Do you have anything to support that claim? Because in my belief this follows normal thermodynamics, which means that if the energy dissipation over an amount of time is less than the energy cost to heat, it makes sense to do it. Do you think there is no relation between the thickness of the insulation and the time it takes before reheating is more energy efficient?
