Plumbing Propane tank to 2 Eccotemp 45HI-LP Propane Heaters

[Pascal Poulin]

Hey guys, I would like to plumb propane to these two HWODs for a shower trailer I am building. Wondering what supplies I would need to do that, regulator, pipes ect. I would have a 100lbs propane tank outside. Would I have to use copper pipes and weld? Could I use individual lines to each HWOD, that are flexible so that I dont need to hire plumber. In a bit of a hurry so hiring a plumber may not be an option

Thanks a lot for the help in advance

Gallon of lp = 91000 btu's 100lb tank holds 19.2 gallons every thing could be piped in flared fittings, soft copper tubing. Might want to think about a rented lp tank just depends how many people are taking showers. Tanks only hold 80% of volume.
