Brilliant video, great to watch. Once you'd diagnosed the governor and had it changed I think a lot of people may have seen the boiler to appear to be running normally and called the job a good 'un, but you carried on and made sure the combustion was fine before leaving site - impressive work ethic and a good example to others.
Thanks. You have to be sure its all ok. Especially as so many others have been there. They could of tried to adjust the gas valve and messed things up even more.
So the boiler was fine, what you did was amazing most engineers would come in and say they need a new boiler and still would of had the same problem lol
Most people see an unusual or rare boiler and panic. So its easer to say a new one is needed than take the time and risk getting it wrong. I like to work on boilers that are new to me as long as there is no time constraints. Thanks for the comment!!
Top notch! Thanks a lot for taking the time to video this. Like the long, beginning to end, boiler fault finding videos. Real world stuff. Just pull up a cold one and watch a master at work.. Please keep them coming!!!
Day off ...spent it all day watching your vids 😩. Another cuppa tea and waiting for the next one too load ...busman’s day off ...wife thinks am sad.😀. Having a ball thanks heating geek
Nice work. Shows the importance of doing the basics! Also like you said, standing back and actually observing it was a combustion issue and keeping it simple and not looking for faults that don't exist, On the face of it you can see why a plate was changed as you'd get similar symptoms I guess. Always check the basics kids... Good work man
Your videos are so cool for someone like me new in the business .Thank you for spending time doing them .I think the ratio of 0.0017 is greater then 0.003.
@@HeatingGeek It is all good .I started this week as brake down engineer and repaired 6 boilers out of 6 so far thanks to you .Most of them war just very simple to diagnose but still ... I wish i know more about the multimeter .All the best and keep it real.
Yeah if you look in the Vaillant Turbomax plus manual it shows it. I have been doing it like that for about 15 years. Weird doing it on a modern boiler.
It alters the gas pressure based on the air flow through the appliance. It will adjust slightly as the boiler becomes dirty and/or the fan becomes lesss efficient.
you was right to think the flame picture was not good, at 9.7 co2 with case on the burner is running fuel rich, an adjustment of the air gas mixture would have brought the co down and improved the flame picture and efficiency (all be it marginally). That's why co2% is just as important as ratio, because m.I's say ratio is ok so appliance is safe which is right in theory but it still would have benefited from calibration to get the most from it. Although we all know in real life and with more jobs to get too that as long as it's burning safe rather than efficiently then it's job done and crack on to the next one 😁 Good vids btw.
Im doing commercial in a few months so I hope to learn a lot more info on combustion and efficiency. At the moment I just aim for the MI's and that will do!! I think all Manufactures need to standardise the combustion set up on there boilers. Too many different boilers with different procedures.
Sadly your video highlights than many engineers out there may have their Gas Safe ticket but you wouldn’t trust them to light your blowlamp but I’ve seen worse, a young pregnant mother & two year old left in the middle of winter for several days with no heating or hot water as a part was said to be required when all it turned out to be was the gas meter had locked out
Another superb video ' which do you prefer using with the mannometers? I've just bought the regina 45 premier Love to see you do more of testing electrical components at the pcb ' if you ever get time 😊
Did they replace the governor on the meter ? i had this done because of low gas pressure after first service even though the previous year the council arranged a boiler swapout nothing was mentioned by the installer at the time of install so along comes first service and a gas pressure problem governor was changed by cadent boiler was serviced and is running makes me wonder how lazy the original installer was funnily enough this also rectified a gas cooker upper oven issue where the oven kept going out and had sent two new cookers back because of this problem seems many technicians are not as thorough and skilled as you
Any tips on screwing flues? My most hated part of the job, I’m scared of going through with the hss bit ! I’ve taped it up so only a little the tip of the bit shows but it’s not ideal, any better solutions I’m all ears ! Nice video, basic checks seem to evade most
I use self tappers that cut there way through so I don't pre drill. They are called self drilling screws and have a little flute on the end. use a cordless and takes 10 seconds to cut through.
Whens next video mate? Really learning from them. You are very good with multimeter to prove faults. Must be hard filming too and probably takes double the time to then complete job but it's not appreciated 👍👍👍
HeatingGeek yes. I was going to say that I like to do it with the case on to see it perform in normal working condition, that way the air intake is via the flue instead of the ambient air if the cover is off, there may be a hole in the flue inner for example. Many colleges over the years don’t do this even training instructors on courses do it with the cover off. Makes no sense to me. Thanks for unloading this videos I don’t work in the gas industry anymore though I still hold a license and it’s good to watch you go through the faultfinding in your vids so I don’t loose touch with it.
New follower, great videos how do you find the time! Noted a plastic cap on top of that gas meter regulator; I take it was a 'Donkin'. I always report these to the network when I come across the Donkins with the black plastic cap as they have pressure issues as you have so clearly demonstrated. Great video.
Good morning My gas boiler has a problem I set the heating temperature to 45 The boiler does not stop and the temperature rises to 70 degrees Where is the problem Thank you
Another great video' could you do a video about how you got into heating and gained your experience also on any other tools you think could be useful. DAMM that's Alot to ask.
I constantly try and monitor what tools I use so I can empty my van little by little. Thanks for the video request. I will try and do it in the next few weeks.
Hi. I have an alpha CDC35c and when running a bath, the flame is lit for a time then goes out and water runs cold then flame starts back up then sister goes back hot. This is a constant cycle. A plumber changed the gas valve last year, as he said it had a small leak. Any ideas why water keeps going cold then hot etc? Thanks
Good morning, i recently qualified as gas engineer. i have been watching your videos and thank you for sharing your experience. i really want to know if i can come and train with you? Thanks

I don't have a website (might have soon). I live in Cheshunt in Hertfordshire. It was a long drive but by no means the furthest I will go to fix a boiler.
The same engineer several times. Rushing. He got the arse because it was someone else's job to begin with. Most issues are caused by rushing. Companies need to understand that fixing boilers isn't always as simple as this one.

Thanks. :-)
Ho do you replace selector switch? Just pull out from front panel?
how long was you on this job from start to finish, i know its not a race , just curious.
great work ethic by the way and very thorough.
I really don't know. It was along time ago. Maybe 3 years ago.
Great Vid so what was the Gas rate ?
6 years ago. I have no idea. Did I not show it?
Great as usual . What is the purpose of a pipe on connecting differential to gas valve . Thanks

You get high and low settings for co2 by adjustments on pcb

Had that a few times when I used to do social housing. The firm I work at now are usually very good. Everyone makes mistakes though.
Even me. Hopefully I will have the nuts to upload it when it goes wrong... Time will tell
Top class engineer! Hats off to ya lad!!
Thanks a lot :-)

Good video as always mate ...whats the script with the differential burner pressures on these boilers ?
Im not to sure myself. I didn't pay enough attention when I was looking inside the boiler. It was correct and that was enough for me!!
Great video plz do some more cradle to grave video's
If anything interesting comes up, I will. Thanks for commenting.
can you tell me why the red light on fuses A and B stays on
this morning I had hot water and the hot radiators are no longer heated

Been on holiday this week! Have some footage somewhere. I will get it edited soon.
Brilliant vid mate!
thanks :-)
I’ve a question. Do you usually do the gas flue analyser test with the boiler cover on or off ??
I always do it with the cover on unless I'm setting it up. Once it's set up I do it with the case on.
HeatingGeek yes.

It sounds like it could be a plate heat exchanger is blocked. Get someone out to have a look.
Shouldn't the gas pipe be bonded within 600mm or before the first tee??
Just watched the rest and you mentioned that...
@@mrman3509 I was just thinking "I thought I saw that and mentioned it" Glad you replied to it... I would of had to watch it again!!
Black top donkin regulator fault is the plastic pin that connects the diaphragm snapped I bet?
No idea. Its got replaced and it all works ok now.
My boiler faulty lights are on, CD28C. A is one and B is flashing, could not work out what the problem is. Can you kindly advise
I don't know off the top of my head. Check out your manual and get an engineer out ASAP
@@HeatingGeek Thank you. Engineer could not work it out either.....it is now a replacement job 😭
Nice easy job. Dongle regulators go wrong all the time!!!
