Pond Heaters and De-icers

Here's how it works:

When you plug in your pond deicer or stock tank heater, it constantly uses electricity while monitoring the pond water temperature. The deicer doesn't actually go into use until the air temperature reaches 35°F.

That's where the TCO comes into play - The TCO keeps any power from going to the heater until the air temperature drops to 35°F.
It turns on power at 35°F and turns power off at 37°F. Simply plug the TCO into an outdoor outlet and plug your deicer or heater into the TCO.

The TCO can save A LOT of $$$ this winter!

Other uses: heated gutter cables, thermal bowls, heated pet beds


Safely connect outdoor heated accessories in rain or snow!

The revolutionary LOCKNDRY is the only detachable power supply cord approved by Underwriters Laboratories for use with heated buckets, heated pet bowls, heated bird baths, deicers, etc.. Provides a water-resistant seal while keeping the connection firmly secured. The specially designed plug on the LOCKNDRY cord fits any standard outlet, but when mated with the LOCKNDRY compatible power cord, the large black nut pulls the plug tight against the gasket to form a water-resistant seal. The red nut the locks everything in place and prevents cord separation. The LOCKNDRY is great as an all-purpose extension cord too!

Pond Deicer PTD15

by Allied Precision

The PDT15 1500W, 2 in 1 pond de-icer from API incorporates multiple temperature sensors to monitor water temperature as well as protect against over-temperature conditions. Traditional de-icers use one sensor to monitor both water and heater temperatures. By requiring one sensor to do double duty, the water may be heated more than necessary. With the use of multiple sensors, the PDT15 improves temperature control while keeping a space completely ice free to allow gas escape.

The sturdy, finned aluminum base spreads the heat out to make the heater cooler to the touch while putting the maximum amount of heat into the water. this heater can be safely used in smaller, plastic ponds.

The PTD15 can be converted from a floating to a sinking de-icer by simply removing the cover and float assembly and turning the unit upside down to rest on the pond bottom. Sturdy feet support the unit off the pond bottom when operating as a sinking pond de-icer.

  • Easily converts from a floating to a sinking de-icer
  • Durable aluminum base
  • Energy efficient- maintains de-icing without over heating
  • Multiple thermostat control
  • Large, finned base runs cooler than conventional de-icers
  • Safe in plastic ponds
  • 3 year warranty

Finally! A product specifically designed to eliminate toxic gasses from your fish pond without the energy costs and harmful
side effects of other products.

During winter, gasses from decomposing matter build up under the ice and can kill your fish if they are not allowed to escape. While other
products waste energy in heating to maintain a hole in the ice, the revolutionary Pond Breather is designed to freeze into the ice and move water
above the ice layer where gas exchange can then occur.

The Pond Breather works by moving water from the bottom of the pond to above the ice where toxic gasses can escape and oxygenation can occur. Its split chambered gas exchange chamber generates air flow past the water stream to sustain gas exchange at its highest efficiency. The water then returns to the same level of the pond with just enough heat added to replace that lost to the air.
