Reducing emissions and improving boiler efficiency …

14/2/2019 · The equivalent steam boiler with O 2 control and a variable speed drive would have an efficiency of 88.5%, with gas consumption of 7,635 m 3 /day or 2,394,000 m 3 /year. Substantial savings would also be made by the variable speed drive on the electricity consumption of the fan motor, reducing it from 89,100 kWh/year to 41,700 kWh/year.

How efficient is my boiler? | Viessmann

Before the ErP directive, boilers were scored on the Seasonal Efficiency of a Domestic Boiler in the UK (SEDBUK) system, which assigns them a grade from A to G and an exact percentage score. For example, an A-rated boiler will get an efficiency score of over 90 per cent, while a G-rated model will get a score of under 70 per cent.
