    2019-10-15 · Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.

    2018-5-22 · Lower water temperature means higher efficiency. Condensing hydronic boilers can operate at efficiencies higher than 90%. The key is to have incoming feedwater at temperatures below 140°F, and to be able to either modulate the boiler or have sufficient redundancy that operating units can be held near their optimum efficiency.

    2018-9-10 · condensing and non-condensing boilers. Condensing boilers are more efficient because they transfer more heat out of the combustion gases and into the circulating water than non-condensing boilers. They do this by utilizing a secondary heat exchanger that harnesses and effectively handles the energy from the condensation process.

    However, many newly installed systems only achieve a fraction of their expected energy savings. The efficiency of condensing boilers is extremely sensitive to operating conditions — in particular the temperature of the water entering the boiler. Often, an effective retrofit requires modifications of the boiler system controls and/or piping.

  • 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. However, monitoring the energy efficiency
