I need to get a handle on how much heat a fermentation produces so I can work out how much cooling power I can get away with.
My cunning plan is to use one or two of those Peltier effect membranes that heat one side and cool the other side when a DC voltage is applied, and reverse the effect if the voltages polarity is reversed. These are the things that 12 volt cooler boxes have in them, but they are not all that powerfull. The advantage of using these things would be they can double up as a heater and a cooler, you just reverse the polarity........Oh, and I can get hold of them for free....
So, does anybody know how many watts of heat a 5 gallon fermentation kicks out at full pelt? (pun intended)
