10/21/heating on full tilt! We use Wiser @kezo. Excellent product and put it in myself. I also use their plugs which are expensive but reliable.
Good on you mate, its not rocket science fitting them is it.
The only issue is if you have very old thermostatic valves, where the adaptor won’t fit valves or non thermostatic valves.
Outside temp 12c
