      Monitoring energy efficiency of condensing boilers via

      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.

      This was necessary to prevent the water vapour produced by combustion from condensing back to liquid water and flooding the combustion chamber. Part of the lost 17% (about 10% of the heat produced by combustion) was being used solely to keep the water from combustion as steam. So a boiler with a gross efficiency of 82% becomes a boiler with
