INYE Gecko 4kW Heater

The INYE Gecko 4 kW Heater is the replacement heater assembly for Gecko-built Arctic Spas equipment packs — the INYE-3, INYE-5, and INYE-6 packs used in Classic and Core Series spas, and it also appears on the 2020+ Custom Series (Eco pack) factory parts list. The same heater is used for North American and European spas. When to replace it: The spa won't reach set temperature, the breaker trips when the heater kicks in, or the topside shows heater-related fault codes. Rule out the cheap stuff first — a dirty filter, low water level, or an airlock mimics heater failure. If flow is good and faults persist, the heater element is the usual culprit. Will this fit my spa? Yes, on Arctic Spas with a Gecko pack running a 4 kW heater (Classic and Core Series, plus Eco-pack Custom Series). Not sure which pack you have? Send us a photo of the pack label or visit one of our three Ontario showrooms. Installing it: A heater swap means opening the equipment pack and breaking plumbing unions — shut power off at the breaker and expect some water. If that's not your comfort zone, book a service visit and we'll handle it.
