    No need to add....

    anything. No different that adding an indirect to a hot water boiler. No room for a tankless water heater?

    Sizing DHY loads:

    Kind of an exercise in futility?

    Size the DHW load by the way it is supposed to be added to a boiler, then picking boiler for a 30,000 BTU load at design temperature. When the DHW load calculates to over 100,000?

    Its a "Phantom Load". Just put in a bigger indirect.

    SNARK Off.
