What size is your firebox?

2.2 Cu Ft heating just under 700 sq ft of somewhat drafty cottage. We usually keep it around 70/75, however it's been known to hit 80 on occasion (last Saturday it was in the 30's for the first time in a while and the stove got a little overloaded for the outside temps/sun and hit 80) and once it dipped to 49 (last winters polar vortex, before we laid attic blanket and did a lot of sealing).

1.4 Cu.Ft advertised, but closer to 1.0 Cu.Ft actual, heating 1100SF ranch, reasonably insulated.
Stove does a good job, but requires fairly frequent loading. Living room in the low 80's with single digits outside.
I do wish I had a cat stove.

3.2 cuft heating 2100 sqft, 2 stories over an unfinished basement, 22 windows, 2 sliding glass doors. I believe, most days I could hit 100F if I TRIED.. but.. well.. no.

We use a LL Bean firewood bag thingy, I don't know how many wheelbarrows it converts to, but 2 bag loads a day if the temps are near average.. 3 when it gets cold. We will see single digit lows for the next couple of nights, and highs in the teens and low 20's.. those will be 3 load days.

3.0 + 2.4 cu ft heating 2600 sq ft of drafty old farmhouse. Interestingly these stoves have exactly the same size top. One just has a narrower firebox.
