IMPORTTANT: Do not overtighten all nuts where pins run through, as pins would get stuck and the boiler won't work and will give low pressure/faulty pump error. Apart from this, great video, thank you!

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.

is it the central heating flow and return you are emptying

If you’re doing the shower hoaky coaky replace it don’t bodge it

Exellent😊

Cutting off the earth naughty boy 😂😂

What do I need to do with the boiler mechanical timer dial?

This is an excellent video welll done!!!! Communicated very clearly and showed every aspect required!! Excellent!!!! Thank you bro!!!❤❤

You havent explained how to use the control and what does "actual" and "target" mean .

the advanced assasins creed walking had me

Instead of this I just soldered onto the backs of the existing lights to hijack power from them (and retain the existing switch functionality) and ran to the strips from them, and removed the lamps from those two lights so just the strips produce light now.

Any chance we can fit a filter somewhere to stop this blocking mine gets blocked every week even we powerwashed it

Awful boiler Will never fit again

My diverted valve leaking from pin,what could be causing this,don’t fancy getting brand new valve if I can get new seals for it

wrong tamplate was supplied

Top video, I struggled to get mine to connect. Hive were less than useless, wasted hours trying to pair up components. After watching this video. Sorted in ten minutes.

I don’t have connection point at RT, what can i do now?

I want rid of my hive and install a wired stat!

hello, I have a vaillant ecotec plus vcw 346 3-5 boiler that works with natural gas and I would like to run it with propane gas. Thanks a lot

Is this a forehead camera? May I please have make and model?

I need to do this on my glow worm the part was only £40 so going to give it ago changing it

Really informative video, I checked my diaphragm and it looks ok but 6 out of my 7 hot taps start the boiler the other one doesn’t push the pin out far enough to close the microswitch , also 2 out of 3 of my showers are the same, any ideas?

Thanks

Geeza

Well done mate .. nicely done

Are there the holes at the top to put the chemical in case of blockage?

If the waterways within this heat exchanger are blocked can you clean them better by taking it off? Somebody told me you could even try to pressure wash it

Hi we have this boiler and were getting hot water but no heating, put new automatic wireless thermostat thinking it was that put still wont start up unless in engineers mode what do you think is wrong 🤔

Excellent video!

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

Hi Did you ever make a video on taking 'the right hand block' out? (water pump?) My flow sensor is not coming out for love nor money, and as you have shown - access to it is not great. I've bought the tool but all it's doing now is slipping on the brass top of flow sensor. Thanks

The hand motions at 14:56 was absolutely mind blowing

Really good work mate, fantastic video explanation 🫡

So just to get this right: 1. We isolate the flow and return 2. Drain the boiler 3. Isolate the cold inlet 4. Leave the hot pipe as is 5. Open hot water taps around house to check all hot water is out of the system 6. Remove heat ex plate Is that correct?

If there is a pin hole and you say the pressure in the boiler will always be going up, would that be when the heating is on or even without the heating being turned on?

Hi I paid for your boiler training, But I can't find a login button now. Can you help please

Best video thanks😅

Top vid mate❤ very well detailed.

Cheers boss. Great video as usual❤

Thank u.

How can you make a video right off the bat saying you take your wee pack in for a p/p only…..then 2 mins later say you take your foot pump in for 90% of your repairs - 😅😅😅😅

Great video, if I was connecting multi zone. Would you recommend setting up one stat and then add the second heating/hot water stat via the app. Or do it all together

Great accurate content as usual❤. Thank you

That is a top in depth video as usual❤

This was quite an interesting video. You proved experience and competence❤. Keep em coming

A very interesting video❤. Thank you that was quality in depth video. Nice pipework buddy.

Good job buddy. ❤. Never a dull moment in your vids. Thank you

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

A top quality video. ❤. I love how much detail you share. Thank you.
