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.

Proper Boiler Feed Water Temperature Management …

Pre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency.
