GAS SAFETY CONTROLS part 4 looking at zero gas valves, thermistors, and gas meter controls. 

Wish i had u 15yrs ago doing me gas😂😂great video Derek keep it up 👍

Thank to Derek i have learn everything about gas.Saying Thank you to Darek is not enough .Take care and wish you good health

thank you Derek so informative, clear and helpful as always

Very much valuable information. I really appreciate. Thank you

5 stars explanation on those 4 videos , thanks 👍

Hello Derek. I passed my acs today can't thank you enough for all your videos and info you share. Your videos work magic and you make people's dreams come true mate👍👍keep the good work all the best and I hope to meet you one day as I'm based in Denton, Manchester. Bless you Sir!!!

Great video Derek as always. Nearly due for my ACS exam , i have learnt a lot from your videos. Thank you

Much appreciated Derek ...cheers fella.

Again , again and again thank you sooo much Derek Very helpful videos , you are the best

Watched all of the control videos and they have been very useful. Got my first ACS soon and these have been by far a better explanation than any training I've received. The use of the deconstructed appliances is brilliant. If only my practical training had been this good. Thanks Derek 👍

Just been back to college this week and these videos have really helped everything clicking into place now. Thanks Derek

Finally I understand the gas valve in my baxi boiler and now have a search term to get some more info about it. Thanks

Fantastic video. Thanks Derek for your effort👍😀

Top stuff. I’m going to go look up zero governors and get some diagrams now. Look forward to your videos in tightness testing.

Another excellent video. Love your videos. Cheers Derek

Another great video. Keep it up Derek

We do appreciate your hard work thanks million mate

Very good video once again. 😀

Thanks for videos,well explained.

Good stuff once again.

Excellent video derek, well explained like always great job. 👌👌👌

Love these training videos. I've been out of the trade a few years and will be sitting my ACS in a few months so it's brilliant for refreshing the brain cells and also learning new things as well. I much appreciate the effort and time you have put in to making these videos. Cheers guys !

Appreciate your videos a lot mate, you’re a great teacher. I’m doing the ACS in the next few months and your videos are making it so much easier for me to understand how everything works. Thanks for all your hard work mate! 👍🏼👍🏼

Top Class video ☝️

Hello Derek, great videos am absorbing so much knowledge from all of your videos so far, would you be able to do a video of a cross-section of a zero guvenor and meter governor to show us how exactly they work inside? keep up the great work!!

Absolutely amazing. Start to end. So many controls so much to learn. I won’t worry though as I have access to your videos. Question time 😬 Can we put just a lock on the ECV if we wanted or does that have to be cadent too? (Sorry in advance if this next question is stupid) Why is the regulator income pressure on a low pressure 75mb / 2bar when the regulator has to then regulate it down to 19-28mb? Just learnt after watching this video that working pressure at the meter, if it’s not 21 plus/minus 2 the regulator is wrong. Not the pipe sizing. However, if the working pressure at the appliance is more than 1mb difference then that at the meter, that’s when it’s related to incorrect pipe sizing. Now I know a bit more about zero governors! Thanks for showing us a medium pressure regulator and how it can be identified (with the upso valve) Don’t think I’ve heard or come across a thermistor before. Dry pocket and wet pocket. Wow! Thanks Derek 👍🏻 Asian Jon. Training

Hello Derek. Thanks you for your video and passing your knowledge 💪💪 Got a question 🙋‍♂️ Don’t know if am just being stupid Doing let-by on a zero governor gas valve I find that the gas pressure goes up when I isolate it from the boiler. Using p1. Or how to properly check if the gas valve is letting by as sometime the spring might not sit all the way

Great little series on gas controls. It would be good to see a video on a meduim operating pressure meter showing the let by and regulator let by tests (no offence intended to a certain female gas trainer on RU-vid) 😜

hey there will thermistors and high limitor work on the same principle as a thermostat and use the bi-metal to break the electricity circuit ? thanks

Could you make a video on tightness testing on a medium pressure meters it really confuses me cheers derek top bloke

👌👌👍👍

👍👍👍

👍👍

Watched 👍 Aaron trainee 😁

Lovely thank w😢

👍🏾

hello Derek if I have meters cant i adjust reg pressure if needed?

Great video again. What is next weeks video about?

👍
