Be careful of making assumptions based on where you live. It's quite common in
moderate temp climates to have the hot water heater located outside the heating
envelope of the house - i.e. in the garage.

Ours is in an unheated (and uninsulated) attic above the garage (a room that
I'm currently finishing into a workshop).
