Im in the process of building a fermentation chamber using a freezer. I have a dual stage temp. controller - what can I use as a heating element ? I was considering an IR bulb like you find on carvery units - any other ideas ?
Do a web a search for reptile warmers. Your hits will direct you to exotic pet supply stores. They use ceramic heating lamps in terrariums for lizards and such. I am headed that direction for my chamber when I build it. I will also add a fan for air circulation.
Also, some these places sell the bulk heat wrap sold as FermWrap at the different online brew shops. While I have never done it, these kits allow you do make custom sized wraps and the electrical connects appear to be some sort of crimp clip. Looks simple.
They are little heater with fans and sell at big box stores for about $14. That way they circulate air while heating for more even temperatures.
I did this for my chamber. Fan and heat in one package/plug. They have thermostat and fan speed settings and have safety features. Cheap, easy, and functional.
