My goal is efficiency - you’re only running the boiler long enough to heat the radiators that are actually turned on, right?we have a honeywell system here - wireless TRVs talking to a central controller. it's dead handy - you can set all sorts of schedules and thresholds for each room.
right now, because the lads are still working here (they're finishing the wiring in the kitchen) with loads of doors open, i'm sitting at my desk with just the rad in this room on, using the manual override on the TRV.
