  • Hydronic antitrust operating system
    Patent number: 4445638
    Abstract: A hydronic type of heating system is operated by a burner control system that relies on measuring the boiler water temperature and comparing the temperature change with a rate of rise set into a burner control means to determine whether the boiler is being properly operated. This system allows for heating the boiler water to a sufficient temperature before circulating the water through the heat exchange means to thereby prevent condensation on the outside of the boiler heat exchanger to eliminate rusting.
