Proportional T-Stats will definitely work with all heat pads. If you have any heat pads with three prongs on the electrical plug, you'll have to ask when you order, specifically for a "grounded" model. I personally don't have any heat pads (or flexwatt) with that three pronged plug, so it wasn't an issue for me.Originally Posted by BigCeC43
