Mate..any engineer who attempts this is a legend in my eyes and any any owner who decides this is the best way forward rather than a more efficient replacement is deluded.
I'm sure labour cost plus parts isn't far off a more suitable replacement.
Allied to the worse part of the job .... getting the system balanced and operating efficiently.
Well done, brilliant upload and look forward to some more real world content
Thank you mate, I completely agree and if it wasn’t part of the customers insurance I wouldn’t attempt it, was a proper pain! Thanks for watching
The customers insurance are idiots If they think doing this is cost effective 😂. Fair play mate 👍🏻.
These boilers had 2 great features the 1st being the flow switch so did not need pump over run but the 2nd feature was the best it was light so easy to throw straight into a skip.
Soo true mate! My heart sinks when I see 1, and I see many 😭
I've replaced around 20 or so. One of the first things I do is open the drain tap on the manifold and use a 1/2" hose. It stays in place behind the PCB.
I find if using a smaller U-guage hose water can run from the thread, down the outside. I also use LSX (swear word I know) on the drain manifold, like you say that red seal isn't too clever and the way I see it it'll last until the boilers replaced.
The worse ones I've replaced are when the return tappings are so tight you find yourself hanging off a pair of steelsons and using 2 blow lamps on it.
I've not replaced many recently as in most cases it's more cost effective to replace the boiler. Last quote I had was for over 500 plus.
Great content keep them coming 😊
Thanks mate, great tit bits of advice there!!
Which boiler did you replace with, I have a customer with one in a kitchen cupboard
Baxi 800 heat only probably a good swap as no permanent live required, very quiet and light
Got one of these in my house, it's a pig so nice vid. Changed a few of them flow sensors, there is no easy way, tight and tough to get out, use a mini bahco socket set. Snapped one once trying to get it out, thankfully managed to pull the rest out.
Yep definitely a pig mate! Got there in the end 😂
Thanks for the video. Been waiting for one of these videos. Great explanation. Would have loved to have seen the installation of the heat exchanger but a good job. Well done.
Thanks mate my arm wasn’t strong enough to hold and film haha, have now got a head cam
Good work mate.
Thanks 👍
I've done 1 , I'll never do another ever again....
Cheers.... 👍
Haha wish I could say the same but these bloody boilers are everywhere 😂
Been following you for a while, nice to see some good real life content 😂. Keep it up
Cheers yasar!! Appreciate that mate, got to keep it real, as it’s never straight forward 😂
Well done not easy job
Thank you! Nightmare jobs
The Baxi poo max/ Prolapse take your pick. The reason being most heat engineers shit themselves when they see them. I changed a couple it's a pig of a job. Great work! The Baxi channel has a few handy tips on putting the trap back look forward to your next video.
Thanks very much mate! Yep sure was a pain 😂 got there though thanks for watching
Like the honesty of the video. I was told my Promax SL had a leaky heat exchanger but on further inspection it looks to be weeping from the manifold. In your experience is this a straightforward thing to change? Been warned about bolt being fused to the exchanger so impossible to remove without snapping. Whilst I understand it's not the best boiler, it would be a shame to ditch it for the cost of a gasket...
Blue seal on the top of the heat exchanger is a pig to replace too, over time they just turn to dust....
Yep they definitely do! Flue out and everything
Just been to one requiring a new fan, it had a water around the bottom of the casing which I assumed was the condense and now it’s struck me the heat exchangers leak. 😳
Uh oh, good luck repairing it, or changing it
I've had a couple of those condense trap plastic nuts just disintegrate as soon as they are touched.
They’re an absolute nightmare them traps!! 😢
On a combi boiler can you replace heat exchanger with touching the return and flow valves as they are prone to leaking. Is there a way to create a vacuum if yes how so 🤔
Hi mate, there’s not a way you can create a vacuum on a combi system but sometimes they will airlock to allow you to work on it with minimal draining
My honest opinion if your worried about the valves then just drain the from the boiler until it stops
@@snapgas9832 yeah must be airlock technique but like you said better to do proper way.
Hi
Just a quick question
Is it safe to use artificially softened water with this boiler?
Also is Corgi inhibitor compatible with softened water?
Cheers
Would havebeen hassle filling the very big system back up bleeding all rads and get it running
Yep usually is mate but that’s part of the job
I’ve done that job once it took over 4 hours could of slung new boiler in an hour swore I’d never do it again and actually walked away from two jobs since refusing to change the heat ex horrible horrible job
the heat exchanger had blew side seals because the service engineer didn’t clean the magna clean out it was full of crap
Yeah Daryl they’re horrible to do mate! Took me 4 hours too
Even the Baxi guys take 4 hours!
They all hate it too
Wish I could walk away 😂
can you post details of the ratchet ?

Looked a pain next time let baxi do a fixed price repair 👨🔧 😅👍
Bloody insurance policies mate! Have to keep them going 😢
From where I can buy this ratchet.
Thank you

Have you tried bunging the tank mate to speed things up?
Was a sealed system mate or if of loved to haha
3 story property and I’m on ground floor 😮😅
@@snapgas9832 Fair play mate them boilers are a pain to change exchangers and flow sensor 🤮
Video was so rubbish not good at all
