    Well theT&P will release at 210* and with tank stacking you may get a release. The hotter the storage the more the loss at standby.....Less effcient way

    The second option looks like a aqua booster. Drawing from both coil and tank at the same time is one method. Running it through the coil -tank on a draw is another......... Difference is pressure or self service.
