I'm considering buying a 47 gallon Rheem short electric tank water heater: PROE47 S2 RH95. I've worked out the measurements and it will fit under my front steps, about 6' above the garage floor. Currently, a 40 gal tall gas heater sits on the garage floor about 10' to the right. The space under the front steps is concrete on top of grade.
- I would need to add additional concrete so that it's level (or build a 2x6 platform).
- I would need to remove the short studs shown, and add a header to open the space for access.
- I would need to make accommodations for drainage, either to outside or to the garage floor drain.
Besides being a pain to raise the empty tank 6', what red flags do you see with this plan?
The goal is to open up more garage floor space. I've considered tankless, but I want to switch from gas to electric and I've learned my 150A panel won't accommodate electric tankless.
