Looking at running a natural gas line from one side of my house to the other to supply a pool heater.
To run it outside and underground is impossible. Too many things in the way.
Can it be run thru the basement along the unfinished ceiling?
If not, can it be run outside mounted on the wall of the house?
Thanks

Either would be ok providing code was followed.
You’ll likely have to pull permits from your local jurisdiction.

Have you checked to see if your gas supply can handle it?
Pool heaters use quite a bit of fuel if the pool is fairly large.
