The Hygienik is a 2-in-1 layered storage tank: hot heating water is available for heating the drinking water in the upper section. The lower section features the buffer storage tank for low-temperature heating. When the hot water in the shower, basin or sink is switched on, a plate exchanger on the outside of the Hygienik system transfers the heat from the heating water to the drinking water; fast and hygienically.
Your benefits: you are using the energy from the heat pump twice, are not affected by Legionella bacteria and can take a relaxing shower or bath. Only the water quantities that are actually required are heated up without storing hot water temporarily. This prevents the formation of micro-organisms, such as Legionella and other bacteria.
The Hygienik provides fresh, hot water in seconds: it heats up from top to bottom in layers. This quickly increases the temperature in the upper section to 50°C or more and hot water becomes available within a short period of time.
The heat is used in reverse sequence: the bottom section cools down first, heat always dissipates towards the top. Hygienik makes use of this with intelligent, layered storage tank technology. A speed-dependent pump at the fresh water station ensures the hot water has been equally heated up and the return to the bottom section of the storage tank is permanently cold.
Deposits form in conventional boilers that may become a reproduction area for Legionella bacteria and other pathogenic agents. iDM Hygienik technology does not store drinking or service water, but exclusively heating water. Fresh water is stored in small quantities in the piping and the plate heat exchanger. This gives pathogenic agents no chance – and you always have hygienic fresh water available.
