Boiler Pressure Problem #1 Best HVAC Troubleshooting Tips

The setting on most pressure reducer valves is 12 PSI. That is likely the pressure on your boiler system. The pressure reducer can be adjusted to increase or decrease the pressure depending on the boiler system. Additionally if you have a bladder-type expansion tank then the for the tank should be checked for proper .

What is the safe pressure for a hot-water-heating system?

Jan 19 2015 · In my Cape Cod house with the boiler on the floor of my garage the pressure gauge reads between 12- and 15-psi (the dial is too small to read more accurately than that). The maximum pressure I am allowed it to get to is 30-psi because at that the relief valve will open. This is typical of residential hot-water .
