Free Heat Insulation System with Heat Lock

Arctic Spas Request Info for Free Heat Insulation System with Heat Lock

Insulation in the right place saves you money, every day!

  • Constructing a self-supporting shell allows Arctic Spas to insulate differently than everyone else - the same as we insulate our homes
  • In our homes we insulate the exterior walls, the floors and most importantly the attics of our homes and we tuck everything important to us within this insulated envelope
  • In an Arctic spa, ambient heat from the pump penetrates the spa shell and heats the water. In winter this heat returns to the pump area in the event of a power loss thus creating the FreeHeat System With Heat Lock. 
  • Arctic has always believed that insulation below the water surface is of small value if the areas above and directly to the sides of the water are not adequately insulated (seriously, doesn’t heat rise?)
  • The “attic” of Arctic's design is its Mylovac cover, which at 5” of thickness and featuring a full-length baffle is capable of retaining even more of your energy dollars.
  • High density polyurethane foam is applied to the cabinet walls and lip underside to a thickness that stops heat loss
  • Arctic finishes off this insulation envelope with the same foam applied into its floor systems. Then, we place all our equipment inside this cocoon, creating a perfect, stable Heat Lock operating environment.
What About Full Foam Hot Tubs?
Because there is insulation that fills the cabinet and is applied to the shell, heat cannot circulate and transfer to the water in a full foam hot tub.  As a result, the heat cannot be recycled and they are not as efficient.
Insulation on Shell = Energy and heat is wasted because it cannot transfer through the shell to the water
Full Cabinet Insulation = Energy and heat are wasted because the heat has nowhere to go except to be vented to the exterior

More Innovation

Arctic has taken its insulation to the next level. Already the best insulated cabinet in the world, its FreeHeat & Heat Lock Insulation system did not escape the exacting eye of its engineers. Arctic's overlap door insulation design removes the last opportunity for heat loss and captures even more residual equipment heat. To monitor this increased capacity for trapping waste heat, Arctic enabled its spa packs to take in internal cabinet temperature data and to activate the innovative RossExhaust™ system to balance the cabinet temperature when required.

Lowest Running Costs

What does this mean for the spa owner though? Residual heat from the equipment, primarily the High Flow Energy Efficient motors, is allowed to penetrate through the fiberglass shell. This maintains spa water temperature and eliminates many of the heater cycles that other designs, particularly foam-filled insulated designs have to run. Fewer heater cycles mean a lower power bill each and every month.

True Freeze Protection

One last benefit of the FreeHeat design that we hope you never need is the ability of the spa water’s heat to keep the cabinet from freezing in a power outage situation. Without any insulation between the water and the cabinet, heat energy transfer can work in both directions. In Arctic's testing, and from anecdotal evidence, you have about 5 days, at -4º Fahrenheit before freezing occurs within the cabinet and adding an alternate heat source (space heater, trouble light) can prolong this grace period indefinitely. Nice to have some margin for error, isn’t it?
