How Does a Gas Boiler Heat Exchanger Work? Gas …

When there is a condensing boiler, the model has a comparatively more efficient heat exchanger that extracts the maximum quantity of heat from the burned gas. Condensing models can use either a power burner or an aspirating burner that has an induced draft fan. In addition they have a heat exchanger that is made of corrosion-resistant materials.

2019-9-3 · Think I'll opt for a stainless hx then. The boiler being replaced is at least ten years old and I'd hope the next one lasts longer rather than shorter. Now that latent heat's being extracted from the flue gas and most boilers are modulating I'd say there's not much further to go efficiency-wise so longevity is something to aim for. Thanks Jim

Secondary Condensing Heat Exchanger. In condensing furnaces, there is a secondary heat exchanger made up of small tubes that receive the exhaust gases once they have gone through the primary heat exchanger. Here, more heat is extracted, resulting in the gases that are cooled to the point that they condense into water and carbon dioxide.
