One thing I've been wondering about these kinds of add-on valve motors,
is that most standard radiator valves don't look like they're built to
withstand contant twiddling by a computer.  I can easily imagine them
wearing quickly, even starting to leak, after a couple of years of
continuous adjustment.  Or am I just being paranoid?
