Hi all, I'm wondering if someone can validate my wiring plan for my Nest + Vaillant Ecotec Plus boiler. It's an early Gen1 nest so only does the heating. The boiler is new and the installers were confused by the older Nest so at the moment the Heating and Hot Water both have to be on all the...

I believe I have a s-plan heating system. I have looked in the airing cupboard and found 2 valves. One says for hot water The other says Zone valve but I dont think it is a Y-plan as there are only 2 settings. Am I correct? Here is the wire for my Drayton LP722 Is it as easy...

Idle curiosity really- has anyone ever done the sums to see how long the things take to repay their cost by reducing the heating bills/making the home more comfortable I can see the theoretical attraction but not sure about the actual. For instance, most of the year I'm at home on a normal...

Hi All, Glad to join the forum, so many experts here, well done all. Month ago I have replaced my boiler with Baxi 630 Combi (believe this is a fully Opentherm compatible boiler?), and connected with Nest 3rd generation thermostat. Installer was great, but not good with the new technology, but...

My mechanical timer has started losing time, meaning my heating is no longer coming on when I want it. I assume the timer unit is failing and needs replaced (or is it fixable?) and was wondering what my best options are? I'm tempted by something like a Nest to give me more remote control; can...

Please don't shout. I have read, searched etc but nobody appears to have the same Honeywell as me! Currently got a wireless Honeywell now, so took a look at the box on the wall (coming from boiler) and only seems to have a couple of cables, yet the nest seems to have a fair few sockets and...

Hello all, I'm thinking of buying either Tado, Hive or Nest for my house. I live in a relatively new build 3 story townhouse in the UK with the Danfoss TP9000 thermostat / hot water programmer on the ground floor next to my Ideal Logic 15 boiler, a Danfoss TS2 sensor in the living room. Then...

Hello all, Probably my questions is weirdest you have seen. I have purchased a house last month and moved in. In this house we have a Baxi combi central heating. And I was given a Salus RT500RF Thermostat to control the heating. Now I want to replace this setup with Nest or hive and all my...

Rolling up sleeves and installing the Nest thermostat we treated ourselves to for Christmas. Attached some screenshots of previous and new wiring to check before switching it back on. Anyone able to cast an eagle eye over these to make sure looks right? Black wire is boiler and White wire is...

Hi all, Just wondering if anyone knows if there is a way to call for central heating/turn central heating on without a thermostat? Reason is, I've had an electrician install a Nest for me but I'm pretty sure they've not done it correctly, as now the CH is not working - However I don't want to...

Hi, I’ve just purchased a nest gen 3 to replace by heating controls and just wanted reassurance/guidance with the wiring before I go ahead as I don’t want too fry my boiler pcb etc. I currently have a glow worm 18hxi boiler and a British gas programmer and a Honeywell thermostat that hasn’t...

Few people already posted about installing Nest heatlink and termostat to replace Danfloss tp9000 and TS2 room sensor system. So I thought this going to be a straight job, but I've got some surprises. Basically when I removed the tp9000 programmer in the kitchen I've got 3 brown neutrals on N ...

Hello - I'm a newbie on the site, and I've seen that folk are pretty helpful so thought I'd make my first post. I bought a Nest 3G thermostat and am looking to have it installed. I'm getting quotes for £100 locally and want to see if I can do it myself first. I have already taken a look at...

Hi all, Just wandering is the nest compatible with the vaillant ecotec 838 plus combi boiler? And if so, does anyone have an appropriate link with how the wiring should be undertaken. The boiler is a brand new install with no current thermostat installed. Any help and advice would be largely...
