American Whirlpool 460

Northern Exposure® insulation system

A patented thermal barrier technology which recycles the free heat energy for more efficient heating, and lower energy costs. All four sides of the hot tub, plus the floor and cover are lined with reflective copper material to reflect radiant heat energy generated from the pumps back into the hot tub. Heat is absorbed back into the plumbing, helping raise and maintain water temperature. Finally, the entire exterior of the hot tub is wrapped in 3M Thinsulate™ Insulation, the same incredible material utilized in winter clothing. This three layer patent pending system ensures energy created by the hot tub stays in the hot tub.
