Type I for Selection : Save electric charge by selecting this when equipment
  operation is moderate.
Type II for Selection : Save electric charge by selecting this when equipment
  operation is high.
High Voltage A : Consume more than 3,300V but less than 66,000V of voltage
  supply
High Voltage B : Consume 154,000V of voltage supply
For electric boilers, single-phase current instead of three-phase current, and
  220V instead of 380V or 440V, save more money in terms of interior wiring costs
  and are more trouble-free. Hence, the higher voltage is the better.
Cost of increasing electricity : In case of increasing electricity by about
  20kw. (Internal wiring costs is charged extra.)
  Underground supply region - approx. 100,000won/kw
  Electric pole supply region - approx. 90,000won/kw
