Whole neighborhoods here with heaters in the attic.
All along the a gulf coast, thousands of them.
If the attic is ventilated it doesn’t get too hot.
On custom homes we put large custom build pans, With 2” drains. Relief lines get piped to the outside.
Frankly a water heater leaking upstairs isn’t any worse than a toilet tank cracking on a toilet or a supply line blowing out.. And both happen quite a bit, just ask any plumber.
Not all heaters blow water when the fail, most drip a small amount of water.
Usually you find gas heater’s leaking before electric.
I had a choice between gas or electric and I chose electric. I had multiple reasons why I chose electric, all in my favor.
Texas wouldn’t have had a problem if the infrastructure hadn’t (electric grid) failed.
People could’ve died, never mind the plumbing.
The power companies in Texas turned a bad situation into an impossible one.
I move them out of attics sometimes. But that poses challenges that most homeowners frown on. I have some customers that want them moved TO the attic.
@Mitchell-DIY-Guy its not that I don’t value your opinion, I do. I’m just offering a different perspective. I’m not quick to judge because we as individuals have many different ideas and different experience that shape our Opinions. I like hearing an educated homeowners opinion. It helps me prepare for tough questions., most of my customers are very educated.
