Almost certainly not. For purpose of comparison, you water heating will be about 1 million Btu (MMBtu or 1000CF of gas or 10 Therms depending on how you are charged) = 293kWh of electricity. If you check your electric and gas statements, you'll find those numbers. This isn't exact, but it's within 5% or so, accounting for efficiency and variations in conditions.
So 293kWh @ $0.12/kWh = $35.20
MMBtu at $1.20/therm = $12.00 (okay, $13 @ 93% efficiency)
An electric heat-pump water heater with an Energy Factor of 2.5 will produce that MMBtu for (293kWh/2.5EF)=117kWh, or about $14. Personally, I only run mine in std mode in the winter because it's indoors, so in the winter I pay $35, but in the spring/summer/fall I pay $14 *and* I reduce my a/c bill, making the net closer to ~ $8. I still pay more than gas, but last time I checked is was $7k to extend the gas line to my house, and that would never pay back. (note: these numbers don't account for thermal loss of my tank, so it's really ~20% worse, but you get the idea)
