Automatic Winter Protection for Fish Ponds

The K&H Thermo-Pond Perfect Climate Deluxe Pond De-Icer maintains an opening in winter pond ice so trapped gases can escape. Choose the 250W, 750W, or 1500W model according to your pond volume and climate zone.

Good to know: This product is a pond de-icer, not a whole-pond heater. It keeps water just above freezing around the unit to support gas exchange rather than warming the entire pond.

Available in 250W, 750W, and 1500W sizes
Works as a floating or submersible de-icer
Preset thermostat cycles automatically
Safe for fish, plastic ponds, and pond liners when used as directed
12-foot power cord
MET safety listed
110/120V electrical operation
2-year limited manufacturer's warranty

Which Wattage Do I Need?

Use both pond volume and climate zone. Colder locations require more wattage for the same pond size, so choosing by gallons alone can lead to an undersized or unnecessarily large de-icer.

Climate Zone Average annual low	0–100 gal.	100–400 gal.	400–750 gal.	750–1,000 gal.	1,000–1,200 gal.
Zone 3 −40°F to −30°F	250W	750W	750W	1500W	1500W
Zone 4 −30°F to −20°F	250W	750W	1500W	1500W	1500W
Zone 5 −20°F to −10°F	250W	250W	750W	750W	1500W
Zone 6 −10°F to 0°F	250W	250W	250W	750W	750W
Zone 7 0°F to 10°F	250W	250W	250W	250W	750W
Zone 8 10°F to 20°F	250W	250W	250W	250W	750W

Sizing data follows K&H's published chart for zones 3–8. For ponds over 1,200 gallons, locations outside these zones, or ponds with heavy fish and organic loads, contact Blue Thumb for help selecting multiple units.

Floating or Submersible Setup

Floating Use

Leave the factory-installed float ring attached. The unit sits at the surface and maintains an opening through the ice.

Submersible Use

Unscrew and remove the float ring, then position the unit beneath the water according to the instruction manual.

Installation and Safety Essentials

Place the unit in water before plugging it in, and keep the heating element completely submerged during operation.
Connect directly to a properly grounded, GFCI-protected 110/120V outlet. Do not use an extension cord.
Remove leaves and other organic debris before freeze-up.
Unplug and cool the unit before removing mineral buildup from the heating element.
Never walk onto unsafe ice or chop through pond ice; shock waves can injure fish.
For an already frozen pond, follow the approved method in the official K&H instruction manual.

Frequently Asked Questions

What does a pond de-icer do?

It maintains an opening in winter pond ice so gases can move between the water and air. This helps prevent gases from becoming trapped beneath a completely frozen surface.

Will it heat my entire pond?

No. It keeps water just above freezing near the unit to preserve an opening in the ice. It is not designed to warm the entire pond.

Which wattage should I choose?

Match your pond volume to your climate zone in the sizing chart. Colder climates require more wattage for the same pond size, so do not choose by gallons alone.

Is it safe for koi, goldfish, plastic ponds, and pond liners?

Yes. K&H designed the unit for fish ponds and states that it will not harm fish, plastic ponds, or pond liners when installed, maintained, and operated according to the instructions.

Can it be used floating or submerged?

Yes. Leave the float ring attached for floating use, or unscrew and remove it for submersible use. The heating element must remain completely underwater during operation.

Does it have an adjustable thermostat or on/off switch?

No. The internal thermostat is preset and cycles automatically to keep water around the unit just above freezing. The unit is powered whenever it is plugged in.

How long is the cord, and can I use an extension cord?

The attached cord is 12 feet long. The manufacturer instructs users not to operate this MET-listed product with an extension cord. Use a properly grounded, GFCI-protected outlet.

How much electricity does the 750W model use?

While actively heating, the 750W model draws 0.75 kilowatt-hour per hour, or 18 kWh over 24 hours of continuous heating. Actual use is normally lower because the thermostat cycles the heating element.

Why is foam forming around the de-icer?

A temperature difference between the water inside and outside the float ring can cause dissolved gases to create harmless foam. Investigate foam accompanied by an unusual odor, poor water conditions, or fish distress.

How should I clean and maintain it?

Unplug the unit and allow it to cool before cleaning. Remove mineral deposits from the heating element and keep the protective cage free of debris. Mineral buildup can reduce performance or cause the GFCI to trip.
