Great heater even in MI. Kept pond flowing all winter

Followed all instructions, put this in pond. It "sizzled" for a minute then never worked, never heated the pond at all. At least it didn't kill my fish.

If you have a small koi pond like me, this is overkill. Not only did it melt the ice, it heated the water to the point the fish thought it was spring and woke up. Also, it really makes the electric meter go round and round, so don't leave it plugged in constantly. Unit has nice long cord too.

BEWARE just a 6' cord though sold as 15' cord

Works as advertised. I'm using this in a decent sized Koi pond in the Northeast and the pond has not skinned over once. My fish are loving the warm spot it creates for them. I would have given 5 stars but a spiral rod which holds the optional guard in place was missing from the packaging.

Beware. Product describes a 15ft. cord with this unit and it is not! API manufacturer label on the box clearly states a 6ft. cord. A external label (assume used for picking) states it's a 15 ft. cord. It is not. Disappointed.

I have been using these for years for keeping my pond defrosted during the winter. Lately I am only able to find the 6ft cord. This 15ft cord is a life saver, it gets out more in the middle if the pond and keeps the wild life from hand picking my fish, when they gather for warmth.
Very happy!

So far so good. I purchased for my small fish pond. I got tired of bringing my fish in every winter and cleaning an aquarium. It is working just fine and my fish are alive.

I ordered this to thaw out a septic holding tank, it was received very fast and quality looks good but further research found that it is not legal to use them for this purpose. So I will probably end up returning it.

Works as stated. We use it to keep our pond water from freezing in a very cold climate.
