AKOMA Heat & Breeze Dog House Heater and Fan Outdoor Chewproof Cord . Condition is New, in open box. I purchased this about five years ago, as a backup, if I ever needed it. I have a kennel building now, so it’s not needed anymore. Comes without instructions, I lost them. But, it’s pretty self explanatory, plus, it’s available on the akoma site. Additionally, it does not come with mounting screws, but I’m sure you’ll have some laying around.
