Who Says You Use a Freezer to Keep Things COLD?

I keep my chest freezer in the garage. This is less than ideal in the summer when the garage is hot and the freezer has to work extra hard to maintain ale temperatures. But it pays off in the winter. When I brew lagers.

Since the surrounding are in the 30s most of the winter, by adding a small ceramic heater, switching the temp controller from cool to heat, and dialing in my fermentation temperature (48 F) I can use a very small amount of electricity to hold a nice steady temp.
