I'm (reluctantly - it's more complicated, and adds batteries to the system) thinking that a wireless RF room thermostat might be the simplest thing to install upstairs.
Reluctance also comes from the price.
Can anyone recommend a make and model, or somewhere that does them at a good price, or both? I'm not interested in fancy controllers/timers, just a turn-up/turn-down type.
Before you start on this route, I'd check you can get a radio signal from A to B. A wireless doorbell or suchlike will suffice. In many houses no problems but in some a total block.
RKM Heating controls
Do you have a subzoned system?
If not, why do you need an upstairs stat?
If so, you should use a programmable one, as you can save a fortune by taking advantage of the fact that bedrooms need a very different heating profile to reception rooms. i.e. you can turn off the heat during the day and only heat in the late evening.
Christian.
Go the T shirt here! I have just installed the Danfoss Randall Wireless Room and Tank stats. They work at 20 metres in building satisfactorily 433.92Mhz The system cost me £129.29 (RMA heating controls) which is a fraction of the cost of wiring (80 year old house) not to mention the decorative downside. The blurb says battery life should be 2 years but I put in some energiser lithium AA cells (7dayshop.com) which means you can forget the problem (almost) One plus is the receiver indicates when each system is calling for heat.
Yes. Three zones (used to be living room and hall on one; downstairs bedrooms on another and "upstairs" (otherwise unspecified) on the third), but since rebuilding I'm going to merge two of them (since the hall and downstairs bedrooms form a new second living room and stairs). Currently all three are running together off the downstairs stat because I don't have anything sensible upstairs.
Well actually even on one zone it would be useful, as the living room gets warm in the evening and the heating goes off, making the bedroom distinctly chilly - so a pair or-ed together would still be useful.
I was working on the assumption that other members of the household would fail to use it properly; but since I'm rarely the last one out of the bedroom on week days, an full programmable one does seem more useful the more I think about it (particularly given the marginal cost).
