<p>The method involves automatically and/or connectively transporting heat through a substance provided in a porous chamber via a porous medium in a liquid or gaseous physical condition. Improved mobility of the substance is used for transporting ability in the liquid or gaseous physical condition. A temperature of a heating element is controlled so that energy delivery of the heating element is maximized corresponding to a preset temperature during changing a heat conductivity of a surrounding.</p> |
