You may have been made aware recently of the Governments intentions to better promote the use of clean-burning solid fuels, appliances and operation techniques through its Clean Air Strategy, in order to continue to reduce the impacts of solid fuel appliance use on the UK’s air quality.
In simple terms, the Ecodesign Regulations set new minimum seasonal efficiency and maximum emission requirements for solid fuel burning roomheater stoves, roomheater stoves with boilers and cooker appliances.

What is EcoDesign?
In simple terms, the Ecodesign Regulations set new minimum seasonal efficiency and maximum emission requirements for solid fuel burning roomheater stoves, roomheater stoves with boilers and cooker appliances. Only those appliances that have been tested and verified as meeting these new limits will be able to be sold and installed legally within the UK. The emission limits include those for Particulate Matter (PM), Organic Gaseous Compounds (OGC), Carbon Monoxide (CO) and Nitrogen Oxides (NOx).
What efficiency and emission requirements for solid fuel appliances are currently enforceable?
Currently solid fuel appliances made for sale on the UK market are required to meet minimum gross efficiency limits of 65%, when operated at the appliances nominal heat output, as prescribed within the current UK Building Regulation requirements. This is to ensure that any new or replacement solid fuel appliance installation does not significantly reduce the properties overall energy usage and performance. Where pellet roomheater appliances are concerned, this efficiency limit is increased to 70%, in most case due to the higher levels of controllability associated with pellet burning appliances.
The only emission performance limits for appliances are prescribed with the Construction Products Regulations, which currently stipulate a maximum emission limit for CO at 12,500mg/m3. Current manufacturing standards do not at present stipulate a maximum emission requirement for PM, OGC’s or NOx.
So, what exactly will change after 1st January 2022?
After 1st January 2022, all solid fuel burning roomheater appliances will be required to have been independently tested to show that they meet the seasonal efficiency and four emission limit provisions as laid down within the Ecodesign regulations. This will include a dramatic reduction in the CO minimum emission limit stipulated above.
