Low-pressure boilers are limited to a maximum working pressure of 15 psig (pound-force per square inch gauge) for steam and 160 psig for hot water (2). Most boilers used in HVAC applications are low-pressure boilers.hese types of boilers can be used to produce low or high pressure steam or water, and may be good alternatives for customers who are restricted by emissions regulations. Sizes range from 30,000 to 11,000,000 BTU input with overall efficiency generally in the range of 92% to 96% (2).
