Small electric tankless instead of hot water recirculating?

I've been looking into hot water recirc options for a distant kitchen sink for a whole-house remodel. Of the various options for a recirc loop (gravity, continuous pump, timed pump, and demand pump), the demand pump appears to be the most energy efficient. However, you still need to hit a switch and wait for the hot water to get to the location of use. You save the water that would have gone down the drain, but you're still waiting.

Drywall Backer Boards

The traditional way to install drywall is to terminate butt joints on a stud or joist. An optional method is to use a contoured backer board allowing attachment of butt joints at mid span between framing. The contour is supposed to pull the drywall edges inward to mimic a tapered joint. The width of the backer board allows attachment away from the very close edge of the butt joint. The subs in my area have never heard of this method. I would appreciate any comments from anyone who has used a "ButtBoard" or a "RockSplicer" backer board.
I'm using 1/2" drywall on walls and 5/8" on ceilings.
