Emissions and thermal efficiency for premixed burners

When the excess air rate less than 1.25, the thermal efficiency of the MF burner is lower than that of the SS burner. The excess air rate exceeds 1.35, thermal efficiency of the MF burner is higher than that of the SS burner. When adopting metal fiber burner at minimum heat load, the condensing gas boiler has the maximum efficiency.

Boiler Efficiency: Which Boilers Are Most Energy

All modern boilers that you can buy are condensing boilers, which are much more efficient than traditional non-condensing boilers. According to the energy saving trust, you could save as much as £340 a year on your gas bill if you're trading in an old-style non-condensing boiler for a new condensing one.

Boiler Efficiency — What Gross and Net Efficiency Mean

A 15% saving on a gas spend of £1,200 per year would save £180. If gas energy prices rise sharply, the saving with a new, high efficiency boiler would be higher too. Still, shorter showers, slightly smaller baths and slightly cooler houses could save more. A shower from a combi boiler (at 2018 UK gas prices) costs about £1.40 for each hour.
