This is my first post, but not my first rodeo, not peltier project. That said, it is not finished yet. I thought I would let you all know my peltier based conical is silent and works like a dream and does not cost me that much to run. Anyway, I made a few different peltier projects, both are in progress, but I have brewing with them. I have attached some photos of my peltier cooled conical fermenter. It runs at about 146 watts and runs me about $50-100 a year a according to my "kill a watt." What do you all think? I would be happy to help others.

I would be happy to do so. I think the most important thing when using the peltier is removing the heat from the system, and the best way of doing that is to use liquid not air. So I have a dual loop, one hot and one cold, system. Basicly I have sandwiched the peltier between two watter blocks. The cold loop consist of a pump, a reservoir, water block, and a copper coil that wraps around the fermentation chamber. The hot side replaces the copper coil with radiators and fans. The cheapest and most efficient that I have found happens to be large heater cores from cars. If people want I will start another thread, I don't want to "hijack" this one. I have just been working with these things for a bit and after a lot of trial and error I have learned how to make the peltier work pretty dam well, or so I think. The best thing is how silent it is, the only thing I can hear is my refrigerator running and this thing is almost completely silent.

I have a photo of the conical after I made a custom stand for it and before I put all of the stuff on it. I think this photo makes it easier to understand.

The water blocks that I use on my conical fermentor are from CPU water blocks and it holds one module. The ones I made are from aluminum square tubing, 3/4" with mitered ends to create a pathway for the glycol to run. I have some photos of the blocks next to an for scale. I hope to one day use the arduino to run it via a phone app so you can start laggering while on vacation.

I am not certain on my physics, but I think if I use this setup on a stainless conical it would be more efficient than the thick walled minibrew that I am using now. Also I was wondering about using stainless tubing to create an immersion/submerged cooler so it was a better transfer of the coldness to the beer without contacting it.

Oh, and yes it may use more power than a fridge, if you have the space for a freezer then go for it. As for me, I started off making this because my condo has only so much room and I could not manage to bring myself to have a third fridge for beer. I have a small one for bottles and a my kegerator, not to mention my main fridge. Little did I know the world that I was entering.

I have an idea of using the peltier along with ice jugs that would run at certain temp ranges. May be that idea would be even cheaper to run?
