| Overview |
| * |
|
Wood fuelled heating systems use natural wooden based materials such as wood, wood pellets and logs to power central heating and hot water boilers or to provide warmth in a single room. |
| * |
|
Carbon Neutral: despite releasing CO2 by burning wood, this is the same as was previously absorbed as the wood was growing |
|
| |
| Products: |
| * |
|
A standalone stove burning logs or pellets to heat a single room. Some can also be fitted with a back boiler to provide water heating as well. |
| * |
|
A boiler burning pellets, logs or chips connected to a central heating and hot water system. |
| * |
|
Log burning stoves and boilers have to be filled with wood by hand. Some pellet and chip burners use automatic fuel feeders which refill them at regular intervals from fuel storage units called hoppers. |
| * |
|
Air vents purposely made for wood fuelled appliances need to be fitted. |

| Planning |
|
| * |
|
You need to talk to your local authority if your flue will extend 1m or more above the height of your roof, or your home is in a Conservation Area or World Heritage Site and you plan to install a flue on the principal elevation visible from a road. |

| Cost and savings |
|
| * |
|
Costs for a standalone stove are around £3,000 including installation. A typical automatically fed boiler for an average home costs around £9,000 including installation and installing a suitable flue. Manually fed log systems are slightly cheaper. |
| * |
|
Savings in CO2 emissions are significant - up to 9.6 tonnes per year when a wood boiler replaces a solid (coal) fired system. |
| * |
|
Fuel savings can account for between £170 and £410 per year. |
| * |
|
Typically, heating and hot water costs for a year will be around £1,000 in a detached property. |
