Does anyone know of a product, like some kind of mat, that you plug in, lay on your driveway and heat snow and ice away? I am very familiar with hydronic and electrical heat systems that go down before concrete / asphalt is poured; I need a solution that can lay on top of my driveway. Being in a condo, well, you get it. Can't mess with driveway. Only thing I can think of is to hang infra red bulbs off my deck which happens to extend a few feet over the drive and see if their energy reaches.
