The included Econo-Boost system far exceeds the California Energy Compliance mandate. The Siena spa is sure to please family and friends alike.

QCA Spas Use Quality Components

The Siena’s shell is manufactured with Lucite-Xtra Acrylic and Dura-Bond, a three-layer strengthening process. The maintenance-free DuraFrame spa cabinet is constructed of synthetic wood with reversible panels. If one side of any of the spa panels get damaged over time, you can simply flip them over to make your spa look new again. The DuraFrame’s patented galvanized, powder-coated steel frame support system will provide you with longevity and durability through the life of your spa.

The spa jets are powered by two energy-efficient pumps with an air flow control system, adding air to the jets and increasing their strength for the perfect massage. Spa maintenance is very simple with automatic heating systems, filter cleaning cycles, and even freeze protection.

Top-Side Control

You can easily access the top-side controls from inside or outside of the Siena spa. Balboa’s four-button Soft Touch control panel adjusts the temperature, pump, and light. The Soft Touch control pad also features diagnostic read-outs in the LED display.

QCA Spas Energy Saver System

All QCA Spas feature the Energy Saver System, a frictional heat recovery system. This energy-efficient design allows the recycled heat that is generated by the pumps to be trapped inside the cabinet in order to assist warming the spa’s shell and water from the inside, which saves you money. The spa’s 4KW heater includes self-protection from overheating in all weather conditions, thanks to M-7 technology.
