Re: Cost Savings?
Remember that you pay by the killowatt hour. Key word being Watt.
Perhaps you should juggle Ohm's law for a bit and see what you come up with.
EDIT: Oh yeah, I forgot to tell you...Volts X Amps = Watts.

Re: Cost Savings?
Even if both heaters (110V and 220V) are of the same wattage, there will still be a (small? too small to measure??) difference in operating costs. First of all, the 220V version will draw less current, so there will be a lesser amount of power lost in the wiring from the power panel to the heater. This will save some money. Secondly, and more importantly, it is likely that the two will have different efficiencies. In other words, both may draw the same power, and cost the same for every minute they are running. But one may do a better job of converting the electrical power into heat. That heater (it could be either the 110V or the 220V) would be running for less time, during a 24 hour day, and would therefore have a lower overall operating costs. But efficiency is not a function of voltage, it depends more on the manufacturer?s choices (e.g., materials, type of heating element, construction quality, etc.). I suggest looking closely at the catalog cut sheets, before making your choice.

Re: Cost Savings?
I don't know if you are asking as a matter of comparison or if you are considering a new installation.
110v heaters supplied by the same size branch circuit may require additional branch circuits, depending on your load.
Also, don't forget to check your service to be sure it is sized adequately for the additional load of your electric heating system. You may find that your service will require upgrading.
While these are not operating costs, they may be costs to be considered.
