Description

The HSRS domestic hot water storage tank offers all the advantages of the HRSS domestic hot water storage tank but features two coil heat exchangers, making it ideally suited for bivalent heat supply systems, such as solar systems.

Features

  • Insulation option (must be ordered separately): We recommend this type of tank only with certain reservations when used in conjunction with a heat pump! This is because the “low” flow temperature of the heat pump (usually 50–55°C) can lead to limitations in hot water comfort. We recommend our EHSWP tank, which was developed specifically for heat pumps!
  • With two smooth-tube heat exchangers (1-inch tubes)
  • Highest build quality
  • High-quality S275JR steel in accordance with EN 10025, manufactured in accordance with EN 12897:2006
  • Enameled in accordance with DIN 4753
  • Operating pressure: 10 bar
  • Test pressure: 16 bar
  • Maximum operating temperature: 95°C
  • Up to a 5-year warranty (with proof of maintenance)
