2013/3/22 · Condensing water boilers are increasingly desired by many building owners. This is due to the very high efficiency of these devices. Typical thermal efficiencies range from 90% to 98%. Many building owners are asking their consultants to use these devices for new, replacement, and retrofit applications.

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.

2021/5/14 · Condensing boilers can surpass the energy performance over the lower heating value, if the operating conditions enable the water vapor in the exhaust gases to condensate. Consequently, optimizing the operating parameters of condensing boilers is necessary to decrease fuel consumption without hindering water heating needs.

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, which would otherwise have been wasted., which would otherwise have been wasted.
