NO, if you have motors that are 'convertable' -110 or 220/240, the higher voltage is more economical.

It costs the same regardless of whether the voltage is 120 or 240 volts. The bonus of using a higher voltage is on the installation wiring costs. At a higher voltage the current of the device is lower. This lower amperage permits a smaller size wire to be used. This only really becomes a cost saving factor in larger equipment. In small power tools the higher voltage range will allow you to double the distance from the supply source to the place where the power tool is needed.
The higher the voltage , the lower the current. eg. take a load of 15 amps @ 120V = 1800 watts. Same load of 1800 watts @ 240 volts I = W/E 1800/240 = 7.5 amps. There is money to be saved on big installations when you can reduce the wire size in half.
Yes you can save money by decreasing wire size (not always cut in half though nec tbl 310.16) but electrically ( energy wise you are not saving a thing, Voltamps are voltamps I dont care how you do the math !) Example : 15 amps @ 120 volts = 1800 watts ( voltage x amperage ) so does 7.5 amps @ 240 volts = 1800 watts of power same amount of electricity will be used at either voltage. Best advise is to call an electrician.
Yes and No.
Electricity bill will be the same, the only way you can save by using 240 V appliance instead of 120 V assuming Wattage is the same is during wiring of electrical connection.
Not directly. You would either need to step up the voltage using a transformer or have a 240V receptacle installed. Most homes are actually supplied with 240V in North America which is split to produce two separate 120V legs with a Neutral Center Tap. The voltage between these legs, however, is still 240V.
Not without using a step down transformer. Applying 240 volts directly to any 120 volt rated device is not wise. The manufacturer of equipment states on the manufacturer's label what the correct voltage that is to be applied, to make the equipment operate as it is designed to do.
yes 240volts is 240 volts
You don't.
Yes a transformer should be used. The steam table needs its correct voltage otherwise on 240 volts it will operate over its given specified nameplate wattage. A 208 volt heating element run off of 240 volt will have an output increase by 75 percent.
If you mean a dual voltage motor 120/240 then yes these will operate on a 240 volt home distribution system.
Yes, if the motor is rated 240 volts 3 phase.There is such a thing as 240 volt 3 phase power.However if you are asking if you can use 240 volts single phase on a three phase motor, then the answer is no.
240
It won't run.
yes 240volts is 240 volts
No, a 240 volt device runs on 240, and a 120 volt device runs on 120. Attempting to run a device on incompatible voltage results in damage.
No, unless the motor was wound for dual voltage operation, which it will state on the motor nameplate, a 110 volt motor run on 240 volts will be damaged.
You don't.

No. The 1-phase 240 setting on your computer's power supply is for the 240V wall outlets in other countries. The 240 outlets in your home are 2-phase 240.

Yes, 120 and 240 volts can be run in the same conduit.
