What is the problem with the boiler? The fire is burning great but the water temperature isn't going past 70°. Problem just had started day before yesterday. Any advice is welcome
The boiler is turning off too early. Have you sat with it until it did turn off and then measure the temperature? The setting might have changed, but who changed it is another thing to puzzle out. OR You have a water leak somewhere taking water out fast enough that the temperature never gets over 70 degrees.
Sounds like a thermostat problem. Loose connection or gunk in the thermostat that is not giving an accurate temperature.
Thermostat. Leak pipe probably isn't the issue if the water pressure is holding.
