As far as I know, they are plug and play, so you need a thermostat to prevent overheating. I use rheostats in some applications, but I don't think I'd use one with a heat panel. As other factors change, the heat at the rheostat setting can vary greatly. For example, if you adjust the rheostat so you're at 88 degrees, you did so while the ambient temp. was also at a certain temperature. If this ambient temperature drops, so will the "set temp." Alternately, if the ambient temps. go up from when you made your setting, the "set temp" will also rise. You will need to babysit the heat a lot more with only a rheostat. Hope that helps a little???
