Condensing boilers require entering water temperature (EWT) in the 100˚F (55˚C) range to actually condense water out of the exiting flue gas. The onset of condensing is with an EWT of about 130˚F
How Can I Tell If My Circulator Pump Needs Replacement?
Managing Condensate for Condensing Boilers - Automatic Heating
You should set the temperature between 60 and 65 °C but for maximum efficiency, it should be set to around 60 °C. Do not set it lower than this as you could increase the risk of contracting Legionnaires disease. Legionnaires is a form of pneumonia thats caused by bacteria in water.
Mar 13, 2008 · Flue gasses condense at temps much warmer than 140. You should see flue temps of around 400* to 500* for nat gas. I realize that, at the boiler outlet, but 25' up, thru 4-6 45* el's, where it travels thru a ventilated attic, the flue gas temp drops way off. See attached attic flue pic. jogas.

The Definitive Guide to Condensing Water Heaters or Boilers
Oct 07, 2016 · To be able to condense the water vapour from the flue gas, the condensing boiler should operate using a lower entering water temperature than a conventional boiler. This is because the condensing process occurs at around 54°C.
Flue Gas Temperature and Heat in the Flue Gas Flow (Btu
The flue gas temperature can be determine in this case by an iterative process of inputting the flue gas mass flows and an assumed flue gas temperature to see if the Total Flue Gas Btu/hr is equal to 21,194.31 Btu/hour, if not you try another assumed temperature.
