This layer is hygienically clean and therefore suitable for permanent contact with drinking water. Unlike the stainless steel, rystal Enamel is resistant to pitting corrosion in the environment of hard and chlorinated water. Thermogen2 is the second generation of our exclusive insulating foam, which has been developed in cooperation with the company of ovestro, for attaining the most optimal heat- loss coefficients. The key here is a unique mixture tailor-made for our heaters. Its qualities are in line with all current and future trends in the field of heaters. It excels both in its insulating qualities as well as its shape integrity. Moreover, we are one of the first manufacturers in Europe able to meet the strictest ecological requirements of the EU, and thereby significantly contribute to protecting the atmosphere and the environment. The eramic Solution electrical heating unit is exceptionally resistant to hard and aggressive water and significantly extends the life of the water heater and storage tank under any conditions. This ensures the long-term stable performance of the heater system due to reduced limescale. DZD is a pioneer in this water heating solution; they have been using it in their products for over 50 years.

The KR thermoregulation box can be used in installations which cannot be controlled by a control unit from an external source; the KR box controls the external source or its switching elements (e.g. a three-way valve). The switching temperature can be set at between The water heater tank is equipped with sensor pockets with an internal thread of M 2 x.5 for the installation of the controllers sensors.
