240 volt cheaper than 120 volt?


We just installed a 6' 240 volt baseboard heater (hardwired). Will electrical consumption be less that using the plug in 120 volt electric heaters we used to use?

Best Answer

No. 1000W heater operating cost will be the same, either way. However, a 240Vac heaters generally use less copper (smaller conductors for lower current), so theoretically you save few cents on the purchase price.
