Heat tape made for reptile tanks is basically the same thing as fermwrap but much cheaper. You can cut it to the size you want and easily tapes flat to surfaces. I have some of this that I use as a wrap like fermwrap but there's no reason why you couldn't tape it to the side of your freezer. It's designed to lay flat under reptile tanks. It only gets 10-15F hotter than its surroundings but in an insulated and closed container it will get warmer but not fire danger hot.

I bought a 200 W "desktop" ceramic space heater at Wax-Mart for about $9. Has a built-in fan and thermal cutoff so that it won't set fire to anything if the controller fails.

The Inkbird is the way to go IMHO. I have one for my homemade glycol chiller and it works perfect. I have not needed to use the heating side. I have verified the accuracy of the unit with the calibrated temp gauge on the fermentor. At a cost of around $40 I believe that is the way to go!

I use a ceramic heater like Sean. I hook it up to my old Johnson controller and it heats the 22 cu ft chest in no time. I also use an a/c unit thick cardboard box over my floor vent. Add fermenters and it is easy to do Belgians and such. Start at room temp, slowly ramps over 2 days, add box, and ramps to high 70’s to finish. Cheap and Easy as it gets.

That's what I use too. Mine is about 6 X 6 X 6 inches, and I run it off my 2 stage Ranco. If you get one be sure it only has analog controls, otherwise it will reset when the controller turns it off, and sit there looking stupid the next time the controller turns it on.

The cooling circuit on my fermentation chamber is all I use.

When the weather gets cool and I actually need heat, I just throw an electric heating pad in the chamber. My pad has three power settings and I just dial up enough heat to keep the chamber from dropping lower than my desired temperature. The cooling circuit will kick in as needed to keep it from overheating.

The heating pad does not need to be controlled.

The heating pad I own automatically shuts off after two hours.

Looks like you selected poorly. There are still pads that don't have auto shut off.

This question comes up pretty regularly.   I use a hairdryer.  No light, and it circulates the air.  On top of that it is cheap.  With all those advantages, I don’t know why it is not more popular.

The circulation idea does sound good.   The one downside I see is that a hair dryer draws a lot more juice than a Fermwrap, lizard rock, etc. if that's a consideration.
