Don't know if you have an apartment or a yard, but I have a little kiddie pool I fill with water (3.5' x 10" or so) and set my kettle in there. works very well in the wintertime, especially if you fill the pool the night before, and brew in the morning. I set the boil pot in the center of the pool and give the wort a good stir. Stir the pool around a bit, too. That is a lot of cold water I didn't use electricity to cool. I'll buy a wort chiller when it gets warm outside.
