Floating pond de-icer maintains an open air/water interface at water surface. 120W heater for energy efficiency.
Use Instructions:You should place it near the edge of the pond. Begin using it before ice forms. If ice has already formed, place the unit on the ice. It will melt through it. The deicer is thermostatically controlled, so it should not overheat and harm pond liners. This unit uses 120 watts.
