The K&H Thermo-Pond 3.0 is a unique, patented de-icer that maintains a hole in pond ice for just pennies a day. It's the worldʹs most energy efficient pond heater and works with ponds up to 1000 gallons.

Unlike some other heaters, the Thermo-Pond 3.0 will never burn a pond liner or plastic pond. It floats on top of the water and is thermostatically controlled to never get hot. This allows a pond to ice over naturally while maintaining a hole that facilitates gas exchange for wintering fish.

Small Package, Big Energy Savings

While other high-wattage de-icers can drive electric bills through the roof, the K&H Thermo-Pond 3.0 is easy on your budget. It consumes a mere 100 watts of power and operates for just pennies a day. With the money you'll save compared to running a traditional pond de-icer, the Thermo-Pond 3.0 can pay for itself in a few months.

Thermostatic Temperature Control

Internal thermostats automatically monitor water temperature and turn the floating Thermo-Pond 3.0 on and off as needed to keep the average water temperature just above freezing. Our patented technology ensures that your pond de-icer will only run as often as needed to maintain a 12 inch hole in the ice. In fact, it's thermostatically controlled to never get hot when properly submerged in water. Unlike some other heaters, Thermo-Pond will never burn a pond liner or plastic pond.


This product has been tested and certified by MET Labs to meet their high standards for electrical product safety.

As with any electrical product used in wet locations, please plug the Thermo-Pond 3.0 into a ground fault circuit interrupter (GFCI) outlet

Gas Exchange Keeps Fish Alive

An open hole in pond ice allows proper gas exchange and helps fish survive the winter. The Thermo-Pond 3.0 facilitates this exchange by maintaining a 12 inch hole in pond ice, even in sub-zero weather. Add this K&H pond de-icer to create a healthier environment for your fish this winter.

To ensure that your fish have plenty of livable area, please operate the Thermo-Pond in ponds with a depth of at least 18 inches.

Safe For Fish

Even when they do come in contact with the heating element of a K&H deicer, your fish are quite safe. The heating element will never get hot to the touch as long as it is properly submerged in water. You can actually reach down into the water and put your finger on the heating element and it will not burn you. In the middle of winter when it gets really cold you’ll find your fish huddling around the deicer to keep warm, but the deicer will never harm them.

Already Frozen Ponds

  • If the ice on your pond is more than 2 inches thick, drill a hole with an ice auger and place the Thermo-Pond over the hole. Do not chop through the ice in smaller ponds as the shock waves can damage or kill your fish.
  • If the ice is only 1 or 2 inches thick, place the Thermo-Pond on the ice and it will melt its way through the ice.
  • Try to position your Thermo-Pond within arm’s reach of shore to avoid walking on thin ice.
  • Snow and ice should be removed from the top of your Thermo-Pond.
  • Always keep safety as your number one priority. Never walk on thin ice.
  • Please consult your pond professional on tips for overwintering fish.
