since warm air is on the ceiling i get better movement using a fan on the floor that blows up? i have been using small fans to bring air to the stove but am thinking i if i put this type fan in the room where it is 77-82 it might work since it is working like a ceiling fan??
it will suck cold air in shoot it upward which will warm it and push it out on the ceiling???

BINGO!! yes i am questioning myself and the common law of run fans on the floor TOWARDS the stove i know that in wide/long house you will need something to bring air closer but wondering if i put a fan in the middle of the room blowing straight up will that help air move faster throughout the house as i am bringing air into room along the floor AND pushing it out off the ceiling with the fan... might also reduce the amount of fans one might need????
 
Convection works best when there is significant temperature difference. The same with heat transfer. By bringing cold air to the stove, you extract more heat from the stove. Air stratifies, meaning it likes to keep to itself. If you place a fan in between the stratified cold and warm layers, all you would do is blend them and end up with lukewarm air which will not convect worth a damn.
 
What he is saying makes sense. Also, the rate and location from which the air is made to flow to the stove makes a difference as well. Often, success can be had with the lowest of fan settings.

Try a small Vornado fan. They are designed to mix the air and equalize the temps. throughout a room. I know mine work great in the summer to cool things off and have the rooms 'balanced'. Haven't used one with the insert because of ceiling fan and just do not want more of the fan noise along with the blower noise. Ceiling fan works great for us.
 
We do use the Vornado fan summer and winter and find they do a fine job.
 
I started the heating season with your basic desktop fan pushing cold air toward the heat source. It worked just ok. That fan died and my wife picked up a small Vornado. It made a noticeable difference in the warm air circulation. Now finding a fan during the winter is a whole matter altogether. Being a seasonal item they can be tough to find.

so how do you have your fans positioned? i have something similiar to that but don't use it cause i think it moves to much air even on low
