Technical Data

The purpose of this HETAS Stove Approval Scheme is to help consumers, retailers, installers and others to identify stoves with lower particulate (PM) emissions. There are concerns that small particle emissions known as PM2.5 to PM10 can be harmful. For that reason, we are operating a scheme which only accepts appliances that are tested to emit lower emissions compared to the current legal requirements. We have chosen to set the bar for entry at 50% less emissions than required for exemption for use in smoke control areas in the UK. We also note that Ecodesign legislation has differing, but important limits for other emission and any appliances listed here must meet those requirements as well as exceeding the particulate emission values for exemption by at least 50%.

Additionally, the product certified has been assessed for its compliance against the legal requirements for emissions and efficiency stipulated within the Ecodesign regulations. The performance of the appliance has been verified as meeting the following environmental attributes;

PM - Wood Logs 24.9 mg/m3
OGC Emissions - Wood Logs 3.55 mg/m3
CO Emissions - Wood Logs 170.35 mg/m3
NOx Emissions - Wood Logs 144.45 mg/m3
Seasonal Efficiency - Wood Logs 80.92126741%
Energy Label Ratings A+
