Your $15 dollar fan if used 24 hours a day, (like my Ecofan is used) will use about $23.00 per month of electricity. That number is from these PSNH charts. Don't be fooled by the 50 hours they show for "average monthly use" we have our stove burning 24-7, 720 hours per month, from mid October to mid march. ( 5 Months )

The 3 blade model is $127 with free shipping on Amazon.
So the math (for us, your results may vary
) After a $15 dollar fan, and $23 a month electricity, the Ecofan was a "push" in about 5 months and all "profit" for the life of the Ecofan. (We've had ours for 3 full heating seasons going on 4)
Plus fans are noisy, even the best ones, and the Ecofan is completely silent.
So we're several hundred dollars to the good vs. a fan.
