Oct 02, 2020 · Normal boiler pressure should be between about 1-2 bars [3]. The ideal boiler pressure is often marked as a range in green on the gauge itself. With red indicating the low and high boiler pressure zones. Bear in mind that your boiler may continue to work if the pressure is in these red zones.
Get a QuoteThe 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!
