Unfortunately I never ran the oil heat before replacing with the heat pump, so I can’t give a real world example.

However, theoretically Heat Pumps are just as cost effective in CT as gas per BTU, averaged over the year.

Some quick math, for 100,000 BTU’s of heat, assuming a 95% efficient Gas/Oil Boiler/Furnace, it would be $1.30 for Gas, $2.15 for a Heat Pump, or $4.56 for Oil (at $6/gallon). The Heat Pump however really shines in Summer, where it can cut your electric bill by 50% over using window AC’s or a standard whole home AC.
