Gecko IN.YJ 3.0kW Heater
Official replacement 3.0kW remote Gecko AeWare IN.YJ heater used specifically on hot tubs and spas. Gecko's blue compact AeWare remote heater with built-in temperature and flow sensor used with small Gecko Aeware IN.YJ spa control box.
Usually found on plug and play spas as the 3kw element only draws between 8-8.5 amps, thus keeping a spa running below 13 amps when heating.
