Regulations for Domestic Biomass Combustion
The most common reason that biomass is burned domestically is to heat spaces, for example using wood stoves, or to heat water in a biomass boiler. Emissions regulations tend to be different depending on whether it is space or water which is being heated, although there are overlaps, for example in the case of stoves with back boilers.
The Ecodesign directive applies to solid fuel local space heaters with output up to 50 kW and solid fuel boilers with output up to 1 mW. It sets limits for oxides of nitrogen, particulate matter, carbon monoxide and organic gaseous compounds. The Ecodesign directive for solid fuel boilers comes into force on 1st January 2020 and applies to solid fuel local space heaters with effect from 1st January 2022.
