Vaillant EcoTec Pro - How To Change / Remove The Main Heat Exchanger (F76 / F72 / F24 / F23)

- REASONS WHY YOU MIGHT NEED TO CHANGE / REMOVE THE MAIN HEAT EXCHANGER:
- The first reason why you might need to change the heat exchanger could be that it is leaking. If the heat exchanger has failed then it could be leaking water into the boiler or through the condense pipe (your boiler will keep losing pressure).
- The second reason why you might need to change the heat exchanger could be that it is blocked up. Over time the metals in the heating circuit sludge up (combined build-up of rust and dirt breaking off from copper pipes and radiators), it is possible for this sludge to block up the heat exchanger. If this were to happen the boiler would keep over heating as the water is not flowing properly. Sometimes when the boiler is operating you will hear loud banging noises coming from the heat exchanger. If the heat exchanger is blocked, you can try take it out and flush it through or you can replace it.
- You could also get some of these fault codes coming up: F76 / F72 / F24 / F23
Hope you learnt a thing or two from the removal of the heat exchanger of this Vaillant Eco Tec

Believe it or not..this guy posts some of the BEST Boiler videos on the net...Well Done bro...
Thank you, That means a lot! Hope you’ve had a great weekend🔥
Decent video 👍
I followed this video to change my friends heat exchanger as I'm a installer I haven't got much experience working on fixing boilers, helped me out massively 👍
I'm new gas engineer, I ended up on this video and could do nothing but subscribe, thanks a lot for sharing this!
Yes mate, this is going to be massive help. I'm a few weeks into being out on my own doing service and repairs and I have one of these to do tomorrow. Cheers geez.
Thx Man, nice refresher.Haven't done in 2 years.For others, last time i sprayed Wd40 on the seal on the top of the old exchanger to pull out easily.
What a legend man in heating industry
Great job . I have same this boiler vaillant and I was wondering how to open it . Thank you very much

Thank you. Great video. 👍love it
Thank you Rajesh! Means a lot 👍
Great video 👍
Glad you enjoyed it
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
Nice video bro
Thank you!
When you put a new one on do you take the plastic off at the back off the hex
Sorry, my mum has no heating and its a Valliant boiler with a F2 error code. We were led to believe this is to do with limescale build up. Is this correct?
Hey do you mean F22 on a Vaillant?
Always fit a new H/EX to flue elbow rubber seal as the existing one will probably be past it's sell by date.
That boiler is same as mine I got a leak and it's the divter value leaking but I got British Engineer coming in tomorrow too fix it
Hopefully all goes well 🤞
@@advancedboilertraining update it's was divter value carttriage And no more leaks👍
