Is DualSun compatible with the BOSCH Compress 4000 or 5000 DW-C thermodynamic water heater ?


Yes, DualSun SPRING hybrid panels can be paired with BOSCH Compress thermodynamic water heaters:

  • CS4000DW 200-1 CFI

  • CS5000DW 270-3 CFI

  • CS5000DW 270-3 CFO

For optimal coupling, it is recommended to schedule heating time slots by the thermodynamic group compatible with the customer's consumption habits and solar heating hours.

  • Showers in the evening: 4 p.m. to 11 p.m.

  • Showers in the morning: 02:00 to 08:00


The solar temperature sensor is to be installed in the thermowell (4) as shown below:


The coupling between the solar regulation and the thermodynamic water heater intelligence is not possible.
