Another thought is to use a series of Esp8266 devices with rwlay and temp sensors (somebody must have done one), and then central control from a PC/Pi over wifi.

Bonjour !

I have finally found a use for a Raspberry Pi...! Since moving to France we
have ended up with a house with stupid electrically heated oil filled
radiators. They are not properly controlled and quite inefficient, at best you
can control them on a thermostat but there is no clock...

It seems obvious that all I need is a thermometer, a mains relay a Raspberry
Pi and some some software to create a time controlled thermostat that I can SSH
into...!

So I think I need
a box
a AC/DC transformer for the Pi
a mains relay
a digital thermometer
an override switch
something to mount the relay and transformer on
WiFi Pi or WiFi module for Pi depending on model

I think this is technically easy to do, but the biggest constraint seems to be
that the overall box needs to be small and "wife friendly"...
