I'm buying a tankless electric water heater from Rheem. I want an 18 KW model, and I'm seeing two different ones when I go to buy online—RTEX18 and RETEX18. Is there a difference? I wonder if RETEX18 is a slightly older model, since it's cheaper on eBay but not showing up on retail sights.
Or maybe there's no difference at all?
Thanks for your help!
