Immersion Water Heater Bucket 441

I used this to heat a 6x6 inflatable hot tub when it's own heater stopped working. It was able to bring the temperature up to 112° f in a very short period of time.

Works really good . Heats up real fast.

Bought this to heat water in 5 gal buckets for cleaning. Dropped it in one bucket of cold well water, put an identically prepared second bucket right beside it with only sunlight / outdoor temperature for heat source for comparison purposes. Both had same environmental conditions, and both were the same temperature 4 - 6 hours later according to the little thermometer and my hand! The heater made -0- difference, other than using my electric.

I had purchased this for my 10x10 pool and it did nothing to warm up the water after many hours of it submerged. The cord got so super hot it was scary. Just returned it.

Not great but does the job

Started on fire it was horrible melted down made burn makes..warning BLOWS UP

Bought this for my 500 gallon kiddie pool and it heats it up a degree every hour. The ON/OFF switch is a blessing because a different unit i bought has no switch and it sparks at the outlet, in or out..The temperature gauge is 4 degrees off, i tested it against 2 meat thermometers so don't trust it.ON/OFF switch is very good, just plug in and no sparks! Cord could be longer by a foot or two.The metal casing around the heating element has cutouts of little hearts which i found much nicer than basic holes.
