    I have a combi boiler with an adjacent standalone timer both located in my bedroom and also a single thermostat which is located in the entrance hallway of my flat. The thermostat has stopped working and also the timer has limited functionality. I have standard radiators in each room, all of which have TRVs except the one in the hallway next to the thermostat.

    Can I replace the thermostat with something that would be both a thermostat and a timer so I can solve both problems? What types / models would people recommend? Also, is it likely I can use the existing wiring and the installation will be a quick swap or will there be other things involved in the installation?

    You can get wireless thermostat/timers in combined units, though I do see lots of people strugging with them in practice when I'm out on installs.

    I also have a view that room-by-room (zonal) control will give you better savings / comfort for your money.

    Not having to program in detail per room (eg self learning) is likely to lead to more enduring savings (eg see US EPA and programmable room stats).

    My suggestion would be to get a very simple thermostat/timer, or a pretty thing like a Nest, in your hall for gross on-off control of the whole system, but do the fine-tuning for comfort and savings per-room.

    All a programmable room thermostat is is a battery operated switch this can then control both time and temperature can be a replacement for the thermostat

    If youre happy with the temperature control that thd old thermostat in the hallway provided, then just replace the old stat with a programmable one- no wiring or plumbing changes to fit the new stat. Set the old timer to permanently on or remove it and the new stat will control the heating at the times and temperatures you set. We have a number of Honeywell CM907's and I find them easy to use and they allow different programs for each day of the week, but theres a wide choice of alternatives available.

    Rats, am going to have to search through your posts now....

    Took me ages to find it - RadBot :bigsmile: If I had radiators I'd get some of these. Might even do so for my Mum.
