Something I hadn't thought about before: If the storage tank for
the DHW panel is located below the panel and pump, designing the
fluidyne pump's check valves to be slightly "leaky" when wet
might allow for automatic drainback when the pump isn't running.

I'm not yet sure how that might best be done, but it would allow
completely passive DHW systems in cold regions...
