Appreciated but I have been hoping that isn't necessary.

Not quite sure what you are thinking is possible here.

If run from the CH then the options are goign to be turn down the
other rads and have just the bathroom rad on, and run the CH . it
would be easy enough to rig up a timer switch to run it
regardless of timer/stat settings.. Or as Charles suggests a
separate circuit for the towel rad.

I suppose you could have one of these system that can remotely
control the TRVs but that sounds expensive.

Is the reluctance to use electric one of installation issues?


The issue is that I will probably not have any input to the system
design and installation. There is unlikely to be a convenient electrical
supply that can be used without damaging the wall/tiles/something!

So I am wondering what can be done post installation with minimal
changes. Is there a TRV which has something in common with the taps you
get in public toilets which switch themselves off after a period of
time/amount of flow?

From what David has said, I think that the TRV will be OK - but it
would be very nice if the change of the TRV setting was transient.
