Videos like this are invaluable for clueless people. This teaches far more than college. Very interesting! Certainly taught me! Thankyou!

[@abandofbrotherslondon6410]

Thanks great video! I feel as if I’m a good engineer, but with watching your videos, It’s making me even better 👍🏾

[@stewartharrod1706]

This is the best explanation of boiler sequence of operation there is fact

[@jamalamin2394]

Finally, been dying to see this thanks for this Derek 👌🏽

[@eofmadar4481]

Top man, well explained thanks.

[@yasreh5845]

Thank you i always learn something from your videos 👍✌

[@mohammednadeem7274]

Another great video Derek, its really great for fault finding, excellent. 👍👍😀😀

[@richardhodgson7443]

Brilliant explanation Derek, thanks 🙏

[@sanjk9116]

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

[@tomkatgastraining]

Thanks for watching and well done, welcome to the world of gas 👍🏻

[@zahurzaman4865]

Another nice video for new entrants into the gas industry

[@pookievision]

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! :)

Check this link out it has the ACS revision videos 👍🏻

[@andrewmillwardwatford9410]

Love your videos.

[@hdhanji8006]

Both great engineers, any gas Safe folks out there looking to be the best must watch Derek and Andrew's videos ;)

@@hdhanji8006 Thank you

[@obaidullahibrahimi883]

Thanks again

Derek u legend

[@mj0n4id36]

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.

[@tomkatgastraining]

Yep the APS is a fan providing switch

[@conand1413]

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

[@AnEyeScream]

Thank you, Nikola Ditsov

[@josepeixoto3384]

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.

[@piotrserafin9728]

Can you please do a video on setting Burner pressure on Turbomax, love your videos, really keep the standards up.

[@tomkatgastraining]

Good idea 👍🏻

[@groovejet33]

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

What does fan do? And for sequence of operations why pump come on seconds After room tsta

[@suheilhanna873]

First one to watch 😊👍

[@mustafaahmed842]

Can you do the same video but for high efficiency boilers with premix burners. Part 1 and 2

[@tomkatgastraining]

On the list to do 👍🏻

[@mustafaahmed842]

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

[@suheilhanna873]

💫💫💫💫💫

[@iulian9200]

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 )

[@craighurst3599]

CH👍

[@joetodd7944]

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