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 | Powerhou

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.

The average setting for a gas-powered hot water boiler is 180°F. This provides the appropriate level needed for most cold weather temperatures. If you can raise the temperature manually, do not set it any higher than 210°F (which is often the limit), and try to remain down at 190°F if you need the extra heat.

Improve Your Boiler’s Combustion Efficien

On well-designed natural gas-fired systems, an excess air level of 10% is attainable. An often-stated rule of thumb is that boiler efficiency can be increased by 1% for each 15% reduction in excess air or 40°F reduction in stack gas temperature. Suggested Actions Boilers often operate at excess air levels higher than the optimum.
