I wanted to do floor heating but was talked out of it. Told me KS isn't right for it due to temp swings. You'd turn it on during a cold day, then it would be 60 the next day. Problem being that once all that cement got warm it would take forever to cool back off. Then you'd be stuck with a hot house on a hot day. Looking back, I wish I would have went ahead and done it though.
Place is looking great!
