I live in a mobilehome and I have a 6 month old GAS water heater
outside. I thought the water heater ONLY comes on when you use the HOT
water. I heard it come on this morning at 5:00 AM(it was really cold
outside) do not know if that makes a difference. It stayed on for 15
minutes. Is this normal? thanks

Your hot water heater is outside?

We first off, you need to protect it from the elements.

Second off, you need to insulate the **** out of it to control you
heating costs.
