High Pressure vs. Low Pressure Boil

Nov 23, 2011· 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. However, these types of boilers are less common (especially in newer homes), and operate using a different system.
