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, bathtubs, swimming pools, fish tanks, buckets, and similar water-filled containers. To use, place the heater into the water ensuring the heating element is fully submerged. The water level should be at least 25 to 30 cm to allow the heater to remain suspended in the water. The unit 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 pipe is fully submerged and the heater can be slightly tilted for proper operation. For inflatable pools, bathtubs, or other flexible containers, place a ceramic base under the heating pipe to prevent direct contact with the container material for safety. Fill the container with water, place the heater in, and plug in the power. 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 and check the temperature before continuing. When the desired temperature is reached, unplug the power supply and wait 20 seconds before removing the heater from the water. Then the water can be used. Important: The metal heating tube must be completely submerged in water during operation. Never use the heater outside of water or while it is dry. Always unplug the device before touching the water. Do not allow human contact with water during heating. Always disconnect power before removing the heater or using the water. The stainless steel ball portion must remain fully submerged during heating to prevent damage.
