Industrial-Use (Low voltage) Rate - 57.88won per 1kwh (Incl. VAT, 1yr. avg.)
Diesel Fuel - 825won per 1Lt. (Incl. VAT, prices as of February 2003)
Heat Quantity of 1kwh of Electricity - 860 kcal
Heat Quantity of 1Lt. of Diesel Fuel - 9,200 kcal (Official government standards)
Assuming that a diesel fuel boiler with a heat efficiency of 70% is used and that diesel
  prices are 433won/1 Lt., the overall cost of energy is the same as an electric boiler.
  Electric boilers maintain a heat efficiency of close to 100% even after 10 years of use!
