  • Is PVC an acceptable vent material for flue gases?

    Some boiler and water heater manufacturers offer stack or flue gas temperature gauges as a way to see whether the unit is scaling up and losing efficiency, which is helpful for monitoring the flue condition. A temperature sensor or probe with a high-limit control could be inserted into the flue at the flue connection to the boiler or water

  • Is a high efficiency, condensing gas boiler the best

    Condensing boilers produce heat by burning natural gas or propane fuel. The word "condensing" refers to the fact that these appliances are able to extract heat from the combustion process so efficiently that the flue gases leaving the boiler are at a much lower temperature than in a conventional boiler. The temperature of these flue gases

  • Managing Condensate for Condensing Boilers - …

    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.

    2008-3-13 · As I am now dealing with a job that has Lochinvar CHHN0990 non-condensing boilers that were condensing in the boiler as well as the flue, I've done a little search and found that natural gas flue gas condenses at 60*C, which equals 140*F. Coincidentally, that is the minimum allowable return water temperature to these boilers. Return water less than 140* is no longer a problem.
