Understanding gas pressure with gas boilers.
Started going to work with my dad when I was nine ish, and was paid with frothy coffee.
I'm now 58 and still watch your training videos.
Every day's a school day
Thank You
Thanks, Roy and Allen. Has helped order things in my brain after 4 weeks on a training course!
Thanks very much for your comment, please consider subscribing to support the channel 🙂
I am about to do my domestic gas principals exam. The videos are superb and make it very clear to understand once I have read it in the book 👍
Excellent Roy. Excellent.
Thank you both for your great videos.
Thanks Allen and Roy. Keep up the good work. One of the best gas channels on CZcams.
Thanks for always putting on videos Guys.
Would be good to have a video on what you do if the burner pressure is to high or to low.
Gas rates to low or to high? And what investigating you need to do
What you need to do if inlets to small and what you need to leave at as.
Thanks for content and your input Alan and Roy. I'm always picking up little points every video.
Thanks
We have done videos on burners pressures, Please check out the full list on Viva Training Academy list. Thanks.
I'm interested in Unvented cinders. You put out a great video on that subject not so long ago. I'm not sure if I'd give a career a go in gas / heating and plumbering if I was 20yrs younger. But there are a few very talented tradesmen on here. I do really appreciate you all passing on the info and tips and tricks. Plumbering is a skill and the best make it look so easy, but it's far from it!
I've just passed level 2 plumbing and heating and i so far can't find a plumbers mate job for love or money i retained at 55 😭😭😭
Plumbing and heating are separate disciplines with different qualifications. There is a grey area between them.
I would not send a domestic plumber to a forced air commercial system.
Thank you both. 👍
Thanks for uploading this info, I'm only a DIYer and don't touch gas. But seeing how things work and how things should be is very interesting.
Thanks for watching!
U explain so nicely....u people are good people who help apprentice like me
thank you Roy was very helpful
Very nice information
Thanks again
Hi Allen, Roy,
Another good video - however, reading some of the comments being made, it maybe a good idea to explain in more detail the 'what for's' that go into why we (or should) check the 'Standing Pressure' of an installation correctly - as clearly there are trainee students following your training videos for obvious reasons, and whilst reading some of the comments, there appears to be some misinformation in what checking Standing Pressure correctly is actually showing to the Gas Engineer, and what concerns he / she should be having if a certain parameters were in question.
Please explain what more you think we should include? Thanks.
@@AllenHart999 Reference the Standing pressure proves that gas is present in the pipework and nothing else comment. This is not technically correct if we are openly wishing to help trainees understand these tests and what they can show fully.
We can also identify from this test if the regulator is operating as it is designed to do - and thus closing off rather than simply allowing full pressure through to the applainces via a failed regulator. If a concern is found, this then can lead onto actions to be followed if such a thing arrose.
Forgot to mention that burner pressure hose needs to be on the test point before the appliance fires up, if you loosen it while it’s on a jet of flame will shoot out of it
Still find a lot of experienced gas engineers that get standing and working pressures mixed up. Standing pressure proves that gas is present in the pipework and nothing else. I've had heated debates with installers that say that boiler is fine because it's got 23mb standing pressure, I've 'at risked' it because that standing pressure dips to 11mb working pressure when the boiler fires up 🤦
Been there my friend!
Standing pressure isnt just to prove theres gas its to show that there is gas and there isnt a leak
Don't forget dynamic pressure
Hi
So inlet pressure and working pressure at the appliance is the same? And should be no more than 1 mil bar dropped then meter working pressure,
Any body confirm it ?
Can you leave the u gauge unattended when you go inside to fire boiler up
What the difference between operative and working pressure?
Operating and Working pressure is the same thing. Dunno why they announce it as something different.
2mbar Roy not 0.2mbar
What happens if more than one appliance is running at the same time. Could the inlet working pressure not drop even further on that boiler causing it to fail?
Yes. I have a commercial site, there’s 160m of 100mm iron pipework, there isn’t enough gas pressure to run both the new boilers at the same time.
Ideal boiler they allow 14mb, does it mean we allowed to pass it please????
No
They don’t allow it at all. They say they will work down to that, totally different question. We are allowed 1 mb drop over the installation for pipe sizing.
What if gas rate is too high?
I called out a gas supplier a few years back when I found 30mbr standing pressure in a house in the next street to me. I waited a bit then had to shoot off, so arranged to call back. When I came back, the supplier had been and told the customer there was no such thing as standing pressure, but he’d changed the regulator anyway ??? It made me feel a bit foolish in front of the house owner to be honest, as I’m sure they probably thought I was full of sh1t compared to the national company, but I explained the pressure was now 20mbr, so whether he had heard or not it was now correct.................
I also called them out over 20 years now, similar story. There’s no requirement to test standing pressure and I still wonder why it’s even discussed to be honest. It’s a a waste of time and effort.
There is standing pressure and he is a jerk or just an idiot. For low pressure installations 23 - 26mbar and for medium pressure its 23 to 30mbar. If it is higher it makes the regulator to lock out to remove danger to any person in the property. Ta-daaa.!
Can you have gas pressure....but without the container?
No, and that's why the earth is flat and stationary.
@@7magicful A man of science. Like it.
Too much irrelevant talks and little work too much noise and bad method of teaching
Sound quality poor!
How can we do a hobb tightness test to check fsd
