If they are the same size and brand of heat mat, you can plug the t-stat into the wall and a power strip into the t-stat then plug the heat mats into the power bar. HOWEVER, they must absolutely be the same brand and size of UTH, or they won't maintain the same temperature.Thank you everyone for your input. I'm on my way right now to my local pet store to buy a thermostat. My only other question is, do I have to buy two seperate ones since I have two set ups? Or would I be able to get one and hook it up to both heat pads?
