I take it you are outdoors? I would say root temperature is the more important factor rather than the ambient air temperature when it comes to growing plants, so using a water heating element will help you keep plants with warmer temperature requirements if that's what you're looking for. It all depends on what Asheville's winter temps are like and what plants you are looking to grow.
