I doubt the whole house is that temp, in our house with two stoves I have yet to get the 'new side' of the house with the Rockland over ~71*F and thats with it burning at 600*. Thats in a large great room. The 'old side' of the house with the freestanding stove will get the stove room into the 80's with a good burn but one room away and your dropping pretty quick. We dont turn on the A/C when it gets into the 80's either, well except for the one window unit in my sons bedroom (finished attic) since it gets very hot there (if it was 80 out it would probably be 90 in that room). We have one other window unit that we have put in different rooms the last two years but it doesnt run much at all. I like having it cool when I try to sleep during the day in the summer (when I'm on nights) since its so hot in the day and I need my sleep but I can't stand the noise... unless its a 90* day I tolerate the heat better than the noise.
