I have a small one-room bungalow with 3000W of baseboard heating and woodstove heating. I'd like to "move" that heat to my basement. It's poured concrete with 100% R10 exterior foam and 70% R5 interior. I have considered: adding a duct with fan assist to blow air from the ceiling main floor to the basement, or adding large floor registers and trying to use my ceiling fans to circulate warm air. Does anyone have suggestions on which would be the best option, or would another approach be better?
