Re: Steam Pressure


Lower the pressure the better it works. 2-5 lbs is the norm.

Re: Steam Pressure


Check the air vents on the radiators if one is missing that could screw with you. They regulate the rate of heat through the system. If you change them becareful the vents may look alike but are rated differently by rad size, floor level and loop length. If you have too much pressure like 15 lbs the safety relief valve should discharge on the floor.

Re: Steam Pressure


No residential system is suppose to need more then 2PSIG.
If it does. Then something else is wrong with the system. Or the system was never designed or installed right.

Re: Steam Pressure


the p-trol (pressure control) is set to cut out at about 3 psi. the average normal boiler operates on average with less than 1 psi. normal steam pressure will vary from boiler to boiler but unless you like burnin fuel or need the pressure to travel further, then you'll see 1/4 to bout 1/2 psi on the guage

Re: Steam Pressure


Systems running at ˝PSIG and less. Are vapor systems.

As long as the vents are good and the pipes are insulated steam should travel just fine at 1psi.
