300 Watt Pond Heater/De-icer

Aquascape stainless steel Pond De-Icer is ideal for keeping a small hole opening the ice during cold winter months, and insures proper gas exchange helping keep fish alive during the winter.

It is important to leave a small hole open at the surface of the pond allowing for necessary gas exchange. In extreme conditions or gardening zones above zone 5 we recommend the deicer be used in conjunction with an Aquascape pond aerator.

In addition... There is a safety built in that cuts power to the thermostat if the temperature reaches about 20C - to save the life of the thermostat if the pond-owner leaves the unit in the pond after the winter, into the spring.

Simply unplug the unit, and plug it back in to reset it if necessary... If a customer was to leave it in the pond all year - they should reset it before each winter.


  • Features:
    • Keeps a small hole in the ice during winter months
    • Helps increase pond oxygen levels
    • Stainless steel construction prevents corrosion and cracking
    • Integrated thermostat saves electricity
    • Built-in LED light indicates when heater is in use (blue light means the unit is on; red light means it is off


A unique feature of this heater is the LED light on the top of the unit.  The LED light will be red when the unit is heating, and blue when the heater is in the off mode and not heating.

Please note:  the thermostat on the de-icer is set to turn off at 70°F or 21°C.  The thermostat is a safety feature and not meant to turn off the heater when ice is not present.

What this means:  
  1. Do not plug your de-icer in until ice has formed on the pond (and hasn't melted during the day).  
  2. If the water temperature is 70°F or 21°C the de-icer will run.  
  3. You may use a timer during winter so that the unit only runs for 12 hours per day.  
  4. At our current hydro rates, you can expect the cost of running the de-icer 24 hours per day to be about $1 a day.
