HVAC Members.. Need Help With Simple BTU Calc.
Fireplace heat exchanger…
– 1200 CFM Blower > 3″ Square Duct Inlet > Air Heated Inside of Fireplace To (Estimated 400 degrees) > 3″ Square Duct Outlet.
How many BTUs are being produced, assuming no duct restrictions…
Can you even pump 1200 CFM through a 3″ Duct? Is there a limit… Wondering if I should run at 600 CFM instead to save power.
