Eco-Saver Solar Pool Heater

I have this heater. Doesn't look like much but on a 15 ft. above ground it raises the temp. by about 10 degrees! My pool is 15' around with this heater is currently 84 degreesF and my sister in law's has no heater same pool and is 70 degrees! Takes up no space and is just so easy!

We have an above ground pool 15' we purchased three and it heated the pool wonderfully. Easy set up. Worth the purchase!!

Bought 2 of these last year, and hooked up in series. It does indeed raise the temperature - and quite quickly (10 degrees in 4 days)... Keep in mind that it needs to be able to receive sunlight most of the day. Also, you should bypass the heaters at night (or simply don't run your pool pump through the night) to avoid doing the opposite - losing heat through the solar heaters.... I have my bypass set to push 1/3 water through the heaters, and 2/3 straight back to the pool. Add a solar blanket to "keep" the heat in so you don't lose what you just gained.... Most users forget these simple steps - solar blanket to retain the heat, don't run the pump all night through the solar heaters, and try 2 in series (much faster to heat up) We will get many years out of this inexpensive method of getting into the pool earlier in the season and staying in the pool longer at the end of the season!

We bought one of these and it works.about as well as you would expect for the price. The smaller the pool, the better it works but the reality is that it has to be hot out for it to work and when its hot, your pool heats itself, so, it's ok overall, not spectacular.

We have had this 4 years to heat a 15 foot round above ground pool. It's very efficient in raising pool temp about 10 degrees on a hot sunny day. Must be turned on in morning when sun is hot and turned off when sun is off unit. We put it on a plastic table to catch as much sun as possible, make sure the blastic bubble is clear without things like dirt or grass clippings on it, and use a solar blanket when we're not in pool to hold hest in, in conjunction with it. Using both in this way, our 15 foot round pool gets up to 78 to 80 degrees F. We run unit from about 10 a.m. to 6 p.m. Can feel stream of warmed water coming in when sun is on it or ambient temperature warms unit. Cannot at heat at night as dark plastic gets energy from sun on it. This is passive solar technology, not intended to give results of electric high energy-use heaters, and cannot work like rooftop strips as does not have the square footage to collect energy. However, it is small, easy to set up, works great without leaking, does not require long hoses, and is cheap to buy and run with your regular pool filter. If your expectations are reasonable and it is used when sun on it, it heats a lot with little fuss and almost zero maintenance.
