Difficult to back track on the iterations on this thread but, the A7 is not to be an add-on to the old oil fired HWH, but you are apparently anxious to install it. The new GE hybrid is already an ASHP so doesn’t need the A7 attached. The old WH is being replaced with the new GE? Where are we with the A7? We old Farts think slowly.
