Exclusive 5.5 kW XL Heat Exchanger™

The 5.5 kW XL Heat Exchanger™ by Cal Spas is the most dependable, longest lasting spa heater in the industry. From the moment water enters the heating chamber, warmth is immediately transferred from the XL Heat Exchanger’s 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 increasing efficiency. Unlike standard spa heaters, Cal Spas backs the XL Heat Exchanger™ with a lifetime warranty.
