3500W Electric Water Heater Stainless Steel Automatic Immersion Heater 220V Features: Suitable for plastic barrels, bath barrels, bathtubs, swimming pools, fish tanks, barrels, buckets, and other water-filled containers. Submerge the heater into water, ensuring the water level is sufficient to allow the heater to remain fully submerged. Maintain a water depth of more than 25 to 30 cm to ensure proper operation. The device 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—slight tilting is acceptable for use. For inflatable pools, bathtubs, or containers made of sensitive materials, place a ceramic base under the heating tube to prevent direct contact and potential damage. Fill the container with water, insert the heater, and plug in the power. Wait for the indicator light to illuminate and observe 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. Once the desired temperature is reached, unplug the power, wait 20 seconds, then remove the heater before use.
