DE-ICER MANUAL
5
Kasco offers two basic options for
de-icer installation: vertical rope
suspension or dock mounting.
Different de-icing objectives may
require different mounting and
installation approaches.

Placing a de-icer depends on your de-icing objectives. If ice expansion pressure is your concern, you may
find it easier to have an open-water buffer between your dock or structure and the expanding ice pack.
If ice lifting or a combination of lifting/expansion is your concern, you may wish to keep your dock, structure,
or boat area completely free of ice. These objectives are different and may require different installations.
2.
Calculate the Optimal Depth for Your De-icer
Determine the best location(s) to install. A de-icer draws warmer, denser water from the bottom (4O °C /
104 °F is approximately water’s densest point) and circulates it upward to the surface. Around docks and
boats, water is usually fairly shallow, so look for somewhat deeper water to install your de-icer. However, if
your de-icer is installed too deep, the rising warmer water will not effectively spread at the surface, thereby
reducing the de-icing effect.
A good guide is to place the de-icer 4-6 feet deep for vertical installation and slightly shallower for
angled operation, but at least 1 foot off the bottom to prevent clogging from debris. In colder climates,
circulating warmer water is more important than surface circulation, so you may wish to install your
de-icer deeper than the above guidelines. De-icers generally work in shallower water but are less
effective, and due to the constraints of the environment, you may have to settle for a shallower
installation. We recommend that you experiment with more than one possible location for the best
installation results.
