Nat. Gas Heater Addition

Hi - I have updates on previous post of a year ago.
I'm still weighing my options on installing a NG heating unit.


Im in CT, my meter is a 250 at psi. I think 7in wc. Please see spec. sheet attached.

Questions are:
- What diameter will the new proposed line need to be?
- For this addition, will all the 1 need to be changed to 1-1/4?
- I believe my 250 meter should handle this no problem, just confirming.

I realize I could work on this with the charts, but instead of reinventing the wheel, I'd feel better listening to professionals who do this work everyday.

Again, thanks for your time.

You will have 270 k btu @100 ftwith longest length method..

what you have now only supports 195k btu..

Yes 1 1/4 will be needed.

Or have the reg at the meter upgraded to a 2 psi system and add regulators to all the appliances.. Ask gas company if they do this..

In NJ it was not common. Here in the south they will upgrade to 2 psi in a heart beat..

here is a red tag 2psi meter. ( pics below) I did two generator upgrades today to get enough gas to the gen set.

Notice the reg at the meter for the home side , a tapping for the gen, and reg at the gen.

Yours will be different as you need a reg at each appliance.

Unless if they up grade you can regulate the whole home just at the meter with one regulator, then run a separate line to your heater from the meter then regulate at the heater.

at 2psi you can run for example 3/8 trac pipe to the heater @ up to 400 feet and have 55k btu for the heater. Then regulate at the heater..

Hope this makes sense to you

Thanks Mike, I agree, real clean, great quality.

I talked to my service provider and they mentioned a few options as you did:
- a bump to 2psi, also needing regulators everywhere...cost makes this not a top choice.
- home run line to heater, but this is on the opposite side of the home...cost makes this not a top choice.

If I changed all of my 1" to 1-1/4", you said this would suffice.
Would I be running 1/2" or 3/4" to the heater?
Thanks again.

You would have to do the gas calculation

I cant do now...

If it were me I would increase the psi.. regulators are about 40 bucks...

Your cost 160 bucks..

Changing gas line size is a chore
