Hot Water on Both Electric & Gas

[grill-n-go]

Has anyone noticed a difference in the recovery time when running the hot water heater on "gas only" vs "both" (gas & electric)?

I've always used gas only until very recently when I finally found the ON electric button (duh!!!). (It only took me 4 years to find it).

First time we used both (electric & gas) and she (DW) ran out of hot water. I've always used gas only and we've never run out of hot water.

Does anyone know why, or if, there would be a difference?
