A simple condensing boiler will however extract more of the sensible heat and some of the latent heat by cooling the flue gases down to below 1000C. When a condensing boiler is operating in its most efficient manner flue gas temperatures of around 500C will be achieved and the boiler will now start to condense the flue gases.

Condensing Gas Boilers | ANDRIANOS

Condensing Gas Boilers are high efficiency boilers that utilize the energy stored in exhaust gas.. In a conventional boiler, 10% of the combustion power is emitted to the environment through the chimney, with the exhaust gases at a temperature of about 150 ° C. Condensation technology uses the high temperature of the exhaust gases and, by cooling them, generates extra heat.
