People used to burn home heating oil in their Diesel cars and trucks.
Now it is the same or even more than Diesel at the pump- that has 40+
cents/gal tax on it. I switched to heat pumps from propane in 2000 and
haven't regretted it. How much is your propane? I haven't checked here--
imagine it is over $2.00/gal. I still have the propane for the cooktop,
and the furnaces which only fire up when the HP's go into defrost.
