Pressure and Temperature gauge on hot water or hydronic heating boilers: this gauge displays the heating boiler internal pressure and temperature. Typical pressure for a residential boiler serving a two story home would show 12 psi cold, and less than 30 psi hot. Over 30 psi boiler pressure will cause the pressure relief valve to open.
High pressure steam boilers operate above 15 psi of steam pressure, and may be considerably higher. Inside a high pressure steam boiler water pressure may be 160 psig or higher. In the article above on this page see the section titled What are the normal hot and cold operating pressures of residential steam heating boilers?
The highest pressure the boiler should ever see is stamped on the boiler tag - Usually 30- or 50-psi. The pressure the system is designed to operate at is usually 12- to 25-psi for a two-story house, and 18- to 25-psi for a three-story house.
Because of its similarities in many ways to a steam boiler, the term ''hot water boiler'' is used. Hotwater boilers that have temperatures above 250° Fahrenheit or pressures higher than 160 psig are called ''high temperature hot water boilers''. Hotwater boilers that have temperatures not exceeding 250° Fahrenheit or pressures not exceeding 160 psig are called ''low temperature hot water boiler''s.
