Description

Low-Power Winter Pond Protection

The K&H Thermo-Pond 3.0 is a 100-watt floating pond de-icer that maintains an opening approximately 12 inches across for winter gas exchange. Its preset thermostat cycles automatically, providing a low-power alternative to traditional high-wattage pond de-icers.

Recommended use: One unit for an outdoor fish pond up to 1,000 gallons and at least 18 inches deep. It maintains one localized opening—it does not heat the entire pond.

  • Uses only 100 watts while actively heating
  • Floating-only design with a 12-inch diameter
  • Preset automatic thermostat
  • Safe for fish, plastic ponds, and pond liners when used as directed
  • 12-foot power cord
  • MET safety listed
  • Cold-weather tested in sub-zero conditions
  • 1-year limited manufacturer's warranty

Is the 100W Model Right for My Pond?

Choose the Thermo-Pond 3.0 when you need an energy-efficient, floating de-icer to maintain a single gas-exchange opening. Your pond must be at least 18 inches deep.

For a shallower pond, a submersible installation, or more output in severe cold, choose a Perfect Climate Deluxe pond de-icer and select the wattage by pond volume and climate zone.

Installation and Safety

  • Use only in a pond at least 18 inches deep.
  • Place the unit on the water before plugging it in, and keep the heating element submerged.
  • Connect directly to a grounded, GFCI-protected outlet. Do not use an extension cord.
  • Keep the unit within arm's reach of shore and remove snow or ice from its top.
  • For ice 1–2 inches thick, place the unit on the ice and let it melt through. For thicker ice, use an ice auger—never chop the ice.
  • Unplug the unit before removing it from the pond.
  • Read the official K&H instruction manual before installation.

Frequently Asked Questions

What does the Thermo-Pond 3.0 do?

It floats on the pond surface and maintains an opening approximately 12 inches across so gases can escape from beneath winter ice.

Is a 100-watt pond de-icer enough?

It can be when the goal is to maintain one localized opening rather than heat the entire pond. K&H recommends one unit for ponds up to 1,000 gallons and at least 18 inches deep.

Will it heat my entire pond?

No. It maintains an opening about 12 inches across for gas exchange. It does not warm the entire pond.

Is it safe for fish and pond liners?

Yes. It is designed for fish ponds and is safe for fish, plastic ponds, and pond liners when installed and operated according to the instructions.

Can the Thermo-Pond 3.0 be submerged?

No. This is a floating-only model. Choose a Perfect Climate Deluxe model if you need floating or submersible installation.

When does the thermostat turn on?

The preset thermostat cycles automatically to keep the water around the unit just above freezing. There is no temperature adjustment or on/off switch.

How much electricity does it use?

While heating, the 100W unit uses 0.1 kWh per hour, or 2.4 kWh over 24 hours of continuous operation. Actual use is normally lower because the thermostat cycles the heating element.

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

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