What is the safe pressure for a hot-water-heating system?
Systems Help Center. At 28', it is 212 F. If the level of the water isn't high enough because there isn't enough fill pressure, the suction pressure on the loop may cause the first water to boil that comes from the boiler on a warm-start boiler. If you set the system pressure higher than needed, you decrease the amount of room for system expansion.
