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.

Selecting a Boiler Stack Key Considerations for Selection

Factors such as boiler temperature, chemicals released during combustion, condensation, corrosion, and wind influence material choices. For example, the condensate expelled from a condensing boiler is acidic. As a result, rust could become an issue. Selecting a stack system made up of the right materials, thus, is critical to ensuring optimal

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.
