Ability to raise temperature from 5 to 20 deg F from ambient.

This unit provides ideal temperature for year round brewing, fermenting, and wine making in cold conditions. Convenient and easy to use, simply place on a flat surface, put your fermenter or carboy on it and plug it in.

Space Heaters:
Homebrewers have been known to use smaller power space heaters as a heating source. These can be had in the 100 watt range which equates to around the same wattage as a strong lightbulb. There are potential safety issues to consider using this type of a heater. If you’re considering one of these, I’d recommend contacting the manufacturer to ask about your intended application.
Temperature Controllers
These work in conjunction with your heating and/or cooling devices to help you control fermentation temperature. Although this post is generally focused on cooler temperatures, you can gain further control by using a dual stage unit to control both a heater and a cooling device. That means you should have good control year round.

What size ReptiTherm would you suggest to bring a standard sized fridge up from 45 to 50 degrees?
I would go with the medium or large size. I think small could probably swing 5 degrees, but it would be a slower reaction than the medium or large versions.
Great Thanks!
You should really point people here instead: http://www.reptilebasics.com/heat-tape
I bought two feet of 12″ tape, and clips, all assembled and shipped for $17. And the 12″ tape is 23 Watts/ft. Cheaper than any other deal listed here. It has worked out great for me so far.
Nice tip, are you putting this under your carboy / bucket or just some place in your fermentation chamber?
I just put it in my fermentation chamber (a deep freeze).
I use these also but have them taped to my bucket fermentors
