Well designed systems can get the best of all worlds and switch to a higher set temperature to do a sterilizing run for a few hours a week, at a time when it is not a problem, and then save energy from leaking away by idling at something cooler for the rest of the time. For an installation of any size where it really matters, care home, hospitals etc it will have been carefully thought about, and such arrangements, as well as hot water circulating pumps and loops to keep the pipes hot to the taps, and minimize waste while running water waiting for it to run warm.
I'm sure there are plenty of buildings, especially adapted ones, where it is not right, but the problems are well understood, and have been for a good few decades. Mike.
