In summer? If its not getting to cold for you.

In winter yes also if its not getting to warm for you, but also heating water is easy enough. But you don't need that much hot water

Potentially also cooling down your fridge more and your freezer. But that is not that much energy.

While that works, it would still be quite a waste. It would be a lot better to save it and discarge it later
