On your show today, you mentioned booster fans to a listener who wanted to heat a garage workshop. I have a similar requirement but have been unsucessful in finding a source for such fans. I need a fan to fit in in a 12" diameter hot air duct. Can you suggest any sources?
Answer:
Any big box store will have such a fan for you but because the duct you're dealing with, you may have to go to a firm that deals with them in commercial buildings. I see them being used to heat airports and the like.
