Low/ No Gas pressure...please help

[diamondgas]

this should be common sense to any gas engineer. This engineer is either an idiot or not a gas engineer??

:iagree: first school basics you'd hope :iagree:

 

[Resolute]

Good luck and let us know how it goes.

hi all

i can't thank you all enough for the info you have provided so far. Its a lil late now so i cant contact him to get any more info but will hopefully get onto it tomorrow to have him answer/ consider the points mentioned.

i'll sleep a bit better tonight knowing i've had second opinion from some great guys!!!

thanks again

we are here to help 🙂

honestly tho, if your engineer needs his customer to ask simple questions on the internet i would be worried about the work thats been done and everything aside consider a second engineer.

It'd be nice to know the outcome of your issue Sara should you be willing to return to the lions den 🙂 Were ***** cats really 🙂 Good night :waving:

cant see why he is getting zero my first thought was he was using the wrong test point on a zero govenor but he wouldnt get 21mb standing on that

Yes it is a bit peculiar. I am not saying the problem is air although air will compress to give a pressure reading, but it will not ignite. Seemingly the pipe is connected close to the meter and runs directly to the boiler wihtout any branches off. I assume its at least 22mm without to many bends or restricitions so it should work. Unless of course its blocked. I find more information would be needed to give a closer guess. The idea of continually firing the boiler up is about all a none gas person can do without breaking the gas train to check air has been purged. It doesn't however explain why the pressure drops to zero, although a fast acting gas valve can do that. Its hard to find out there are so many ifs and buts.

A U6 meter will supply about 64kW/hr ... Your guy if he's GSR will know all this.

64kW/hr? What sort of unit is that? Are you sure you're GSR? 😛

Gas Meters - Information if any doubt 😉 Second row.

Hi did you get the problem fixed ?

 

[diamondgas]

64kW/hr? What sort of unit is that? Are you sure you're GSR? 😛

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 😉
