Hi Derek. I passed my ACS just now and the last thing i did before going in was watch this series, the flue gas analysis videos and the safety control videos. My tutors at options skills have been exceptional (Brian and Mikey) but i have used your teachings throughout training portfolio and ACS so thank you for your time snd effort
Recently became a service/repair engineer. Really appreciated this video. Company put me on service only as have zero experience get used to the boiler sequence of operation and also the system itself operation. Got 6 months study up for repairs ect so these videos will really help! Do you have one for system sequence! Appreciate yas! :)
This short video is amazing! Gives me a much better understanding on the sequence of operation. Will definitely watch this one again at some point. Glad you have done this video (I love all your videos). You said the air pressure switch is to check if the fan is running. Is this the only purpose for it? Much appreciated Derek 👍🏻 Asian Jon. Training.
Thank you,sir; I have a question, please: Roca Victoria 20/20, if the flow sensor,the Hall +magnet sensor, it is only in the domestic hot water,circuit, faucets,if it is bad (or disconnected?) the CH,central heating, will still work perfectly, won't it? thanks; and again, a masters explanation was provided there.
So just to be sure I understand. Only once the fan starts running, then the air pressure switch, creates a switch so the normally open circuit closes and this proves the fan is running so the boiler can then Carry on and open the gas valve ect?
Thanks for video Any chance for a video about gas fires: insert, DFe and how to differentiate between when on job. Alot of videos about ventilation but not many clear about how to easily and clearly tell which cat this or that gas fire fall under . Would appreciate that alot
Brilliant. These videos are literally cutting down the time it takes on a job. Understanding what to expect from the boiler of a particular fault makes fault finding simple
I don't understand why it needs pomp proving switch in hot water mode. It had first the flow switch that is proving the presence of water in system and also means it's enough pressure (by spinning speed )
Videos like this are invaluable for clueless people. This teaches far more than college. Very interesting! Certainly taught me! Thankyou!
This is the best explanation of boiler sequence of operation there is fact
Thanks great video! I feel as if I’m a good engineer, but with watching your videos, It’s making me even better 👍🏾
Finally, been dying to see this thanks for this Derek 👌🏽
Another great video Derek, its really great for fault finding, excellent. 👍👍😀😀

Thanks for watching and well done, welcome to the world of gas 👍🏻
Another nice video for new entrants into the gas industry
Brilliant explanation Derek, thanks 🙏
Thanks Derek brilliant explanation....
Great informative video tanx for the upload👍
Excellent video, thank you Derek👍👍👍

Taking my gas next month, you have been recommended. This is gold! Just need to figure out which vids are most useful? Nice one tomkat

Asian Jon. Training.
Yep the APS is a fan providing switch

Top man, well explained thanks.
Thank you, Nikola Ditsov
Easly explained nice one
Very informative, thanks!!
Thanks for the vid Derek 😁 just watched Aaron trainee 👌👍
Can you please do a video on setting Burner pressure on Turbomax, love your videos, really keep the standards up.
Good idea 👍🏻
So so helpful. Thanks BiG D
Thanks again
Thanks for video

Derek u legend
What does fan do? And for sequence of operations why pump come on seconds After room tsta
First one to watch 😊👍
Love your videos.
Both great engineers, any gas Safe folks out there looking to be the best must watch Derek and Andrew's videos ;)
@@hdhanji8006 Thank you
Can you do the same video but for high efficiency boilers with premix burners. Part 1 and 2
On the list to do 👍🏻

Good video. Bread & butter stuff but still ....I liked the content etc
👍👍👍

Something else I have learned when I get no hot water on my vaillant boiler it's usually the water sensor not working f75
