  • bad pressuretrol, bad pressure gauge, or something else

    re: 2 PSI cold That pressure gauge is shot if it reads 2psi when the boiler is not steaming and is probably not reliable. If you replace a 30 psi guage you need an internal syphon 0-30psi gauge. If you look at the picture on my original post you can see my 0-30psi gauge behind a romex cable.Get Price

  • boiler water pressure is 50psi -

    Oct 10, 2004 · 50 Psi in boiler pressure. 50 PSI is far far too high. Drop it down to about 10 psi. At 10 psi the water will rise to 23ft so unless you have a home that that has a rad higher than say 20ft. Excess pressure do not do the system any harm if all components can take that pressure but don't do the system any good either.Get Price

  • Why steam boilers short-cycle | Liming | Plumbing and

    Jul 20, 2015 · You see, the steam pressure inside the pipe and radiators blows closed the little floats inside the air vents, and unless that pressure drops, the vents won't open. And if no venting takes place after the first cycle, most of the air won't leave the system. And where there is air, steam will not go. When that happens, the burner short-cycles.Get Price

  • Boiler getting overpressurized -- reaches 30 PSI and PRV

    Jan 05, 2021 · There's also a pressure and thermometer gauge on the left side of the casing around the boiler. These two gauges give very different readings at the gauge on the pipe reads higher for temperature, and the gauge on the boiler reads higher for pressure. When the boiler heated up tonight, the gauge on the pipe got up to 31 PSI and 210 degrees.Get Price

  • Steam Boiler Pressuretrol wont cut in/out. — Heating Help

    It should be possible to set the L404F1060 to cut out at a bit less than 2 psi, although nominally the minimum cutout is 2. The differential can be set a bit lower than 2 also -- so it should work. Your PA404A should work as advertised -- that it does not seem to suggests very much that it needs to be calibrated; most of them seem to.Get Price

  • Pressuretrols keep boiler switching btwn 50% - Heating Help

    The boiler will get out of high fire quickly as soon as the piping is hot and main vents close, and the 75% fire raised to 80 to 85% so that pressure builds a little more quickly than the slow rate you have. Then the low fire adjusted upward so the 2.5 psi holds. This would be perfect, and everything would heat.Get Price
