Pressuretrol settings
How long should a steam system “hold” pressure after the boiler cuts out at the high pressure limit? I did some testing at 1.5 psi (with a 0.5 psi low limit). Boiler cuts out at 1.5 psi, but pressure falls so quickly that the boiler fires again within 60-90 seconds. Doesn’t seem like much of…
