What is your rule on when to burn???

Anytime I would have turned the furnace on before. Generally below 68 interior unless I know it will warm up do to good weather during the day. Have been burning every night since late fall though.

We burn on evenings and weekends from late sept. thru april. Ours is located in our finished basement, it often feels cold and damp. The nice bi-product is our main furnace does not run as long as the outside temp stays above the teens. We absolutely love the dry heat...

Usually my first light up is right after I get the bill from the Oil delivery man. Actually it's a few minutes after that, when the shock wears off. I use the receipt to start the fire.
