<p>The invention concerns a water heating or cooling device, consisting of two juxtaposed tanks, the upper tank (1) designed to contain a water reserve, and the lower tank (2) equipped with heating or cooling means and designed to treat a volume of water. The invention is characterised in that between said two tanks, is provided a sealed slide valve (3) sliding between the two tanks (1) and (2) so as to allow or inhibit the water contained in the upper tank (1) to flow by gravity towards the lower tank (2). The inventive device is further characterised in that the water supply of the device can be provided as the user wishes, either by placing a bottle of commercial water in the upper tank (1) or by directly filling said tank.</p> |
