I don't think any heating device that uses electricity makes sense as far as dollars per btu output.Here's a chart from the US office of energy that is great for comparing energy cost.Wish there was a wood value.I don't know what efficiency rating they use for the fuels but electric is 100%.You can plug in different energy costs for comparison.
Fuel------$ per million BTU------Cost of fuel
Oil--------18.24-----------------$2.53/gal
Gas-------11.86-----------------1.18/therm
Propane---27.19-----------------2.48/gallon
Electric----41.38-----------------.14/kilowatt hour
