Hi all. I'm new to this forum and glad I found you guys. I have drawn up some plans for a drainback solar hot water system and hoping for some feedback. Looking for any "gottchas" before I build it. My town plumbing inspector has already given his approval, but he's just concerned with code, not with it actually working correctly. I live in NJ, so freeze protection is mandatory. 2 adults and 2 kids live in my house. We burn corn for heat and use propane for everything else and as backup.

Assuming I'm able to succesfully drainback the 3/4" pipes within the unconditioned space, is there anything else I need to watch out for?

Details:
- Rheem 80 Gal. Solaraide tank with internal heat exchanger. Located in basement.
- Solar loop (closed) will contain RO water. No glycol. Pumped using a Taco 008 bronze pump wired to a differential controller. Head is only 10 FT because the drainback tank will be located on the 2nd floor just below the attic.
- Backup heater is a Takagi propane fired instant water heater.
- Solar collector will be an Apricus AP-30 mounted flush on the roof at 40 degrees facing SE with an approx 5 degree rotation toward South for header drainback purposes.
