The elevated volume of air moving across the stove's surface is causing better heat transfer efficiency. I believe this was the original poster's intention.
Then the OP should have used words more appropriate to that end. See the capital P in Produce in the subject line. The word should have been "induce" (as in for example: induce the potential for more heat given that voltage must remain constant), not produce.
A new riddle. How many BTU's would a resistance heater produce if a fan was blowing across its resistance element to lower the resistance, but the power company did not assure constant voltage, but rather allowed the voltage to drop and instead guarranteed that you would always receive a constant current flow?
I = V/R
If the current flow stays the same the BTU's stay the same. Energy (the number of flowing electrons) in = energy (BTU's) out
