Nucleophilic addition reaction of ketone to form alcohol - no acid treatment?
The nucleophile is the H-, a hydride. In your SP3 ketone, the tiny Hydride will have no issue producing a high yield of the alkoxide.

The heat will simply make the reaction faster and drive the equilibrium further.

Ethanol + water is a mild acid, so no issue with protons to complete your alcohol, and the heat makes that mix slightly more active as a proton donor.

You end up with a new equilibrium of your 2 alcohols competing for the proton, however with plenty of methanol and some careful washing with hexane or toluene you should be able to get your alcohol out of that mixture...
