Best De-Icers

With winter comes colder weather, and in many regions, this means ice and snow which can mean lots of costly damage to docks and boats if not properly protected.  A solid freeze puts extreme pressure on docks and boats and damage is often not discovered until it’s too late.  Dock De-Icers help prevent this damage and can end up saving you thousands of dollars in the long run.

Winter ice can also impact duck and waterfowl hunting, in which case a De-Icer helps attract waterfowl by keeping water open and accessible.

Frequently Asked Questions

How Do Pond De-Icers Work?

Pond de-icers pull warmer water from deep below the surface and push it upward. This stops the top layer from freezing, which protects docks and boats. They also warm the water just enough to create a small open area in the ice, without warming your whole pond.

The EasyPro Air De-Icing System does this by sending air through tubes. It comes in different sizes, like the DKSW30 (for docks up to 30 feet) and the DKDW100 (for docks up to 100 feet).

The Scott Aerator Floating De-Icer is a self-contained unit that floats on the surface and stirs the water directly.

Can a Pond De-Icer Save My Fish?

Yes. In winter, ice can trap gases under the surface, which can harm or kill fish. A pond de-icer helps keep a hole open in the ice so gases can escape and oxygen can get in.

Can a Pond De-Icer Help with Ducks?

Yes. Ducks are drawn to open water in the cold. A frozen pond won’t get any activity, but using a pond de-icer or ice eater for duck hunting helps create a landing zone. That open water is key for late-season hunting.

Can Ice Really Damage Gear?

Yes. As ice thickens, it can press hard on docks, blinds, and boat lifts. That pressure can lead to cracks, bending, or worse. Using a pond de-icer now keeps that from happening.

What's the Difference Between a De-Icer and an Aerator?

Both move water, but they’re built for different reasons. A de-icer stops ice from forming by warming a small part of the water. On the other hand, a fountain or aerator’s main job is to add oxygen to the water, which can help fish but may not always stop ice from forming.

Do De-Icers Cost a Lot to Run?

Most de-icers use very little electricity. Some air-based systems cost just a few dollars a month to run. They’re efficient and run all winter without using up your power bill.
