Heatlock Insulation makes sense - Equipment outside of the insulated area can freeze up in a few hours if a power failure occurs in winter conditions. Remember, water that is not moving freezes quickly. The 400 gallons of water in most spas will retain its heat for an extended period of time in the winter. Most of the time, it will last for days before freezing. Now, if you remember physics lessons, heat always travels from hot to cold. You 104 degree Arctic Spa will protect its own equipment automatically by transfering that heat back down through the fibreglass and keeping the equipment area above freezing. You don't have to worry about your investment in winter.

Even at -40°C equipment would be protected from freezing. Each Arctic Spa comes with our Perimeter HeatLock Insulation system, designed to minimize heat loss and to maximize energy efficiency. We apply high density urethane foam to the floor, cabinet walls and the spa rim underside, creating an insulating dead air space.

This form of insulation has proven itself over and over in the harsh climates of Northern Canada. Our sturdy cedar construction, combined with the perimeter insulation, provides an insulated protected air space for efficient performance of the plumbing and electrical equipment. Incidental heat from the motors is directed inward through the shell instead of outward, thereby decreasing heating costs by capturing and transferring this ambient heat to the spa water.

This captured heat acts with the Perimeter HeatLock system to provide a secure protection against freezing in sub-zero temperatures. If power to your spa is interrupted, heat from the spa water slowly transfers to the dead air space, protecting the plumbing and equipment from freeze-up.

The Perimeter HeatLock system allows easy access for servicing and upgrading your spa, or for adding extra jets. It also acts as a sound barrier, so you can enjoy your Arctic Spa without being disturbed by mechanical noise from the pumps and motor.
