Boiler Types and Classifications - Wiki - odesie by
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.
