Indirect tank heating

Homeowner sent this to me and I think is overkill. Wanted to see what you guys thought.
Is a 80 gallon only used with left boiler with zone valve.

    Homeowner sent you that? What is yor relation to that quandary?

    If your in the trade good luck with that handy homeowner. You will never be right and resposible for everthing.

    Final thought.. Run.

    If unit 1 fails he want to be able to open valves so unit 2 can heat for him until unit 1 is running again.

    You could probably accomplish that with some manual valves for less cost and complication if you put the zone valve in the right place.
