Next we must understand state or phase change. Every time H20 changes phase from solid to liquid or gas, it either absorbs (Endothermic) or releases (Exothermic) what's known as 'latent heat'. The values vary depending on source and other conditions such as pressure but generally at atmospheric pressure the following applies Melting: absorbs 330,000 J/kg of latent heat Evaporation

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.This condensed vapour leaves the system in liquid form, via a drain.
