at a 35% consumption difference between fuel oil/propane it would be a wash with fuel oil costing $1.65/gallon. This is assuming you're comparing same efficiency furnaces. There are oil furnaces that are 96% efficient so you would be better off with an oil burner if you can't get that price all the time. My area sells fuel oil mix for $1.99/gallon and $2.10/gallon for propane.Just filled my propane tank last week ,paid a buck a gallon. try to get oil for that. if you dont want to rent a tank then just buy it , then shop around for the best price.
thatç—´ why I bought my own 1,000 gal underground propane tank. I can have anyone I want fill it. Also I fill it in summer at lowest price, than heat thru winter. Our heating costs are down over 20% over similar heating when we filled every other month on rental tank. My furnace is 98% efficient. The exhaust pipe is 2 inch plastic pipe. Nearly no heat is lost.
At 100% efficiency you're producing the same amount of heat as an oil burner at 65% efficiency. My oil furnace is 88% efficiency rating so I would be getting 23% more heat per gallon of fuel oil.
