Immersion Water Heater,with 304 Stainless Steel Cover Intelligent Temperature Control and UL Certification Portable Bucket Heater Heat 5 Gallons of Water in Minutes

I needed emergency heated water outdoors in frigid temps, and I needed it fast. I am very well pleased with this immersible heater but PLEASE BE CAREFUL! This unit gets hot REALLY FAST! In less than 30 seconds of being plugged in, it will burn your skin so please follow instructions. Do NOT let kids use this unit. It can heat a 5 gallon bucket of water from a skin of ice on top to 167 f (75C) in mere minutes. Then it shuts itself off. Because of how powerful this heater is, I can absolutely understand how you would not want to use it in any situation that you are not present. For my purposes, it worked flawlessly in sub-freezing weather. The quality seems good, but the instructions state that there is a red indicator light that lets you know it is on....um...no, there is no red light. The cord length is rather short, but the instructions clearly state that it is safe to use an extension cord---CAVEAT--- MAKE SURE YOUR EXTENSION CORD CAN HANDLE THE WATTAGE. And even then, that extension cord might get a little warm. Mine did. I appreciate the auto shut-off and the apparent durability. The bright yellow color is attractive as well. I think this unit is well worth the money. It certainly helped me on the farm.

Works fast and get really hot- we used this to heat up our pool in the Spring! We bought it for a stock tank, however it gets too hot to leave in for an extended time. For quick heat up it’s great. Not designed to be left in during the winter for animals.

*edit from previous review. Company was excellent and reached out to me to make things better. They shipped me a brand new unit for free and I said I would honestly review them better if all was well. Sorry folks, used in the hot tub several times with no issue but left it in there overnight last week and reached in to grab my filter to change it and got a nice jolt of 120v up my arm. The new one, like the other one, apparently cannot be used at high temp (its own setting) without shorting out or losing it's seal, not sure which one but it is an open current right in the water. I had a temp monitor in there to track the temp and it reached close to 130 degrees overnight in a 5 person inflatable tub. I know, I should not have left it on overnight but if you leave your pool accessories on overnight you don't usually worry about them electrocuting you the next day when you take a dip.I do not say this lightly, do not use this with humans or animals in or in contact with the water, you can be electrocuted. May not kill you but I am not sure who wants to find out. I certainly would not want to be chest deep in the water and have it zap me.Original review below------I have been using this device for a couple weeks to enhance the temp of an outdoor inflatable hot tub. I would run this for many hours at a time. The other day when I was closing up the tub, I plugged the unit in and I was replacing the cover when I touched the water and felt a jolt. I was barefoot at the time but there should not be an open current from the unit in the tub. It was not a deadly jolt so I wanted to ensure this was what was doing it and I unplugged the unit and touched the water, no issue. I carefully plugged the unit back in and touched the water again, no doubt, there was current running though it. Not enough to kill me but not gonna experiment and find out. It is being returned and I will not get the same brand again. For anyone reading this that might use this for a tub or kiddie pool, do NOT take the chance of having your kids, pets, or livestock near the water when this is plugged in. Mine might be a single bad unit but I doubt anyone reading this wants to find out there hard way that I am not alone.

The heater works as designed and intended. It heats water as fast as physics will allow it. Meaning, if you put it in a smaller container, the result will be the entirety of the water in the container will be heated much faster than if you were to put the heater in a large container, say bath tub.So, get your heat on.

The product was just like picture. It works as it should. The temp gauge gives accurate readings of the water. I would have given it a 5 star, if it heated the water faster. It took a good 1.5 hours to get temp to 100, in cast iron tub. It works just not as fast.

Great? Bought a few years back! Still work like a charm after all this time

Got this heater with a battery operated pump shower system. It's a lot of power generated really quickly, typical of heating elements. The time it took to get a 5 gallon tub that came with the shower system took about 20 minutes to get from 45 degrees Fahrenheit to 99.5 degrees Fahrenheit. Everything about this heater made me nervous to use from the directions to the reviews. I understand directions just covering their rears with liability so with any electricity and hot objects use common sense and best practices. I plugged it into a surge protector that I have to not blow my fuse and the surge protector made a clicking noise while using so prob won't try that method again. It's an older 5 year old protector without much use. The cord did get warm to touch, not scorching or even hot but noticeably warm. Wish the cord was longer due to arrangement of outlets in bathroom. Def nowhere near the quick times that they advertised with my particular heater. It does work, much slower than advertised, and it is sketchy to use but that may be my own anxiety after reading reviews etc. Def not something to leave for any duration of time without watching while in use. Did not burn my water tubs that like rubber or the same material as rain ponchos or inflatable pools.
