  Specifying high-temperature hot-water boilers and systems

  The system pressure must be at least 25 psig above the saturation pressure of the high-temperature water’s maximum temperature to prevent pump cavitation and flashing of superheated water to steam. Section 1004 of the International Mechanical Code (IMC) describes the minimum allowable requirements for boilers.

  Boiler losing pressure? Here's the likely causes (and how

  Boiler pressure is simply the balance of water and air within your boilers sealed system. In order to function correctly, your boiler needs a particular balance of water and air to ensure the pressure in the system is adequate for when water is demanded from the boiler – essentially when you switch on your heating or hot water.
