27/4/2018 · The firing-rate control will drive the burner to low-fire position at 2 psig and will stay at low fire until the boiler pressure reaches 4 psig, where the operating control will shut off the burner or increase the boiler firing rate if the steam pressure drops 1 psig lower.

Steam Heating System Operating Temperature

However a residential steam boiler pressure is so modest (0.2 psi to 0.5 psi) that the temperature increase above 212 °F will be no more than about 220 °F. A commercial boiler system heating a high-rise building may be operating at much higher pressures, perhaps 20 to 40 psi in order to be able to force steam to 20 or 40 floors of building
