  • How do I adjust the hot water temperature on my boiler?

    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. we're at risk of spilling at the pressure temperature relief valve.Learn More
