| ▶
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!
