What Is a Pond De-Icer?
A pond is a beautiful addition to any outdoor space, but harsh winter conditions can affect its functionality as the pond freezes over. A frozen pond, or even a layer of thin ice, is a detriment to your property, as it can hurt your fish and your pond’s ecosystem.
A pond de-icer is a specialized device designed to keep a portion of your pond ice-free during winter.
Unlike pond heaters, which warm the entire water body, de-icers focus on maintaining a small opening in the ice to allow gas exchange as the water warms slightly in that area.
This process is crucial for preventing harmful gases from building up under the ice, which could lead to fish deaths and ecosystem imbalances.
De-icers come in different types, with floating and submersible models being the most common.
Floating de-icers rest on the pond’s surface, creating an opening in the ice above them. Submersible models, on the other hand, sit just below the water's surface, gently warming the surrounding area.
Both types are effective, and the best choice depends on the size and depth of your pond. Be sure your pond liners can withstand prolonged exposure to heat and cold.
Our Top-Selling Pond De-Icers
At Pond Haven, we offer a range of deicer models to suit different pond sizes and cold weather conditions. Each unit is designed to support a healthier environment in your pond while delivering reliable winter performance.
Below are some of our best-selling models.
1. Kasco De-Icer
The Kasco De-Icer suspends just below the surface and pushes warm bottom water upward. This helps melt snow and ice while maintaining a small hole in the middle of your pond.
It comes with a high-strength power cord and is built from durable, high-temperature PPS polymer for long-lasting performance.
2. Scott Aerator Floating De-Icer
Built for large pond water surfaces, the Scott Aerator Floating De-Icer works by pulling warmer pond water from below so that your pond does not become completely frozen. It features a stainless steel motor running at 3450 RPM, moving up to 400 gallons per minute.
3. Scott Aerator Dock Mount Pond De-Icer
Designed for secure attachment, the Scott Aerator Dock Mount De-Icer mounts directly to a dock or pilings.
Like its floating counterpart, it moves 400 gallons per minute and operates at 3450 RPM to circulate warmer water temperature.
4. Bearon Aquatics Ice Eater
The Bearon Aquatics Ice Eater is built for boats, docks, and piers. It effectively prevents ice formation by drawing warmer water from below. Known for its energy efficiency and reliability, it is a trusted solution for protecting watercraft and structures in freezing conditions.

Frequently Asked Questions (FAQs)
Do Pond De-Icers Really Work?
Yes, pond de-icers work by maintaining a small hole open in the ice. This allows oxygen in and harmful gases out, preventing winter fish kills and keeping your ecosystem balanced.
While a pond heater raises the water temperature of the entire pond, a de-icer offers a more energy-efficient way to keep gas exchange functioning during the coldest months.
Can a Pond De-Icer Harm Fish?
No. A thermostat-controlled de-icer with a gentle heating element is safe. It does not overheat the water or disrupt fish behavior, and helps improve fish survival during winter.
How Long Should a Pond De-Icer Run?
If your unit has a built-in thermostat, it only runs when needed. These smart features help conserve energy while protecting your pond automatically throughout the cold months.
