Boiler staying on
I have a Valiant boiler and Tado with smart thermostatic valve on all rads except bathroom towel rail.
When my system was first install I was informed it is best not to put thermostatic valves on every radiator but keep one clear which is the bathroom towel rail.
Since installing the Tado system I have noticed that when the system is shut down the towel rail stays on 24/7, it never did this with my old controller.
I do intend fitting a TRV to the towel rail but could someone tell me why the boiler is not completely shutting down when it is meant to be off?
Thanks for any advice
