Does better than I expected with a 20,000 gallon pool

Does better than I expected with a 20,000 gallon pool
I bought the pool 27 and the spa 11 but this review is only for the pool 27. I have no idea how this little piece of equipment works so dang good. But it blew away my expectations. I knew it had horrible tech support. I also know it might not last over 2 years, but my options were limited. My pool is indoors. I didn’t want to run gas and vent it and worry about gas and carbon monoxide. So this was pretty much my only option. I could care less if this only lasts 3 years because it is 1/4 the Cost of a gas heater. I can replace it 4 times and still be in it less than a gas one. Now for the performance. My pool is 20,000 gallons. 2 ft on one end and 9 ft on the other. 40 feet long. 18 wide. This heater was not supposed to work. I’m 3000+ gallons over the specifications. However, on Friday I started with a pool temp of 62 degrees and by Sunday it was 85. In 48 hours it raised the temp almost 25 degrees and that’s absolutely amazing. I thought it would take a week to do that. It shown inlet temp and the outlet temp was always between 6 & 8 degrees warmer. After 48 hrs it was up to temp and turned itself off. Is my power bill going to be crazy this month? Yes! I know it will. But I believe now it’s up to temp it’ll maintain it well. It only seems to run a couple hours per day now to keep it at 86. If you’re buying this and asking If it’ll cost a lot to operate just know it will. But it doesn’t use gas and it’s way cheaper to buy. I am installing 72 solar panels on my house and I’ll never pay for another electric bill again. My hot tub will stay 101 with the eco spa 11, and my pool will stay 86 with the eco pool 27, and the ac will be running on all 4 units, both my Tesla’s will charge every day and I’ll never have to pay a penny in electricity again. So it all depends how you look at it. If you don’t have solar I’d think it’ll cost around 200 a month in electricity to operate it. But once again. 1/4 the cost of gas heater and no gas bill. So pick your poison and roll with it. So far I give this unit a solid 10/10.

5.0 out of 5 stars Works Awesome
Reviewed in the United States on September 13, 2020
The instructions are not great for pool heater so I wanted to explain how it works for people that are new to heater buying such as myself. I have an intex pool and actually spent more on this heater then the pool but I wanted to put my pool in my garage and see if it would work and it did. The heater is awesome. The heater does take 2 50 amps, the package says 40 and some things say 50, we used 50 and it works, if you are handy you can do it or you will need to hire an electrician, you cannot just plug this thing in. We spent about $200 on pvc pipe, wires and stuff to get this heater working so it will cost more then just the heater. We have a sandfilter and we are able to put it on N to make the heater run faster through the pump, when the heater runs through on filtration it does not run as fast. I hope the pictures help. It took an afternoon to get it all set up. Our heater would not turn on right away and it was because the flow was not fast enough.

1.0 out of 5 stars It works great for about 1 month - I'm on my 3rd unit
Reviewed in the United States on April 22, 2021
TERRIBLE DO NOT BUY.

They told me after the unit stopped working after 6 weeks that hard water caused a complete decay of the elements and that every 2 months I should have washed them. Well, if it stopped working after 6 weeks, then how is that even possible. They said the warranty doesn't cover hard water. I said that the elements are covered under warranty and she said "no" they aren't. They can't just "say" that. I asked them to prove it and show me where it says anything about hard water and she said it doesn't. They simply do not honor their own product.

Update again - My replacement has now stopped working. This elements inside are absolutely shot. They can't handle the chlorine.

Update: I got a replacement unit and this one works great!

I read the bad reviews, yet I still ordered this hoping it would work for me. It didn’t. The install was fairly easy as I had my electrician do it and my plumber. It worked great for two weeks. And then nothing. Then we go through the endless loop of terrible customer support. Customer support expects you to be a wizard at machinery. The flow meter is in the inlet and it is extremely difficult to take out and check and extremely difficult to put back in. After weeks of struggling with customer support inadequacy, she simply wanted to send me another flow meter, which was in perfect condition. I asked to speak with a supervisor and the lady said that she was going to tell me the same thing. I asked them to overnight the flowmeter because I have a short term rental business and this was going to cause a big problem for the weekend, and she said that I would have to pay for the overnight even though I spent weeks trying to solve this on the phone with them. I’ve had the unit for one month, end it is also already resting on the outside. I do not recommend this product. Beware.

Love this model , I have a very shaded back yard live in Canada my pool is 92f and its September. I hooked up only one breaker box .. professionally done, it says it ..requires 3... 50 amp breakers I have a 100amp service so that's not going to happen I have a 18ft round above ground approximately 8000 gallons this unit is rated for a pool almost 3 times its size. Parts were about $300 plus electrician. Easy fittings.. I spent very little on valves and couplers. It can be disconnected for the upcoming winter.. 3 wires, unscrew the unit and out bring in the house close the pool.. Keep it covered and protected its a digital face no Sun . I Use a deck box ..bottom cut out
