Combi indirect storage tank with one heat exchanger 500-2000 liters

The combined hot water storage tanks are used for heating and domestic hot water supply of alternative sources. The outer buffer tank surrounds and heats the inner domestic hot water tank. Their large domestic hot water storage capacity makes them very suitable.

The KFN types have no built-in heat exchanger coil.

The ZVN types have one built-in heat exchanger coil for solar collectors.

The KFF types have two built-in heat exchanger coils for alternative heating sources.

The glassy smooth inner ceramic surface burned on at 850 Celsius prevents the corrosion for a long time. The organic impurities and lime scale have hard to stick to the fine surface resulting longer tank life and healthier water quality.

The 100 mm thick polyurethane foam insulation minimizes energy losses.

Large built-in anode rod offsets electrolytic corrosion due to dissolved mineral salts and other contaminants thus protecting the tank and the threaded connections effectively.

Electric heating element can also be installed.

Maximum operating pressure of the domestic hot water: 0.6 MPa (6 bar)

Maximum stored domestic hot water temperature: 70 ° C

Maximum operating pressure of heating medium:  0.3 MPa (3 bar)

Maximum operating temperature: 95 ° C
