Principals of Condensing Boiler System Design

Conversely the focus for condensing boiler system design is to return 80˚F (27˚C) water to the boilers to promote 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 efficiency occurs at an EWT of 80˚F (27˚C) or lower. This EWT requirement varies with

Is a high efficiency, condensing gas boiler the best

Aug 13, 2018 · The biggest difference between condensing boilers and "conventional", non-condensing boilers is "efficiency". The most efficient boilers keep heat in the house rather than letting it escape through the chimney or vent pipe. An ultra-high efficiency boiler is able to keep more heat in the heating system, but the side effect is condensation.

Boiler-Venting Considerations - Heating Help

Aug 13, 2015 · A chimney liner would most likely have to be installed here. You will need to have the price for that in your estimate or design. Without the chimney liner, the flue gases could condense, ruining the chimney. Horizontal vs. Vertical Another rule to remember is that the horizontal vents must be no more than 75% of the vertical height of the flue. If using B Vent, the horizontal length can be the same length as the height of the chimney, as per International Fuel Gas …

Condensing boilers/ VSI or Mixing valves? — Heating Help

Nov 17, 2003 · However, on the boiler side there is a BIG difference. On a condensing boiler if the return water temps are not below the dewpoint (approx. 136 degrees F. for Nat. Gas) then there is no condensation on the fire side. This means that you have sold someone a higher priced condensing boiler that only sees about 85-87% efficiencies.

Great Expectations: Condensing Boilers | Kefid

Jan 12, 2018 · A condensing boiler achieves superior efficiencies when compared to a traditional boiler by capturing latent heat from the boiler flue gasses. The process requires a return water temperature below the dew point of the flue gas (typically around 130°F) and a heat exchanger surface capable of withstanding the corrosive qualities of the flue gas
