  • Do condensing, 90%+ boilers always condense? — Heating

    A condensing boiler extracts additional heat from the waste gases by condensing this water vapor to liquid water, thus recovering its latent heat of vaporization. A typical increase of efficiency can be as much as 10-12%.Get Price

  • Condensing: or not condensing? | PlumbersForums.net

    Sep 27, 2009 · Condensing is dependent on the return temperature. This has to be below 55 deg C. It does not matter what the flow temp is. Some boilers are still designed to run with an 11C differential, so if the flow temperature is above 66C the boiler will rarely condense. Other boilers now use a 20C differential, so you can be sure of condensing, provided Get Price

  • - How to maximise domestic condensing boiler efficiency

    A condensing boiler has two main heat exchangers. This time the water enters the secondary (and condensing) chamber first. Picking up latent heat from the hot flue gases as they cool. The moisture in the gases condenses into droplets that form at the bottom of the heat exchanger.Get Price

  • Modern HydronicSystem Designs for Condensing Boilers

    Mar 05, 2020 · The process is called condensing because the heat needs to turn back into water before it leaves the flue via the second heat exchanger. When the temperature of the water - as it returns to the boiler - is less than 54 degrees C, the boiler will run in what is known as 'condensing mode'. This is when the boiler starts to recovers its lost heat.Get Price
