Default Fermentation Chamber Heater

I'm looking to build a fermentation chamber out of a 5 cu ft chest freezer. Hopefully thats enough space (I'm going to measure first).

Anyway, I'd like it to be a dual stage chamber (heat and cool). So, obviously I have the cooling part handled, but I'm unsure about what kind of heater to put in there. I've seen people mention it before, but never went into detail.

So, what type of heater can I put in a 5 cu ft chest freezer under a dual stage controller?

i recommend a fermwrap. its very low tech but works. just plug it into your controller.

I use a 60w light bulb. Bought a cheap socket and cord fr ~$6. Works great. (I ferment in stainless so light isn't an issue).

light bulb works, need more heat, just go with higher Watt.
just put a fan to circulate the air.

5cu maybe tight. you may have to remove the hump.

I use a resistive heater fan I bought at home depot for $12. I have used it in two chambers now and love it because it moves the air around.

Current chamber:


Also if you have any wiring or install questions about the LOVE TSS2-2100 they are answered in my side-by-side build thread linked in my sig.

I use a similar heater to Boerderij Kabouter (dude, spelling that sucks! ) I have a fermwrap somewhere, too, but it's a pain trying to get it in good contact with the conical.

I use an old hair dryer that SWMBO donated to the cause when she got a new one . Works great, and you can adjust the fan speed and heat to make sure it doesn't overshoot temps too quickly.

Why does that sound like a fire hazard to me?

I've wondered about doing something like this too...but wouldn't condensation in the chamber pose a risk for an electrical fire with one of those heater units? I guess you could use one of those EvaDry units in there (I have one in my keezer and love it) but then that's one more piece of equipment to worry about.......

Not sure how it could start a fire when I have it set anywhere from 32 to 68 degrees... the hair dryer is on the "warm" setting which is as cool as it goes. Can barely feel the heat when you put your hand in front of it. I don't see how that'd be any more of a fire hazard than the space heater that others are using. Not to mention the fact that a hair dryer has a GFCI breaker built right into the plug.
