Balboa 4.0kW Titanium Heater for Island Spas
The genuine Balboa 4.0kW flo-thru heater with a titanium element — the direct upgrade for the standard incoloy 4.0kW heater in Island Spas built on Balboa control systems. Titanium resists the corrosion that shortens standard element life, making it the right choice for spas on salt systems or with a history of eaten elements.
Before you order: “no heat” is not always the heater — dirty filters, flow problems, and sensors mimic heater failure. Match your spa pack label. If you’re unsure, send us a photo and we’ll confirm before it ships.
