This Could Have Been A Disaster! - A Day In The Life Of A Gas Engineer 68

- This could have been a disaster! We'd just finished piping up a big system when I was doing a walkthrough of the job and realised I'd left an open end! Had I started filling up, that could have gotten very messy very quickly!
The job itself was to remove 2 combi boilers and instead replace them with 1 system boiler and a low loss header to provide better circulation around the system and let it work more efficiently overall.

Awesome job buddy. Loving the content. Only thing I would say is I would of used a 25ltr expansion vessel. Without working it out to deeply, I just use 1ltr for every rad. And find the nearest expansion vessel larger. But great job mate. 👍
Thank you mate, yeah can't go wrong with too much expansion 👌🏾
very good job chirag could only work out pump overrun through LLH because if 2 motorised valves shut external pump had no circuit unless i missed something 🙂
Yup just through the LLH 👍🏾
I couldn't face tracing all that pipework 😅
😂
Does the boiler need any clearance from the wall?
5mm
Do you ever use automatic filler valves instead of the filler loop?
I've not used them myself personally
@cputilitysolutions they are handy to fill a system while you are venting it and so on.
Blow off from the cylinder wrong sorry 😇
Thanks 👍🏾
System working better than before ? Is it all working ok to best of your knowledge ? Your leak free systems happy your happy customers happy sounds like job well done to me 🤷🏻♂️ well done
Thanks 👍🏾
Excellent job..done well to get that done in 2 days...even long days..sort of job i would dread but also want the the challenge.👍🏻
Thank you! 🙌🏾
What a difference, I mainly do service and repair now but still get customers asking what to do in this scenario so thanks for sharing at least I can give them some sort of starting point when speaking to the installer!! Love customers reaction "woop woop" 😂
Always satisfying when it works out 🙌🏾
Wow you reply to every message. You're a proper youtuber. Good stuff. Thanks for finding the time whilst you do your day job and family life. Onwards and upwards.
I try my best!
Aha I am guessing 2 x ecomax with condense collectors gone I have changed a good few of them over the years... 😂😂
🤣
Nice job the only thing I would have done is put a gate valve on either flow or return to the cylinder, just to tweak down the flow going through the cylinder, will help the heating circulate better and be pushing full belt against the heating return.
Ah yes good shout!
Brilliant workmanship just one comment the house that size surely requires a secondary return pump fitted somehow ? But as long as the customer is happy well done again.
Ideally yes, but we didn't have provisions to run a secondary return unfortunately
Cracking job mate, well explained,
The customers look very happy also,
👍👍🤜
Cheers mate 👊🏾
Good job mate ….when the boiler is circulating within the low loss header I take it the external pump stays off whilst this is going on ? Then when the customer calls for heat the boiler tells that pump to come on ? This may sound silly but how does the boiler know just to do that small circuit.
Thanks mate, so both pumps will only come on when the customer calls for a demand. The boiler circuit will always take the path of least resistance so it will naturally just circulate through the LLH. Hope that makes sense
Great install . Only thing I noticed was the safety discharge pipe. Should be high temp , typically push fit polypropylene or copper. ABS isn't high temp so when the cylinder temp relief opens at say 90° c the pipe won't carry that temp . Not too sure about the condense being run into it . Having said that it looks impressive & one happy punter 👍
Cheers mate 👍🏾
Great job, thanks, what a stupid installation they had, two combi? What was the issue with them that need replacing?
I think the heat exchangers had gone, it was my mate's install so he'd been there initially to diagnose the issues. The system wasn't fit for purpose regardless so it was screaming to be sorted 🙌🏾
Were did u park your van in southall lol 😂
At my cousin's
Nice job mate. I made the same mistake with the return on a cylinder easy mistake i found out the hard way🤣
Always happens when you got so many different pipes to tie in 🤣
Great job m8. Why the 2 combis?
Thanks man, I have no idea why there were 2 combis in the first place 🤦🏾♂️
Wicked piece of work 🎉.
Thanks man 🙏🏾
Awesome job
Thanks man 👊🏾
Great job mate 👏
Nice one mate 👊🏾
Nice job 👏
Thank you 🙏🏾
great job
Thank you 🙌🏾
Whats the low loss header do mate
You actually explain at the end 😂
👍🏾
LLH acts as a bypass and a buffer to stop a system side pump robbing the water too fast out of a boiler causing lack of temperature rise and wasting gas/electricity.
Sadly I come across a lot of double 30kw boilers shoved in and domestic engineers forget that it straddles that commercial line and can't be treated as 2 separate appliances.
I spotted one of the other commenters picked up on the pressure relief, they're correct - the only other ways round it is sizing up (2 or 3 or 4 inch pipe) or look up the temperature rating of the plastic waste pipes for water flow per meter. As if it's fast enough over a short enough distance that's the only other way of doing it. I don't know if the tables are current though or even allowed to be used anymore. If you even know the manufacturer/type of plastic pipe currently installed.
Side note, you can have the condense go into it if the boiler has it's own condense trap which won't get effected (condense sucked out) should the tank relief go.
Cracking install and your understanding is definitely getting up there. 👍
Thanks for the feedback mate and thanks for watching, much appreciated 👍🏾
