Proper Boiler Feed Water Temperature Management | Powerhouse

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.

boiler heating temperature

Boiler Gauges how to read the temperature & pressure. Typical operating temperature settings on a boiler call for a Low temperature (boiler cut-in) between 120 and 160 °F. Typical operating temperatures on a hydronic boiler call for a high temperature (boiler cuts off) of 180-200 °F. Over 200 degrees F.

Steam Heating System Operating Temperature

Because a steam boiler makes heat by producing steam - by boiling water at sea level the temperature at the boiler will be boiling or 212 °F or close to that figure. The actual steam boiler temperature may be a bit lower at high elevations above sea level and the steam boiler temperature will be a bit higher than 212 °F for boilers operating at slightly higher pressures as we'll illustrate in a table below.

Residential Steam Boiler Basics - The Spruce

The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers they are inherently less efficient than their hot-water cousins and are more finicky to operate.
