Bio fuels are produced from organic material, either from plants or from industrial, commercial, domestic or agricultural products.

They are either woody biomass or non-wood biomass. Small-scale domestic appliances generally use wood pellets, wood chips or wood logs as fuel to power central heating and hot water boilers or to provide warmth to a single room.

There are two main ways of using wood to heat your home:

  • A standalone stove, burning logs or pellets to heat a single room. Some can also be fitted with a back boiler to provide water and heating as well.
  • A boiler, burning pellets, logs or chips connected to a central heating and hot water system.

Cost and maintenance
A typical wood fuelled stove costs around £4300, or £11,000 for a complete domestic boiler heating system. Maintenance is required and would include chimney sweeping to remove any build up of ash.

Financial help
This system is eligible for the Renewable Heat Incentive.

Planning permission
For more information about whether you will need planning permission, see renewable energy planning advice for householders.

If the system is installed in a smoke controlled area then permission will be needed to install an exempt appliance.
