Which is more efficient

  1. Jan 10, 2005 #1
    Hi Friends,

    Is any body please tell me which heater is more efficient (which one I have to choose in order to reduce my electrical bill) 220V electric heater or 110V electric heater for the house or if I choose 1500W heater in 110V or 220V is that make any difference

    Thank you

    Ideally there would be no difference (same power, same bill), however the 220V heater will waste less power in heating your house wires. So, 220v is better.

    The last answer omits the fact that most of your house wiring would also be heating the house. You would gain more by considering how heat is lossed.

    Just so you know why, wattage is the product of volts times amperes. So a 1500 watt load designed for 110 volts will draw 13.64 amps, at 220 pulls 6.82 amps. As mentioned, the only difference is slightly more or less heating of the house wiring.

    What do I need in order to use 110V 50Hz air condition to a place which has 220v 60Hz

    What do I need in order to use 110V 50Hz air condition to a place which has 220v 60Hz electrical system?
    Is that possible?
    If yes How?

    Please help me

    Thank you
