I'm looking to get a new combi boiler fitted soon, likely a Viessmann. The combi boiler will be servicing about 9 radiators (including 2 towel radiators) and 2 showers in a 3 bed flat. I'd like a smart thermostat system for this, but am a bit flummoxed by the options especially the zoning...

Can't find an identical problem, so here goes. Nest v3 installed in the summer, by my local gas engineer. Don't want to bother him again as he took pity on us and charged us an unbelievably low price to sort out many issues left by a previous cowboy. Heating and hot water are on a Y plan...

Hi All I have had a search through previous posts and google, but everything I find seems to get me more confused. I have just had a new Vaillant boiler fitted, an ecoTEC plus 838 combi. It is just the boiler at present, operated by the controls on the front only. My plumber is offering to...

Hello all, been a frequent visitor here for lots of tips over the years, but this is my first question. I would like to upgrade my Drayton digistat 3 (central heating) and separate Drayton LP711 (hot water) controllers to a single Nest system that controls both CH+HW. System is open vented...

Hi, We have just moved in to an old property with a Ideal Mexico 2 boiler controlled from a Horstmann Potterton controller. The timer function has just stopped working and I thought I could upgrade the potterton controller to a Nest thermostat with heat link. I think the Ideal Mexico 2 is a...

Hi All, Looking for some advice regarding the compatibility of a Google Nest to replace existing Drayton timer and stat. I know the Nest is compatible with my S Plan system generally but cannot see how I would wire the new stat into the T1 and T2 ports on the Heatlink (which is a 12v...

Hi, I.m looking to add a Nest Thermostat E to my Alpha Eco Boiler. The boiler has no room stat but just a timer. My understanding is that I should leave the timer in and set it to always on. I should then remove the link connecting 1 and 2 and run instead two wires from 1 to NO/Call for heat...

I've just installed a Nest E in place of our old thermostat and it doesn't appear to be working correctly. The Nest E and the Heat Link both communicate with each other fine but when the power is switched on at the mains, the boiler doesn't power up. I've attached a photo of the old thermostat...

Hi, Hoping someone can help as I have looked everywhere without success. My setup... I have a fairly new NEST setup that controls hot water and central heating from a Valliant ECOtek plus. I have a megaflow in the loft (probably not relevant). All radiators are on a single circuit. What I'm...

Hello guys, My name is Marian and I got an Worcester greenstar 25i erp combi boiler. I need your help to install a Nest 3rd generation also can you help me to find right washers for connectors between wall support and boiler itself? (CW, HW, Gas...etc) Thank you so much for your help. Marian

Hi guys, New here. I have a nest E thermostat which I've put in replace of a honeywell t6360. I've wired this is before at a previous address with no issues. However this time round no matter what wires I put in what place the heating stays permanently on. The nest thermostat is on the off...

Hi, I'm not sure if my programmer can be replaced with a 3rd gen Nest? Google website says my wiring means no, but I don't believe that's true. Do I need to modify any wires or add anything? I know there's threads discussing similar, but I'm still not sure. I have a Drayton (British Gas UP2)...

Hi All, This may have been asked before, but I need some help wiring up my honeywell 2 port valve to my heatlink, after some dodgy electrician was useless. This is the current set up and, the zonal valve stays open constantly, so when the UFH is live, so are the radiators: I can see...

Hi Everyone, I have replaced my existing Myson MEP2C with a Nest 3rd Gen. Everything went well, except there seems to be no power to the existing stat where I was planning on hard wiring the new Nest thermostat. Here is the wiring setup before at the conrol where: 3 = HW on 4 = CH on Here...

Hi everyone, I'm planning to change from Nest to Hive. I've read a few posts already (this one in particular was helpful) and I'm fairly confident I've got it right in my head, but a few things I want to check if you could help. Bit of background - we moved into a house with a system boiler...

I recently installed a Google Nest doorbell along with a Surf 2 Note Door Chime and a 12V doorbell transformer from TLC, and noticed the Surf 2 Note Door Chime is very quite when rung. Yes, it is wired correctly and has the module installed inside the door bell that came with the Google Nest...

Hey folks, I just recently moved to the UK and the way heating systems work here is new to me - apologies if this is a dumb question. In my current flat, I have an immersion heater which consists of an unvented indirect cylinder (TI120P4) for both hot water and underfloor heating. This is...

I’ll try to keep this as short as possible! Basically the timer has died on my Ecotec plus 831 combi and rather than just replace it with similar I was thinking now maybe the time to go smart and get something that can help my heating system run more economically as we’re off grid so run off...

In the attached photos you can see the wiring and wiring diagram of the receiver I am looking to replace with my Nest Thermostat E Heatlink. My question is around the Common connection. As you can see I have a jumper from L to COM. Am I correct to believe that I should use L (brown wire) as...

Hi Looking for some advice....I have just purchased a Nest 3rd Gen and are looking to install myself. I have a Honeywell ST9400C programmer for heating and hot water positioned next to my oil fired Firebird Combi boiler. I also have a Honeywell room stat. I have photographed the existing...
