It keeps the water open. If it's very cold there may only be a hole in the ice under the little dome. During milder temperature times, it keeps my entire little pond clear of ice. You can't feel any warmth if you plug it in and hold it...at least I couldn't. This is my third one -- I love them. I had one go bad when it developed a crack and water got inside and corroded the heating elements. I could hear water in it when I shook it. Don't drop it anytime -- hairline crack will allow water to get inside. BTW -- for some reason, my goldfish hang around it. Maybe there is more oxygen in the slightly warmer water. Anyway...enjoy!

The water around it and looking through the center are not frozen. It thaws just enough water so the unit can still move around a little. The unit kept a hole in the ice all winter in Michigan and that's all you need to let the gasses escape.

The center of the heater is open and there is water. The pond has iced over.

You know it is working when the water is not frozen in the center of the unit.

It melts the ice. Ice youput it out once it is REALLY cold, it will take a while to keep up. You can put a blanket or old rug to help it get started. It will feel very lightly warm to the touch.

If it's working there will be no ice in the center. After a heavy snow you may have to remove the build up in the center. It runs on only 100 watts so it won't get supper hot. You can get a much higher wattage heater at a farm supply store but they cost a lot more to run.

It will keep the ice melted around the de-icer if the temperature is cold enough. It automatically shuts off if it's too warm outside. If you set it on on ice, it will melt right down through the ice, but I put mine in before it froze. Do not chop a hole in the ice while there are fish inside. The percussion will injure the fish.

Good question, because it's difficult to know. Last year I didn't realize mine was not working until it was too late and the pond had frozen solid, locking the heater in. I didn't replace it and this season am using a small pump instead to maintain an open area in my pond's surface. Good luck!

This is used to check that the collar is working. You will see two places on the tool with small metal pieces. Place these on the two metal probes on the collar and press the remote. If you have the tool correctly on the probes and the collar is working, and the remote is working, the tool should light up!! This tells you the remote and collar are working and a current is being passed through the probes when you press the remote.

I started to work immediately. After some time, was a failure. Turned off and then turned on. Started to work. Another piece of advice I can not give. Good luck.

Something is wrong with it. Mine works very well and it stays when I want it to. It's really an amazing product. Sorry yours isn't working, but it might be worth trying again.

I cannot answer your question. I guess if it doesn't work you know that it's occurred!

Yes, you can see it is working. The UVC is invisible, but it also emits just enough visible light, kind of a bluish tint, that you can see it. When batteries are getting low, it gets hard to see, your cue that you need more batteries, or to plug it in.

1. Are the batteries in correctly? 2. Are they within the correct distance from the main light? 3. Place all lights together, turn off your power and see if they work? 4. Call the Company.

Read and follow the instructions on the container. It works, just be patient.

It shows that the power is successfully connected. It goes out but never lets you know when fully charged. Sorry, I just let it go for a few hours.
