You could run into hop utilization issues or problems with DMS if your using Pilsen Malt.
Looks as though the OP is offline for now. To help answer your question about boiling. I have a 1500w element in my HLT. As a test I heated 5 gallons of water for around 55 minutes. Water got near boiling, maybe 210F, and after that period didn't seem to do much but boil water around the immediate area of the heating element. I don't know how much longer it would have taken to actually bring the water to a roiling boil. I turned off power at an hour.
