Here is more on the calculation and comparison. Math shows 32 kilowatt is equal to the 110,000 btu. Assuming a kilowatt costs 10 cents the 32 kilowatt will cost $3.20. The comparison is for the same amount of heat you have available it will cost you $6 for diesel or $3.20 for electric. Consider you have no burner, fuel tank or chimney to maintain. Electric looks like a better choice. Electric may get you tax credits too.
