Gas company line pressure needed?

[JamesFromAustin]

Hi All,

I'm in a bind. Building a 2nd structure in my back yard. This structure is 100 ft away from main house. The new structure has high natural gas needs. My total BTU's went from 200K to 1.3M BTU's due to new structure. I've been told I need to submit higher pressure request to nat gas supplier, which I did. But they won't calculate how much pressure I need.

Is there a basic formula or online calculator that can be used to do this? And once this is all said and done, are their whole house regulators that will allow me to drop the pressure to the normal ~7 w.c. pressure so that I don't have do to do this at each appliance?

Thank you.

UPC has all the charts in appendix.
Pressure regulators can be sized to do what you need. We go to the regulator distributor, they engineer the regulator and order or fit up from their stock.
sounds like you need PV solar and heat pumps if you need that many BTUs

I think 2 PSI is the next pressure up size. I expect you want 2 PSI. I am not a pro.

Next step is to find what size pipe you will need. Try https://www.google.com/search?q="2+psi+natural+gas"+calculator for calculators. I would aim for 1 psi drop or less to give the regulator enough to work with.
