Larger Capacity Gas Meter?

[sturharv]

Just some help please on what size gas meter is required.

The project is having various kitchen appliances equating to 135kW (there is some large 50kW oven and other baking appliances in there!)
Also there is a 50kW condensing boiler to heat the building. I understand that it is unlikely all the appliances will be running at the same time, but I assume the gas meter and supply pipe will have to be sized for that situation.

Therefore there will be a maximum load of 185kW.

What size gas meter would generally be sized for this. A standard domestic meter is the U6, what is the U16 capable of doing? or will it need to be larger than this?

I need to try and calculate the annual kWh's, has anyone got a 'rule of thumb' calculation for this?

A U16 should be fine.

But then again perhaps it won't be.

U25 mate.

Most appliances will state what gas they will use at maximum in m3/hr.

Add all these figures up then see what meter will comfortably handle this

A U6 = 6 cubic metres an hour will supply 60kW, or a bit over, but the "droop" in the meter can be significant.
So a U16 could cover it, but they'll only fit one for you for a mere few hundred quid if their supply to it is adequate, If not, they increase the size of their supply - at your expense, which is a lot.


OOps, I saw the 135, not the 185!

Cough, Cough.

185 Kw = 17.29m³h

An U 16 is 16 m³h close but not quite close enough.

You was warned. now wheres that aris cream

Allowing for diversity factors a U16 might cut the mustard.

Steady now Lee, steady, (snigger emoticon)

My fault didn't read the 185kw bit, just saw the 135kw.

Brain didnt register the rest. Seen similar though on u16 and seem ok, doesn't make it right though.

Diversity in a Commercial kitchen

Good practice would allow at least 10-15% higher than the calculated load.

 

[clf-gas]

For sure you get diversity in a com kitchen, I meet all nationalities on a daily basis DIA.

Oh and U25 is the way. on a domestic job now where we have had to upgrade to a U16, two boilers, large range cooker and two fires , Anyone got a meter tail for 15mm .

Just some help please on what size gas meter is required.

Stuart, we know from your past postings ( which have not always been very polite to us who give you advice ) that you are apparently employed to design gas and heating systems.

Its very galling to a professional that you are able to do that work without having any qualifications or practical experience just because you dont touch actual gas fittings yourself.

Yet again my advice would be that you need to take sufficient training to be able to do your work without having to ask such basic advice on a free forum.

Alternatively employ a proper consultant to assist you.

Can I suggest that qualified people on this forum DONT give him this valuable free advice that he should really know himself or might at least pay for within the project costings.

Ahh Tony, thought you may crawl out of your hole at some point!!

Again you seem better at slating the actual post rather than putting together a constructive or helpful answer to the actual question. I am not responsible for sizing the gas meters or other items which requires specialist knowledge (although for some reason you seem to know what exactly I do), I am simply curious as how these things work so I can understand what needs to be done i.e. costs for the work etc. so get off your high horse.

Tony, we know from your past 'postings' www.diynot.com/forums/viewtopic.php?p=816166#816166 that I am not the only one that you tend to annoy with your comments.

Keeping installing them combi’s Tony!!!!!
