I bought this unit last week and had a 1/2 inch layer of ice on my pond but had a small opening where my water moves. I plugged it in and the next day no ice. Now my pond water is up to 50 degree's and it is 7 outside. I thought this shut off once it...

I don't think it has an auto shut of. Mine does not sit off either, so I put a thermostat on the outlet.

no! You have to return the chill unit to the freezer for at least a few hours. If it hasn't defrosted too much, 1 hour might do it, but it works better when the chill tank is hard frozen. You can buy an extra one which will solve your problem.

I had the same question when mine arrived a year ago. But after plugging it in just before freezing temps, it did the job just fine. The water doesn't even feel warm to the touch, which I'm sure our pet appreciates. So, it just works...

I left mine run all winter in Delaware,as long as the water flows in the filter it won't freeze,however it was so cold this past winter the water started to freeze in the pond and created a dam that prevented the flow of water,so guess what,new filter time. A $300.00 oops. You really don't need to run it in the winter as the fish are in hibernation mode. Just keep the water from freezing solid with a heater or aeriator. Don't recommend buring it as it's too hard to access.

I live in Arizona, so water does not stay cold very long here. I have to say that mine, too, broke.

I do not use it in a wet application, and I would say that it is not intended to be used in a wet application. If you want to keep a hole in the ice, that is one thing, if you want to keep the whole pond warm so it does not freeze, that is entirely a different thing. The amount of BTU's to raise your whole pond above freezing is HUGE, but to just keep a hole in the ice, get a cow/horse trough heater, that is what I use in my pond to allow oxygenation of the water and a place for the fish to eat, although the fish really don't eat much when the water is that cold. sorry for being so lengthy

It keeps my 150 gallon pond a warm 75 degrees, but it fluctuates. It is made for an aquarium, so I would guess it will take a while, but it will warm a 250 gallon tank...though it may fluctuate some. Mine fluctuates about 10 degrees (5 up, 5 down), keep in mind mine is outdoors and the outside temps fluctuate too. ;)P.S. I am very happy with my purchase!

The coils have not iced up but I have only had the unit a few weeks and it is in lower room of a tri level home. So far the coils have not iced up as I said. The unit definitely is taking harmful moisture from the room. I set the level at 40% and it ran continuously and I was dumping the bucket twice every 24 hours. I set in to 60%, and the room feels the same and the unit shuts off some.As with many dehumidifiers, longevity will tell the story of how well this unit is bilt

I put ice in it with the water and the ice doesn't thaw for over 24 hours. I'm in San Diego where summers are quite warm.

I do not know if the cold weather would affect this unit. The one I purchased was defective and I returned it for a refund. The problem was with the timer. I couldn't get it to take the correct time setting and although this was not a biggie for me, because I could easily have it feed the fish a few hours off here or there, on top of the hour setting problem, the amount of food dispensed was not easy to control either. Great concept, very bad execution. I wish the manufacturer got more serious with the quality of the timer used, then this unit would be something very useful for all of us owners of ponds and koi.

Not at all. This whole unit is junk,it barely even chills the water. I trashed mine a while back.

Ice huh. Probably depends on the ice thickness, your water temperature and pressure. This thing will clog up the line permitting water pressure to build but that is all. I would look at a Clog Hog instead. It runs off of a pressure washer and has a metal head that could bash against the ice like it did to my leaves.

This past winter it didn't freeze and I live in Maine, we got about 6" of ice in the tub. We did however, finally get a heater for the tub because it is the farm animals sorce of water. The heater didn't melt it either by the way.

I have used ice twice. Didn't notice much difference from just using water. This is a great unit. i live in AZ and it has been 100 degrees the last few days. this has helped me keep cool.

I have a 750 watt. I live in mid Michigan. I have it on a timer for 12 hours at night. It keeps a open area usually about 2 feet around the heater (pond is less than 3 feet deep there) most days. When its really cold, the circle shrinks. My fish seem to do fine: I have it near the rock pile they hang out in. You could go a higher wattage or just have it run longer. I got it in 2011 I believe so this will be its 3rd winter. good luck

I'm using it at my Koi pond and it works very well. It hit freezing yesterday morning and it worked fine. I will stop feeding soon as the water temp is in the 40's F. If you want to use it in below freezing temps I would recommend putting Lithium AA batteries in it. It's a great feeder.

No, it won't; it just keeps the water circulating when there is sunlight. In a Wisconsin winter, that will just mean some interesting ice patterns in the afternoon. :) You will need a birdbath heater to keep the water from freezing. Unless you have a very large birdbath, a pond heater is probably too big.
