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

Jan 19, 2015· Most residential hot water heating systems run at 5-psi more than the pressure required to raise the water from the fill valve to the highest point in the system. 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
