For everyone with flat panel heaters: I just bought one, but I don't know where to install it. The ceiling height is about 7ft. I'm using the deep litter method so the shavings are about 6 to 7 inches deep right now. Should I install it on the ceiling? Will it provide enough heat? Or should I install it on the wall? or will it be too close to the shavings? I really don't want to burn down my coop/garage or house!
