Just wanted some opinions on the best way to add a HWH to the system.
The

I don't
think the volume is enough. The question is do I add it in series
(as a
"pre-warmer") or do I add it closer to the other side of the house
(parallel to
the system)? I'm not really interested in a tankless water heater.

You can install them at the point of use, or use them for the whole
