I read other mixed reviews that had also bought it for converting a stock tank pool to a hot tub. I gave it a try because I didn't want to setup a propane instant hot water tank setup. It did take a couple trips to the local hardware store to get all the proper fittings but I got it all connected and up and running. I did run into the same problem at first of the heater not kicking on so I tried taking the top cover off like others said they did and I tricked the switch to be on. Also I did have to plug it into a 20 amp plug. While I was trying different things, I had changed the filter on the Intex 1500 filter pump and noticed the flow switch was working like it should so I put it back together with no modifications and it works great, I just change the filter every 2 to 3 weeks and have no issues. I did also buy a Bayite temperature controller plug and plugged the filter pump into it on the heat plug and have the temp set to turn off at 100° and have it kick back on at 98°. I did have to change the plug on the Intex filter pump to a non GFI plug because every time the temperature control plug shut off when it reached 100° the GFI plug on the pump would pop off. I have had no issues in 2 months now and am loving it. It did take a few days to get up to temp, I live in the foothills of California and the temp here recently has been in the high 50's to low 60's during the day and mid to high 30's overnight and it keeps it to temp with no problems. I have a blue bubble cover and a black 8' pool cover on it to help keep in the heat. Review: It has a factory defect - The heater worked really good,, but it was short lived, I purchased it on June the 8th and I didn't install it until July for my outside jaccuzi, this is now September the 19th and it has stopped working so I probably used it I'm guessing 12 times ,it never operated constantly, I would turn it on or off after each use, the power supply was good and sufficient enough to run the pumps and the heater,I don't know how to contact the seller, so I guess I'll look for another brand,it was refreshing for these old bones of mine while it lasted, I was hoping to get at least a year out of it, I'm only 68 years old but I have a lot aches and pains that is reduced by getting in the hot tub it's also getting harder for me to get up and down to do mechanical work that's why I like the hot tub it's sad that the heater quit working after only 2 months,. The heating element is 2000W at 18 amps . And the thermostat is 16 amps. So guess what happens, it burnt out the contact points on the thermostat, and the overload protection switch did nothing to stop it from overheating and the knob on my thermostat MELTED. Not only that when I took the cover lid off there's moisture getting inside, it's a safety hazard. Buy something else, it will save your life. ## Features - Requires a 20A circuit(Connect 20A adapter or breaker),with 1.5" outlet , min 0.35MPA pressure,suggest work with at least 0.25HP,suitable small bathtub & spa tub /hot tub 2 KW /110V-120V.No plug, just 3 cables,Black Cable is Live,White Cable is Neutral,Green Cable is Grounded. - We suggest water capacity not more than 400 US gallon,the heater won't work if it exceeds the standard, see the picture 2. - We suggest the pump not less than 200 wat (3600 L/ h), small pump will cause the heater cannot work,see the picture 3. - Make sure the mount direction is correct,arrow direction is the water flow direction,wrong direction will not make the heater work. see the picture 4. - A quick method for detecting heating pipe damage,see the picture 5. - When the heater doesn't work,use a multimeter to test the 4 points to determine which component is damaged,see the picture 6. - If have any issues with heater,please take some photo of the using environment,including installation direction,set temperature,pump and water capacity,we will help you troubleshoot. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #239,234 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #100 in Outdoor Heater Replacement Parts | | Customer Reviews | 3.7 out of 5 stars 688 Reviews | ## Images ![Hot Tub LX H20-Rs1 Thermostat 110V 2kw | with Adjustable Temperature Thermostat for Some hot tubs,Underground Small Pool (Suggest Connect 20A Adapter or Breaker) - Image 1](https://m.media-amazon.com/images/I/81XZM5J0etL.jpg) ## Questions & Answers **Q: Mine leaked electricity into the water dont buy they are dangerous!!!!!** A: Yes it leaked and turned out **Q: I want to use this on my outdoor spa tub. details and description do not say indoor only, instructions say for indoor use only. can it be used?** A: I use it on my outdoor lap pool, but obviously it needs to be protected from the elements.

The reviews here are hit or miss, but I have nothing but positive things to say about it. We’re hitting 110 degrees, but here are a few critical tips if you’re using it with a stock tank pool. 1. Wire it up to a heavy duty plug and use it on an otherwise unused gfci protected outlet. I wired mine to a heavy duty outdoor extension cord and it works fine. 2. You need to have good flow from your pump in order for it to activate. Like someone else here posted, I epoxied a large fender washer to the metal flapper arm on the outlet side of the heater. Before that, even with our 1500gph Intex pump, the flow switch would only occasionally engage (you can see this if you remove the top cover and watch when you run water through it. With the washer it engages with authority. 3. It took me about an hour at Lowe’s to get the fittings together that would allow me to hook this up to my pump and outlet valve, but the most critical part was buying a length of flexible hose meant for pool cleaning accessories (also from Lowes) and a couple flexible rubber reducers. 4. The most important part that I learned was that these things take a good bit to get up to temp. I thought mine wasn’t working because I felt no heat from the unit in the first hour or two. The issue was that with a large 700 gallon tank like ours, the initial heat takes a good 12 hours. The water hit 95 degrees in 12 hours, but went all the way to its max of 110 degrees within another 6. Using it with a DIY insulated cover (1.5” rigid foam and redwood fenceboards) I only need to run it for a few hours a day to keep it around 100 degrees. Obviously this is no substitute for a 220v powered, and heavily insulated modern hot tub, but if you like the aesthetics of a rustic stock tank pool but want to use it when it gets cold, this is a solid way to go. ## Frequently Bought Together - UCEDER Hot Tub LX H20-Rs1 Thermostat 110V 2kw with Adjustable Temperature Thermostat for Some hot tubs,Underground Small Pool &Bathtub（Suggest Connect 20A Adapter or Breaker - Intex Replacement Hose Adapter A w/Collar for Threaded Connection Pumps (Pair) - Happybuy Swimming Pool Pump 1 HP 110V Hot Tub Pump 0.75 Kw Water Circulation Pool Pump Spa Pump Above Ground Pool and Whirlpool Bath --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/93465409-hot-tub-lx-h20-rs1-thermostat-110v-2kw-with-adjustable](https://www.desertcart.tn/products/93465409-hot-tub-lx-h20-rs1-thermostat-110v-2kw-with-adjustable) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-08*
