More features

• SMART THERMOSTATIC CONTROL – AUTO ON/OFF: Our pond heater features a built-in intelligent thermostat that automatically activates below 41°F and shuts off above 131°F . It keeps a small ice-free zone for gas exchange while saving up to 50% energy compared to non-thermostatic models.
• STRONG 1000W HEATING PERFORMANCE: This pond heater delivers fast, efficient heating power to keep your pond surface open for oxygen exchange during harsh winters. With stable output and superior heat coverage, it melts ice twice as fast and wide as lower-wattage models — perfect for most ponds and cold climates.
• SAFE FOR FISH & ALL POND TYPES: The fish-friendly floating design melts a small hole to exchange toxic gases for oxygen, eliminating the need to heat the entire pond. Suitable for 50-500 gallons plastic, rubber, or liner ponds and saltwater ponds. The sealed structure prevents electrical leakage and protects your koi and aquatic plants throughout the winter.
• DURABLE & RUST-RESISTANT MATERIAL: Made from durable cast aluminum with an anti-corrosion coating, our de-icer withstands extreme cold and harsh weather. The solid shell ensures even heat distribution and long-term performance without deformation or rust.
• EASY TO USE – PLUG & PLAY: Simply place the heater in your pond and plug it in — no assembly required. Equipped with a long 10ft UL-certified power cord for flexible placement. The indicator light lets you know when the unit is actively heating.
• NOTE: Before use, fully submerge the de-icer to release trapped air so it can float level with about half the unit underwater. The red light turns on only when heating is needed. If it’s off, the water is already above freezing — it doesn’t mean the product stopped working or is broken.
