RE: Zoned Heating Control
Should not be a problem as most TRV valves are constantly cycling in
any
case with the conventional head fitted. Some TRV valves from the likes of
Honeywell and their rebadged resellers have a replaceable valve insert that
can be removed for cleaning or replaced without draining down the radiator.
The more likely problem is that the valve sticks or gets clogged because so
few people keep the heating system topped up with inhibitor

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?
