The Normal PSI Reading for a Hot Water Boiler System | Hunker
Hot water boiler systems also have a high-limit temperature setting that triggers an automatic shutdown if the water temperature rises above that set point. If the high-limit temperature setting is too high, generally over 200 degrees Fahrenheit, the system pressure will reach an excess condition as well and start leaking.

How dangerous is it if your boiler pressure is well high
if you're boiler manual says it's maximum pressure is at or below 3 bar then fair enough (virtually all boiler manuals are available online), but every boiler installation should have a pressure relief valve that's set to relieve pressure before it becomes dangerous anyway, so it's very unlikely to be at a dangerous level.

Boilers High Furnace Pressure - Specific causes
High Furnace Pressure Problems in Boilers. The rate of change in the furnace pressure can vary very much, that is from a simple sudden surge due to fuel variations to a huge furnace explosion. Combustion in a boiler furnace is normally considered a controlled explosion, as all boilers operate at a regime where explosion pressure is the maximum.

My Boiler Pressure is Too High? A 24|7 Home Rescue Guide
Why is my boiler pressure high? We often say that a boiler’s pressure should be at around one bar, but this is only when your central heating is turned off and you are not running any hot water. When your boiler starts heating up water, the water expands (think of how steam takes up more space than water), which causes the pressure gauge to jump up.

Is My Boiler Pressure Too High? | Hometree
Boiler pressure refers to the pressure of hot water running in your sealed central heating system, while water pressure is the pressure of the water coming through your taps. Boiler pressure is important for several reasons. Primarily, if you have low boiler pressure your system could cut out, preventing your central heating from working. Alternatively, if there is high boiler pressure, the system will be strained beyond normal capacity and could potentially fail.
