Your guide to safer boiler operation

Classification of boilers – High-pressure boilers are boilers operating at a steam or other vapor pressure in excess of 15 psig, or a water or other liquid boiler in which the pressure exceeds 160 psig, or has a temperature greater than 250 degrees Fahrenheit. Others are low-pressure boilers. License requirement
