I am looking to pick up a fridge for controlling temps. Are there any particulars I should know about when buying a fridge or is any old fridge good to go? I am also thinking of buying a chest freezer and I am interested in comparisons between getting a freezer and a fridge.
I am planning on using a Johnson digital 2 stage temperature controller. I also plan on heating the unit with this http://www.williamsbrewing.com/BREWERS-EDGE-SPACE-HEATER-P518.aspx during the winter months. Ideally this setup should be able to accommodate both ales and lagers.
