<p>A water heating system includes a heat exchange chamber having an internal cavity and a water coil within the internal cavity of the heat exchange chamber. A magnetron generates microwave energy and is in communication with the internal cavity. A hot air control system draws the heat generated by the magnetron into the internal cavity. The hot air control system includes a valve which is selectively opened and closed to control the passage of the heat generated by the magnetron through the internal cavity.</p> |
