Piping For Propane Shower Heater

[thairhone]

I need to find out the best way to get propane up to a second story, MBR bathroom to feed a gas shower heater. I plan to use propane in both indoor and outdoor kitchen areas and would like to run it for our shower upstairs. Has anyone done this or have any suggestions? Black steel pipe, plastic tubing, or what???? I know electric would be easier, but.....Thanks. T

copperpipe with pvc insulation (to protect copper). max one meter LPG hose in each end. LPG hose, the expensive orange one with manufactor date on it, to be replaced within 10 years

actually I would rather keep the LPG burners/heaters in one vented fireproof location, and install hotwaterpipes to the taps. safer and less expensive
