What are the proper temperature settings for my boiler

The average setting for the aquastat (the temperature control device on a boiler) for a forced hot water system is 180 degreesF. It can be raised as high as 210 degreesF if needed in severe weather. For systems that use coils to heat domestic hot water, the high limit setting is 210 degreesF and the low limit setting 140 degreesF.

Specifying high-temperature hot-water boilers and systems

High-temperature hot-water (HTHW) plants are typically designed to operate at temperatures ranging from 350°F to 420°F. The system pressure must be at least 25 psig above the saturation pressure of the high-temperature water's maximum temperature to prevent pump cavitation and flashing of superheated water to steam.
