    Flue gas condensation can occur in any hot water boiler. The causes of this condensation and the importance of properly mitigating it are easily misunderstood. Flue gas condensation is also part of the reason why condensing boilers can have efficiencies up to 99% whereas a typical non-condensing boiler will max out around 80–85% efficiency.

    Flue gas condensation is a process, where flue gas is cooled below its water dew point and the heat released by the resulting condensation of water is recovered as low temperature heat. Cooling of the flue gas can be performed either directly with a heat exchanger or indirectly via a condensing scrubber . The condensation of water releases more

  • Condensing boiler - Wikipedia

    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., which would otherwise have been wasted.
