Normal pressure and temp? — Heating Help: The Wall
The feed is at 12 psi, but when the boiler finishes firing, the gauge on the front says the pressure is up to about 25psi, and the temp is at about 250°F. Does this seem normal? I have two smaller boilers (S90s) and they don't seem to get as high, but maybe I just haven't looked at the right time. Thanks!
