About this heater

The In.Xe Spa Control 1.0/4.0KW Flow Thru Heater (0602-221063-299) is a genuine Gecko Alliance heater assembly designed for spas equipped with IN.XE control systems. This OEM replacement heater handles both 1.0kW and 4.0kW heating capacities and integrates seamlessly with Pump1 and Pump2 (single speed) configurations. The flow-through design ensures efficient heat transfer while protecting your spa's heating elements from damage caused by low flow conditions.

Built to Gecko's exacting standards, this heater resolves common HH (high limit) and OH (overheat) error codes that plague aging spa systems. At Bubbles Supply, we guarantee an exact fit for your spa's heating requirements, with same-day shipping and a full 1-year warranty on all Gecko Alliance parts. Our technical team verifies compatibility to ensure trouble-free operation. Verify your existing part number and control system model before installation to ensure proper fitment with your spa's electrical and plumbing connections.
