I believe the point he made was that P =V * I no matter the way you approach the questionKonowl wrote: ↑Dec 12th, 2016 9:04 amSo you conveniently pick and choose to make your comparison?
Yes, obviously you are correct in your comparison. It is just as easy for me to retort by saying "yes, but a 2000 watt baseboard puts out much more heat than a 1500 watt baseboard", but now we are arguing semantics. Not to mention the wiring involved etc as it would require it's own circuit.
You can still achieve 2000 watts on 120 volts.
Now if you mean most houses don't have 20 amps breaker and the cable gauge required to avoid burning down the house... then yes you must switch to 240 volts above 1800 watts
