Spa Features

Energy Saver System

The spa's mechanical equipment produces warmth as it operates. QCA's insulated cabinet is designed to retain some of that warmth around the shell and plumbing, helping limit heat loss to the surrounding outdoor air.

Conceptual arrows show equipment warmth retained within the cabinet. They do not represent water flow or a measured air-circulation path. Not to scale.

An enclosed thermal space

The insulated walls and floor surround the equipment space, helping retain warmth inside the cabinet. This supports heat retention while the spa's heater continues to regulate the water temperature.

Choose a cover for your climate

For colder climates, QCA recommends a thicker, highly insulating cover. Keep the cover fitted when the spa is not in use to help reduce heat loss.

Heat retention and energy use vary with climate, cover, settings and spa use.
