I think you said it Iceassin. I've been struggling with multiple types of buddy heaters when I could've just bought a sunflower way back and saved all that money. I might just sell my buddy heaters.
For ventilation, my shack has those two flaps on the top of it. Are those sufficient to ventilate?
It should be. I kinda go by how much cold/fresh air I am feeling. I don't like it blazing hot to begin with so a "little" chill doesn't bother me. Let's me know I'm safe.
