My electric water heater is in a corner of my home's garage in Dallas, TX. Code requires it to be raised 18" off the floor, so it creates this odd shaped nook in the corner. It currently sits on a framed out box that is built into the walls of the garage.
I'd like to buy a lowboy water heater (35" tall) and build a ~5' tall platform for it to set on to give the garage more unobstructed storage on the floor.
Is there a problem with this? I know the platform would have to support at least 600lbs, but would it violate any code? The T/P valve drains to the outside via a pipe and it still could. The supply and electrical come from the top, so they would essentially not have to move at all.
How close can the top of the heater be to the ceiling? I know I'll need room for the water connections but is there some "minimum ventilation" type distance?
This all seems like a good solution but I've never seen anything like it so I feel like I'm missing something.
