    • Great for stock tank hot tub
I bought this for my 8' stock tank pool to make it a hot tub during the winter. 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. ... show more

    • A Frustrating Journey: Two Defective Hot Tub Heaters and Disappointing Support
I recently encountered a frustrating issue with a defective hot tub heater and feel compelled to share my experience. Unfortunately, I have already gone through two of these heaters, and both have failed to meet even the most basic expectations. The initial heater I received suffered a catastrophic failure, resulting in the complete meltdown of the top cover. This occurrence was not only a significant safety concern but also a complete disappointment given the short lifespan of the product. Hoping that the second heater would fare better, I reluctantly purchased another one. However, after just a few months of use, it became evident that the heater was not functioning properly. It ceased heating beyond 92 degrees, a significant drop from its advertised capacity of 104 degrees. Concerned about this decline in performance, I promptly reached out to the customer support team for assistance. To my dismay, their response was dishearteningly dismissive. They suggested that the use of chlorine, a standard chemical for hot tub maintenance, may have corroded the heater, leading to its malfunction. I found this perplexing and frustrating, as it seems counterintuitive to advertise a product specifically designed for hot tubs while prohibiting the use of chlorine—a common and necessary chemical for proper maintenance. In an attempt to resolve the issue, the support team forwarded me a form that required me to open up the unit and perform various tests on the cables to assess resistance levels, among other things. However, I firmly believe that it is the responsibility of the manufacturer to ensure the functionality and reliability of their products, especially within the stated warranty period. Asking customers to troubleshoot the unit themselves is both inconvenient and unprofessional, particularly when the product's heating capability deteriorated within a mere few months. I had hoped for a more collaborative approach to finding a solution. Compounding my disappointment, I had taken the precaution of purchasing the Asurion warranty from Amazon, which was bundled with the product. However, when I attempted to make a claim under the warranty, I was informed that the hot tub heater I purchased is not supported by the warranty due to it not being considered a compatible brand. This raises the question of why such a warranty option is even offered if it does not cover products from certain manufacturers. It is deeply frustrating to be denied coverage after taking the initiative to protect my investment. ... show more

I bought this heater understanding that it had limited functional uses. Specifically, it could hold temperature much more readily than it could bring a non-heated body of water up to temperature. Also understood it cannot be used with a weak pressure flow pump, or for large volumes of water. So far, my experience is that the pump will not provide any heat whatsoever. I have had it professionally installed (union plumber) and have paired it with an spa-industry standard “Grundfos” circulating pump. Drained the tub today and “un-installed” the heater. Confirmed that it does heat when the flow switch is tripped and the dial is rotated calling for heat. Problem has to be the flow switch not tripping due to a lack of sufficient water pressure from the 3/4” pipe I used. Like other reviewers, I epoxied a larger plastic “washer” piece (I used the bottom of a pill bottle) onto the trip lever. My thanks to other reviewers for emphasizing the units integrity if installed per the mfgr. Specs. Will post further after installation and testing. UPDATE: More frustration as the large “washer” I installed apparently reduced waterflow too much; resulting in pump surging. I fabricated a metal (not plastic) trip lever extension that closely matched the existing trip switch and I attached it mechanically rather than with epoxy. RESULT: This Heater will HEAT! I left the system on overnight and discovered the temperature to be at 112° the next morning. Now that all the components seem to be playing nicely together, all that remains is to calibrate the temperature dial to real world experience. This product would be improved greatly by the simple addition of a small indicator light that shows “on” confirming when the heater is actually heating. ... show more
