The GFX unit seems about as simple as you can get. Water falling down the
walls of a vertical pipe creates a large surface area for heat exchange.
Plus it's already approved by several plumbing codes.

There are several ways to plumb this, and I don't understand them all.
The web page (www.oikos.com/gfx/) shows a couple of options. It is
possible to link the preheated water right back into a shower, which is
perfectly in sync. Or you can feed the preheated water back into the tank.
