New Hampshire Climate Audit has a cost compare web page.

One can input their own costs and efficiencies to provide an accurate comparison for your situation.

My own propane group buy rate of 1.47 and a 90% efficient system yields propane cheaper than the tool's basic oil cost. That would change with a good group buy of oil, of course.
