Regency f 3500 cat stove here is a chart of red temps inside the stove green the stove top. The top is blower on bottom blower off.
That is a good point with room temp and yes a lot of variables to compare, outside temp I do have on this chart, but need the exact in house conditions like no oven on for example. I only have the chart for today my thermometer does not go that far back.
After back to back 24 hour burns the graph shows room temp yesterday morning with fan on and this morning fan off similar conditions except the burn with fan on I believe had one piece of wood less, yesterday morning room temp was 64.6 fan on this morning 68.4 fan off.
Arent you also worried about heating other rooms? Hence the fan moving more heat to other spaces?

I didn't see this thread until after I posted on the BK thread, but I'm wondering how much difference there is in flue temps between blower and no blower, i.e. how much additional heat is staying in the house using the blower?
I don’t have a flue probe, but temps in other parts of the house I do have a graph of a sensor in the room next to the room with the stove. The room with the stove is 32 by 19 with 10ft ceiling.
Nice, like the data!
Room temps and heat demand would be a variable, however, I think it's obvious that by far the biggest variable is the amount of air circulating around the stove. As you pull heat off faster, you'll get cooler temps. The other vars, relative to fan/no fan, will be comparably small.
What would be an interesting graph is letting each of these play out to the same temp to try to measure total heat delivered, and whether or not they're different, but I think that would necessitate a probe into the flue.

so your saying that without the blower your getting better temps in the house ? I'm interested very much so because if your just using the radiant heat to push through house it would take longer ? correct ? now brings me to my question . i have a ceiling fan in the room with my insert will i get warmer air through the house with blower off and fan on ? thank you guys in advance
Ok here’s the chart for inside temps and in the stove temps fan on and off.
This is inside temps green line is inside red line outside temps 4/20 at 8am the inside temps was 68 fan off on 4/21 7am same outside temps fan on inside temps 71. Same amount of wood for over night burn.
Inside stove temps fan off.
Inside stove temp fan on.

This is from last winter but I’m thinking from the data and observing this fall burning that with the blower on it delivers heat faster around the house but as the wood burns down the fan cools off the stove and temps may drop faster around the house. So if I’m doing 24hr burn times no fan on colder days fill with more wood open air little more but fill stove more often. Will continue to look at date and report. But discussing, experimenting and learning is half the fun at least for me.
I'm wondering if there is a sweet spot or good compromise by running the blower on lowest speed?

The fan-off run enjoyed a very significant 10-15° advantage in outside temps, so I wouldn't be too quick to call it better.
