How To Insulate a Hot Water Heater

The process of how to insulate a hot water heater begins with understanding how heat moves from a colder surface to the warm surface of a warmer one. One of the easiest ways to understand this process is to imagine yourself standing in a freezer, where cold air rises while warm air descends. We rarely ever consider the process that makes the temperature in the colder space equal to or greater than the temperature in the warmer space because it is easier to focus on the ice that is dropping from the top of the freezer than on the movement of the air up and out of the bottom of the freezer. Understanding this basic physics will help us as we learn how to insulate a hot water heater.
