Read MoreDownloadable (with restrictions)! 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. However, monitoring the energy efficiency of …
Read MoreSep 09, 2021 · The functioning principles of a condensing boiler have been known for one hundred years, but its use has become possible only recently. This is because condensing boiler manufacturers can now make use of technological advances in the field of stainless steel and corrosion-resistant alloy design.
Read MoreThe condensing boilers' principle is based on the exploiting of the heat, which is still present on combustion emissions through technical solutions taking residual heat and transferring it to water.
