Product Description

The Laguna PowerHeat De-Icer is for ponds whose temperatures are down to 20 degrees Fahrenheit. The De-Icer is equipped with a 15-watt top-mounted heating element that melts snow on contact, keeping the unit free from snowy build-up. The PowerHeat De-Icer is not meant to heat your pond, but only to aid in gas exchange.

Important information

Directions

The Laguna PowerHeat De-Icer provides a critical environmental control tool for ponds where a pet and property owner needs to keep the water from icing over, potentially killing off the fish inside. This product works particularly well for ponds and small bodies of water that are reaching temperatures of 20 degrees Fahrenheit. The Laguna De-Icer utilizes a 15-watt heating element to break down snow as it makes contact. This feature stops the De-Icer from becoming buried in snow itself. In the meantime, the unit can keep function, performing a necessary gas exchange in the water so that fish aren't deprived of their oxygen. A simple, clear LED light provides a quick indication when the unit is operating as designed. Further, the safety features of the device automatically turns the Laguna De-Icer off if there is a problem. This prevents burn out and electrical problems. To recap, the benefits of the Laguna PowerHeat De-Icer helps with the following: The De-Icer continues gas exchange in the pond, helping the fish inside. The safety features on the De-Icer unit prevent it from over-heating or burning out due to a malfuction of some sort. The unit protects itself with a built in heating element that makes it impossible for snow to build on up on the unit. The features of the unit prevent icing over near the element as it sits in a pond.

New England pond never froze!
5 Stars
New England pond never froze!
After three years of losing fish from toxic chemicals and lack of oxygen due to major icing I decided it was time to try a different route. My pond is 6X10 and about 2 feet deep so just shy of 1000 gallons. I timed my purchase because we were expecting about a week straight of temperatures below freezing. The pond did freeze over the night after I installed the heater but the water was already at 33 degrees. I was delighted to see a hole around the filter the next day after installing it. I was even more delighted to see the ice continue to retract over the days afterward. Even though my neighbor's pond froze solid my pond never did. I have been able to see my fish all winter to make sure they're doing well. We had 20”; of snow fall last week. Even though the snow quickly covered the pond, this heater actually melted all of the snow in just 24 hours. I was under the impression that this was supposed to keep just a hole in the ice. Maybe it is just strong enough to keep a 6X10 (1000 gallon or less) pond above freezing in a typical southern New England winter. Either way I'm very happy. I hope it lasts!May, 2019 Update:Three years of super performance! I was amazed that my pond never froze in January 2018 when we had over two weeks of temperatures that never broke 32. Nights were typically down to below 0. Want to know a real kicker? I never disconnected my waterfall for the winter of 2017 and 2018! No ice dams. No frozen water whatsoever. And here is a bonus for everyone: leave your heater in your pond right through April. All that awful string algae that would normally grow when the temperatures begin to rise...gone! I had to investigate this more and learned that the heater helps get the temperature of the water high enough to allow the good bacteria to colonize quickly. That means that the algae has nothing to feed on. This spring my water has been crystal clear. I disconnected the heater in early May. I’m buying a second unit as a backup since this thing has been so useful. I’d give it ten stars if I could.
