500-liter hot water storage tank with high-performance heat exchanger for heat pumps

The SUNEX FISH S15 500X is a vertical hot water storage tank with a 500-liter storage volume, specially designed for efficient domestic hot water preparation in conjunction with modern heat pumps. Thanks to the extra-large smooth-tube heat exchanger with a heating surface of 4.6 m², this storage tank is ideal for larger single-family and multi-family homes with high hot water demands. ✅ Your advantages at a glance Extra-large heat exchanger (4.6 m²): Maximum efficiency with heat pumps and high flow rates up to 2,580 l/h at 80/10/45°C. High-quality enameling according to DIN 4753 and magnesium sacrificial anode for reliable corrosion protection and hygienically pure drinking water. 50 mm rigid PUR foam insulation with a gray outer jacket for low heat loss and energy-efficient operation. Inspection opening (Ø125/180mm) for easy maintenance, inspection, and cleaning.

  • Prepared for UV-20 disinfection system and multiple connections for temperature sensors and domestic hot water sensors.
  • Constant output: 105kW or 2,580l/h at 80/10/45°C – ideal for high simultaneous hot water demand.
  • Optionally available with a titanium anode instead of the standard magnesium anode.
  • Robust steel construction (S235JR) with automatic welding process and high operating pressures (storage tank up to 10 bar, heat exchanger up to 16 bar).

    • 🏠 Areas of application

    • Hot water preparation in single-family homes, Multi-family and two-family homes with high comfort requirements. Combination with air-to-water and brine-to-water heat pumps for energy-efficient domestic hot water heating.
