Looked for similar threads but couldn't find anything so apologize if this was discussed before.
I spend a lot of time tuning my stove this year and adding in ductwork to recirculate air and believe it's close to optimal. The stove is enclosed in a small 8x8 room pulling in air from above living area through ductwork, releasing it at floor level next to the stove. A fan mounted in the ceiling (the floor of the area above) blows s hot air from the ceiling, through the floor joists, under a large kitchen center island which is vented on 4 sides. Kitchen is tile and can get a nice 80+degrees which is amazing for radiation and walking around barefoot.
Question I have is what's the relationship between discharge air temp and how much voltage is applied to the blower motor? I would think there's no need to reduce blower voltage because it only reduces CFM, albeit at a higher temp. To me, running 150 CFM @ 180f out is no better than say 200 CFM @ 170f and I would think the more CFM output the better, even though discharge temp lowers.
I know the "system" is pretty good because I can have a discharge temp of 180f, the living area above at 80f, yet the temp at mid level in the stove room barely gets above 80f while foot level is 70f and ceiling level is 120f. Weird having cold feet and a hot head when walking in there and I assume not much wasted heat heating up the stove room. I always run my blower @ 100%, regardless of feedrate/airflow setting and wondering if there's a benefit of reducing it to get a hotter discharge temp. If not, why is it even adjustable?
