This I believe would eliminate the need to keep the boiler lit during summer, but what is the effect of cold water running through the DHW coil of a shut down boiler? Perhaps I would have to build in a loop to bypass the boiler and not have water running through it?

Sure a dump zone could be added, but I prefer the indirect especially since you could have additional demands down the road. I really think folks underestimate the domestic hot water needs of a typical home. Today's tighter homes sure seem to be top heavy on the domestic demand, vs the heat load. Just one old man's opinion... I might add that I burn 24/7/365 so I like to avoid the summer condensation issues in equipment.
