Questions & Answers

Is it safe to use in a hot tub until the repairman arrives to install a new heater? Is the fiberglass bottom going to be harmed as a result?

This product does not work in my pond, so I had to return it.

I'm not sure how to tell if the unit is turned on or not. It's in the pond with me, and it's not even hot. Is there a temperature at which it turns on? thanks?

Yes, it activates at a specific temperature, but the water will not feel warm, but it will keep the fish warm. If it was hot to the touch, your power bill would be excruciating. We also connected it to an air line, which will keep a significant portion of the surface de-icing. We knew it was working because it had iced. There was only a small amount of de-icing (maybe 3 inches) if we did air without the heater. iced surface, but if we used air in conjunction with this unit, we were able to keep nearly a third of the surface (700 gallon pond) de-iced. iced. We had no doubts that it was effective. We never lost fish over the winter, and after particularly harsh winters with the heat and air, we had better breeding results.

I have a 35 gallon preformed plastic circular pond that is 38" x 14" deep and still has frogs in it from this summer. Is it going to be too big or too hot?

I used it in a pond I created out of a kiddie pool. Even though ice formed on the rocks, it kept the waterfall running all winter. Algae formed in the same way that it does in the summer because the water was "warm," but it wasn't particularly warm. In the 1940s or 1950s, at the very least.

Is this something that actually works and saves you money on your utility bills?

Most of them don't work, and this one is no exception. It's a shame, because I still need a pond heater like this, but one that is dependable. Take a look at the reviews; there are almost as many one-star reviews as there are five-star reviews. I bought one and it never worked, never did anything, and I lost two goldfish because I failed to take precautions and dump some warm water every now and then to keep the temperature a little higher. They also wanted me to pay to return it, which I was able to avoid thanks to Amazon's return policy.

Arrived in a state of death and does nothing
3/5

So far, the item has arrived dead and has done nothing. I put it in the pond that is well under 300 gallons two days before a freezing snap when there was no ice in the water, plugged it in to give plenty of time for the thermostat to read temperatures are dropping to freezing and turn on, but yesterday the pond had a layer of ice on top and no fish were around it, indicating that it is not doing what it is supposed to do or working at all. I double-checked that it was plugged in and that the outlets were operational, both of which were. The company said to put it in the freezer to make sure it worked, but that's easier said than done with most freezers, and even if it did, it's still useless because it allowed ice to form all around the pond and didn't make a hole anywhere above it, and there are no fish around it, indicating that there's no or too little heat radiating off of it and rising. I emailed the company pictures of the frozen pond above the deicer, and the response makes it seem like they actually want me to pay to send it back so they can inspect it, because there was no pre-paid packaging slip, and they require me to return it for a refund or replacement. I checked the small pond this morning and it is just as frozen as before, which I photographed and sent to the company; if they insist on charging me to return it, I will return it through Amazon for a refund, hoping to avoid being charged to return a defective non-functioning item.

It didn't work the way it was supposed to
3/5

This deicer is supposed to turn on when the temperature in the pond drops below freezing, preventing the pond from freezing over. That has never happened to me before. I'd have to break or pour hot water over the ice that this heater couldn't stop from forming, then pull it out of the water, where the freezing air temperature would magically turn on the heater. I could then toss it back into the pond and let it do its job. The heater would keep pumping if the weather remained bitterly cold, keeping the water from freezing, but if it got warm enough to turn itself off, it would not turn on again until I pulled it out of the water, exposing it to freezing temperatures! It was a huge letdown, and I'm on the lookout for a new one that will both work and not fry my fish. According to Amazon reviews, this one sounded pretty good, with no reports of overheating, pond liner melting, or fish being killed. And while it met those criteria, it fell short in every other way.

It didn't work out
3/5

This is something you should not buy. I should have paid attention to what the other people had to say. This product was completely ineffective. Outside, my dogs have access to two 4x2x1 aluminum galvanized stock tanks. They have a capacity of about 1. Each one has a capacity of 40 gallons. I had this in one and a "K" in the other. H Pet Products Ultimate Stock Tank Deicer w/ Cord Clip Red 500Watt" in the other, which I've used for two winters. The temperature fell to 26 degrees Fahrenheit. On two consecutive nights, the temperature dropped to 27 degrees and then 30 degrees, while the daytime temperature remained in the 50s. Both nights, the heater broke down. Every morning, I checked it, and it was as cold as the ice on the stock tanks' tops. Yes, I am aware that this unit only consumes 300 watts in comparison to other similar units. Although the other has 500 watts, 300 watts should have been enough to keep 40 gallons of water ice-free at 30 degrees. I had a deicer/de-icer that was 250 watts. icer that kept the same stock tank ice-free until hard water mineralization caused the metal heating element to crack. DO NOT PURCHASE THIS "K" br>br> Thermo-Flex H Pet Products Submersible Pond Deicer Gray 8" x 8" 300Watt" unit from Pond Perfect Climate. br>br>Choose "K" as your letter. Ultimate Stock Tank Deicer from H Pet Products. It is available in a variety of wattages. Alternatively, you could purchase a heater or deicer/de-icer from the "Farm Innovators" brand. Ice cubes are a great way to keep things cool.

All of our Koi were killed
3/5

This heater was purchased for our pond and installed. It worked for the first two days, and we were overjoyed that we could finally turn our pond into a home for the Koi we'd always wanted. We adjusted the pH of the pond's water and added a water conditioner, and once everything was in order, we purchased the Koi, acclimated them, and released them. We went outside to check on the Koi this morning. All of them had died. Last night, the heater broke down, and the water temperature became dangerously low. This heater is low-cost. If you need a heater, please get a better one and don't waste your time with this one. I'm so disappointed that we spent so much money on the fish and accessories only for them to perish.

It's not what was advertised, and it's a huge letdown
3/5

Despite the fact that this is a submersible pond, it still needs to be de-watered. It's also depicted as a floating pond de-icer. I wanted something a little icier. When it arrived, there was no white attachment to turn it into a floating de-icer, as shown in the pictures. icer. When I called the company, they informed me that the attachment was no longer in use and that it would not float. This de-icer was supposed to be used if the water was more than 18 inches deep. I was told to put the icer on a rock and bring it closer to the surface because it wouldn't make a hole in the surface ice. I think I'll be able to make it work by placing it on a rock ledge, which will bring it closer to the surface, and hopefully this will work. I am extremely dissatisfied with the company's Amazon misrepresentation of this product. This isn't what I was looking for, but it's already in the water, so there's no way to get it out. All I want from it is for it to get us through the winter. 1/16/17. Anyway, I made the decision to return it. Amazon was extremely helpful in assisting me in achieving my goal. My money was refunded, and I was able to purchase another floating pond decontamination system. icer. Now I'm in a good mood! Thank you so much, Amazon!.

There is not enough warmth
3/5

I read the reviews that said it didn't warm up their pond well, but I figured it would be fine for us because we only have a 100 gallon pond. br>br>While the water doesn't ice over, it is definitely not warm. I can touch the metal coils with my hands and 30% of the time I might feel some warmth there. Even so, making a dent in the pond is insufficient. The fact that the fish do not congregate around it indicates that there isn't much heat present. I can tell you that the water temperature is still just above freezing, but my koi are still hibernating.

This was a terrible product that didn't work at all
3/5

My pond water was actually electrified, killing my fish, and I was shocked when I put my hand in the water to retrieve my dead fish. I'm not sure if my fish died from being too cold or from electrocution, but they all died as a result of this defective product.
