NEST thermostats

Interesting, it controls the boiler via a WiFi link. Not how the US one works.

Surely it's just similar to how an existing wireless thermostat works? The one I have may be RF rather than WiFi, but it still requires a hard-wired box sat next to the boiler to tell it what to do.

US heating systems are pretty different from what I gather?

That my point, doesn't seem to work like the US one but it UK competitors.

The EvhoHome way to expensive, it very tempting. The Hive just lacks that WoW factor.
 
I've just ordered one! The free installation swayed me.

We currently only have a 24h timer for our heating so anything would feel like an upgrade!
 
To be honest the only reason I would get one is to increase the saleability of my own house if I was looking to move. I'm sure seeing a Nest-equipped home would look good to any buyer.

I doubt anyone would pay more or even buy a house they wouldn't have normally because it has a fancy thermostat. Being excited over a thermostat is a very rare thing.

The appeal for me is:
1) I want to control the temperature of a room that I use rather then the hallway, so would be moving my stat anyway.
2) It looks good
3) It turns the heating on to be at a prescribed temperature when you want it. Get in at 6pm and your house will have just clicked onto the 20 degrees you have set.
4) At the moment, during the winter I just leave the temperature set at the same value 24/7 because I don't understand the boiler controls...
 
tempted. been reading reviews about this and all seems good.

However just seems to be one thermostat, so if it is in the hallway, my bedroom could be freezing ??

Not pay more no, but the appeal factor over something like this may sway a buyer over another property. It certainly wouldn't do any harm. A newer, shiny gadget that is the latest "thing" in heating control would surely look more attractive than an outdated thermostat.

Lol, yeah. You'd probably see a lot of benefit then. People who see the most gain in something like this are probably similar to you, over-zealous with heating or just don't set it correctly with existing controls.

The only reason I'd buy one is it simply looks great. I've got my heating setup how I like it abd timed perfectly so I wouldn't save a penny with this, still eventually might pick one up just for the looks.
 
Tempted, might get one as the introductory price inc fitting seems great.

Just moved in to our first time buy and i've got it on constantly low at the moment as I haven't had chance to figure out the programmer. In our previous rental we had one of those old 24 hour ones with the on/off pegs, replaced by a week day / weekend programmable a few months before we left - neither of which I could be bothered to mess with very much so always ended up either a bit too cold or a bit too hot / things coming on at the wrong time.

This seems a bit more "set and forget" and I like the idea of being able to tinker from my phone.

umm.. might be obvious but I haven't got a thermostat attached to the wall, just a wireless ones which i leave in the hallway.

So how would Nest work in this scenario ? As the install guides i've seen show the wall mounted thermostat being replaced with Nest ?
 
The NEST is still my go to for this and the free fitting makes this way up there. Thing is, it's a pointless time to deploy this and see the benefits (no heating on this week so far).

We don't have full TRVs yet either.

Question then, we have a boiler in the kitchen with no box near it. A thermo mid floor and a timer box in the airing cupboard top floor (which allows us to program CH and HW twice a day and extend, on, off, advance as required.

Where does the NEST fit in terms of flexibility? ie, if I wanted to whack the heating up via the NEST, how will it turn on unless the timer in the airing cupboard is permanently set to "on".
 
Now it is wireless i am back to being interested in this, knowing its ex apple people gives me hope it will work well and have a good ui ;)

Hmm, very tempted indeed.
 
I've organised my free install, you have to pick 3 days in order of preference 9am - 1pm or 1pm - 5pm

There was no mention of which approved installer will attend just that I'll get a call in 2-3 days to arrange specifics. Other than that they want to know your boiler type, make and model.

I looked at the approved installer list before ordering and the closest was more than an hours drive away so I'll have to have the kettle on when they turn up :)

your timer will become redundant the nest does everything, except for the hot water
 
Tempted by Nest, but have some niggles stopping me from ordering.

My last house has a Honeywell CMT927, which worked pretty well, as we have a relatively fixed schedule (but not rigid for all days). Just moved house, and the boiler here does not have a thermostat... just on/off at set times using the digital control on the front of the boiler. Therefore I was going to get another CMT927 for full on/off control and wireless thermostat.

Nest looks very interesting, but I need to justify the price difference over the CMT927, including the extra functions that Nest offers. Nest has learning, auto-away and wifi; however, CMT927 cost £120 new or £75 from auction site... compared to £179 for Nest.

I really like the idea of the Evohome: the Base Pack (main controller, stand and relay) is on sale for around £190, which is reasonable compared to Nest; but my house has lots of rooms/radiators, and we would need at least 6 (if not 8) radiator controllers... at £60 each, that's £360+ on radiator controls! :eek: I can see that becoming a £600+ install.

One thing really putting me off Nest is that you have a modern, good looking thermostat/gadget fixed to your wall, with an exposed power cord dangling down with a plug at the end that is simply plugged into a wall socket!!! I don't know if the free install options includes hidden wiring if it is not already there from your previous thermostat.

I'm thinking to spend £75 on a CMT927 now, and see what options there are in 3-5 years.

Thoughts, anyone?
 
That CMT927 has quite a few 1* reviews on Amazon: http://www.amazon.co.uk/dp/B003DTG65I/

I say either go for a cheaper (but more reliable) Honeywell stat or go for NEST if the Evohome is out of your price bracket. Have you considered getting Evohome with just a couple TRVs to start with and add more later? You seem to be content with spending money again on it in 3-5 years.

I wasn't aware the NEST had a power cord with a plug on the end. I thought that was just for the optional stand. For wall-mounting the wires should be hidden behind it in the wall I would've thought.
 
I had the CMT927 at my previous house for a couple of years and was very happy with it. At £75, it is significantly cheaper than Nest, and doesn't have the wiring issue, as it runs on batteries (didn't need to change batteries in the 2 years I had the last one). The one star ratings all seem to be due to issue of the screen fading.

In 3-5 years, I think the like of the Evohome will become more mainstream, and the prices will drop significantly. I used the planner on their website, and it said my install would be £1000!!! I'm happy to drop £75 now, and then get a system like the Evohome for £300 in 5 years time (wishful thinking?).

Regarding the wiring for the Nest, they recommend using wires in the wall if they are already there, but not for a new install (see below):
