I have been burning my stove a little bit here and there when its cold enough and i feel like the heat is much less than people lead me to believe. It is comfortable in the house, but its not really that cold yet. I have the stove in my concrete basement so i expected some loss of efficiency, but i also bought a stove twice the size my house needed. My thermometer i have on the top of my stove is constantly close to the over burn zone(Should i go by that?). The air in my house feels thick to me now. I might be crazy not sure. And on top of that I'm half afraid to leave the house with the stove running. I guess i will get used to the air in the house, my wife thinks its fine so that's good. I hope its not unrealistic to heat my whole house (1500ish sq feet) with a harman tl300. Sorry for rambling guys, let me know what you think. Thanks.
