# Would it be possible to concentrate thermal energy of a water bath?

Suppose I have a basin of water containing $1000$L that's at a temperature of $310$ K. Now I'd like to put this thermal energy to good use (say set a cup of tea or a hot bath), would I be able to concentrate the thermal energy of this water in to a smaller basin so that the temperature of that basin gets to be $360$ K?

Now, I know that heat pumps do this with air, by relying on evaporative cooling. But in this case I'm specifically wondering if such a system would be possible when medium one takes energy away from is water?
