Heats the pool nicely. I have a 16k gallon pool. Noticable difference within a few days. Instructions aren't as descriptive as they should be. I plumbed 1 1/2" from my filter up to the collectors and back. This created a pressure/flow problem. A week later, tore it all out and replaced with 2". Problem fixed. The check valve that came with the kit was defective. Check all parts for working order before installing. I get a 10 psi rise when I route the water through the collectors. System running good with a 1 1/2 hp pump

installation instructions are weak, so here are some pictures of what I did with some Homedepot help.

OK, here is a great invention with a product handled by a terrific company. Smart Pool.
THE FACTS: I live in Miami Florida and yes it is hot here in the summer however my pool has a lot of landscape and palms around it which provides shade to about 2/3 of the pool so my pool water rarely gets to the desirable temperature it normally stays between 82 to 85 in the summer while the temperature outside is 91 to 95. we like the water in between 88 and 90 especially those days when we use it in the evening and into the night.

THE PROCESS: My pool holds about 12,000 gals of water so as per their chart I needed two boxes (4 panels) but I went ahead and ordered 3 boxes (6 panels). I installed it myself with the help of my two sons and took us a few hours. I ran the piping myself as well. at the first try it didn't work - there was too much pressure on the pump and there was not enough flow to run the jets so I contacted the Company directly (Smart pool) and this is the part that gets really good.

THE COMPANY: Their customer service was great; it exceeded my expectations. They took all the necessary time on the phone to review the installation I had done, the layout, etc. we even traded pictures over the email so they consulted with their experts and came back with recommendations including changing the configuration of the piping connecting to the pool pump and worked with me all the way through until it was resolved. Kudos to this company for their superb Customer Service.

THE PRODUCT: I am Completely satisfied with this product. it is a great invention and works well - easy to install. I was expecting to raise the temperature of my pool water by 4 to 5 degrees and to my surprise it went from 86 to 93 by the the second day. I hope I can extend my summer a month or two here in Florida with this Sunheater. BTW: the water stays warm at night as well it only cools down 1 to 2 degrees through the night.
We are enjoying it!

I have had this on my roof now for a couple of months and it does heat the water. I have 4 on my roof for a 16X30 oval inground pool. It will push out noticeably warm water. We got to use our pool much more at the start of the season than last year. However, I'm not sure the trouble of installing/maintaining and the damage it does to the roof to install it is worth it.

When you take these out of the box they are coiled up so tight it will take two people a lot of work to get them unrolled. We did this early spring when the temps were in the 50s and they did not want to flatten out at all, even in direct sun! We had to weave them through a plastic fence so the bends would start to smooth out over the course of a couple days. It wasnt until they installed on the roof in warm temps that they flattened out.

Obviously you will have to put holes in your roof to install the brackets for this, so be sure to seal them up good. I did not buy their installation kit based off of the reviews. I bough everything from home depot. What is lousy is that they give you almost all the brackets you need with the solar panels, but leave out some to force you to buy more. I have yet to find where I can purchase just the missing brackets.

Since the only thing securing the panels is nylon rope over the panels themselves, the pipes can move around. I have noticed that this is causing them to wear through my shingles either from wind or expansion/contraction when hot and cold. Either way, it is something I now have to fix.

Mine has a section of one of the panels that will not flow water. Because of this that sections stays hot while the sections around it become cool when water flows through. So the hot sections becomes warped and unsightly. I contacted their support who told me to disconnect the panel and look for baffles that could have been installed on accident. This is not easy to do once it is installed obviously, and there were no baffles in it. Depending on what they do when I call them back will determine the final rating of this review.

YES! This product RULES!!!! We were skeptical, but after pricing a pool supply company installing solar ($3500 or more) we decided to take the risk and buy this product.

Our pool is almost 17k gallons. The SmartPool website recommended 3 boxes with an extra box to extend you swim time. We bought 4 boxes, which was a total of 8 panels that are 20' X 2'.

When I was installing the panels it was almost 90 degrees, which made it like 120 on the roof, ugh! Then immediately after installing it rained for 3 days, ggggrrrrr! Once the clouds went away and the sun came out the temperature of our pool shot WAY up. We are in Sacramento CA and our pool has a very light colored surface plus the neighbor's trees block the sun from half of our pool. We usually swim July to August. We were swimming the first week of May! Our pool is maintaining at 82 - 90 degrees with the outdoor temp in the high 80's. We lose about 6 degrees at night; however, we opted to not use a solar cover for safety reasons. By the early afternoon the pool has gained back whatever it lost over night.

We have a single story and we are using a Pentair Intelliflo pool pump running at 2300 rpm's from 9am - 7pm. We have not really noticed a jump in the electricity bill, the pool cost us approximately $16 - $25 a month in electricity.

If you are like me, in your 40's and no longer wish to swim in water unless it feels like you are in a tropical paradise, then buy this item. Go big, get an extra set of panels.

I also order the WWSK21 Kit, which I reviewed. I was not impressed with the value of the kit.
