Hot water is a basic need that is satisfied differently in every household. For example, it can be heated by a boiler, a solar thermal system, or by an electric hot water system. The latter has many advantages: The water is only heated when it is actually needed. This lowers electricity costs without sacrificing comfort. And since the distances between the hot water system and the tapping point are usually very short, there is hardly any heat loss.
Further advantages of electric hot water systems are, almost maintenance-free operation and relatively low purchase price.
The hot water systems are available in many power outputs.
