Hot Water Tank Woes

My unit isn't enclosed...just mounted to the wall in a corner of my garage. It's mounted because of earthquake laws.

I have a 3 car garage so it's a pretty big space.

 

I'm just thankful for hot water heaters no matter what kind they are or whether they are in a home you rent, or own. Taking a hot shower or bath is a blessing I really enjoy.

 

I guess I take it for granted because Ive never not had hot water. There are many people who don't.

 

@Bobby Cole "You brought up a great point @Frank Sanoica, and one well fit for a bit of good research."

And I, being the sloth that I am, asked for your knowledge about this, rather than research it myself. Thank you for the answers, I agree with you.
