I bought the solar heater and it came with the hoses needed to connect it to our intex pool.

Asked by Sunny101 June 27, 2019

We have an 18’ round above ground and have 2 of these heaters. Our yard and pool is extremely sunny and with a diverter (absolutely needed to slow down how fast the water travels through heaters) our pool is always in upper 80’s. If you don’t put the solar cover on during cooler nights you will lose anything you gained. With that said, your heaters MUST be in a very very sunny location as much of the day as possible or it’s pointless. They are solar heaters so they need to get super super hot in order to warm the water any. There is no power to these, it’s almost like when you leave some water in the hose and turn it back later on in the day and water comes out scorching hot...same concept here.

Pool is 18'x10'x48" 5000gal. Is this heater feasible?

Asked by Mikki July 8, 2018

This heater would be a great fit for your pool! Heater efficiency is determined by how many heaters are used simultaneously. In your case, 2 heaters would be an optimal fit, taking approximately 2 days to affect a 5 degree Fahrenheit change, opposed to 4-1/2 days with only one.

I have a 24 foot round pool, that is 52 inches deep. Aprox. 13,500 gallons. How many heaters sh...

Asked by eshaffer June 1, 2018

The amount of heaters needed will vary by preference. Adding more heaters will decrease the amount of time required to affect a change in your pool's temperature. Two heaters would be our recommended minimum, though you will find more efficiency with three or four. Please refer to our heater sizing chart for more details - http://www.poolmaster.com/wp-content/uploads/2015/09/59026SlimLineHeatingPerformanceChartDPHQP.pdf

I need for 8200 gallons of water above ground pool

Asked by Tj May 1, 2018

Hi Tj. You will most likely need several of these heaters to affect a noticeable change in a pool that large. I would recommend 3 units for your pool, but feel free to look at our performace chart to determine what works best for you. Here is the link - http://www.poolmaster.com/wp-content/uploads/2015/09/59026SlimLineHeatingPerformanceChartDPHQP.pdf

I have a 20,000 gallon pool what size solar heater do I need

Asked by Rebecca February 12, 2018

Hi Rebecca. This heater comes in one size - the effectivness depends on factors such as quantity installed, positioning, weather, and water surface exposure. For your size pool, it would be recommended to use at least two heaters, though three would be preferable. Be sure to use a pool cover during non-daylight hours to retain heat. Connection kits are available through Poolmaster, the manufacturer. Feel free to contact us with questions, or to order connection kits - (800) 854-1492 Also, please see our solar heater sizing and efficiency chart to make the best decision for your pool: http://www.poolmaster.com/wp-content/uploads/2015/09/59026SlimLineHeatingPerformanceChartDPHQP.pdf

Leaked and takes 3 solid days of sun to raise temperature 5 degrees. Pool wouldnt need heater with 2 solid days of sun. Also puts heavey strain on the pool’s pump which slows filtering and water circulation. Definately an ineffective and potentially problematic accessory.

I will give this a 3 star rating because it actually helps warm up the pool but it was so frustrating to put together. We had a few trips to home depot to get the correct diverter to fit the hoses. We bought 2 heaters and use a diverter in between. We enjoy our pool now.

Great IF......
This heater is amazing BUT there are a lot of variables you have to consider. We have an 18' round intex easy set pool 48" deep. The intex pumps are not the best but for some reason with 2 of these heaters the water pushes through very fast. With that said, you almost always should have a diverter (bought mine on Amazon) if you want the water to trickle and really heat up through the heaters OR have 3-4 heaters set up. Now it's about 77 outside and when I turned the pump back on (was off at night) the water that came out of the heaters was actually scolding hot! Again, because we only have 2 of these AND did not set up the diverter yet this lasts for a few minutes. When it's 77 out and end of August, I turn the pump on and off for a little while to let the water really heat up...every little spurt of scolding hot water helps keep the pool temp nice and warm. Also, do consider additional parts needed such as connectors for the heaters, if using multiples, as well as hose adapters for your size hose. I did not think the install was easy at all but now that it's set up I feel it was sort of common sense...I'm just not pool intuitive. If they go on sale I will buy 2 more along with 2 more connector kits.

Works well but had to buy an additional hose and clamp to hook it up. All in all, it does the job.
