Generally adding a bit of water will result in a bit less soot; you'll generally get a bluer flame. But hotter? I doubt it. The water acts to cool (slow down) the combustion process, resulting in a cleaner but not hotter burn.

I haven't experimented with the exact proportions. Generally the alcohol I'm using for fuel already has about 5% water in it, and that alcohol burns pretty cleanly.
