1/1/2018 · The operating principle of condensing boilers is based on exploiting heat from flue gases to pre-heat cold water at the inlet of the boiler: by condensing into liquid form, flue gases recover their latent heat of vaporization, leading to 10–12% increased efficiency with respect to traditional boilers.
If the condensing boiler can run constantly at varying firing rates, then it'll hit that steady-state nirvana almost 100% of the time. The other boiler will cycle on-off which means increased losses until the HX hits its steady state. Plus, the condensing boiler can operate constantly even when the water temps to supply the load are very, very low.

Boiler Heater: Types and Applications - Wattco A boiler heater is a closed tank or a vessel in which it uses a flanged heater so water and many other types of fluids are heated. The liquid content inside the contraption does not actually boil but is only allowed to be heated to keep it stable and preserved.
a wider ΔT will keep the boilers in a condensing mode more often, increasing system efficiency.
