2020/9/18 · Condensing boilers To increase a boiler's efficiency above the 85% threshold, the flue gas needs to be allowed to condense on the heat transfer surface. Efficiency of these condensing boilers is greatly increased by both lowered allowable water temperature, which

Condensing boiler - Wikipedia

In a condensing boiler, heat existing in the flue gasses can be captured and 'recycled' back into the heating system and used to preheat the cold water entering the boiler. During this process, the temperature of the flue gas is rapidly reduced from around 130℃ to 50℃. This fall in temperature causes condensation, from which the name is
