The Normal PSI Reading for a Hot Water Boiler System | Hunker

Standard Cold Operating Pressure. The standard cold water operating pressure of most U.S. and Canadian hot water boilers is 12 pounds per square inch (psi). If the boiler pressure drops below 12 psi, the valve will allow new water into the unit to bring up the pressure reading.

6 Facts about Boiler Feed Water Pumps - Empowering Pumps

Jun 05, 2019 · 4. Boiler feed water pumping applications typically require high pressures due to the high temperatures of the feed water. Water changes to a gas state at 212-degrees F in atmospheric pressure. However, boiler feed water ranges are from 225- to 250-degrees F, and some can even reach temperatures as high as 350-degrees F.
