Revolutionary insulation system

Our engineers put their heads together and came up with the idea to copy the technology from NASA.....For years Hydropool has used a full spray foam technique to insulate their hot tubs, but recently there has been an advance technology created that can have huge benefits to our customers.

No matter how cold you think it can get in Canada, nothing compares to being in outer space.  Space temperatures have enormous ranges, from +300 to -300 degrees.  The space program has spent millions developing an insulation technology that will allow for safety of an astronaut in these temperatures.  We figured, if it can handle -300, it surely can handle anything Canada can throw at it.  Sure enough, when we began to incorporate this thermal technology system, it dramatically reduced heat loss.  Not only did it reduce heat loss, but it also allowed us to add another thermal shield to our system.             (See figure 1).  We have always used a vapor barrier securing the tubs plumbing, this allowed for our plumbing to remain the same temperature as the body of water.  It also allowed for much easier access to our plumbing in the event of a leak.  A win win....for our customers.   

With the new technology available, it freed up more space in the cavity of the tub, thus allowing for an additional thermal layer.  By insulating the floor and the cabinet we were able to use the pump heat to heat in the cavity, therefore creating an additional thermal layer to add to an already outstanding insulation technique.  (See figue 2).  This system also allows for control during the warmer months using a venting system, which will help cool the pumps.  (See figure 3)

first thermal shield
  
second thermal shield
  
adjustable thermal vents
 
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.
         
       
 
HydroWise Hard Cover and Polymer Base
  
programmable controls
  
 
The hot tub is capped off with our HydroWise 4" cover on the top and heavy duty Polymer Base on the bottom. This completely seals the hot tub to ensure maximum durability and efficiency.
  
Your Hydropool Hot Tub does not need to continually operate. Select your desired water temperature and the hot tub automatically maintains this temperature while ensuring that your hot tub is automatically conserving as much energy as possible.

Hydropool uses this system for both Self-Cleaning line and Serenity line.

Typical per-unit-thickness R-values for material

R-values per inch given in SI and Imperial units (Typical values are approximations, based on the average of available results. Ranges are marked with "–". Clicking on SI column sorts by median value of range, clicking on Imperial column sorts by lowest value. Third column are real SI values that are not per inch. Based on the units, the two last columns should have a conversion factor of 5.71. In practice, the numbers will have been measured using different methods.)
