Older stoves are being replaced with the new, highly efficient, Ecodesign range.
Ecodesign is the European-wide programme to lower emissions from stoves. It comes into force in the UK in 2022. SIA Ecodesign Ready stoves have been sold for a number of years now and meet the Ecodesign requirements. The PM emissions limit for Ecodesign is 55% lower than for DEFRA exempt stoves.
A DEFRA exempt stove is a stove that has been tested against the government’s criteria for emission levels. DEFRA approved stoves are limited on the amount of smoke that they will produce during all stages of normal operation. Quite simply, these stoves limit the level the stove can be starved of air during the burning process. The lack of air in a stove creates more smoke.
The limits for Defra and Ecodesign are different and based on different measurement methods but for a Typical 5 kW stove at 80% efficiency the Limit for Defra would be 6.67 g/h. Defra exemption requires stoves to demonstrate they have low smoke emission at both a Rated or Nominal output level and at a minimum output or minimum air-setting.
Schiedel always recommend Ecodesign stoves. This mark is awarded to wood burning appliances that are verified by HETAS and meet the five fundamental requirements of the Regulation for efficiency and emissions.
- Seasonal efficiency,
- Nitrogen Oxide
- Carbon Dioxide emissions
- Particle Matter
- Organic Gaseous Compounds.
The SIA user survey also found that more than 27% of appliances are open fires or stoves that are over 10 years old.
As a result of significantly reduced efficiency when compared to modern wood burning stoves, open fires and older stoves account for over 51% of the UK’s annual wood fuel consumption and the marketing and sales trend is to encourage to upgrade their stove systems in the same way as an old car would need to be updated.
Clean Air Strategy
Schiedel Chimney Systems provide energy efficient flue systems and liners and always promote, within installation instructions and advice guides, that sweeping and maintaining stove systems is critical for reducing emissions as well as prolonging the life of the chimney system and the appliance
Usage for heating
Stoves are always a focal point for any house and home and are instantly desirable. However, these are not for aesthetic purposes only. People who don’t have a wood burner, automatically assume the purpose if for aesthetics, however, in some cases firing up a stove tends to heat larger rooms far quicker than conventional radiators would.
Particle emissions reduced by up to 90%
Burning wood produces particulate matter (PM) but the amount produced depends on how the wood is burnt. Independent research conducted by Kiwa Gastec on behalf of the SIA has shown that SIA Ecodesign Ready stoves can reduce particulate emissions by 90% compared to an open fire and 80% compared to an old stove
