Does anyone have any information on efficiency of airtight fireplace doors vs an insert? Fuel in vs heat out.
Is there any reliable way to calculate such a thing or does the fireplace variables make it impossible?
Country Flame indicates 30k btu from their firedoors. How do they calculate that and how would you find the efficiency?

This compared to an insert such as the Jotul which lists 65k btu and 71% efficiency.
