The heater is now set so low there is not enough hot water for a bath. I asked the manager, who said there is a rule that for children and old people they cannot set the water hot because of scalding risk...their suggestion was to heat boiling water on the kitchen stove and then carry it to the bathtub! (No risk of scalding there?)

So I watched some YouTube videos, This Old House, and hope I learned the basics...

But you have to turn off the breakers, and then test that the electricity is truly off, and I have no gadget for that...so I am thinking, just turn the breakers off at night, and then if the water is cool by morning it is okay to go into the hot water heater?
