To meet the demand, the boiler is maintained in a hot stand-by mode. When the system demands heat, the pumps and control valves shift to send boiler water to the system. What comes back to the boiler is the “chilled” water (relatively cold) from the system. The result - THERMAL SHOCK.

The Temperature in Your Boiler and the Dangers of

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.
