1800W Immersion Water Heater for pool & Hot Tub – Portable Fully Submersible Electric Heater with Wifi Timer & Temp Control for Inflatable Pool, Above Ground Pool, Spa, bucket & Bathtub

Smart Temperature Regulation: The immersion pool heater includes built-in thermal control to prevent overheating or dry burning. It automatically shuts off at approximately 60°C (140°F) with a tolerance of ±5°C and restarts when the water cools to 25°C (77°F), ensuring safety and energy savings.
WiFi Timer Control for Safety and Efficiency: This smart WiFi timer allows precise scheduling of heating durations, helping reduce power consumption and improve safety. It features countdown, daily cycle, and on/off settings. Before getting into the water, you can use the timer to switch off the submersible pool heater—eliminating the need to repeatedly unplug the power cord, which can cause socket loosening or short circuits over time.
Premium Material: Made of seamless 316 stainless steel, this heater is highly durable and resistant to cracking during long-term use. Unlike 304 stainless steel, our 316 stainless steel offers superior corrosion resistance, making it suitable for a wider range of underwater environments.
Fast Heating, Easy to Clean & 100% Waterproof: This immersion pool heater instantly reaches optimal temperature within 1 second—no preheating required—making it ideal for quick water heating in bathtubs, inflatable pools, and above ground pools; the smooth surface of the heating element can be easily restored with a steel scrubber, while the silicone-wrapped power cable and fully waterproof design significantly reduce the risk of electrical leakage.
Anti-Damage Base Design:A silicone gasket lifts the heater slightly off the pool or tub bottom, protecting soft surfaces like inflatable pools from high-temperature damage. This ensures better heat circulation and safer use in containers such as above ground pool heaters or soaker tubs.
Portable & Multi-Scene Application: This compact and lightweight portable electric pool heater stands out for its versatility, making it easy to carry and use both indoors and outdoors to heat liquids in various environments—including as a hot tub heater, inflatable pool heater, baptismal pool heater, above ground pool heater, submersible pool heater, pond water heater, aquarium heater, livestock trough heater, or bucket heater.
