Normally when buying a new steam boiler, one of the first parameters that are evaluated is its efficiency. This is because it represents the effectiveness of transforming the energy of the burned gas into steam. However, the single boiler's efficiency is not everything. If

Condensing boiler - Wikipedia

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.
