The Gecko AEware HEAT.WAV 3kW Heater Tube (9920‑101458) is a premium flow‑through stainless‑steel heater assembly designed specifically for IN.YE, IN.XE, and other compatible Gecko spa control systems. Engineered for reliability and efficient water heating, this 3.0kW heater includes integrated safety systems and durable components, making it one of the most trusted heater replacements on the market.

Built with an Incoloy® heating element, the heater resists corrosion and delivers consistent heating performance under continuous spa operation. It incorporates integrated flow and temperature sensors (no mechanical pressure switch), enabling advanced in.flo dry‑fire protection to prevent damage when water flow is insufficient.
