    Managing Condensate for Condensing Boilers - Automatic Heating

    The condensing process is achieved by passing the piped hot flue gases through the cooler return water flowing back into the boiler. Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of 54°C or less.

    Is a high efficiency, condensing gas boiler the best

    Aug 13, 2018 · For example, a 30-year old boiler might be 70% efficient, meaning that for every dollar you spend on gas, 30 cents of heat escapes through the chimney or vent pipe. In comparison, a condensing boiler may provide up to 96% efficiency, which means that only 4 cents of heat escapes.
