HeatLock System
Heatlock Insulation makes sense- Arctic Spas “Perimeter Heatlock” System is designed to minimise heat loss and maximise energy efficiency. Prior to the spa shell being placed into the cabinet during manufacture, high density insulating urethane foam is applied to the floor, cabinet walls, and doors. The shell is then lowered into the cabinet and a layer of foam is applied to the underside of the rim. This creates a sealed “dead air” space.
Unlike most spas, Arctic Spas’ heater and pumps are housed inside this insulated area to maximise energy efficiency, sheild against mechanical noise, and protect equipment from freezing. Incidental or waste heat from the motors and heater is trapped by the insulation and naturally transfers through the spa shell to contribute to heating the water, significantly reducing overall heating costs.
The captured heat also acts as protection against sub-zero temperatures and protects plumbing and equipment from freeze up. Even without power, at temperatures of minus 40c, your spa water will stay above freezing for many days.
The sophisticated engineering of our Heatlock System provides an ideal operating environment for our pump motors. The water vessel (spa shell) acts as a heatsink, pulling heat away from the motor(s) and other equipment. This greatly increases motor life, and virtually eliminates the overheating problems experienced by other spa brands.
