First year heating and I love my Kuma it's done a great job keeping my main living area warm but I'm having trouble getting heat into the kennel room (see attached photo). Opening the door does work but my goal is to keep dog smells and dirt in the kennel room. I'm thinking of installing an 820 CFM thru wall fan (example attached) to move some heat in there. I'm regularly able to get the main living area in the upper 70s and just trying to keep the dog room in the high 50s maybe low 60s. House is new construction great insulation. Any folks have experience with this?
