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.
