Boiler Types and Classifications. There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler." Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler.
Properly maintained equipment performs more efficiently and reduces costs by minimizing probability for equipment failure and plant downtime. Each installation has its own specific design requirements but will only be as safe and effective as the maintenance program established.
