My brand new tank specifically says an insulating wrap is not needed and voids the warranty.

Yea 99% of the new tanks out there do not need any additional insulation on the tank. All of the energy efficiency requirements that have to meet put them in a much different category than even a tank that is 10 years old. It's the pre-2000 tanks that have been well maintained and are still working that can benefit from a tank wrap.
