Go for a smart system, we have Hive and each radiator has a smart valve except the bathroom. It is possible to heat just one room or as many as you want and we can do it all using Alexa.

Conceptually I like the idea. Does the system create a "demand
for heat at the boiler" as long as any smart valve needs it?

What kind of cost are we looking at for a full install in an
average property? Not sure if the payback time is reasonable.

I hope your Alexa makes a better job of it than mine does of
recognising music I am trying to ask for. The frustrating aspect
is that there is no alternative interface.
