  • What Pressure Should My Boiler Be? Making Sure

    2019-10-10 · The pressure is crucial to your heating operating properly. Most boilers have a way of detecting if the pressure is off. 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.
