Farm Innovators Model H-419 Ice Chaser Cast Aluminum Submergible Tank De-Icer, 1,500-Watt

Installed in the coop inside one of those standard green bottom waterers. We see inside coop temps in the teens, outside to -25. So far so good. I've installed it on the same timer as the lights and it heats/thaws the water out easily every morning for the girls.

Heaters work well, dont burn out as quick as most other heaters

Purchased for a 5 gallon bucket with horizontal water nipples in the chicken coop. It's been down in -15 in the coop (no other heat source) and so far has worked great! Would buy again.

Its hard to complain about this item when its -20 and your not carrying 5 gallon buckets of water for your horses.The Good...- ( were in Alaska ) When its -20 in a 100 gal rubber maid plastic tank the water is ice free. ( probably 75-50 gal in tank )-Has coiled ( I assume zinc over steel ) cable protector for those horses that play with cords cord is also long enough to make it out of deep tanks and very stout.-stand offs keep it off of bottom of tanks ( can be used in rubber maid tanks )-sits on bottom of tank ( our horses used to throw out the float type ) i think this one has a thermal protection in case that does happen ( not confirmed )The Bad...- I wish there was a way to modify the thermostat ( I don't know the exact temp but our water is very warm say 40°+) i'd like it only above freezing not a problem with one horse but if you have 15....Comments:please note this is 1500 watt, if you have one circuit and you string a bunch of these together expect to pop a fuse. ( should not be an issue most of the time but below zero these things come on a lot )-there were some comments about longevity, this is a great unit ( above par with other units ) its not stainless steel and it does have a cord on it, we've gotten about 3-4 seasons on our last one before it died ( and we ordered another one, and we will again in 4 years... )-costs... its 1500 watt, if you live some place where its cold and this is on all of the time its like having 15X 100 watt bulbs on. its not bad, its whats required to keep it ice free when it has warmed up the water enough it will turn off. ( other have given this a low rating because of the power usage, if you only need a 250 watt one your ordering the wrong one... this is the monster truck of water heaters. ( some may need other may not )

Amazon tells me I last ordered this in 2014 so I got 9 years of use out of it (my current one started tripping the breaker). I use it in a 5 gallon water bucket for chickens. The water never froze in the bucket but the water nipples outside the bucket would freeze in extreme temps.I probably could have gotten more life out of it had I not left outside at the chicken coop (unplugged) year round.
