FAQ
How does the Thermo-Pond maintain a hole in the ice?
The Thermo-Pond uses a low-wattage heater that activates only when the temperature drops below a certain point, creating and maintaining a small hole in the ice to allow oxygen and water circulation.
Is the de-icer safe for fish?
Yes, the Thermo-Pond is completely safe for fish when used with a pond liner or plastic pond. It maintains a hole in the ice without exposing fish to harmful heat or water changes.
Can it be used in all types of ponds?
It is designed for use in backyard ponds up to 1000 gallons and works best with plastic or liner ponds. It floats on top of the water and is not recommended for deep or unlined natural water bodies.

Installed it last winter and it worked perfectly. The ice stayed broken open even during a harsh freeze. It uses very little power and has been saving me money on electricity. My fish are safe and the pond looks healthy all year.

After switching from a high-wattage heater, I’ve saved over $30 a month. It’s simple to set up and just floats on the surface. No issues with overheating or noise. Great value for the price.
Rose Cameron –
Works well for my 800-gallon pond. The hole stays open and fish seem active. It’s quiet and doesn’t require any maintenance. A little more expensive upfront, but pays for itself quickly.

I’ve used it for three winters now. It’s reliable, energy efficient, and keeps the pond open without any problems. My goldfish are happy and the water doesn’t freeze solid.
