Cold water alone will not drop your temperatures eight degrees. You will need ice packs. A more readily available option is to go out and buy a case of water bottles from the store, freeze a couple of bottles, and just rotate them out every 6-8 hours by placing them in the water of the swamp cooler. Take an old cotton t-shirt and pull it over the top of ...

The aquarium heaters are not heating all of the water, but only the water around each heater. This will form convection currents around each heater - the heated water only moves upwards, and rises up to the surface, at the same time water at the surface cools and sinks. The convection currents are probably only a few inches around each heater, depending ...

While not the most elegant, you can go through the lid in a larger fermentor without a thermowell. I put this together without wanting to incur the cost of a thermowell - so I used some electrical tape, an extra hole opposite the airlock and a rubber grommet. I patiently and accurately wrapped the tape around the sensor wire, building it out so it fit nice ...

You have to find out what material the chiller is made of and then you can find the proper cleaner to use. If it is stainless almost anything that isn't chlorine based would be fine to use. Aluminum on the other hand doesn't fare well with oxygen based cleaners. If it is copper oxalic acid would be best such as the product bar keepers friend.

I do winter ferments in a big plastic tub (called a "muck bucket") full of water. I put the fermenter in that and put a 65W aquarium heater in the water. If it's really cold, the heater runs 24/7. when it's not so cold, I out it on a timer to come on at the coldest parts of the day. With ambient temps in single digits, I can keep steady temps between 50-...

I think that it depends a lot on the yeast you're using, the beer you're using it in and where that beer is in its life-cycle (:D). If you made a particularly large starter of especially hearty yeast and it's at day 2.5 peak-Krausen, it will take a lot more abuse than a beer on it's third week in primary made with 5th generation yeast you underpitched. ...

I don't know how I would go about drilling a hole and fitting it with a bung for a thermowell, so I decided to simply nail a hole in the lid and permenantly attach the DS18B20 probe using a sealant. My mom used to make and sell aquariums, and she suggested using silicone glue. Here is a post on my web page detailing the step-by-step and including all the ...

I like the idea of taping the thermometer to outside of the bucket and adding a layer of insulation over top so it is more closely registering the beer temp and not the air temp.

I also use a water bath for controlling fermentation temps. I found a bluetooth weatherhawk temperature sensor that reports to a mobile app and it is waterproof. So I built an stc 1000 temp controller to selectively switch between an aquarium heater & small recirc pump on the hot side and a peltier liquid chiller on the cold side.

As mentioned before, using a swamp cooler is an excellent idea. In addition, if you work long days like me, and have no AC, like me, and your ice has dificulty maintaining the cooler themps you want, like me... you can add a small fan or even a box fan, blowing on a beach towel draped over the fermentation vessel thats dipped in the water. this adds ...
