Default Re: elevating hot water heaters.

As David alluded to, the requirement is for elevation of the ignition source. That does not equate to the water heater needing to be elevated 18 inches above the floor.

I have an electric water heater in my garage. The lowest potential source of ignition is 10 inches above the bottom of the unit. The unit itself only needs to be elevated 8 inches to to meet the 18 inch requirement.

In Texas the state SOP requires electric water heaters to be reported as a defect if they do not meet the clearance requirement. Check for any specific rules in your state.
