Hello All I know I have watched TOH forever and I have never seen anything on Manufactured Homes but at this time I own one in Arizona. Recently my hot water heater went out and I went to purchases a new one. After talking to anther diy they told me make sure it is approved for a Manufactured Home. So I set out on a quest to locate one boy you want to talk about a shock try $250 more than the others (propane) for a regular house. When I started questioning why no one could tell me does anyone know the difference? Also after talking to a plumber that if I did not install an approved hot water fro a manufactured home if I had an insurance claim that the insurance company cold nullify my home owners insurance claim does anyone know about this. Any information would be helpful. I did install a hot water heater that was approved for a manufactured home. Oh yea I also discovered the hot water heater I pulled out someone did not convert it from natural gas to propane it was all soot up. The floor under the hot water heater was scorched through the linoleum boy I'm so lucky it did not burn the house down.
