Pond Heater
Superior floating pond heater designed to keep an open area on the pond surface which is essential for keeping fish and living organisms alive in the winter under ice and snow.  This hole will allow noxious gases to escape from the pond.  Automatic shutoff prevents overheating and saves energy costs.  The unit will turn on as the water becomes frozen and if the temperature rises will shut off.  Has a unique red light that is highly visible to indicate if the unit is on or off.  No guessing as in other pond style heaters.    Also, has a hook that can be used to attach a line to the bottom if desired.  Also, the hook can be used to attach the aerator device which provides aeration of the water during winter.
