Nights are getting colder, so we got this to try to keep our above ground pool swimmable longer. After a cold snap of three 60 degree days 40/50 degree nights the pool went from numbing your legs I won't allow the kids in it to cold, takes a long time to get used to but manageable. You can literally see the heat radiating off the thing. I accidentally touched the water and it did not electrocute me so I'm a fan so far. Worth it for $25 if we can keep this pool open 6 more weeks. Will update if I change my mind.

5.0 out of 5 stars For bathtub when boiler goes out and no hot water for shower.
Reviewed in the United States on June 24, 2022
Verified Purchase
I live in a prewar apartment building where the boiler goes out a few times a year, sometimes more, with no notice. This will heat a large bathtub, filled 2/3 of the way with cold water, in one hour, to about 92 degrees, which is very tolerable for a quick bath. Buy a long heavy duty extension cord for use in an outlet if you don't have an outlet near enough. Hoping it gets me through any outtages to come.

I used this product to heat my tiny pool. Worked great for about 90 days, then the top housing became detached, which loosened the wires. Now it works intermittently. This would be a great product, but with only a return window of 30 days, I wouldn’t risk purchasing it again. Be wary of other heaters with a similar design.

Reviewed in the United States on February 14, 2024
Color: YellowVerified Purchase
I've used these at least 15 times. I bought 2 and use them at the same time. One gets plugged into a long extension cord that is plugged in a different room, the other gets plugged into my outlet by the bathtub. While the extension cord gets a little warm where it connects, it's never been hot. The cord plugged into the outlet hasn't caused any problems, but does spark when i unplug it. I can't believe there are reviews complaining that they can't be IN the water as an electrical device is on and running in the water. My hot water tank broke in the middle of winter. I dont have the money to replace it, so I use this to warm up water to bathe in. I use 2 at a time. I'm not sure the temperature my water starts at, but it's VERY cold as it's winter and the hot water tank is turned off. If I had to guess I'd say just above freezing. Maybeeee 40⁰f. With 2 of these running at the same time, my bathtub full of water is burning hot around 2 1/2 hours later. I let it get too hot, and just add some cold water in, instead of constantly unplugging and removing the devices to check the water temp. If my starting temp wasn't so cold, it would heat up to my desired temp much faster. At 2 hours the water is lukewarm warm. At 2 1/2 hours it's too hot and I need to add cold water. I love hot baths so I'll gladly take water being too hot and needing to add some cold water, compared to the water being too cold and not being able to add hot water. I check on them and feel the outlet/cord temp every 10-15 minutes just to be careful. I'd buy them again.

I have an inflatable hot tub and I wanted it to be just a little hotter so this works great takes about an hour to 2 hours depending on how much hot are you want it to get? But if you want to get that little bit of a boost or maybe your hot tub isn't heating up so much anymore this is perfect.

5.0 out of 5 stars Est-ce utile pour une piscine?
Reviewed in Canada on September 26, 2022
Verified Purchase
L'explication du calcul peut sembler rébarbatif mais lisez jusqu'à la fin pour la réponse

J’ai acheté ce chauffe-eau pour une piscine de 15 pieds de diamètre. Une telle piscine contient environ 20 000 litres cube d’eau. L’équipement consomme 1500 Watts. Le 1500 Watts correspond à environ 1290 kilocalories/heure 1 kilocalorie permet d’élever la température d’un litre d’eau de 1 degré C. Tout cela pour dire que l’équipement peut par calcul en théorie augmenter la température de l’eau de ma piscine en 24 heures d’environ 1,5 degré C ou 2,8 degré F (1290*24)/20 000. Évidemment ce calcul est théorique et n’implique pas de perte de chaleur de la piscine. En pratique j’ai fait un essai pour une période de 24 heure pendant un moment ou l’eau de ma piscine était au départ à 22 degrés C (72F). La température ambiante la nuit descendait à 14 degrés C et le jour elle remontait à 24-25 C, J’ai débuté le test vers 18 heures. le lendemain matin la température de l’eau n’avait pas changé malgré la nuit à 14 degrés C. après la journée soit le 24 heures écoulés, la température de la piscine avait monté d’un degré C soit environ 2 degrés F.
Les températures ambiantes ayant changées drastiquement par la suite je n’ai pas poursuivi le test. Je sais qu’il y a une multitude de facteur qui peuvent influencer ce résultat et que mon thermomètre n’était pas de haute précision mais j’ai une tendance à penser que l’équipement a performé à la hauteur de mes attentes. Je sais que cet équipement est moins efficace que les chauffe-eaux vendus par les équipementiers de piscines mais pour une petite fraction du prix des chauffe eaux des Trevi et Club piscine je crois que je peux donner un petit coup de pouce à la température de l’eau de ma piscine pour la rendre un brin plus agréable. Je suis donc bien satisfait.

Reviewed in Canada on February 14, 2023

I wanted to use this immersion heater in combination with a thermostat to warm up a water bucket in my farm this winter. I wanted to test what will happen if the heater is taken out of water to assess its suitability and possible risks. As it should be, the heater stopped heating in less than a few seconds for security reasons to prevent fire. The big surprise though is that the fuse is built-in and there is absolutely no way to access it or to replace it. Therefore, the unit becomes useless and totally dysfunctional forever. Shamelessly, it is clearly stated in the user manual that «If the fuse fails, the heater will permanently shut off». What a fragile toy, what a joke. Save your money (40$+tax).

I have a 16 ft pool, 4 ft deep. Set it up and the water was FREEZING. I kept it in the pool heating over a few days. Left it in overnight. After 4-5 days my pool was warm. With the sunlight too, it went from 67°F to 84°F . As long as you follow the directions to a T.... IT WORKS GREAT. Don't turn it on unless it it fully submerged. Don't take it out until it's been unplugged and cooled down for a few minutes. Easy. People who have this and it set on fire, CLEARLY didn't read the instructions. It says KEEP FULLY SUBMERGED TO AVOID FIRE. ... plus I got the 4$ 2 year warranty in case it breaks.

3.0 out of 5 stars poor quality control
Reviewed in Canada on February 20, 2024
Verified Purchase
I don't know why, but I have had different results from different colours. Maybe it relates to when they were manufactured and what suppliers were being used at the time for internal components.
Definitely DO NOT buy a used one from the warehouse. The used ones I tried did not work at all. My comments below relate to new items.
white version: The quality of these is hit or miss. Some work great. Some don't work at all. Some work but not at the 1500 watts advertised. The ones that work are 5 star. I had to purchase 10 to end up with 4 that work after a month, so 3 star overall.
yellow version: similar results but not as many had to be returned.
