I am amazed at the accuracy of the weather predictors. All week they said it was to drop to -41 on Sunday. AND IT DID! I had to move the thermostat from 1 to 2 but the house is still warm. Man oh man am I glad I went with the KING! With the thermostat at 2 it burns wood faster but still only having to load twice a day, once in the morning, once before bed.
