Condensing vs. Non-Condensing Boilers | JLC Online

30/4/2020 · A condensing boiler, on the other hand, has components in the flue system that transfer some of that thermal energy from the hot exhaust to the water that is being heated. In the process of transferring that energy, the exhaust gases cool enough to cause condensation of the water vapor from those gases, hence the name "condensing boiler."

Buying and operating tips—boilers, commercial

A condensing commercial boiler operates at peak efficiency when the water returning to the boiler is lower than the temperature of the condensing flue gas—in the range of 45–50ºC. Otherwise the flue gases will not cool enough to recover the latent heat. If an existing distribution system is designed for high temperature water, look into
