Gas Condensing Boiler Seasonal Efficiency

Gas Condensing Boiler Seasonal Efficiency Related Information

Monitoring energy efficiency of condensing boilers via

2018-1-1 · The operating principle of condensing boilers is based on exploiting heat from flue gases to pre-heat cold water at the inlet of the boiler: by condensing into liquid form, flue gases recover their latent heat of vaporization, leading to 10–12% increased efficiency with respect to traditional boilers.

2020-7-22 · Gas condensing boiler With condensing technology, not only is the heat from the combustion of fuel oil or gas utilised, but also the heat that, with non-condensing heating technology, would otherwise escape unused up the chimney. Condensing boilers extract almost all of the heat latent in flue gases and convert it into additional heating energy.

In a multiple-boiler system, the seasonal efficiency of any individual boiler is permitted to be 80 percent. However, the efficiency of the entire system must reach 84 percent overall. Nevertheless, there is a strong trend towards the use of condensing boilers in non-domestic and commercial buildings.

Typically a condensing gas boiler would have seasonal efficiency of 88% compared with a non-condensing boiler at 75% and some older type boilers at 55-60%. When in condensing mode (for condensing boilers do not condense all the time) the flue gases give up their 'latent heat' which is then recovered by the heat exchanger within the boiler.
