3500W Electric Water Heater Stainless Steel Automatic Immersion Heater 220V. This immersion heater is designed for quickly and safely heating water in various containers such as plastic barrels, bath tubs, swimming pools, fish tanks, buckets, and other water-filled containers. To operate, place the heater into the water with a minimum water depth of 25 to 30 cm to ensure the heating element is fully submerged. The unit will naturally float on the surface; adjust the power cord to position the heater correctly. Ensure the metal heating tube remains completely submerged during use to prevent damage. For inflatable pools or similar containers, consider placing a non-conductive material like ceramic under the heating pipe to avoid direct contact with the container surface. Fill the container with water, insert the heater, and plug in the power supply. Once the indicator light is on and small bubbles appear around the heating element, the heating process begins. For large volumes of water, unplug the unit halfway through heating to check the temperature. When the desired temperature is reached, unplug the power supply and wait 20 seconds before removing the heater. Do not use the water while the heater is plugged in. The human body must not come into contact with water during the heating process. Always unplug the device before touching the water. The stainless steel heating element must be fully submerged at all times during operation.
