What is the correct temp setting for a hot water boiler

Your boiler is a block of iron that wants to remain warmer than the spent flue gasses (140F for gas, maybe 130F for oil). Let's call it 140 to be safe. If you set your boiler operating temperature below that for extended periods the flue gasses will condense, form acidic deposits and eat the boiler.

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 boiler's 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.
