3500W Electric Water Heater Stainless Steel Automatic Immersion Heater 220V 3500W. Suitable for plastic barrels, bath barrels, bathtubs, swimming pools, fish tanks, barrels, buckets, and other water-filled containers. Place the heater into the water, ensuring the water level keeps the heater suspended. Water depth should be more than 25 to 30 cm. The product will naturally float on the surface; adjust the power cord to position the heater correctly. If the water level is below 25 cm, ensure the heating element is fully submerged. The heater can be slightly tilted for use if necessary. For inflatable pools, bathtubs, or other flexible material containers, place a ceramic tile under the heating tube to prevent direct contact with the container base for safety. Fill the container with water, insert the heater, and plug in the power. Wait for the indicator light to turn on and observe small bubbles forming around the heating element, indicating heating has started. For large volumes of water, unplug the unit halfway through heating to check water temperature. When the desired temperature is reached, unplug the power, wait 20 seconds, then remove the heater before use. Type: Electric Water Heater. Model Number: Electric Water Heaters. Power: 3500W.
