I really like the bottlecap top and the regulators in the lid. I'm in the process of planning a keezer on a 12.9 cu freezer. Did you have any trouble with it running too long or overheating due to having the wood right on the outside of the freezer?
I thought this could be useful for a mash recirculator, maybe even run a copper coil off the house water heater if the temps were stable enough. Has anyone tried this?
