Abstract
A self-protecting heating system comprises an electrically conductive medium, an alternating current source and at least two electrodes. The alternating current source is in contact with at least one electrode at each pole, and the electrodes are in electrical contact with the electrically conductive medium. The electrodes are made of passive metals or passive alloys. The electrically conductive medium may be an aqueous solution or water. The system is preferably provided with a thermostat that disconnects the electrical power from the electrodes once a desired temperature has been reached.
