Understanding High Efficiency Boiler System Service

High Efficiency Boiler Basics. At the basic level, a boiler is just a pressure vessel. However, it is a pressure vessel that is designed to heat water and or produce steam which can be used to provide hot water or for space heating. As a source of hot water or a source of space heating, high efficiency boilers tend to last very long.
