Hot water storage tanks - domestic hot water storage tanks for heat pumps in sizes of 200, 300, 400 and 500 liters

Vertical hot water storage tank for domestic hot water preparation. The tank features a large-surface heat exchanger for a heat pump. The contact surface between the hot water and the tank is protected against corrosion by a layer of high-quality enamel and a magnesium anode*. Complies with DIN 4753. This ensures that the domestic hot water only comes into contact with a hygienically clean surface.

Advantages of SUNEX hot water storage tanks

• Constant hot water supply: The storage tank ensures that hot water is continuously available even when several taps are used simultaneously.
• Efficient heat transfer: The FISH S15 storage tank is equipped with a large-surface heat exchanger that enables fast and efficient heat transfer – particularly useful in conjunction with heat pumps.
• Compact design: Thanks to its compact dimensions, the storage unit can be easily installed even in small rooms.
• Hygienically clean service water: High-quality materials and the DIN 4753 standards ensure a hygienically clean surface of the storage tank, making contact with the service water safe.
• Flexible installation options: The hot water storage tank can be installed flexibly and adapts to the local conditions.
• Durability: Robust construction and high-quality insulation ensure a long service life and reliable operation.
• High comfort: The constant and reliable hot water supply maximizes everyday user comfort.

Thermal insulation

The thermal insulation in the storage tanks consists of a layer of CFC-free polyurethane rigid foam and a replaceable layer of PVC jacket.
