One KW of electic heat = 3412 BTUs so it takes 40.7KW to equal the BTUs of one gallon of diesel (139,200 BTUs). So, at $0.10/KW one might assume that diesel would have to be $4.07/gallon (40.7 X .10 = $4.07) BUT while the electric is 100% efficient,
the diesel boiler is maybe 80% ( educated guess) it will take 1.25 gallons of diesel to equal the same amount of electric heat from 40.7KW.
At $0.10/KW it's cheaper to use the electric if diesel is $4.00 assuming 80% efficiency.
At $0.12/KW it's still cheaper, but not by much if diesel is $4.00.
At $0.15/KW diesel is cheaper again assuming diesel is $4.00 & 80%.
The cost to run is dependent on how cold it is and for how long.
