Re: Move Water Heater
You can locate a waterheater anyplace that is convenient and that you can get the necessary access to the waterlines and an energy source. That being said, the garage is fine. A better place could be an interior closet or laundry room where access to existing water lines is more convenient, it just depends on how your house is laid out.
Instant hot waterheaters may be an option, though I do not know much about them to offer advice.
If lightning strikes are common in your area, then some research into lightning rods would be prudent. If this was a rare occurance, then I wouldn't worry too much about it.
