110v vs 220v for pool pump.

So a 220v wired pump will burn the same watts per hour as a 110v wired pump? Pumps being the same HP.

Yes, except the higher the voltage the more efficient, very very small in this case

Will a 220v 1HP use the same watts per hour as a 110v 1HP?

With everything being the same, yes

I never truly understood electricity, I just knew it hurt lol

So the only true benefit to wiring a pad 220 for a pump is the motor might last longer?

Better pump choice at 230v

Note that you don't say watts per hour.

Watts is energy used per unit of time.

Watts ÷ 1,000 is kilowatts.

The power company charges for total energy used.

Total energy used is kilowatts x hours. So, the power company bills for total kilowatthours.

A pump that uses 1,000 watts uses 1 kilowatt. Every hour that it runs adds another kilowatthour.

1 watt is 1 joule per second.

Energy can be measured in multiple different units. Such as, joules, calories, btu etc.

Power is the amount of energy used per unit of time.

So a 220 v pump will in fact use less watts per hour than a 110v?

They both use the same watts.

My point was that, when talking about power, you just say watts, not watts per hour.

Well, I think this whole string of responses confused us newbies even more than when the question was originally posted. My pump is already wired for 220V and I'm not an electrician so I'm not going to touch a thing...

I’m gathering you must of been or are a teacher or professor. My point was about costs, not about joules, watts or whatever. My head hurts, I’m going to lay down now lol
