Principals of Condensing Boiler System Design

boiler heating water system as a whole. 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 (54˚C), but maximum

condensing boiler efficiency with high return temperatures

Low return temperatures provide a means to lower the stack temperature. Typically condensing boilers run a stack temp about 30-40 degrees warmer than the return temp. Exhausting higher temperatures is of course a waste of heat up the chimney and wasted dollars.

Maximizing Small-Boiler Efficiency | HPAC Engineering

It is worth noting that this reset curve is specific to boilers that can tolerate condensing flue gas caused by sustaining return-water temperature below 140 F. In general, do not apply this curve to a non-condensing boiler, as the flue and boiler will need to be replaced prematurely because of corrosion.

Which Condensing Boiler is Best? | U.S. Boiler Company

Our extensive selection of heating products includes two super-efficient condensing gas boilers, the Burnham Alpine™ and K2™ boilers. How do condensing boilers differ from conventional boilers? The answer is "efficiency". The most efficient boilers keep heat in the house rather than letting it escape through the chimney or vent pipe. A condensing boiler recovers some of the wasted heat and is on average, 25% more efficient than a conventional boiler.

Apr 11, 2012 · The vapor in the flue gas only starts to condense at about 130° F return water temperature. You get very little increase in efficiency beyond non-condensing operation at this temperature. Slightly above a 70° F return water temperature is when you hit the 98%-99% efficiency numbers you often see advertised.
