Wireless room stat questions

[keithwalters]

Hi all

How do wireless room stats work? I know they have a receiver box sited near the boiler - are they wired directly to the boiler (and also a permanent live supply themself) - and when the wireless room stat requires heat the signal to the receiver sends power to the boiler ?

They seem to be very popular these days and I've read a bit about them, I haven't got a room stat with my combi, so was thinking of getting one fitted. Are they expensive and reliable?

Sounds like you know how they work already.

Yes, pretty reliable, usually just batteries in the stat/transmitter that need replacing occasionally. You can get ones that are just a stat as well as ones that have an inbuilt programmer to control heating times.

Stick to reputable brands (eg Danfoss, Drayton or Honeywell), and stay away from cheap brands that you have never heard of on Ebay.

ok, thanks. I've read a bit about them but have heard they can be problematic and have faults.

Is it possible for me to be able to fit one myself? I have a fused switched spur unit next to my combi.

Personally, if the building layout allows, I would fit a good quality hard-wired stat. These are the most reliable. Wireless aren't quite as reliable due to the fact that they are more complicated in construction, and have 2 units. I only use them, if running a wire from the stat location to the boiler is going to be difficult. Just get a good make.

If you can do basic wiring, it shouldn't be too difficult. Its only 4 wires.

Post again with your boiler details, and the stat you want, and someone on here will tell you how. If not, get your friendly local plumber to do it for you.
