I have a single wide trailer. (The main gas line blew out the back and is under code so $4,000.00 to fix it plus permits because the main need to be moved from under the Trailer).
I would like to put in an on-demand water heater that uses propane from a tank. Usage would be for 2 people, 2 showers a day and washing dishes
Can I use the small propane tanks like for a barbecue? I have one old tank about 2 times the size of the usual barbecue tank — I think 40lbs. I think barbecue tanks are 20 LB. I am a little rusty at home repairs but I have to do this one myself due to my funds being low. I am in Phoenix, Arizona so no worries about freezing lines. Can I run the flue through the roof where the old water heater ran through, or does it need to be made larger than 4"?
