No, problem. You probably could, hopefully someone that lives in a colder climate can chime in a bit, because I really don't know with the temp ranges. I do know that RHPs have the ability to creat a hot spot and that would be my main concern, but if you set them to 80 it may be fine. The guy at pro products is really really good and if you call him and give him the specifics that it asks for on his page, he will be able to tell you everything you want/need to know and more. I would say that he would be your best bet as far as information goes and making sure you do it right the first time around. Good luck.
