I called my utility to find out. 2 phone calls and 4 transfers later....

In residential use 220 isn't going to save you anything powering motors or anything else.

The difference comes into play for industry. Based on a demand billing and power factor it now makes sense to use it. Residential isn't billed on either.

I wondered about this big savings that I've seen written in magazines but it was never explained why 220 would save you money.

Its always mentioned it saves but never why it saved anything.

746 watts is about 1 hp.

6.7 amps for 110

3.3 amps for 220.

Less amps but its still the same billed wattage. Its still 746 watts.

The only saving seemed to me to be starting amps between the two but it should still be almost the same wattage in either case.

If you convert your KWH bill into amps.

Even if the amps are lower your "charged" more for less amps. It costs 2 cents per amp at 220 compared to 1 cent for 110.

Wheres the savings there?

I started thinking what would it cost to add a 220 circuit, buy the plugs and recepticals and figured 220 would have to save quite a bit to be a savings. Now I might use 220 for my electric furnace but it would be just as easy to run 2-20 amp circuits at 110 as one dedicated 220 circuit.

For my wood and metal tools same thing. Why run 220 all around the basement when I can do the same at 110 and have useable outlets?
