Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant of poor water quality, but require more physical space, than water-tube boilers. Regardless of boiler type, water quality is a critical aspect of implementing and operating an efficient steam plant.

should be noted that hot water return temperature is the driving factor that dictates boiler efficiency as shown in Figure 2, so optimizing the hot water return temperature with this consideration should be the goal. A standard hot water supply temperature for a con-densing boiler should start at a minimum of 140°F
Water is heated by a boiler and circulated throughout a building--usually homes (older homes, especially)--through a series of pipes that heat radiators that give off heat. The heat transfers to the air in the room. There are three basic types of hot water heating systems: gravity flow, pumped and baseboard convection systems.
