Dock Deicers, also known as Ice Eaters and Dock Bubblers, are designed to prevent and remove ice by providing a continuous flow of warmer water to the surface. Marine deicers are ideal for boat docks, piers, marinas, ponds and duck hunting, by providing an ice-free zone in a targeted area. A wonderful ecological benefit is that dock deicers keep open, non-frozen areas of water which absorb oxygen and help to sustain fish and other aquatic species.

Do you think these are only for use in the winter? Think again! De-icers, ice eaters or dock bubblers provide year-round benefits such as helping to eliminate stagnant water areas and the foul odors and floating plant growth that accompanies them. Save time, money and effort in caring for your boat dock, pier or marina by using the benefits of a dock deicer or ice eater.

Why Do I Need a Deicer?

Without a deicer, your dock, boat, slip, or marina are vulnerable to severe damage from ice formation and expansion. Simply put, a de-icer or ice eater is your best insurance policy against costly and time-consuming repairs. Deicers" and "ice eaters" are designed to prevent and remove ice by providing a continuous flow of warmer water to the surface. A propeller, driven by a small but powerful motor, agitates and draws warmer bottom water up to the colder water on the surface. The resulting water movement and temperature differential not only prevent ice from forming but can help melt existing ice. It's a simple concept that is extremely effective – and important!

Don't wait for temperatures to drop – protect your investment today.

How Deicers Work

Step 1:

Water near the bottom is heated by the earth.

Step 2:

This water is drawn up to the surface by the de-icer's propeller.

Step 3:

The warmer water and constant motion prevents ice from forming.

Step 4:

An area of clearance is created around the boat or dock.

Deicer Applications & Benefits

Boats, Docks, Piers and Marinas

Deicers prevent or eliminate ice formation, creating an ice-free area around your boat, slip, dock, or pier to prevent damage from ice jacking and expansion during the cold winter months.

Deicers can also protect fish and other aquatic species in your marina during the winter by creating ice-free areas for oxygen to enter into the water.

Duck Hunting

A de-icer mounted on a frame specifically designed for duck ponds will quickly clear any ice and prevent its return.

By properly adjusting the deicer, you can create water movement for realistic, life-like decoy movement to attract more waterfowl to your favorite hunting spot.

Improve Water Quality

The aeration provided by a deicer can reduce foul odors in stagnant water, encourage natural decomposition of organic matter and pollutants, and improve the overall health of fish and other organisms. De-icers can also direct water flow so debris and nuisance vegetation are funneled to one area, making trash removal simple.

Winterkill Prevention

Heavy snow and ice limit the amount of light penetration in your pond causing plants to die, which results in decreased oxygen levels. Without oxygen, your fish will also die.

By upswelling warm, bottom water to the surface, a deicer can create an open water area in your pond to maintain safe oxygen levels and prevent a winterkill situation.

5 Things to Consider When Buying a Deicer

1. Location and Size

Geographic location and the size of the area to be cleared are critical factors in determining your deicer needs. The lower the temperatures fall over a longer period of time, the less area a single de-icer will be able to clear. So regions with typically long and extremely cold winters, will generally require a deicer with more horsepower. Factor in the size of the area to be cleared, and you may find that multiple deicers are necessary.

See table of area cleared by Temperature range (Circular & Elliptical)

2. Water Type

Temperature varies among different types of water. For instance, the more salt in the water, the lower the freezing point. So fewer units may be needed in sea water or brackish water applications than in fresh water. We suggest a quick online search to determine the average high and low winter temperatures for the specific body of water in which you wish to install a deicer.

3. Water Depth

The deeper the water, the more sub-surface warm water will be available to de-ice the area. To achieve maximum performance and successful de-icing efforts, water should typically be at least 4'-6' deep for vertical installation, and slightly shallower for angled operation. For colder climates, consider installing your deicer in water that is at least 6'-8' deep. In all cases, the deicer should be at least one foot off the bottom to prevent clogging from debris.

See De-Icer Diagram: Mount your de-icer to account for high and low tide.

4. Power Type and Source

Most deicers and ice eaters are available in either 115V or 230V. Choose a model with the same voltage as your outlet. Whichever you choose, the amount of electricity used will be the same if operated similarly. It's also important to order a de-icer or ice eater with a power cord that is long enough to reach your deicer directly from the outlet without need for an extension cord. Extension cords can result in reduced efficiency of your deicer and may damage the unit.

5. Obstructions

Objects in the water (i.e. boat hulls, dock floats, pilings, etc.) can obstruct, restrict, or re-route the warm water flow created by a deicer, limiting the effectiveness of the unit. The more objects in the area, the greater the potential for obstruction. In some cases, you may need multiple de-icers to ensure continuous water movement in the area you’re trying to keep clear of ice. In all cases, the units will need to be mounted in the proper location and positioned appropriately for maximum performance.

Mounting Your Deicer

Circular or Elliptical De-icing Patterns

Deicers can be mounted to clear various diameters and either a circular or oval shaped area.

To clear ice in a circular pattern, mount your de-icer vertically.
To clear ice in an elliptical pattern, mount your de-icer at an angle.
See image above for De-icer angles and clearing diameter

Deicer Mounting Tips

Mount your deicer 3 to 5 feet below the water surface and at least 1 foot above the floor of the water. If too close to the floor, debris can be pulled in to the unit, damaging the motor and/or propeller.
Keep deicer submerged during use at all times. If operated in open air, it will quickly overheat and destroy the motor.
For areas with varying water levels, mount de-icer to adjust with the water level, maintaining proper depth below the surface (3' to 5') and height above the bottom (1' minimum).
For shallow water, make sure the deicer is not in a water zone that will freeze solid. If ice reaches the bottom, it will choke off the water supply to the deicer, causing serious damage to the motor.
Always use a Ground Fault Interrupter (GFI) power source and check the GFI on a regular basis. A GFI is an outlet that senses current flow problems and automatically shuts off in those instances to maintain safe conditions.

Deicer Maintenance Tips

While deicers require little maintenance, it is important to inspect your Kasco deicer or Power House Ice Eater on a regular basis to ensure it continues operating at peak performance. These maintenance tips are for general informational purposes only, and are not brand specific. You should always consult your owner’s manual and follow the manufacturer’s recommendations for your specific brand and model.

✔ While your deicer is operating during the winter months, you should observe it on a regular basis (daily, if possible) to ensure it is operating properly. If there is a decrease or variation in performance, disconnect the unit from its power source, remove any debris that may have clogged the system or wrapped around the shaft of the motor (i.e. plastic bags, fishing line, etc.), and inspect the propeller for damage.

✔ The RCD (Residual Current Device) or GFCI (ground fault circuit interrupter) will alert you to electrical leaks in your deicer. Test the RCD or GFCI upon installation and reinstallation, as well as monthly to ensure proper operation. If you have repeat, consistent trips on your ground fault, disconnect your de-icer from the power source, remove it from the water, and inspect the unit and power cord for visible damage. Contact the manufacturer for further instructions or order replacement parts online from SavvyBoater.

✔ Inspect the zinc anode every 2-3 months for deterioration and/or corrosion, and replace it if reduced to half its original size or if it turns white. Since the zinc anode protects the deicer from corrosion and electrolysis, failure to operate the unit with zinc could result in metal deterioration and contamination, and may void your warranty.

✔ Remove the deicer or ice eater from the water and clean its exterior with a power washer at least once per year. It is especially important to clean any build up (calcium, algae, etc.) from the stainless steel motor housing, as this can become an insulator that blocks heat transfer (the motor housing dissipates heat into the water).

✔ Deicers and ice eaters should be removed from the water, cleaned, and stored prop side down (upside down) in a cool place during the off season. Storing prop side down will keep the seals lubricated.

✔ Seals can wear out just like brake pads on a car. Replacing the seals and oil every few years can extend the life of your de-icer. Check the manufacturer’s recommendations for the replacement schedule.

✔ Have your unit serviced by the manufacturer or an authorized repair service every three to four years (depending on the manufacturer’s recommendations).
