  • A Novel Modelling Approach for Condensing Boilers Based on

    Condensing boilers use waste heat from flue gases to pre-heat cold water entering the boiler. Flue gases are condensed into liquid form, thus recovering their latent heat of vaporization, which results in as much as 10%–12% increase in efficiency. Modeling these heat transfer phenomena is crucial to control this equipment. Despite the many approaches to the condensing boiler modeling, the Learn More

  • What is a condensing boiler? Why they don't condense

    Mar 05, 2020 · A condensing boiler is a form of gas boiler that can work at a higher efficiency. Non-condensing gas boilers could lose up to 40% of the heat they generated via the flue, whereas condensing boilers can recover most of that heat by capturing it before it leaves the flue and re-cycling it to pre-heat the boiler.Learn More

  • How To Optimize Your Condensing Boiler System For Maximum

    Feb 08, 2019 · For condensing boilers, you need a return water temperature of 80°F or lower in order to achieve 97% efficiency. (Look at the efficiency curves from any common condensing boiler manufacturer to see this.) Put another way, you start gaining efficiency only when your return water temperature is approximately 135°F or lower.Learn More

  • Multi-Fuel Condensing Hydronic Boilers

    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 or conventional chimney requirements. Indeed, the use of conventional …Learn More
