Boiler Operations amp; Boiler Maintenance | Oamp;M |

Steam boilers produce steam that flows through pipes from areas of high pressure to areas of low pressure, unaided by an external energy source such as a pump. Steam utilized for heating can be directly utilized by steam using equipment or can provide heat through a heat exchanger that supplies hot water to the equipment.

Is a high efficiency, condensing gas boiler the best

The biggest difference between condensing boilers and "conventional", non-condensing boilers is "efficiency". The most efficient boilers keep heat in the house rather than letting it escape through the chimney or vent pipe. An ultra-high efficiency boiler is able to keep more heat in the heating system, but the side effect is condensation.
