Hot Water Heating Boilers 101: A Primer to Components, …

A condensing boiler; also known as a condensing hot water heater although referred to as a boiler in this article, is a type of boiler that is much more efficient than the traditional type appliance. Extra efficiency is achieved by extracting more energy out of the flue gas as compared to that of a conventional boiler and using this energy to pre-heat the return water flowing into the boiler.

Hot Water Heating Boilers 101: A Primer to Components, …

If that doesn't sound like much, consider that boilers that make hot water typically run up to 180ºF for each hot water thermostat call, virtually eliminating any efficiency gain. And if you look at condensing boilers that can run at lower temperatures, the Department of Energy estimates efficiency gains of a paltry 3% (again, for heat only boilers and less for boilers that make both heat
