Standing AISI 316L stainless steel tank for heating and storing domestic hot water. The indirectly heated tank is suitable for producing domestic hot water. The internal coil (heat exchanger) is a permanently welded smooth tube coil, which can be connected to a heater, heated buffer tank, or solar collector system. The tank body is suitable for connecting a backup electric heating element and a magnesium anode (element and anode not included). The tank has a cleaning flange on which periodic maintenance can be performed.

The insulation is available in several versions:

- Removable soft polyester insulation (F) for 800–2000 liters, with a zippered PVC cover on the outside.
- Non-removable hard closed-cell insulation (R) for 150–500 liters, with an ABS cover on the outside.
- Hard, but removable polyurethane shell insulation (FC) for 800–2000 liters, with a PVC zippered outer cover.

The maximum permissible operating pressure of the tank is 10 bar for 1000 liters, 6 bar for 1500–2000 liters. The heat exchanger can be used with a maximum pressure of 12 bar. The maximum operating temperature of the tank under pressure is 95°C, the heat exchanger can be used at 110°C.
