Pond De-Icers

Picking the right pond de-icer

The pond de-icer is a device used to prevent the accumulation of ice in your pond during the winter months.

Do I Really Need a Pond De-icer?

In short, Yes! Have you ever experienced a pond developing a layer of ice? The best way to manage this ice buildup is through the use of pond de-icers. Specifically, it's used to melt a small hole in the ice which then provides an escape for toxic gases to leave and oxygen to enter the pond. Pond deicers will prevent winter-kill from occurring altogether.  

There are many different types of pond de-icers available on the market today that can be selected based on size and desired features (i.e., solar). If you have pond with a large surface area, then the pond de-icer that you choose will be larger than one for a pond with minimal surface area.

This applies to other characteristics of pond deicers as well, such as solar, thermal or gas.

Total pond surface area should be considered when pond shopping and selecting a pond de-icer.

Selecting the Right Pond De-Icer for Your Pond

Now that pond size is factored in, it's time to choose a pond de-icer. There are many different types of pond de-icers available on the market today that can be selected based on size and desired features (i.e., solar or thermal).

If you have pond with a large surface area, then the pond de-icer that you choose will be larger than one for pond with minimal surface area. This applies to other characteristics of pond deicers as well, such as solar, thermal or gas.

A pond de-icer employing solar technology has a reel containing black tubing that absorbs energy from the sun and transfers it to a pond liner, pond wall or pond floor. Depending on the pond's size, depth and material used in construction, an average solar pond de-icer will generate enough heat from 10 to 30 degrees above ambient temperature.

Solar Pond De-Icers

Solar technology is fairly new when compared to traditional gas equipment but has been proven to be safe and effective pond de-icers.

A pond de-icer employing a propane gas emitter will heat the water in your pond when there's not enough solar or thermal energy available for proper heating.

The temperature of the pond water can reach up to 30 degrees above ambient temperature. In addition, this type of pond de-icer can also emit carbon dioxide to aid in the pond's biological processes.

Now that we've discussed three commonly used pond de-icers, you're probably wondering which one is best for my pond? Pond size is the most important factor when choosing a pond de-icer because it sets them apart from others by size alone. 

For example, if you have only an 1,800-square foot pond, than the pond de-icer you choose will be smaller than that of a pond over 7,000 square feet. If pond size is the same, then there are other pond de-icers available on the market today that employ solar technology, propane gas emitter or through thermo dynamics and can help prevent pond ice from forming.

In addition to pond size, your budget will also have an impact on which one is best for your pond.

Let's compare solar vs gas in regards to price.


On average a solar pond de-icer costs $1 per watt and a gas pond de-icer costs $3 per therm (100 degrees). As you can see, it would cost more money to heat your pond using a gas pond de-icer than solar pond de-icer.

There are many pond dealers that would also be able to offer you more insight on which pond de-icer will better suit your pond's needs, regardless of pond size.

For example, if you live in an area where the temperature drops below freezing every year, then a pond with a large surface area should have a larger pond de-icer installed to ensure it will maintain its heat.

If you don't want to spend the money or time installing a new pond de-icer once winter arrives, then consider installing one before fall hits. This way it'll be available for use as soon as the weather turns cold and freezing temperatures arrive.

As previously stated, solar pond de-icers are relatively new pond equipment and as this pond technology has become more popular many pond dealers have begun to offer solar pond de-icers. You might find yourself asking, "What is a solar pond de-icer?"

As we mentioned previously, the main component of this pond maintenance tool is black tubing that absorbs power from the sun during daylight hours and transfers it to your pond's liner, pond wall or floor. This helps prevent ice from forming in your pond by helping to raise water temperature above freezing levels on average 10 degrees.

Are pond de-icers hard to install? No!

Just about anyone can help install a solar pond de-icer into their pond if they follow proper installation procedures which include having enough room around the perimeter of your pond for supporting structures and wiring.

The pond liner is the most important part of your pond to keep ice-free during the winter months. It's recommended that you have at least 1 foot between the pond water and pond liner. If a solar pond de-icer has been installed properly, it will help prevent pond ice from forming by maintaining an average temperature 10 degrees above freezing.

The decision to install a solar pond de-icer or choose another type of pond equipment should be based on pond size and individual preference.

Additionally, take into account what type of budget you have for purchasing this maintenance tool as well as the time needed to set up this device in your pond before cold weather hits if you haven't already done so.

Today there are many methods available when comes to pond de-icing. Some pond owners choose to purchase pond freeze protectors, while others prefer pond heating coils and others still install large pond solar heaters to keep their pond open all winter long.
