High Pressure vs. Low Pressure Boiler

Nov 23, 2011· (The measurement psi is used to determine pressure, and stands for pounds per square inch.) By definition, a high pressure boiler is one that operates above 15 psi, while a low pressure boiler is one that operates at 15 psi or lower. Steam heating systems run with even lower pressure, typically at less than 1 psi in all.
