so my latest craigslist score was a couple of 80,000 btu natural gas heaters for the garage, the kind that you hang up in the garage. anyways i need to figure out how to get gas out to the garage as cheap as possible with out doing something thats not safe. my garage is attached, its only a single car but i have plans to make it 3-5 cars total when its done so having a heater this big is more of less planning for the future, not to mention i snagged them for 40 bucks each! so i was thinkint i could use that copper flexable pipe in 1/2" but i heard that stuff is really expensive now and i am not sure thats big enough. does anyone have any ideas? thanks :?
