Low/ No Gas pressure...please help

[wheeto]

Yes is the short answer to your question but here's the long hand answer:

U6 meter - 6m[SUP]3[/SUP]/hr of gas

Here's the maths wheeto:

Heat input = (Gas Rate x Calorific Value of gas)/3.6

or

(6 x 38.6)/3.6 = 64.33 kW/hr

A U6/E6 meter will therefore supply appliances up to the value of 64kW max guaranteed! Any more than that required for the property and you'll require a larger gas meter!

Thanks for the maths, but you still got the unit wrong ... it's 64kW, not kW/h.

That's kind of sad that you'd question someone's GSR credentials on something so trivial! Hohummmmmm You're most likely right too wheeto but it detracts from the point I was getting accross to the op! Give yourself a pat on the back though for knowing your kW from your kW/hrs :clap:

Sorry. I'm sure you know I wasn't genuinely questioning your credentials - hence the emoticon in the first post - but everyone has pet peeves and one of mine is meaningless* units

Anyway you're right ... it's not helping the OP!

*OK, technically I suppose kW/hr is a unit of rate of change of power, struggling to find an application though.

It seems the OP has left the building!

We obviously weren't helpful enough or didn't tell them what they wanted to hear!

it sounds simple fault to me,if there getting 21 at the boiler but its dropping to zero when theres a a demand the governors shot

I'd say this too except the problem only occurs on the new boiler and not the existing one.

existing one could be standard efficiency new one band a zero governor,old one will work with a dodgy governor new one wont

does that take into account the diversity factor for meter sizing?

 

[AWheating]

i found it hard that some even posted suggesting what to test and look for without the OP showing any knowledge or competence. I know its hard to judge and we all give information out in good faith. You get shot down if you question people who in escence are strangers.
For all we know its somebody whos done the work themselves and is up tit creek now it does not work and nobody they have phoned will touch it. who knows?? you cant always believe what somebody has posted on the internet, if you read my online dating profile im 6ft5 and hung like a horse...... sadly only one of them is true

 

[Bernie2]

My view is that most people know about Gas Safe engineers being required. They also know that if they are not competent they should not touch it even if it is in their own home. If they do not know that, then what are Gas Safe doing to promote safety?

One has to assume they do know the law. So there would appear little harm in telling them how things work. At some point you have to trust people to behave in a proper manner. After all you can watch doctors at work on the telly some even show you in detail. But do you go out and and operate on people?

Nice analogy but imho not relevant as you wouldn't drop out your own appendix to save a few quid. I would like as you say to trust people but it is sometimes difficult.

I don't do gas, but would like to think if I did, and legally, I would know what to look for in the op situation without the cust having to trawl the internet to find a resolution. Even if i was stuck I would like to think I 'knew a man who could'. Something just seems off, but then that could just be the paranoia setting in, who said that

With so many crooks and so-called GSR people around, people (like myself) come on here to obtain the correct information so that we are not fobbed off and are better informed.

If you're not happy giving advice in an open forum to the public then stick to the exclusive GSR forums.

 

[AWheating]

unfortunately although people know the law and right and wrong it will not stop them for what ever reason doing as they please. As a profession we should atleast try our best to avoid giving irresponsible advise. You cant control what people do with any information you give them, but you can try your best to avoid giving information when there is doubt about the legitimacy of the person or questions.

I cant see why some posters get upset when they get questioned about the reason's behind the posts, if they want an honest, safe and informative answer then why be defensive? some members even get upset and LIKE any post that seems to even question another member just because they dont like what was said in one post ( you can see patterns from some members and its petty)

ask yourself this. If the original post said ive fitted my own boiler and it wont work, please tell me how to fix it myself? what would your answer have been? i suppose atleast id like them more for the honesty.

why do people need to ask detailed gas related questions if they are not either GSR or learning/training to be?? why do you need to be better informed about these things unless it relates to your job or future job??

if you cant see the argument that caution is needed when giving advise about such things and its not unreasonable to question some people then im lost

 

[M.Joshi]

I agree caution is needed but people come on here to be better informed because they have been stung/fobbed off in the past and also some of the tosh that some GSR people say when you speak to them to obtain quotes for repairs etc. - I don't mean that about most forum members on here who seem to know their trade well.

It's good to be better informed so that you know that the plumber/GSR person doing the work for you isn't fobbing you off.

I may ask technical questions but that doesn't mean that I will carry out gas work myself! I am just interested to find out the correct answer/solution.

Iunderstand what your saying and agree that its probably a good thing to be well informed. You have to draw a line tho, giving technical answers or advise on how to test for things is not needed for a customer to be well informed. There has to be a line drawn in the sand between customer and engineer (trainee incl) when you give answers imo. If you have a customer having to go onto a internet forum to ask questions for her/his engineer the only real answer is to get a better engineer. If you was a customer and your engineer asked you to try and find answers you should be worried.

i cant say i have never given answers to poeple i wished i didnt, but im slowly learning its advisable not to if im unsure. Some posts are blantently a diyer wanting to work illegally. Some you just dont know and take a judgement, we are human afterall.

Im perfectly fine with tradepeople who want to learn and advance there knowledge asking questions, i myself wanted to understand electrics so went to college for 4.5 years to learn it. During that time i probably peed off pleanty of sparks asking question after question .

Reading posts and listening to customers it opens your eyes to how poorly the trade is viewed in many peoples eyes, the only gas engineers you see on tv are one ripping off customers because it sells and brings in viewers. Many customers expect to be stung as you put it, so as engineers i guess we all have some part to play in trying to lift the opinions of the trade. So even tho this is just an open forum maybe we ow it to ourseves to answer questions professionally. What exactly is the best way to do this is up for debate. You get accused of being a rip of merchant when you disconnect a dangerous appliance, or a wazock for suggesting somebody gets a competent person in..... sometimes you cant win,

i need a beer.

 

[AWheating]

this is one reason why i question giving answers in open forums, this is what many customers are thinking before they phone you up about work. Am i answering a question to an ilegall fitter? if so am i only helping make the above statement more true. but on the flip side the more we discuss technical issues and the more we all learn and become better engineers the better. Its a hard balance i must admit.

 

[Bernie2]

The problem is the questioner could find all the answers out, simply by buying a book, looking at MI's or going down to their main library and reading the relevant BS document for free. I like to think the person who I am doing the work for knows as much about the job as me. Then you get mutual understanding of what is involved. It is not necessarily that they will go away and work illegally. It is like speeding, it is entirely up to the driver if they decide to do so, but I would not stop a person from learning to drive just because they might speed. Its the same with a gun, having the knowledge or giving the knowledge about how to fire one is perhaps harmless, it is only when a nutter decides to kill that they become dangerous.


I can appreciate the point your making and to a certain degree I agree with you, but what if the person knows little about what they are doing but still decides to do it? Surely that is far more dangerous? As a young man I thought flying a glider looks easy, but when you learn what is really involved its a whole new game and you realise it isn't.

I don't suppose this thread would have originated had the OP employed an engineer off of the Gas Safe website.

It would be great if everyone on the GSR website are as knowledgeable as most people on this forum but the sad fact is, they arent.

We shouldn't speculate on who the OP has employed to carry out the work.

Hopefully the OP will come back and answer all the questions above being raised about the installer!

 

[Rickster123]

What makes me laugh are the people giving out boiler advice without being qualified to do so! It really is a case of the blind leading the blind and I'm certain that in the not to distant future it will lead to trouble.

Who's speculating?
If even a novice GSR found themselves in this predicament all they would have to do is call in a Gas Safe Inspector who would visit the site and give them top quality advice free of charge.
What kind of 'engineer' gets their customer to post a question like this on an Internet forum?
Possibly one who's sole source of knowledge has been by posting questions on various forums.
