Heatlock

The theory of insulation works the same for spas as it does for houses. House A illustrates the proper method for maximum efficiency and prevented heat loss. Unfortunately most spas are insulated like House B, with most of the insulation in the basement and the heating equipment outside! You wouldn't heat your house like this, so why your spa?

ARCTIC SPAS

Ambient heat from pumps penetrates spa shell & heats water.
In winter this heat returns to the pump area in the event of a power loss, preventing freeze-up.

OTHER SPAS

Some manufacturers place their pumps under a step, or in an insulated area where the waste heat is vented into the atmosphere, thus wasting valuable energy-and money!! This design flaw does not make sense, but many manufacturers would have you believe it's the best method--What do you believe?

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. Even at -40oC, equipment would be protected from freezing.

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.
