Modern HydronicSystem Designs for Condensing Boilers

Typical modern boilers will fire natural gas as the primary fuel, with a percentage of these using #2 fuel oil as a backup fuel. A system designer should be aware of a couple of key points when in- volved with boiler fuel oil systems. 1) Most boilers firing fuel oil will have their own fuel oil pump.

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