Why cannot a regular house hot water heater be installed into a mobile home by professionals? Why does everyone want to only put in a mobile home water heater? Seems as if a water heater and pipes are a water heater and pipes.
 
I await experts, but off the top guesses:
1. Easily convertible from NG to Propane for gas models, and rated/listing/evaluation to HUD specifications.
2. side inlets vs. standard top inlets
 
Most mobile homes have a closet off the garage that needs a shorter tank. Are you talking electric, natural gas or propane?
 
Pretty touchy subject. Around here if it doesn't have that mobile home approved sticker on it your not going to pass
code. There a lot more expensive too. So its not just the plumber wanting to put one in. I believe if you had a fire and
a regular water heater caused it you could have problems with you insurance company.
 
I've been in a mobile home since the eighties and have had three "normal" electric water heaters so far. The last I bought last November was a shorter size Rheem for convenience.

Exactly. My second one installed was a 40 gallon 220v electric shorty. Nothing special, but I added a drain pan and drain to collect leaks if they were to occur.
 
From what I remember the main issue is with installing a gas water heater into one of those mobile home closets without any combustion air. Mobile homes have their own code.

So the gas models had make up air supplied through a dual vent.

The electrics were side connect so they needed a vacuum relief

but I might be going nuts and dreamed all that. I don’t work in mobile homes unless I’m tricked into it some how.
 
The door in my w/h closet has about 1' square vent in it to allow heat to escape the closet.

If it’s gas, that’s for combustion air. Gas needs air to burn. I believe the codes do not want the combustion air to come from the living space in a mobile home.

I could be wrong though, I don’t keep up with the codes.
