Shallow Water De-Icing
To de-ice a shallow water area, direct the flow of warmer water from the deeper area into the shallower area. Remember, a De-Icer works because it draws warmer, denser water from the bottom and circulates it upward to the surface, preventing ice formation or melting existing ice. By positioning a de-icer near deep water areas and mounting it to angle back toward the shallow area, you can successfully push the warm water toward the shallow areas and prevent ice formation.
It is often easier to de-ice a boat by installing the de-icer at or near the bow, angled toward the stern. For large boats, it may take multiple units to properly de-ice the area, but following the natural contouring of the boat's hull will provide the most effective results. De-Icers can often be hung from cleats and suspended under the hull. For extremely wide hulls, you may need to suspend units off either side. Depending on the depth, diffusers can also be installed directly under the hull, on the bottom.
Dock & Pier and Shoreline De-Icing
When de-icing a dock or pier, you can place the de-icer at an angle forcing the water back toward the shoreline. If the water flow is directed toward the shore or a retaining wall, it will flair, forming a desirable ”T” shape de-icing pattern. This flair will extend the total area of open water and provide an ample area of open water around the dock or pier. If shoreline de-icing is not desired, vertical installation is best and a curtain can be installed into the water to prevent flow beyond a given point, as desired.
In tidal waters, split the difference in water depth so the De-Icer is in shallow water at low tide and deep water at high tide. Another option is to tie your De-Icer to a boat or floating dock and allow the boat/dock and De-Icer to rise and fall with the tide.
