Heat Source For a Small Fermentation Chamber

Has anyone used a forced hot air heating and cooling system for their fermentation chamber? I searched and could not find anything. I'm building a small chamber in my basement and the duct work is right there, so it got my thinking. I do that for a living so the work would be very easy for me, I just wanted to know if anyone else had any pros and cons.

Thanks!

I do pretty much the same thing to cool my ferm chamber. I pull cold air from my keezer. I don't see why using hot air wouldn't work, though you may want to be careful about hot spots (don't blow hot air directly onto the carboy/bucket).

In a well insulated chamber, it takes very little heat input to maintain temp. My chamber has a volume of about 24 cu. ft., and I'm heating it very successfully with a 100 watt infrared reptile bulb controlled by my STC-1000.

I got a couple of the seed germinating mats that go under the germinating trays at the hardware store. They are very water resistant and spread the gentle heat of a fairly large area so you don't get hot spots or temp overshoot issues either. The STC will control it nicely too. I just wrap in on the bucket and use an old T-shirt to hold it in place. Worth a try, anyway.

I have a 15cu ft upright freezer for my ferm chamber, and I just use a regular 60w incandescent table lamp inside to generate the heat. Of course, I live in S. Arizona, so it doesn't get too awful cold here. However, I do find that when I have a batch that is actively fermenting, the heating almost never runs. It's a really shoddy setup right now because I don't have a proper lamp (I just have it propped up in a box), but you can see how simple it is.

They make those reptile heaters that are enclosed in ceramic too so no light will shine out as well. Saw it on good eats.

I use a small ceramic heater in my upright freezer.

I picked this up for $12.99 at walmart. It's small and heats up the freezer nicely, plus it doesn't put off any light.
