A heating plant is a combustion engine not really any different then your car. Go on short trips what happens your fuel mileage is decreased. Go on the highway and it increases.
A heating appliance in general does not get to it's steady state efficiency or it's AFUE without a run time of between 6-10 minutes. Anything less you short cycle the burner.
You want long burner cycles not short burner cycles. Also by moving the air faster you increase the rate of that particular rooms heat loss though windows, doors or any infiltration point.
I agree that it will provide better comfort but any real savings no.
Sten your not pushing hot air your pushing cooler air. As you increase the convection you are cooling the down the air. The colder air falls quicker.
