gas line and pressure question for garage

[oiler]

I've done a search and really came up with nothing for my problem
I've got a detached garage 240 feet from my meter on my house
I'm installing a 75K radiant heater
going by gas pipe charts I can use 1 inch PE for the supply line so I'm going to order a prebuilt one with fused stainless risors
My question is about available pressure from the house
Can you run into supply issues with this distance from the house?
I got the same heater in my attached garage and am also using gas for house heat,fireplace,hot water tank and bbq.
Just wondering if you can have too many applliances and how to determine that.
we have a gas coop here and they can't answer it and I've yet to get a gasfitter to call me back.
Thanks for any info
Jeff

You concern should be focused on volume, not pressure. The typical gas pressure on your side is less than 3PSI, while it is delivered to your home at around 60PSI, so the regulator will maintain the pressure and has plenty of reserve to rely on. No issue with pressure.

Now - on to volume. What is the smallest size pipe that will be between your new heater and the meter - ahead of your tie in included? How long is this new run going to be?

the run will be about 240 feet risor to risor
also will likely have 30 feet of black pipe inside the shop
the heater has a 1/2 pipe inlet
the pipe going into the metre and into my hose is 3/4
thanks

Typical gas pressure delivered to your house is measured in inches of water column and the pressure to the regulator is more apt to be less than 5 Psig.

You may have a problem with both pressure and volume..........most of those household pressure regulators are equipped with a 1/4" orifice.

Would consult with your gas utility, gas fitters I dealt with didn't have a good handle on that capacity stuff and generally just installed what was called for.
Just my experience anyway.................

They may ask that the supply be tee'd off ahead of the regulator and a new line run with a separate regulator.
