Probably, but at 140 degrees you'd want to drive a steam turbine and
generate more electricity. Unless of course you have lots of reactors
and need to do something with surplus night time thermal energy.

Close to 140 C, but that would be inefficient. You'd probably want to
heat the water to 80-90 degrees or so.
