Atlantic’s Pond De-Icer maintains a small area free of ice, allowing oxygen in and toxic gases like carbon dioxide and methane out of pond water in the winter. Atlantic’s Pond De-Icer saves energy by cycling on and off, maintaining an internal temperature of 200˚ under the worst conditions. It’s constructed of high strength and high temperature PPS polymer for maximum durability. The internal thermostat turns the heater on just above freezing and off as the water warms for fully automatic operation. An indicator light shines blue to show the De-Icer is in standby mode when plugged in with water temperatures above freezing. The indicator light shines green to show the water temperature is below freezing and the De-Icer is in operation. This efficient heating element only draws 300 watts when needed to keep a small area free of ice and operating costs low. The De-Icer has a 20’ cord, dimensions of 8”W x 4”H and a 1-year warranty.
