This evening, I didn’t quite make a fire when I came in. Usually the case is, let the daughter play while that fire gets built. Well after having dinner, watching a movie, it was apparently still cold after almost 30-45 mins of a starting fire. Now we’re about an hour from when I started the fire and just finally warming up. It’s not even considered cold out in comparison to you others... Hypothetically questioning, how long would it take for your house to warm up if you had let it get down past a cold point? The cold point for the house was down between 55-60F. Yours could be considerably lower.... Even with my small house,I don’t open my rooms up until the stove room is well above 72°F. In fact, the only way this house gets balanced is to open the rooms up, and the heat flows quite quickly when there is nearly 30° difference.
