Very good information. Just to give you guys some idea of inside temps. My house is a new two story box around 2300sqft. My thermostat is in the same room as my stove is. Around 18 ft away from the stove. That room temps average between 80-85. Upstair bedrooms around 71-74. We like it hot. To me watching tv in the winter with temps around 80 is nice. We also have a fan in that room that I keep running. Best investment I have ever made. It exceeded my expectations.
