FAQ the Water Boiler Is Overheating and/or Has High Pressure
Nov 20, 2007 · Boiler water temperature is controlled by the aquastat. It's not unusual for the boiler water temperature to increase 30 degrees after the stoker has shut down. This is because there is a pot full of glowing coal and is also the reason why there is a 40 degree spread between the low and high limit settings of the aquastat.

What Pressure Should My Boiler Be? Making Sure Your Boiler
They will cut out when the pressure falls too low and some models do the same when the pressure is too high. So if the pressure is too low, your boiler will turn off and you won’t have any hot water. Alternatively, high boiler pressure puts unnecessary strain and the system could break down. What pressure should my boiler be? Generally, your boiler pressure should be between 1 and 2 bar.
