1. The price of each energy may change when a factor occurs to change it.Electricity rates are based on general electricity (Gab) and low-voltage electricity in winter (November to February), and progressive tax is not applied. 2. City gas (LNG) rates are based on the heating rates for homes in Seoul, and rates may vary depending on the region. 3. The above rates are as of February 2012 (based on heating a space of 3.3㎡ for 30 days, 8 hours a day) 4. Energy consumption may vary depending on the insulation at the site of installation in different heating methods and environmental conditions.
