Saving You Money with Efficient Heating
Exclusive 5.5 kW XL Heat Exchanger™
The 5.5 kW XL Heat Exchanger™ is the most dependable, longest lasting heater in the industry. From the moment water enters the heating chamber, warmth is immediately transferred from the XL Heat Exchanger™ patented design. Instead of immersing heating coils in the spa water, the heating element is coiled around a stainless tube that never comes into contact with water and prevents turbulence and chemical corrosion.
Additionally, the oversized surface area of the heating chamber means more water can be heated faster than heating chambers of standard heaters. Lastly, our high-density full foam insulation drives heat directly into the spa water instead of dispersing the heat into the air, which reduces operating costs and increases efficiency.

Backed by a Cal Spas warranty, this advanced 5.5 kW heater is designed to perform. Developed with your comfort in mind, the WhisperHot™ 5.5 kW Heater runs whisper-quiet so all you hear are sighs of ultimate relaxation.
