  • Troubleshooting a Gas-Fired Hot Water Boiler - The

    In these hot water systems, once the radiator or baseboard convector is heated with the hot water, the cooled water is returned back to the boiler to be reheated, and the water circulation loop continues. Understanding the components of a hot water boiler helps you with basic troubleshooting steps.
