The iDM fresh water station en-sures a comforting supply of hygienic hot water in a matter of seconds.

The stainless steel plate heat exchanger guarantees long durabi-lity, high corrosion resistance and first class hyigienical standard.The insulation used for the iDM Hygienik

range, which incorporates a fleece and soft foam sheath, prevents a „chimney ef-fect“ from occurring in the buffer storage tank.

HEAT PUMPS FROM AUSTRIALeading technology from iDM. Expertise from experts.

1) No energy effi ciency class is stated, as storage tanks with reservoir content >500 l are not within the scope of the EU-Regulation No. 812/2013 for energy labelling of space heaters and combination heaters.

THE ENERGYFAMILY

CONTROLLED HGL TECHNOLOGY WITH HYGIENIK FRESH WATER HEATING.

FIRST-GRADE TEMPERATURE LAYERINGFOR FRESH WATER CONSUMPTION:

iDM heat pumps save costs because the controlled HGL technology means more than 85% of the energy is fed into the heating circuit at 35°C. The second section reaches a temperature of 60°C, and the content is made available for hot water preparation via the Hygienik tank with fresh water technology. Water is only heated when hot water is tapped. The water in the storage tank is for heating only. As a result, hot water is always fresh and the formation of microorganisms such as Legionella and other bacteria is prevented.

• The storage tank is cooled from the bottom up• Higher temperatures remain available in the top area• The perfect layering is visible in the diagram by the severe

drop of the lines

• Very low return flow temperature in the storage tanks• Drain up to 1,800 litres of hot water at 45°C (if the 2,000l

storage tank is full at 60°C)

OUR FRESH WATER TECHNOLOGY ENSURES ENHANCED COMFORT AND WELL-BEING.

iDM Hygienik combined storage tank:Water is only heated whenever you need it. The only water in the Hygienik is for heating. This means that your hot water for drinking, washing and rinsing is always fresh.

Conventional hot water tank:See below the warm water that is stored in the tank for a prolonged period of time. Mud and dirt are deposited at the bottom, which is an ideal breeding ground for germs.

Comfort through hygieneThe Hygienik buffer storage tank is a 2-in-1 layered storage tank: hot heating water is available for heating the drinking water in the upper section. The separate, 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 stainless steel plate exchanger on the outside of the Hygienik system transfers the thermal energy from the heating water to the drinking water in the kitchen or bathroom, fast and hygienically.

The benefi ts to you: you use the energy from the heat pump for heating and warm water, you have no issues with Le-gionella, and you can shower or bathe in complete relaxation. This is how your energy use brings more quality to your life.

Info: Legionella are pathogens found in water. They multiply rapidlyat temperatures between 30°C and 40°C and can cause Legi-onnaire's disease. Legionella is a serious infectious disease of the lungs which can be fatal for anyone with a weak immune system.
