At least by the time ive using it it works well for its intended use. The only thing I would like it had is an indicator light to know its working, anyway you find out its working if the water keeps hot. Review: Shorts out - The thermostat on this item shorts out after about a months use. It work very well until it didn’t work at all. Wasted money ## Features - [Constant Temperature Control]: Use the temperature knob to set and maintain the desired water temperature from 0 to 45°C. Once the desired temperature is set, the thermostat continuously monitors and adjusts the operation of the heating system to maintain the water at a constant temperature. - [Connect with Circulation Pump]: Spa heater have to connected with circulation pump with power of more than 0.5HP. Smaller pumps may not provide enough water flow to activate the heater. Also, the spa thermostat has to be with a circulation pump rather than a booster pump or submersible pump. - [1.5" PVC plumbing]: Mxmoonant hot tub heater is equipped with 1.5" PVC pipe fittings, so you should use SCH 40 1.5" PVC pipe for the plumbing connection. A smaller size may result in insufficient water flow. If you want to use other pipe sizes, please note that everything should start with 1.5". - [Tips for Heating]: It's recommended to fill the hot tub with hot water instead of cold water, as cold water can impact the heating performance. Additionally, it's advisable to limit the water capacity to no more than 400 US gallons and to use an insulation cover to retain the temperature. Otherwise, it may take a long time or may not heat up at all. - [No Plug]: The pool thermostat does not come with a plug as it is a high power device. It should be connected to a 25A GFCI circuit breaker. It is recommended that you find a professional electrician to complete the circuit connection. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CF4BXSR2 | | Best Sellers Rank | #150,041 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #113 in Swimming Pool Heater Parts | | Customer Reviews | 3.4 3.4 out of 5 stars (43) | | Item Weight | 3.76 pounds | | Manufacturer | Mxmoonant | | Package Dimensions | 8.94 x 7.48 x 7.17 inches | ## Images ![Mxmoonant Hot Tub Thermostat, 2KW 110V Spa Bathtub Heater Thermostat with Temperature Control for 400 Gals Hot Tub, Whirlpool Bathtub, Spa, Small Pool (No Plug) - Image 1](https://m.media-amazon.com/images/I/71TDP8+8aAL.jpg) ## Questions & Answers **Q: Why no plug but need to be wired?** A: The pool thermostat does not come with a plug as it is a high power device.

Wasted money ### ⭐⭐⭐⭐⭐ Hot water heaven! *by C***C on June 11, 2024* I bought a whirlpool tub several years ago and installed it in my den (i.e. my getaway) bathroom. It's a great tub but the problem with it is the water cools down too fast. Sitting in it for any period of time any longer than what a bath would normally take allows the water to become uncomfortably cold. You can't really enjoy the benefits of the whirlpool features. You can keep adding hot water, but that gets old. When I saw this great hot tub heater by Mxmoonant, I was instantly excited to get it installed ASAP! It turns out that the tub plumbing has a little section that is removable in order to insert an in-line heater! Who knew? What a difference a little circulating heat will do. Now there is no need to hurry out of the tub because it's getting too cold. Now all I have to worry about is my fingertips getting waterlogged! Well made, quality heater. I recommend it!
