Compatible containers include bathtubs, plastic bathtubs, inflatable pools, and foot tubs. 2. Rapid heating: Submerge the electric water heater into the container—the heater reaches desired temperature within minutes. The 3000W electric heating element ensures efficient water heating—boiling 5 gallons of water in just minutes. Simply place the heater in water and plug it into a standard power outlet. 3. High performance: We use rigorously tested high-performance heating elements rated for over 10,000 hours of operation, featuring robust construction and advanced technology for superior quality, durability, and reusability. 4. Safe and durable: The electric immersion heater uses copper wiring for efficient power transmission. The ABS housing is combined with stainless steel components to prevent rust and minimize direct contact with the heating element—enhancing safety during use. 5.

When the preset time elapses, the device automatically powers off and emits an audible alert—helping prevent accidents caused by forgetfulness. No need to monitor the heater during operation, making it safer and more convenient. Simple operation: Place the heater at the recommended water level (marked by a safety-level indicator line). Plug into a grounded outlet. Check the power indicator light to confirm the unit is on. The portable heater begins operating immediately. Warning: Do not submerge the power cord or handle in water.
