        Understanding Boiler Pressure | Boiler Specialists

        In the early 1900s as boiler codes and rules were being established, it was decided that a high pressure boiler would be 15 PSI and above, with anything lower being defined as a low pressure boiler. The industry has maintained this standard for over a hundred years and boiler regulations and standards have been built around it.

        What happens if boiler pressure is too high? High boiler pressure isn’t dangerous, even if it’s showing as three bar on the pressure gauge. In most cases, the boiler will turn itself off if the pressure goes about a certain level and a working PRV should successfully control the pressure, preventing it from getting too high.
