I have a question about my water heater, there is nothing wrong with it and am not having any problems just a curious question.
You know how there are two lines at the heater ( one for cold water going in and another for hot water coming out)
I have noticed that when I feel the cold water line its cold to the touch as the water goes into the tank but after a while it feels warm too?? why is that? is it just residual heat from the heater? I juts happen to notice that before.
