Hello,

I was wondering whether to put the bathroom rads on a separate CH
zone, rather than connecting them to the upstairs zone. I'm thinking
this way I could heat the towels in the summer without heating the
bedrooms.

Is this a good idea? If so, how would I control the 2 port-valve?
Normally I would use a thermostat but can you use thermostats in a
bathroom? I'm thinking not because of (i) electrical requirements
(unless outside zone 2 or wireless) and (ii) wouldn't the humidity be
an issue?

Would you just run the circuit off a timer? Could I use TRVs or would
TRVs switch off the rad when the room was warm but before the towels
were warm?

Thanks,
Stephen.

AIUI it's 'normal' to fit the bathroom radiator before any control valves
(mine is) such that the bathroom rad gets hot whenever the boiler runs -
it's often used as the boiler bypass. Therefore during the summer the
towels dry when the boiler is heating the HW.
