We had our system installed in Oct 2013. Ran it all last winter and did not use a drop of oil. Electric bills were up, but overall we saved money....but not a huge amount as our house is very energy efficient. This year, we are in a different situation. With NHEC increase of 29% on the electricity part of the bill and oil at very low prices of less than $3/gallon, we believe we are now in a situation where running our oil system will be more cost effective this year. So we are back on oil and will keep monitoring, but with high electric and low oil, it only makes economic sense for us to use oil this winter....unless oil prices really spike. But with oil now looking like 15-20% below last year and electricity up 29%, the spread is in favor of oil. I'd like to hear what others think. None of this reflects poorly on the Mitsubishi's....we love them and they work fabulously, but we will always make decisions based on the core energy prices.
