A commercial boiler system heating a high-rise building may be operating at much higher pressures, perhaps 20 to 40 psi in order to be able to force steam to 20 or 40 floors of building height. For each psi increase in pressure in the system, the boiling point of water (assuming no coolant or antifreeze mixture has been added) will be increased by about 3 °F.
