The Temperature in Your Boiler and the Dangers of

Once a boiler starts to go over 212°F, you can face serious problems. Watch out for overheating. If you notice that your boilers temperature is going higher than the above settings, you have a major problem. If a boiler has reached 220°F, a sudden drop in pressure could cause the tank to burst. Overheating also is the main cause of leaking.
