  • What is the safe pressure for a hot-water-heating

    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 pressure, the pressure relief valve will open. This is typical of residential hot-water boilers.
