My problem is that the oil in my tank was expensive so to stop burning pellets would cost me more until I get through the expensive oil. I have 3/4 of a tank right now. Then the question is will the price of oil still be low by the time I burn through what I have???? Seems like it will be but right now the price here in mid coast Maine the price of oil is $2.29. I think it would need to get to $2.00 to make it worth switching.
