While I've often wondered why, and sometimes thought of designing a

There is/has been an "open standard" via a manufacturer consortium in
Holland to attempt to produce a common control interface between room
and water themostats and controls and single or multiple boilers,
basically to provide something better than coarse on/off control via
PWM.

I can't find the link for the moment, but a few of the well known
manufacturers had joined it. IIRC though, little had changed on the
site since about 2000 so it has probably gone the way of most
manufacturer consortia...........
