Condensing boiler - Wikipedia

Condensing boiler. Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation,

CHAPTER 8 CHIMNEYS AND VENTS | 2018 International

The chimney or vent shall be resized as necessary to control flue gas condensation in the interior of the chimney or vent and to provide the appliance or appliances served with the required draft. For the venting of oil-fired appliances to masonry chimneys, the resizing shall be in accordance with NFPA 31 .

Choosing type of chimney liner based on combined burner

The concern with venting today is lower flue gas temperatures dues to less heat going up the chimney. That creates a possibility of condensing in the flue or chimney. I do not know of any gas conversion burners that give 90% efficiency. The typical combustion efficiency with most gas conversion burners is about 80% to maybe 82%.

Aug 13, 2015 · The boiler flue gases could condense until the stack gets warm, causing rollout. Once the stack was warm, the draft could be very high. A good rule of thumb is that a draft control should be used if the chimney is over 30 feet high. The draft control may range from a barometric damper to a

Is a high efficiency, condensing gas boiler the best

Aug 13, 2018 · What makes a condensing gas boiler so efficient? Condensing boilers produce heat by burning natural gas or propane fuel. The word “condensing” refers to the fact that these appliances are able to extract heat from the combustion process so efficiently that the flue gases leaving the boiler are at a much lower temperature than in a conventional boiler.
