Boiler Pressure - an overview | ScienceDirect Topics

Whereas hot water systems will normally operate at boiler pressures between 50 kPa and 300-400 kPa, high pressure hot water systems are used for industrial applications with pressures up to 2000-2500 kPa. The boiler construction is as for steam boilers, but the water line is held higher and the pipe system is sealed, with circulation by pumps.
