Review: Very Good Spa Heater - Used it to replace a huge propane heater. Doesn't work as fast, but, very energy effective. Electrician, plumber and pool guy all gave me a hard time, so, I hooked it up myself with no problems. Pool guy has 30 years experience and can't believe how well it works.
Review: Terrible dangerous product that should not be on the market. - This is a terrible product. The first one I had lasted 2 years and then failed to heat. Customer service diagnosed a bad part but since it was older than a year I had spend an additional $60 to buy it. Changed the part out and the heater worked for about a week then died. I ended up buying another one thinking it was just bad luck with the first and to keep plumbing easy as pipes were routed specifically for this model. The second unit is less than a year old, used twice and it has failed in a very dangerous way - heating the hot tub to 120F with no ability to control it. Do yourself a favor and buy a reputable unit from Hayward or Raypak.

### ⭐⭐⭐⭐ Love it and hate it
*by E***O on November 4, 2020*

I purchased this heater to heat the water in my 10ft (a bit less than 1,000 gallon) Intex pool to a warm temperature (about 90F max) - so not for heating a hot tub. I got it in an Amazon warehouse deal for a price that's about 30-40% lower than regular so I considered that a great a deal. Now, when our electrician set it up, it did not work at first. First we thought it was a flow issue, but when we did all the calculations, we figured we have a higher flow rate than what the device required. Electrician left, unit turned on for a second, but the display did not stay on (i.e. did not sense the flow), so I was about to call customer service. Next day my husband took off the cover and moved/reinforced all wires, bits and pieces and reset the temperature sensor - hallelujah the unit started to work! And it heated the pool water beautifully... then a few days later, it started to trip the breaker and we had no clue why. Then it again worked unexpectedly, then again it did not. Called the electrician again, he replaced the GFCI breaker with non-GFCI and that fixed it, hopefully this time for good. All in all, this unit has given me a lot of grief when it did not work and my daughter would have wanted to splash and I could not heat up the water, but when it does work, it's really good. It's now taken down for the winter, we'll see again in the spring... but honestly, had it not been a warehouse deal and had I paid full price + the cost of the electrician twice on top, this unit would have costed me a fortune already. Well, it kind of did. The only reason why I wanted it so bad was because all other reasonable units run on propane, which I hate, and I wanted a small and slim electric unit that does the job. This does, when it works. Also a better manual would come handy.
