De-Icers & Circulators for Marinas, Docks & Waterfront Properties
Ice is the most expensive thing that happens to Canadian waterfront property. Fountain Depot supplies Kasco de-icers, water circulators, dock mounts and thermostat controls that keep water open and moving around docks, boat lifts, boathouses and marina slips through winter — and keep debris, weeds and stagnant water away from the same structures all summer. Every system is sized to your depth, exposure and power before you buy.
What Ice and Stagnant Water Do to Waterfront Property
As ice forms and shifts, it grips pilings and lifts them out of the bottom ("ice jacking"), crushes floating docks, bends boat-lift frames and grinds against hulls left in the water. Spring breakup and moving ice sheets do further damage in exposed locations. Summer brings the opposite problem: still water around slips and shorelines collects floating debris, grows weeds and algae between fingers, and turns stagnant and odorous exactly where people board boats. Both problems have the same fix — moving water.
What We Recommend
Kasco de-icers
A Kasco de-icer draws warmer bottom water upward to maintain an area of open water around the structures you need to protect. Units can float, suspend below the surface, or mount to the dock itself. Browse the full pond and lake de-icer range for all options.
Water circulators for year-round duty
Kasco AquatiClear circulators are the year-round workhorse: directional flow that de-ices in winter and pushes floating debris, weed fragments and stagnant water away from slips and shorelines in summer. The AquatiClear 2400CDM with universal dock mount installs directly on the dock without a float. Already own a Kasco de-icer? A de-icer to AquatiClear conversion kit converts it for clog-resistant circulation duty.
Dock mounts
Purpose-built Kasco dock mounts position de-icers and circulators at the correct angle and depth for your dock configuration, and make seasonal removal straightforward.
Thermostat and timer controls
Running a de-icer 24/7 all winter wastes electricity. Kasco control panels with thermostat and timer functions run the unit only when air temperature actually demands it — the difference shows up directly on the hydro bill, especially at marinas running multiple units.
How to Choose the Right De-Icing Setup
Sizing depends on water depth at the structure (de-icers need enough depth to draw warmer bottom water), exposure (wind-blown points and north-facing shorelines need more capacity than sheltered bays), what you're protecting (a single boat lift needs less coverage than a row of slips), and available power — 120V covers most single-dock installations, while marinas running multiple or larger units should plan around 240V circuits. Mounting choice matters too: floats for open areas, dock mounts where you want directional flow. For marinas and multi-slip layouts, email Info@fountaindepot.com or call 905-752-1226 with a sketch of the dock layout, depths and power locations and we'll lay out unit count and placement. Order before freeze-up — installing into open water is far easier than installing through ice.

Frequently Asked Questions
How does a de-icer protect a dock from ice damage?
A de-icer continuously moves warmer bottom water to the surface, maintaining an area of open water so ice can't form against and grip your dock, pilings or boat lift. Without that grip, ice can't jack pilings or crush floating structures as it expands and shifts.
What size de-icer do I need for my dock or boat lift?
It depends on water depth, how exposed the location is to wind, and how large an area you need open. A sheltered single boat lift needs far less capacity than an exposed dock face or a row of marina slips. Send Fountain Depot your depth, layout and location and we'll size it — oversizing wastes power and undersizing risks the structure.
What's the difference between a de-icer and a bubbler?
A bubbler releases compressed air at the bottom, while a Kasco de-icer uses a submerged motor and propeller to push warm bottom water upward. De-icers are the standard choice for targeted dock and boat-lift protection because the open-water area is directional and controllable.
Should a de-icer run all winter, 24/7?
Not necessarily. A thermostat control panel runs the de-icer only when air temperature requires it, which protects the structure while significantly reducing electricity use compared to continuous operation. Timers are another option for milder regions.
Can the same equipment help in summer?
Yes — a Kasco AquatiClear circulator works year-round: de-icing in winter and pushing floating debris, weeds and stagnant water away from slips, swim areas and shorelines in summer. Existing Kasco de-icers can be converted with an AquatiClear conversion kit.
When should I install my de-icer?
Before freeze-up — in most of Canada that means having equipment on site by October. Installation into open water is straightforward; installing through ice is difficult and hard on equipment. Fountain Depot ships across Canada in roughly 3 to 10 business days, so order ahead of the season.
Does Fountain Depot supply full marinas?
Yes. Fountain Depot supports marina and multi-slip projects with layout advice, unit-count planning, control panels for multiple units, and commercial quotes. We're an authorized Kasco dealer and repair centre, so parts and service support continue after the sale.
