If the low water cutoff probe gets dirty would this cause a problem with the water feeder when it is very cold out making the boiler run a lot ??/

    Or maybe the boiler has a lot of leaks, so when it runs a lot, it uses a lot more water. “Properly” and Oversized boilers cycle off the pressure switch with long runs. Higher pressure increases leaks.
