Haven't bought any oil for 3 years now. House is warmer. Saving thousands a year. We don't heat our basement. It is an old fieldstone basement and doesn't freeze. We do keep heat tape on the kitchen water pipes but we had to do that before with the furnace anyway because they are in a crawl space. When we bought this house 17 years ago it was $25 a month on the budget plan for oil. The last time we put 100 gallons in our tank 3 years ago it cost $400 and we used 3/4 of it in one month.
