I forgot to post this earlier in the summer. It's almost time to start heating the house again! Even with the mild winter that the west coast had this year we still managed save some money with the new 92% efficient gas furnace. I adjusted the estimated oil usage to reflect the warmer temperatures but kept the same delivery dates and called to get the current prices on those dates.
Estimated ’09-’10 cost of heating the house with oil: $632.50
Actual ’09-‘10 final natural gas bill: $336.76
Dollars saved: $295.74
