  • HEATBASE FACTSHEET 17 Problems with Condensing Boiler

    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.Learn More

  • What is a Condensing Gas Boiler? | U.S. Boiler Company

    Traditional vs. Condensing Gas Boilers. Traditional gas boilers burn natural gas or propane to heat the water in a home heating system. These boilers are vented to the outside via a chimney flue or vent pipe. Traditional boilers typically operate at higher temperatures, which means that a portion of heat is vented to the outside during the Learn More

  • At what temperature does flue gas condensate?

    In this way, at what temperature does a boiler condensate? 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 efficiency occurs at an EWT of 80˚F (27˚C) or lower.Learn More

  • MAXIMUM ENERGY GAIN FROM FLUE GASES

    Our flue gas ercs condensation plants recover up to 50 % of the boiler output from thermal energy in heat contained in otherwise unused flue gas. The latent heat of the evaporation or condensation heat is recovered by condensing flue gas. In addition, one part of the sensible heat can be extracted by means of a decrease in tem-Learn More

  • Changing atmospheric boilers to condensing boilers

    The flue system must be water tight and pressure tight, and designed to drain the condensate from the flue and prevent flow back into the boiler. Where possible you may be able to make use of the existing chimney with a liner thus enabling it to cope with condensing operation.Learn More

    Flue gas condensation can occur in any hot water boiler. The causes of this condensation and the importance of properly mitigating it are easily misunderstood. Flue gas condensation is also part of the reason why condensing boilers can have efficiencies up to 99% whereas a typical non-condensing boiler will max out around 80–85% efficiency.Learn More

  • Boiler Flues - Ultimate Guide with Boiler Flue Regulations

    Nov 05, 2019 · Boiler flues are fitted when using combi, regular, and system boilers. The only exception that may apply to a small number of homeowners is a back boiler. This is a type of boiler that is fitted behind a fireplace. If you have a gas boiler behind your fire, the emissions will exit through your chimney, rather than via a boiler flue.Learn More

  • Condensing boilers | Jeremias® Exhaust Systems

    The condensate is acidic and decomposes base metals. Therefore, a high quality stainless steel must be used for venting that is highly resistant to this condensate. Since the exhaust gas from the condensing boilers is cooler, it has very little natural draft and requires some fan assisted pressure to …Learn More

  • Best Condensing Boilers - 2021 Guide to Costs & Benefits

    Feb 01, 2021 · A condensing boiler is a boiler that utilises the heat of its gas to warm the water within your homes heating system. With non-condensing boilers, that heat is lost as hot gases disappear into the flue. While condensing boilers are a type of boiler, it's important to understand that they can still be either a combi boiler, a system boiler or Learn More

  • flue gas condensation question — Heating Help: The Wall

    Feb 23, 2004 · Now we come to condensing boilers which uses an aluminum or stainless steel heat exchanger and the cooled return water meets the flue gases furthest away from the flame, and discharges from the hottest part of the heat exchanger, so we are now sucking every drop of heat out of the flue gases, in fact if the return water is 90F the combustion Learn More
