I had a gas stove (used natural gas) back when I was married and living in Newport News. My stove was brand new with no whistles or bells. It didn't take more than 7 minutes for it to get up to the temperature. Actually, I'd turn the oven on and then put in what was to be baked.
My electric stove takes around 10 minures or so to preheat. I usually turn it on before I finish getting things ready to be baked.
Even when I lived in Richmond and used older gas stoves I didn't have to preheat the oven before I used it.
