bought a big chest freezer and a johnson temperature controller, but of course now its getting cold out and my garage isnt warm enough to keep the interior of the freezer above 57 degrees. the johnson controller has a setting, which i already switched, for heating instead of cooling. but im confused on what this does exactly... cold setting kicks the freezer on when it gets to warm, i get that. but if you switch it to heat setting, one would assume that it heats the freezer up when it gets to cold.... but a freezer cant warm up, its a freezer. (unless there's something about freezers i dont know)
> whats the best way to insulate/heat a freezer for fermenting?
>what exactly does the "heat" setting on the johnson controller do if the freezer cant physically warm up? is the controller used for different things besides brewing?
the best way i can think of is to switch it back to cooling mode and add a heating element to the freezer. does that sound right?
