Does Hot Water Optimizer change my room heating?

Hot Water Optimizer

No. Hot Water Optimizer affects your hot water only.

The feature adjusts the temperature range your system uses when reheating your hot water. Everything related to your room heating stays exactly as it is:

  • Your room temperature settings are not changed

  • Your heating curve is not changed 

  • Your heating schedules are not changed

If your room heating ever feels different, this is not related to Hot Water Optimizer. In that case, check your heating settings in the ViCare app or contact Viessmann support.
