Replacement room thermostat.
Discussion
I was the person who could actually get the timer record function to work on our 25 year old VHS recorder but despite my best efforts I can not get the timer function on my Potterton Puma 80e combi boiler to work.
I was planning to wait until the Nest thermostat was available in the UK but I'm tired of waking up to a cold flat so I'm looking for a recommendation for a replacement thermostat that is programmable. WiFi and web enabled are features I generally approve of but as I still like the Nest at this stage all I really want is a good value for money reliable programmable thermostat that can easily replace my Honeywell T40.
Attached is a photo of the wiring of the existing thermostat.
Can anyone recommend a replacement that will work with my existing wiring, won't cost the earth and most importantly, doesn't require a Nasa engineer to successfully program. I'm not a trained electrician but I've happily worked with domestic electrics for decades without killing or even hurting myself, having said that is there anything I should be aware of before tackling this?

Wifi you say? Bookmarked.
You can get them (e.g. http://www.amazon.co.uk/dp/B00649IWXI/ ) and they can be controlled from a web browser, but I don't really want to spend £125 on a thermostat when I'm waiting to see when/if a UK spec Nest thermostat is released.Edited by GoodDoc on Tuesday 19th November 23:16
I swapped mine for one of these - basically the same thing but wireless!
Easy to install although I had to use a jumper wire to connect two terminals which could have been better explained and also supplied really.
It's entry level but it's great, reliable and doesn't munch batteries. I was planning to upgrade the controller too but this is perfect and don't need to over complicate it.
The upgrade for me was the original stat was on the ground floor of a 3 floor house where we didn't heat as it's not really living space so the stat was always set to 15 and the temps upstairs were 20ish and top floor was baking at times... now this is replaced by a receiver box and the stat sits in the living room - whole house is a consistent 21 degrees, upstairs fine and I sleep much better for it!

Ive got the new HIVE system from BG: LINK
It controls both the central heating and hot water. It is extremely good and works a treat. I have found myself using it a lot more than I thought I would. It also tracks your house temperature and can be viewed online. I can highly recommend.
I looked at the european version of NEST but I wanted a system that I could turn OFF rather than just reduce in temp i.e. I did not want the heating on all the time. I also wanted to control the times precisely & did not want the system to 'learn' my routine because my routine changes regularly.
Be very careful if you buy a US nest on line because the operating voltages are different to the UK.

I have the same boiler and the same room stat. I bypassed the timer on the front of boiler and fitted a simple Sunvic 7 day programer near the boiler, keeping the roomstat for temperature control.
Note I'm pretty sure the thermostat wiring is 230v, so any replacement will need to be compatible. As it's a combi the control is a simple on/off function, more complicated stats my not work.

I'm not looking to install anything extra (unless there's a good reason). I'm effectively using the thermostat as a switch (turn to 0 when I want the heat off) and with three wires it looks like replacing it is relatively easy, however as I don't know anything about heating control systems I was looking for a recommendation.Note I'm pretty sure the thermostat wiring is 230v, so any replacement will need to be compatible.

I just bought the Nest having seen one in the flesh at someone eles's place. Even with the remote capabilities, just the styling alone is amazing (I think the compnay was set up by some Apple engineers?)
If you can't wait there are a few on-line places that will show how to hack for the UK systems. It just doesn't support the HV side of things.

Still want a nest but converting a 24V thermostat to work with a 240V heating system seems a bit daunting. I'd normally have a go at things like this, but as I'm not familiar with central heating system, and the consequence of getting it wrong is no heating then this projects falls into the not worth the risk category.If you can't wait there are a few on-line places that will show how to hack for the UK systems.

Went for a Honeywell CM907, straight swap for my existing thermostat. At £70 it's more than I wanted to spend, especially as I'm waiting for a UK nest, but it has the features I want now, and won't require experimenting in a cold flat to get it to work.

Let me know how you get on with that, I've been toying with the idea of swapping my set-up for a programable stat.Went for a Honeywell CM907, straight swap for my existing thermostat.

Heatmeiser do one that is Wi-Fi enabled, but before you go buying - CHECK THEIR APPS! Nothing worse then a decent idea ruined by a s

Nest now include the UK on the latest software update (literally a couple of days ago). The 24v issue can be resolved with a relay I have read. The electrician is here tomorrow so i'll run it past him, that part seems straightforward. It was the lack of UK postcode that was the sticking point ................. *looks across desk at 'Nest' sat in box*

I had read that, but my feet are cold today!You will need to get one that runs on batteries as you dont have a neutral connection to power it, I would imagine a wifi one needs mains power. You could use the earth wire in the cable as a neutral if you really had to with a bit of re connecting as the new thermostat probably wont need an earth.
Why is it in flex by the way, does it clip across the wall of your hipster pad? I would recommend the Honeywell type like this.

or the John guest one

Or the wireless equivalent.

I've got a wifi thermostat on my Christmas list.
Whilst I really like the Nest thermostat it's not available in the UK and secondly it requires a mains connection - I don't want to hack into newly painted walls. This also rules Heatmiser out too.
I've come across Salus IT500 of which I am getting for Christmas £150. No mains connection and comes with remote connection which attaches at boiler, and also device to plug into router.
I've also seen the Netarmo thermostat by Starck but it's not out yet in the UK and only available in France.

(The US version doesn't require a mains-connection) - I though the issue with the UK side was the high voltage from the wiring?Whilst I really like the Nest thermostat it's not available in the UK and secondly it requires a mains connection - I don't want to hack into newly painted walls.

I recently fitted the Inspire web enabled thermostat - https://www.inspirehomeautomation.co.uk/thermostat... and it is great. Installation is easy as it is 2 wires and takes any voltage. I manage it via my Android phone - just don't play with in the pub and come home to a 24degree house... I've spoken to Inspire about enhanced features like named custom programmes and they are working on this for the New Year, but it is great for now.

if you want a Nest, easy option is to wait until they do a UK version
