I'd like to attempt my first lager, but I don't have permission to take up room for another fridge/fermentation chamber. It's currently 56 degrees at the bottom of my stairs, so I'd like to cool the brew down just a bit more. I ferment in a sanke, so I thought possibly going with a peltier cooler, but I know they are very inefficient. My other option was to heat the brew in the garage to keep it where I need it. I'd like to get some kind of silicone encased heat pad, but I'll need to find one at a decent price. Any thoughts or suggestions or pictures to help me on my first lager would be great.
