You can set your Smart Schedule for Hot Water the same way as for heating rooms.

On the Home tab, you can divide your day into multiple time blocks and set a setting for each time block.

For many heating systems, you can turn your Hot Water only on or off. If your system supports it, you can also specify a temperature for each block.

On the Away tab, you can specify the Hot Water setting for times when nobody is at home.

Usually, it is sufficient to specify one setting that is active during the night and another that is active during the day. In combination with the Away setting, this setup minimizes the required heating and at the same time ensures that you always have Hot Water when you need it.
