Boiler has too much pressure — Heating Help: The Wall

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. Typical hydronic heating boiler operating temperature settings are LO-120-160 HI-180-200 °F. At 200 °F. we'll see should see pressure under 30 psi.

The Normal PSI Reading for a Hot Water Boiler System | Hunker

Jan 19, 2015 · The water pressure in a hydronic boiler shouldn't be over 12- to 15-psi. It should have only enough pressure to raise the water a few feet above the top of the highest point in the piping system. A 12-psi setting will lift water 28' above the fill valve. A 15-psi setting will lift the water to 34'.
