Features: 1. Versatile & Safe Heating: Quickly and safely heats water in plastic barrels, bathtubs, inflatable pools, fish tanks, buckets, and various other water-filled containers. Perfect for both household and light industrial applications. 2. Automatic Float & Adjustable Suspension: The heater features an automatic float design. Once placed in water, it floats on the surface. You can easily adjust its suspension depth by moving the power cord to position it perfectly. 3. Essential Safety Operation: For safe operation, the entire metal heating tube MUST be completely submerged in water (minimum water depth of 25-30 cm is required). Never use it if the water level is too low. Always unplug the power and wait 20 seconds before removing the heater from the water. 4. Efficient 3500W Rapid Heating: Constructed with stainless steel and PP plastic, this 3500W immersion heater provides fast, efficient heating. You'll see small bubbles around the heat tube when it's actively working. 5. Added Safety for Delicate Surfaces: When using in inflatable pools or bathtubs made of sensitive materials, place a ceramic tile or heat-resistant pad under the heating tube to prevent direct contact and ensure extra safety. Product Details: This 3500W stainless steel immersion heater is designed for quick, reliable water heating. Its automatic float mechanism allows for easy placement and adjustment in deep water. Remember, safety first: the metal tube must always be fully underwater during use. It's ideal for heating large volumes of water in bathtubs, barrels, buckets, or inflatable pools. Simply plug it in, ensure it's fully submerged, and it will start heating efficiently. Always disconnect power and wait before handling.
