Most hot-water tanks hold app. 30 litres of water (app. 2 showers). We therefore recommend that you spread the showers, if more than 2-3 persons need a shower. However, some houses can be equipped with two hot water tanks.
Switch on the hot-water tank by adjusting the temperature button to central position. The heating takes about 30 minutes. If the water isn’t heated, the overheating fuse can be turned off. It is reconnected when you press the little button under the hot-water tank or a separate switch by the hot-water tank.
