The results are highlighted in Figure 4 below. Note that the dew point has been lowered from 130.6 degrees to 117 degrees and the boiler is no longer in the condensing range. This represents a 3.7 per cent decrease in overall efficiency and this is just the beginning of the bad news.

Since the final exhaust from a condensing boiler has a lower temperature than the exhaust from an atmospheric boiler 38 °C (100 °F) vs. 204 °C (400 °F) a mechanical fan is always required to expel it, with the additional benefit of allowing the use of low-temperature exhaust piping (typically PVC in domestic applications) without insulation

Jun 19, 2012· When the required system’s supply water temperature is 180 to 190 F, which is too high for condensing boilers to condense, the system will operate with the less expensive, noncondensing boilers. Based on OAT, the system’s supply water temperature shall be adjusted.

Condensation? Return water temperature vs Boiler

The boiler if cold start will always go through a period of condensation until it gets above 130. The faster it gets above 130 the better, and staying above 130 at shut down until it cools off is fine. Some photos of the boiler piping would help, and what kind of emitters are used.

This boiler starts to condense when the OAT is above about 56° F. Now, for example, between 55 and 65 OAT in Burlington, Vermont (a cold climate, ASHRAE 6 A / B), that’s still about 2290 hours or 33% of the hours the boiler will operate. Not bad, but it leaves 67% of the time when the boiler is not condensing.

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.
