How It Works

The A. O. Smith Air2Heat water heater moves some of the heat from outside to provide hot water inside. To move the heat, the A. O. Smith Air2Heat water heater works like a refrigerator in reverse.

While a refrigerator pulls heat from inside the refrigerator and transfers it into the surrounding room, the A. O. Smith Air2Heat water heater pulls heat from the surrounding air and transfers it into a tank to heat water.
