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'.
How To Identify A Faulty Boiler Relief Valve
pressure of not less than the safety valve setting of the boiler but never less than 100 PSI. (B31.1 Para. 122.1.2). 2. Each Boiler must be fitted with a steam stop valve located at an accessible point in the steam-delivery line and as near the boiler nozzle outlet as is convenient and practical. (B31.1 Para. 122.1.7). A check

What is the safe pressure for a hot-water-heating system?
The ideal boiler pressure should be between 1 to 1.5 bars on your pressure gauge when your heating is switched off. Around 2 bars is a normal pressure level when your boiler is active/heating up. Anything below 0.5 is too low and must be replaced.

Where the maximum allowable working pressure of the boiler exceeds 100 psig (689 kPa), two bottom blowoff valves shall be provided consisting of either two slow-opening valves in series or one quick-opening valve and one slow-opening valve in series, with the quick-opening valve installed closest to the boiler.
How to check your boiler pressure levels: Locate the pressure gauge which is typically located on the side of the boiler. Read the pressure level. These levels should be around 12 to 15 psi. If the levels are significantly higher, this is most likely whats forcing your pressure relief
