Desalination is a different process to heating though, for instance the sea won't lose excess salt to the atmosphere.

The sea does lose salt to the atmosphere, just less than it does of water, so it doesn’t reduce salinity. Wave action releases enough salt to smell salt in the air, and a bit makes it up higher to provide cloud condensation nuclei.

Wow! I didn't know that.
