I have had the pleasure of telling my oil company to never deliver oil. I heat the house with my wood burner and lacking any built in air handling devices, I circulate the hot air with two portable squirrel cage fans, works pretty good.
The wood burner room is around 74 degrees, the rest of the house around 70 degrees. In the process, I save about $200 per month not counting free firewood I pick up due to my service business,and the $80 oil delivery fee.
I am sure you are aware of this growing trend particularly in the high heating oil usage areas.
