Well ive have yet to use the fan on my stove really this year. hasn't been really cold. but we have had a few low 20 nights. but i have a finished basement setup. insulated really well good windows. and some holes in floor to go upstairs. well it seems like im actually getting better heat on my 1st floor than when i run the fans. i feel like when i turn the fan on it pushes the heat off forward and cools it off a little as well. in my setup i dont really need the heat pushed forward off the stove. i just need it to rise up. and i feel its doing that better without the fan. just wondering if anyone else has the same results? time will tell, when it gets even cooler.
