Pretty good. Was 10 quid less a few weeks back but the stand can be flogged on eBay if you don't need it
Tip: Disable 'legionair protection' otherwise the stupid thing will heat your water tank for 2 hours a day even when your away, or the thermostat is off.
Best deal I’ve seen so far for these!

Extra 1% with TopCashback 🏼
I have a Nest and they've ruined it with a recent software update. It's now impossible to pre-heat you house for when you get home from work if you're using away/assist, which means always coming home to a cold house.

They were 150 on black Friday. I'm not suggesting we build a time machine before someone makes that comment, but it isn't the best deal ever.

Hot none the less

You can just go into the app and disable eco mode before you set off

Disable eco mode and you can either set up timing to preheat if fix time every day else manually. And you can even decide for how long you want preheat

Yes I agree. I upgraded to the 3rd generation and ever since then I've noticed this issue. I guess there is no fix yet?
Did it include the free stand though

Nice tip! Where is the option to do this please?
I get so frustrated with seeing the water heating coming on

Make your Eco temperature higher so it doesn't get as cold.
Thanks for sharing, I have just ordered one
In no hurry and waiting for the £150 deal that will never come

I have a nest and have it configured to use location awareness but it still preheats the house based on the at number of hours I allow it to preheat for set in the app. Its not easy to find but it's under 'True Radiant'.
Thanks op, just reserved one locally. Been waiting for these to come down a little.
How much does it cost for installation added on.
I've already got a nest 1st gen, it's wired it, would this be a straight swap?
Hey, how easy are these to fit, wonder if you can self install

For the thermostat itself, no, the mount is different. The heat-link (connected to the boiler) is also different
Is it easy enough to install yourself
I could do with one of these as my daughter has got in the habit of playing with our old school one

I fitted my own by looking around the internet. What do you currently have as a heating control unit? Not so much the thermostat but the actual control unit that turns the heating on and off an certain times of day?

Remember, you have two components to the installation. The Nest Control unit is a replacement for you current heating controller. The thermostat part is a replacement for your thermostat.

Yeah I've found that exact problem and had to turn that off

These are great for old heating systems but there are much better options for modern boilers.

Depends on your DIY ability and your existing wiring/boiler configuration, e.g S-plan, Y-plan, 230v combi, dry contacts, open therm.

Best to download the installation manual and see if it makes sense to you before deciding on the DIY route nest.com/sup…pdf

Make your Eco temperature higher so it doesn't get as cold.


So you need to heat an empty house because the scheduling options are rubbish. You shouldn't need to do this, when I'm not there I want the heating off, but preheated for when I return home. You'd think this would be quite a basic option but not anymore.

If you use auto away and your status away you can no longer set at schedule that will be applied to heat your home ready for when you return home from work. I use true radiant also but this issue is nothing to do with that. It seems that they are slowly rolling out this update so if you don't have it yet it's probably coming to you soon.

Thanks for the suggestion but I kind of expect a smart thermostat to have options to schedule that stuff. I mean I want it to do the same thing, at the same time, every weekday, yet there is no option to schedule it.

I've been on to Nest support and they've confirmed they've changed the way away assist works and this is now by design. It would be worth logging a call with their support, if enough people do that they'll have to take notice and provide some more granular scheduling controls. nest.com/uk/…us/

What are they? I'm probably updating my boiler this year so looking at options now.

Screwfix don't offer installation. It's generally £70 ish depending where you live. The nest website currently have £40 off installation, making it £239 fully installed, which is reasonable.
If enough people tweet /FB them, they will take notice, along with calls to customer service.

Look at systems like OpenTherm or Worcester Bosch weather compensation systems etc they are more efficient as they don't simply have on off ie burner 100% or 0% they use just enough to heat the house rather than binary switching such as these.

I contacted a local Electrician, who is also a Nest installer. He quoted me £122 + VAT to fit the Nest, assuming I bought the Nest myself. I emailed him again, just to let him know that he was charging around £70 more for fitting, than if I bought the Nest and fitting direct from Nest. He didn't reply.
Just got one from eBay for £135 with the 20% off code!

The Nest 3rd Gen is Open Therm and uses the local weather to adjust the CH flow temperature.

Ironic thing is Worcester Bosch do not make any Open Therm compatibleboliers and theyre supposed to be the leaders in the field.

I wasn't aware that the third gen supported OpenTherm my next boiler will too.

As for Worcester bosch they use their own canbus system which does the same which works well but is a closed ecosystem so you need to use their Wave system.

Variable flow temp is a godsend, makes for a much more comfortable temperature stability.

If you can't achieve that with your current heating then these nest thermostats are next best thing.
I bought one brand new and sealed from ebay for under £150 but not including stand.

Still good price!

To get the full benefit though you’ll need oversized radiators.
Just got a vaillant one of these for my ecotec boiler. Main reason for the vaillant was the variable (modulating) function - reducing the output of the boiler as necessary rather than a simple full power on and off. I believe it’s ifttt and alexa compatible
