The Do-It-Yourself Home Energy Audit, Part 1

if the water heater tank is inside (indoors), do I need to insulate pipes?

Very educational, thanks

@2006soccerguy Yes. The hot water in the pipes is probably at least 120 degrees and your home is probably 70 degrees or so. That means there's still a pretty good temperature difference and possibility of heat loss.
