the burning of both logs and pellets.
- How much do wood pellets cost?
- Complete our Home Energy Assessment to get an accurate estimate of the capital and running cost of a biomass boiler for your house.
- Can biomass be burnt in a smoke controlled area?
- Biomass can be burnt in a smokeless zone, but it would need to be approved by the DTI and the environmental agency.
