The latest limits from Ecodesign in September 2018 reduced the emission level on all natural gas boilers up to and including 400kW to a level of 56mg/kW. This changed from net figures to gross. The previous best classification was Class 5 and stated at 70mg/kWh net. 56mg/kWh gross converted is 62mg/kWh net, so a reduction has been made.
