How to Set Hot Water or Steam Heating System …

What Are the Normal Hot and Cold Operating Pressures of Residential Hydronic (hot water) Heating Boilers? On a residential heating boiler the automatic water-feeder/pressure reducing valve that automatically provides makeup water to the heating boiler if pressure drops below 12 psi. So 12 psi is the typical "cold" pressure for residential boilers.
