Condensing boilers Heating Help: The Wall

The boiler has proved to be very reliable as have most condensing boilers available in Europe. The European version uses a Isothermic heat exchanger which is encased in a plastic housing (most boilers use this type of ht/ex now) As long as the system is flushed and cleansed well it will prove reliable. This is the UK web page.

Sizing a Modulating Condensing Boiler - GreenBuildingAdvisor

May 24 2016 · For the past few decades an increasingly popular space heating option is a system with a modulating condensing (mod-con) boiler. Because these boilers can potentially have a high efficiency (90-95% or higher) they are often promoted by state and utility subsidy programs. In a well-designed system the boilers efficiency can hit or even exceed its nameplate AFUE. But as installed most ...

Boiler Basics 101: Economizers for Increased Efficiency ...

Nov 27 2019 · While low temperature water or feedwater enters a boiler system high temperature flue gas exits. An economizer captures heat from the flue gas that would typically go to waste and utilizes it to preheat the feedwater. By doing this an economizer is able to increase thermal efficiency by decreasing the energy required to heat the water to ...

Why Our High Efficiency Condensing Boiler is inefficient?

The condensing the part of the water is from the gas fume. There's a lot of moisture in the flue gas. On a regular old-style boiler they just let the heat exhaust through the stack or chimney and the exhaust flue temperature can be as high as 150 ° C to 200 ° C or even more depending on the size of the boiler. In condensing boilers you're keeping the heat in the boiler longer.
