So far works really well! Glad I got it for our 7x2 stock tank pool I have it on its own outlet Probe sensor and all seems high quality. So far so good. Love how it stays on forever in the water and I paired it with my smart switch

I'll never go camping again without a portable immersion water heater like this one. Being outdoors, I wanted to take a bath and the river water was freezing cold, so I found a bucket and I had hot water. Super super easy to use, works great and lasts a long time. It heats water quickly and evenly, reaching the optimal temperature in just a second and reducing preheating time. You could use this heater for several things you need to heat. One night when we were camping, I made ramen, just heated the water and that was it! I love its size, it's perfect for easy transport from one place to another. I like its safe design, and it's also very easy to clean. This heater is made of 316 stainless steel, is waterproof and quite flexible and powerful. Highly recommend it.

This immersion heater really delivers when it comes to heating water quickly and efficiently. The 3500W power makes a noticeable difference, and I like that it comes with a thermostat and GFCI for added safety. It feels sturdy and well-made, which gives me confidence using it in different types of pools and tubs. Setup is simple and doesn’t take long, and once it’s running, it maintains a steady temperature without constant adjustments. What stands out most is the versatility—it works for inflatable pools, hot tubs, and even baptismal pools, making it a very practical tool to have on hand. Overall, it’s a strong performer that combines safety, ease of use, and dependable heating.

The media could not be loaded. I think there might be some confusion on this product which is something the seller should address to get better ratings. This Submersible Water Heater comes naturally with a 120V – NEMA 5-15P style plug that fits your normal American electric outlet. It also comes with an extra adapter plug that turns the end into a NEMA 6-15 style plug. This plug is for a 220v power source. Given that this device will works with both 120v or 220v power and automatically recognizes which power is coming through; however, if you are just using the 120v - NEMA 5-15P plug then you will only get about 1800W from this 3500W submersible water heater. That is why many people have mixed results in my opinion on this water heater. If you want the full 3500W coming through, then you need to use the adapter. The seller does not clearly state this, but should if they want great reviews because this is a quality product that does work. It takes it about a day to bring a 2000 gallon pool, pond or baptismal up about 20 degrees F or so. If you have a cover for your body of water that you can use that will help with bringing up the temperature quickly. It is easy to use and easy to set up. Overall, I think it’s a good product, but there needs to be more information given about it.

If I could give it zero stars. That’s what It’d be. SMH Had this thing in my pool for 12 hours. Went up from 74.4°F to 74.6°F. Can’t even get my money back because pool came late and it’s all past my 30 days 😡
