So the kitchen/diner is L shaped with the kitchen the larger and the dining the skinny off shoot.

Radiators are placed as indicated, the kitchen one in fairly close proximity to the proposed oven location.

The kitchen is north facing, the dining areas south facing but with a smaller window.

Should I:

Treat the rooms as a zone, if so which radiator to bind first?
Treat the rooms as a zone and install a thermostat to control it if so place it where?
Treat the room as 2 zones and let the TRVs sort things out?

Any help/ideas appreciated.
