    Dock De-Icers protect your property against dock ice damage. Images here show how.


    What is a Dock De-Icer?

    A dock de-icer is a unit placed in the water during winter mostly by boat owners, to keep the water around their dock from freezing.  Dock de-icers use a motor with a propeller to thrust warmer water from below the surface up to the top. This not only keeps ice from freezing, but will even melt areas that have already frozen over. They are key in keeping the water from freezing around your boat.


    Benefits of Using a De-Icer

    • Protect your Property Damage: They keep the water around your dock and boat from freezing. This will protect your assets from damages and expensive repairs.

    • Saves Time Later: When the nice weather arrives in the Spring and Summer, you want to be out on your dock and boat. What you don't want is to have your dock or boat under repair when you want to be enjoying it.

    • Good for Ponds: In ponds, de-icers are crucial for the health of fish and other pond life in winter. It also protects the pond itself from ice damage. By keeping part of the water ice-free, pond life can survive the cold months better. Duck and waterfowl hunters also use them to keep their ponds open.

    The Dock Bubbler Technique

    This method uses diffused air to stop ice from forming. It works by a massive flow of air bubbles moving warm water from the bottom of a body of water to the top. This flow of warm water keeps ice away. This is also energy-efficient because it uses naturally warm water from below. 

    Here are some easy tips for using it:

    • Place the diffused air manifolds in and around the area that you want protected. 
    • Make sure manifolds are weighted so that they stay in place. You can attach ropes to them so that they can be easily moved.
    • Make sure to follow the manufacturers safety rules.
    • Watch the water to make sure the stays clear of ice. Make changes to the dock bublers position if you need to.



    Selecting the correct and best dock de-icer is important to keep things safe and protect your investments in the winter. Whether you go for the water circulator de-icers or the dock bubbler method, being proactive about dealing with ice is the way to have a stress-free winter on the water.
