Love viewing how other engineers operate. Your a good man bro for taking the time to film and upload. 👊🏾

[@Krunokia]

thanks for this video. its great to see finally someone doing the step by step and not just cutting (usually) the most important parts. you even explained every step. I have Vaillant boiler that has 3 - 4 - 5 terminals both on boiler and current termostat (its Vaillant VRT 230) from which the 3 and 5 are line and neutral, and the 4th is basically the switch wire. So If I understand right in that situation I would just need to connect like you did use current wires for line and neutral, and then my switch wire from terminal 4 I can use as you used a gray wire in heat link (think its in number 3 terminal in google nest heat link). thanks again for detailed video

[@pooroldpedro]

yeah, it's easy enough to skip over bits you understand, but I hate it when people skip supposedly simple bits - I'm usually stuck on something that's obvious to an experienced person

[@jimduggen5634]

Many thanks for the tuition, I have had a Nest for over 12 months!! Yesterday was the first time the water worked independently to the heating! Yes I know I should have got a qualified all singing all dancing Nest engineer to fit it……but I didn’t and after this informative video it’s all working how it should be! Cheers 👍🏾

[@donjjjordan]

I would love to know how you did that

[@abdulrokib6801]

Bro you saved me £120 installation fee. God bless 😊works perfect as explained.

[@charlicarter]

Just want to say thank you so much for this video. We had a new boiler fitted with a new nest, sadly the nest was not turning the boiler on and off as it should after watching your video and checking the wiring I spotted that the fitter forgot to remove the red loop that was inside the boiler. Problem solved! We are over the moon 💪🏼

[@YoutubeHero666]

Just letting you know I enjoy watching your videos you have some good tips. Keep up the good work mate.

[@advancedboilertraining]

Love to hear that. I just make videos I wish I could've seen when I first started out

[@richardhodgson7443]

Great video, glad you are back 🤙

[@advancedboilertraining]

💪💪

[@jensmotmans9300]

Thanks for the video. My ecotec plus handles both heating and warm water. Does that change anything to the installation? As it seems you only use it for heating, right?

[@XAXOXA1]

Thank you very much for this video, incredibly useful. I have a vaillant ecotec pro 24, and a nest thermostat 3rd gen. The one thing I did differently was not to remove the u shaped wire link on "Burner off" connector. It then worked like a charm. I must say, am not sure I understand why

[@TalksInTransit1]

Great video have you installed an Centre thermostat. Where on the boiler would you instal the T1 and T2 cable.

[@davidvanlitsenborgh5321]

Hey thank you for your video! I see I don't have an RT (switch) connection plug in my Vaillant. Does that mean the Nest is not compatible? Thank you

[@MustAccord]

Great video thanks! I need a smart thermostat just for hydronic floor heating. The Nest has fan and cooling options which I would not use, any other simpler alternatives? Also each floor has 7 circuits so I would need to fit 14 connect modules which sounds to be an overkill tbh. Where did you order the nest from?

[@sheriefgerges7789]

Great video and explanation as usual from you

[@DhaniQ-ps9fi]

Have a Nest and want to link it up to a Vaillant eco tech 635 system boiler but already have a Honeywell board installed with loads of wires so don't know where to start. Could get someone to do it but i love to do these kinds of jobs myself and learn along the way.

[@chrish1013]

Always thought it's weird the way you need to use a jumper on the box. Just seems a strange design. Or is it wired differently in other countries / different set ups?

[@donjjjordan]

Can I also control the hot water with this boiler and Nest V3?

[@stevehouse3904]

Where did you buy the cable stripper?, great video, thanks

[@rayc1503]

Google Knipex Ergostrip.

[@Михаиллеви]

Bloomin great for sparkies.

[@macpatel7810]

Hey. Long time no see bro. Good to see an upload. Very informative video again. What make is the electrical screwdriver set in the velcro pack btw. Looks really useful.

[@advancedboilertraining]

It’s a draper screwdriver set. If you go on eBay you can get it for about £35. I literally use it everyday. I always end up buying new sets because I end up loosing some pieces 😂

[@macpatel7810]

@@advancedboilertraining nice one. Thanks for the quick reply. I like that it has 2 slightly different handles.

[@jockster5525]

Good job 👌 thanks for your efforts 👍👍

[@stevecompton7203]

Brilliant video, exactly what I needed. Thanks. 👍🏻

[@KishoThamotharan]

Hi Pal, your video is great. Thank you. Can you tell me how to wire vaillant ecotec pro 24 boiler to Nest 3rd generation Heatlink via Opentherm. Thank you

[@SB03182]

I need this too. I am desperate.

[@Burncash1510]

Nice vid bro! What wiring block did you use for N.L.E terminal

[@advancedboilertraining]

It’s just the normal Vaillant block that comes with the boiler. I had a spare one in my van but for some reason this boiler didn’t have it

[@pog1g23]

Great video! Very detailed and helpful. Quick question, what size mm wire are you using in the video? Thanks!

[@peterjones7658]

How was you able to wire the nest stat from t1 & t2 of the heat link ??. The stat needs 12v dc and I presume that the heat link end outputs 240 v.

[@iain9670]

Cheers mate, I got the link in the wrong place first time! Ha

[@SB03182]

Very nice video. Is there any chance that you create video about connecting Nest Gen.3 with Opentherm Module VR33 and Vaillant Eco Tec Plus Boiler? Please...

[@msangwan7]

hi buddy did you find any solution to this VR33 module. I am also looking for ecotherm solution

[@dionmaynard3869]

for the rt do you take the original one out? Or do you put them both in

[@duncan.g.burton]

Cheers, excellent video. Do yo know if its the same for a Valiant EcoTec Plus 630 ?

[@duncan.g.burton]

@@advancedboilertraining Thanks for your reply. I've come across something that is different in our boiler. Their are 3 plugs that say, "Burner Off", "24v RT" and "BUS" the first two have jumper cable in them. Do I leave these alone. As I read somewhere that one of these jumpers have to be removed. Many thanks for any help you have.

[@advancedboilertraining]

@@duncan.g.burton send me a picture of what it looks like: [e-mail]

[@duncan.g.burton]

@@advancedboilertraining Just to let you know, I emailed a few pictures of the board. Many thanks once again.

[@TheZwevegemsb]

why does my boiler does not have a RT plugin... :'(

[@alan_edwards_404]

Great video pal, just started following, like nest but really like hive due to expandability 👌🏼

[@SanderHertogs]

Do you also heat your normal tap water with the boiler? I have the same and still don't know how to wire the heatlink.. I'm changing the current thermostat.

[@advancedboilertraining]

If you have a Combi boiler then you don’t need to do any wiring for the hot water. All you have to do is open the tap and you’ll have hot water

[@SanderHertogs]

@@advancedboilertraining I have the same boiler.. (EcoTec Pro) but an older thermostat already installed, so do I need to 'De-bridge' the 24v DC clamp? for it to work?

[@advancedboilertraining]

@@SanderHertogs yeah, if you have a thermostat then you shouldn’t have a link in the 24V RT. Take the link out and follow the video 👍

[@phdz9390]

I have a Zaegel Held boiler, it heats the tap water and the heating system, i still don't know how to wire the heat link, did you have this type of combi boiler ?

[@davidvanlitsenborgh5321]

Thanks for the video. My Vaillant doesn't have that RT plug (other than that it's identical). Does that make the Nest Incompatible?

[@erwinmakan4812]

Same question, did you find out?

[@davidvanlitsenborgh5321]

I got it done by a professional eventually. Took hím over 1 hour so wasn't a DIY-job for me. But works like a charm. My advise? Hire a pro@@erwinmakan4812

[@ahsanfaheem5038]

Great Video, amazing

[@veaceslavprisacaru1595]

Can you help me to understand what's wrong, why the thermostat can't find the heat link? Please)

[@train4905]

Brilliant sir thanku

[@TM-bu8hz]

Great video 🙏🏿

[@greentea-jl6ht]

hi mate , this is Nest 2 generation or 3 gen? thanks .

[@joeycomhaire4270]

I'm missing an RT connection on the circuit board. Any suggestions which setup to run then?

[@AxelCSL]

If no RT, use HiVoltage system

[@MrErnogoldfinger]

I have an ecofit pure 825, the circuit board is different but the concept/connection is the same. Sadly the wiring shown didn't work for me. When I turen the temperature up, the boiler doesn't fire up.

[@macgregor6755]

Mam ten termostat i jaką najniższą temperaturę wodę można ustawić? U mnie 55 i niżej się nie da, a jest za gorąca ;)

[@veaceslavprisacaru1595]

Hi,I've made the same conditions but the heat link doesn't have a blue light,it's orange all the time,I've reset but anyway

[@deaosatori216]

Is it illegal for me to have a pop at this if I'm not gas safe qualified

[@pinchers101]

Is a hub required to run this thermostat on the app?

[@aminsajawal3935]

Great video brother

[@advancedboilertraining]

Thanks 👍

[@aminsajawal3935]

We’re are you located brother

[@darrenbrown6779]

Wicked video..

[@joelcoxhead5528]

I have exactly the same boiler and same nest thermostat, installing this way dosnt seem to work, it appears to look at first however once I remove the 24v rt bridge the boiler defaults to 50 degrees flow temperature no adjustable (d005) even through flow temp is set higher (d071) anyone got a solution to this?** found out what the problem was, the old vaillant thermostat base station was the cause of 50 max flow temp, removed it and this setup was spot on**

[@imuluer]

It says dont compatible if the wire has that shape like hair like thin and many. But u connected with no problem? Why do they say that it s not compatible then

[@stillasgoodasnew]

Where are you based?

[@christophery8927]

Can I just hire you to it for me. If your London base message!

[@dannymatona3506]

Nice one.

[@MrAps-jh2qb]

Amazing 👍

[@2mad2bad]

Can you install for me?

[@Warhorn-du3xj]

Shouldn’t be cutting out earth wires, also could have been wired without a link in the heat link. Honestly don’t think heating engineers should be allowed to wire boilers.

[@Михаиллеви]

Thanks for your post . He confused me on this. There seems to be an earth termination point on the back of the nest

[@TMckenzie007]

No we should all call you get out the guy video tosser, go make your own show how it’s done

[@onefortheroad1]

Wouldn’t let most electricians near heating wiring as well

[@Wowwow-wl3kx]

so complicated...

[@brounitobrounzi4481]

Bad filming. Camera moves too much.

[@ivanondov8826]

Good job 👌 thanks for your efforts 👍👍
