To prevent high temperature hot water from flashing to steam, a certain amount of overpressure is required. Look up the maximum operating temperature you want in the steam tables and find the corresponding pressure (i.e., 331˚F = 90 psi steam). Add 20 psi

When steam condenses, its volume is dramatically reduced, which results in a localised reduction in pressure. This pressure drop through the system creates the flow of steam through the pipes. The steam generated in the boiler must be conveyed through the pipework to the point where its heat energy is required.
