Update I purchased:

Receiver is direct replacement for mechanical timer, so should be easy
install.


Please update. I appear to have the same setup as you and would like
something smarter without overdoing it.

In particular how easy or otherwise to remove the timer mechanism.

Isolate boiler electrically .... 2 screws to open front of boiler,
hinged panel folds down, 2 screw hold in plastic cover over mech timer.
Remove them, lift off plastic lid ...timer lifts out .... swap over
connections (push fit) and screw it back together.
All in less than 5 mins.
