An air space between the hot tub shell and Polyfilm Barrier is the first air pocket. The Polyfilm Barrier supports the pipes and retains the waste heat energy created from the hot tub plumbing and the hot tub shell. We then install the first thermal seal blanket to create the first Thermal Shield. |
|
An air chamber is created between the first Thermal Shield and a second layer of Thermal Seal Blanket that is installed on the inside perimeter of the hot tub cabinet (5000R excluded). This air chamber allows the excess heat created by the evergreen low amperage pump(s) to be utilized resulting in reduced operating costs and forms the second of two Thermal Shields. |
|
The air chamber that is created by the two Thermal Shields may cause the hot tub to overheat. Adjustable Thermal Vents are installed to exhaust the heat in the warmer months and retain the heat in the colder months as required. |
