The Hydropool 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 their 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.
Energy Efficiency
Hydropool hot tubs are engineered to be the most energy efficient swim spa in the world, providing 100˚F / 37˚C for pennies a day.
Self-cleaning technology
ENERGY EFFICIENT FILTRATION
Your Hydropool hot tub filters 100% of the water every 15 minutes. This means that the hot tub does not have to be operating as often in order to filter the same amount of water as our competitors, making it the most energy efficient filtration system in the world.
Hydrowise heat shield hardcover
MADE FOR CANADIAN WINTERS
This heavy-duty safety hardcover contains an insulated baffle in the fold area, locking the heat in and the cold out.
Insulated thermal shield blanket
NASA-INSPIRED TECHNOLOGY
Triple thermal shield technology uses aluminum foil to reflect heat back into the hot tub, as well as black backing and pipes designed to maximize heat absorption. This very same technology is used by NASA to protect its astronauts from the -270 degree cold of outer space.
Low amperage evergreen pump
HIGH FLOW, LOW ENERGY PUMPS
Our pumps are engineered to produce high flow rates with low energy output, resulting in filtration that is 26% more efficient than the competition.
Eco-heat exchange technology
FULLY ADJUSTABLE VENTING
Each pump creates 1.5 kW of waste heat and our triple thermal shield blanket reflects that heat back into our hot tub cavity.
HydroWise thermal vents maximize energy efficiency for any season and any climate.
Programmable controls
Select your desired water temperature and your hot tub will automatically maintain this setting while conserving as much energy as possible.
Designed to exceed CEC regulations
SETTING THE STANDARD
Hydropool hot tubs are ranked in the top three globally for stand-by wattage and energy efficiency, and were one of the first to be approved under the strict California Energy Commission regulations.
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).
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.)
