I currently have a 200 CFH natural gas meter. I have added a generator
that uses 245 CFH at full load.
I finally got a response from my gas company today (after MANY messages
left). They said the good news is that the line from the street is
sufficient, and would not need to be replaced. However, the meter and
regulator needed to be changed. The cost? $1043!!
I argued and said this was ridiculous. I shouldn't have to pay over
$1000 to buy more gas from you. Of course, they don't care about that
(I guess they don't see the "big picture"). I can't get in touch with
anyone other than a call taker at the company. It's Centerpoint
Has anyone else had a similar experience? I have no question that they
are upgrading to much more than I would need. But they stand firm that
that's what they "calculated" and if they budge then the could be
liable from a safety standpoint... BS.
I would guess that their regulations require them to provide X amount of
capacity, an amount that should accommodate most residential customers.
Your needs may be considered commercial and if so the regulations may
require both a different type of meter and likely allow them to charge more.
They do see the big picture. You want gas. They have gas. You need a
larger meter. They will charge you for it and make money from it. You get
pissed off. They still have the gas to sell to others. You still want gas
so you pay to have the meter installed.
How often will the generator run? Figure your annual consumption and how
much profit they can make from you. How long do they have to supply you to
make back the $1043? If it is a generator for power failures only, it
won't be in this century.
You should check these thing out before you buy a piece of equipment.
Sorry, but I don't see where they have any obligation to do this for you. I
think you will find the propane costs equally shocking.
FWIW, yes, I've done gas upgrades a few times at work. Nothing is free.
Fair enough. I realize it will cost something, I guess $1043 just
seems expensive. I can't imagine that their cost for a meter is
anywhere near that. I see that new, lower capacity meters cost just
more than $100. Maybe the bigger ones are significantly more complex.
After not having a response from them for over a month prior to today,
I have come to realize that I will have to use what I currently have.
It works fine. I'll just not be able to run the furnace, fireplaces,
and central AC all at once :-)
In their infinite wisdom they calculated that I need a 690CFH meter. I
feel that 400 would be more than adequate. I currently have a 200CFH
meter and am adding 245CFH. The meter I currently have was also sized
by them. That math does not add up to me. Someone else suggested that
I don't run at full capacity. I don't. I won't go over 60% at the
most. Only needed a generator this big so I could run my 5 ton central
Thanks for the responses. Just a bad case of sticker shock!
Huh, and they won't install a new meter and line dedicated to the new
equipment? THat would eb the easiest way.
Ah, in that case yes, you should be fine.
I was toying with the idea that you could get a compressor and store up
the gas against need downstream from the meter. Unfortunately, the lowest
cost CNG compressor I could find was two grand. The only other option
otehr than living with the current limits would be to go to tanks of
propane. Of copurse if you were making that switch, you might as well
make the switch to all of your gas needs...
Sheesh, that's a big genset. How much did that cost?
Remove the dead poet to e-mail, tho CC\'d posts are unwelcome.
Mean People Suck - It takes two deviations to get cool.
Actually, Generac came out with a new air cooled generator this year
that they say is "Certified for 5 Ton Central AC". It a 16kwLP and
15kwNG. I was a bit suspicious, so I installed a Kickstart start
capacitor and relay (supposed to help with compressor starting in low
voltage situations, reduce startup current (or at least lower the
duration unit is pulling LRA)). http://www.kickstartoem.com
The generator does indeed start the unit. They claim it will start a 5
ton with a 7kw (if my memory is correct) auxillary load. I have only
started it with about 3kw additional load. It's a Generac 5244
(aluminum enclosure). The steel enclosure is a model 5243, I believe.
It costs about $3500 or so with a 16 circuit, 100amp transfer switch.
Not too bad of a price, I don't think.
I spent 16 days without power last year when Hurricane Rita hit.
Hopefully I won't be without AC again in the event of another hit.
They are replacing the meter, regulator, and labor. Check out some pricing
here for a smaller meter.
http://www.plumbingsupply.com/gas.html They don't list the 400 or larger
I just rebuilt a regulator and found that a new one of the capacity we need
it $800. I'm sure yours will be less.

I think there is a good chance you can run your generator wide open.
When you add the tolerances, you probably won't even notice the
Give it a try first, before you get all upset about nothing.
And if there is a restriction, it is more than likely in that cheesy
line you have running from the meter rather than the meter.
Haha. That would be a good guess typically. I have run a 1 1/4 yellow
poly natural gas line from the meter, though. More than good enough!
I was going to ask about the meter itself. You imply that I can
probably get more than the 200 CFH for which it's rated. I have seen
information that seems to indicate that the 200CFH it rated for is
relating more to the fact that it can accurately measure the flow up to
200CFH, rather than indicating that's the most that will actually flow
through the meter.
As I stated previously, I don't think I need much more than the 200CFH.
I have run at full load. No problems. So that says I can get more
than 200, presumably (if the 245CFH consumption is correct). I just
like to do things to spec most of the time. I start wondering, ok,
what if I'm drying clothes, both water heaters come on, etc. A surging
generator that is running a central AC is not a good thing (trust me, I
know). Luckily it was only a burned up contactor. Maybe I'm
over-analyzing this, but I'd rather do it now than when the power is
My gas company doesn't make any money on the gas they sell me. Only the
delivery of the gas. If you do the same, they could care less how much gas
they deliver to you. So they make money on delivering the gas to your
house. Also, as someone else said, if they do make money on the gas the
amount that you will use for power outages is minimal.
A good friend uses compressed natural gas to run his vehicles. He
compresses his home gas to 1500 pounds but runs the compressor slow so
as to not draw too much thru the meter.
gas meters can supply way more than there rated volume, if you draw too
much it will damager the rubber bladder inside but not cause a gas leak
or hazard, the worst is the metter quits working..
this all from my buddy a engineer. he designed cast and machined the
entire system himself.
