correct pressure hot water boiler. Glenn Sossin_2 Posts: 592 Member. April 2007 in THE MAIN WALL. Residential systems usually have the feed valve set at 12psi. This would be the pressure when the system sits idle and has cooled down. As soon as you start applying heat energy, the water will expand. Thats why you have an expansion tank.

2019-10-18 · Introduction . CWNS series atmospheric hot water boiler is a type of horizontal internal combustion boiler. Its inner body communicates with the atmosphere, which ensures boiler operation under atmospheric pressure, and there is no need to worry about the dangers of pressure bearing due to its high safety coefficient.
Hot water boiler systems are equipped with a pressure gauge and an automatic pressure reducing valve that will add water to the system if the pressure drops. Despite the pressure reducing valve, owners should be familiar with the standard PSI of their hot water boiler system and should check the pressure reading regularly.
