Yeah, that's it, thanks. It's a bit pricey. It also seems to involve continuous circulation, which results in continuous wasted heat. I'm not interested in instant hot water. Rather, I don't want to waste cold water into the holding tank while waiting for it to get hot at the tap.
If a system like this worked on demand, rather than continuously, cold water coming out of the hot line would run back into the cold line. You'd need some way to know when it was hot, since it wouldn't be flowing out for you to feel it. A thermometer, maybe?
