Balboa 4.0kW Heater for the Island Spas St. Kitts 120V (2024 & Older)

The genuine Balboa 4.0kW flo-thru heater assembly (incoloy element) for the Island Spas St. Kitts 120V model, 2024 and older. This is the current part — it directly replaces the earlier Artesian heater OP24-0669-08 that originally shipped in these spas.

Before you order: “no heat” is not always the heater — dirty filters, flow problems, and sensors mimic heater failure on 120V spas especially. If you’re unsure, send us a photo of your spa pack label and we’ll confirm the correct heater before it ships.
