    Default DIY home fermentation fridge

    Hi everyone it's been a while since I visited, I have a question about a project I want to do, I am making a fermentation fridge the can control heat and cool to around 20 to 25, I was looking at eBay on the evaporator heat/cool fan, I would upload a pic but can't figure it out, I'm thinking having lines to a 12v pump going into a fridge for cooling and have line to a boiler for heating, any help if it would work or any other idea better or changes..

    When I was home brewing I had an old single door fridge which I gutted, layed it in its back and installed some wheels for ease of movement.
    I installed a single globe batten holder and a 25Watt globe and found it kept the inside within 2 (26 to 28) degrees day and night no thermostat needed.
    This was in the shed and didnt seem to vary much in winter or summer.
    I used to put the fermentation barrel in one side (I put a 90 degree bend on the airlock Valve) so I could close the lid, and put the recently bottled brew in the other half for the first couple of weeks.
    U may need to experiment with the globe size to suit youre fridge size

    Personally I wouldn't use a halogen lamp as a source of heat - firstly they're not very efficient and secondly light in your fermenting beer is bad... You can buy heat pads and wraps that plug into your favourite temp controller.

    My setup is a working fridge to keep the cool if needed, and a heat pad for warming. Both the fridge and pad go into one of those cheap STC-1000's and it does all the work for me. I also recommend having a small fan to keep the air circulating inside the fridge for improved efficiency and better temperature stability. I also use a thermowell in my fermeter so the STC reads the actually liquid temp and not the surrounding air

    Also look at the inkbird heat/cool controllers, then you just need a heater band for heating and the fridges compressor for cooling once you set the temp range.

    I use an old fridge and an ebay thermostat for raising Seedlings, particularly Bamboo which likes about 30oC.
    I have a light as it's good for plant growth but no reason you couldn't use something like an old fan heater if you didn't want to go to a heat pad.
    An old fan heater may be better than a pad as it would swirl the air around when it kicked in and I would think would keep the temp more even throughout the brew and reduce stratification of the air temp in the fridge. You could also modify one so the fan ran all the time and just the heater element kicked in and out for very even temps.

    Fan heater on low setting would probably only kick in for maybe 30 sec then shut off again and repeat as needed.
    There are a stack of the flebay controllers. I just bought a prebuilt one that is white with a short lead and a socket on the front below the digital read out and settings. Taking measurements with a calibrated thermometer the thing is very accurate, more so than I would have expected actually.

    You can also get them just as a board and could build up yourself with an enclosure and wiring.
