Hmm, interesting.
I live in a place where hot water is either from a continuous flow heater, so basically no extra circulation; or from a small under-sink water heater where the water is kept at safe temperature and the distance to the tap is near zero.
But I guess in places with these big, central hot water storage thingies what the article says makes sense.
