Dear T.,
If you are in the City of Ft. Lauderdale and on city water, then you don't need to boil the water unless your pediatrician says you need to...the water is perfectly fine.
You also don't need to actually heat the water to make formula. If your daughter likes it a bit warm, just use very luke warm water to make it. Put formula powder in bottle, put water in and shake it.
I never warmed my son's bottles, didn't have time and he didn't care.
Best wishes, C.
PS My pediatrician told me not to use bottled water to make formula because it doesn't have flouride in it and that is the reason so many toddlers have cavitities these days. We just had our 3 year old dentist appt and so far, no cavities!!! YEAH!
