My pool is 14 feet by 38 feet, how many solar mats do I need?

First off the mats are about 30" x 48", not the size that is advertised. If you live in a place that gets windy, they will blow out of your pool. Our pool deck is flagstone, so when the rings blew out of the pool and danced along the deck, they tore and deflated. Patches that are included with rings, do not hold up under summer heat and sun or at least not in S. Texas. But back to answering your question, start off with 4 or so and see if they are what you want.

2 is recommended. 1 for every 2 feet. I'm assuming your 75G is 48x18 footprint.

If you have 2 set of ladders on each side of the pool like I have, you might want 2 sets. One set for each ladder. If your Polaris only gets stuck on one side then one set. I have 2 sets. One set you get 2 panels. They do work. Sometimes the Polaris goes underneath the steps but nothing you can do. Get 2 sets. Then you'll be fine.

It covers like 12-14. Go about 3 ft wide and 4 long. Start your 4ft line about 6 inches behind back of the reflector

The mate size I ordered a mat that was 3 x 2" and found that I was really to small. If you do order the ladder you will find that the placement within the pool is the real key to the size of mat you will need. my mat fit just under the stair s width and extends about a foot on both sides. But can slide under the steps very eazy. I would recommend if you can find one about 4 x 4 this will allow you to locate the mate back up to the side wall of the pool and provide a good area on all sides for additional protection. Just an added note you might find out that you you have a little some gap between the ladder and the pool where a small mat will move around on you. Hope that helps.

I used 14 sections on a 27 ft round pool myself so i would say 12-13 but i do want to infrom you they are very cheaply made and i would not recommend this fencing because we installed ours this past fall and heavy winds have broken some sections please be aware of this before u waste your money.

I have a 12 mil solar cover and the Solar Roller works fine with that. My pool is small (13' x 26'). I cut the solar cover in half as instructed for the Solar Roller. They rollers do feel "flimsy" but they are durable. I rolled them up and hung them on ladder racks in the garage for the summer as I didn't need the cover. The key is not to bend the roller much and let the water pour out as you roll them up, prior to lifting them out of the pool and then carry them in the middle with both hands. It should weigh less than 30 lbs. I guess it could depend on the size your pool.

my pool is 20 x 40 with steps off to one side. It fit my pool. Really, even if a solar cover does not fit perfect you will still get a good effect from it. Its not like having to cover one for winter

Heating a 3500 gallon pool you should use the 18 or next one smaller. Heating a 35000 gallon pool you will need the 27. Keep in mind the electrical requirements. The 18 draws 150 amps. The 27 will require additional electricity that most homes are not wired for. Hope this helps.

Yep! We have an in-ground pool 12 x 20 and it helps to keep the pool heat in. If there's sun, it seems to help heat the pool as well.

You will need 2. But I will say that this has been THE BEST SOLAR LIGHT. I have bought several types and this is the best. It soaks up the light during the day and runs for about 6 hours at night.

More than enough, my pool is a 48" deep, 20' long x 12' wide oval. It was great all summer long, very low maintenance

One, if you want it to cover two sides you would need to buy two. We use it at our son's swim meets and just move it around as the sun hits different areas throughout the day.

Solar panels produce anywhere from 1000 to 2500 BTU's per square foot, per day depending on your climate, (northern, southern, mid). These panels are rated at 2 square feet, so 2000 to 5000 BTU's per day, depending on location. 1 BTU will heat one pound of water by 1 degree fahrenheit. A gallon of water weighs 8.33 lbs, so you would need 8 BTU's to heat 1 lb of 70 deg F water to 71 deg F. The water in your pool weighs 19,800 pounds. Just to raise the temperature of your pool water by 1 degree you would need at most 9 panels, or at minimum 4 panels. From your question it looks like you want to raise the temperature of your pool water from ambient 68(70) to 89(90)? That is a 20 degree delta T, so realistically you are looking at a 396,008(400,000) BTU load to keep your pool at 90 degrees during the summer,(which to me sounds wayyyyyy too hot for a pool). At best, producing 5000 BTU's per day from each solar panel you would need 80 of these panels to maintain temp. If you wanted your desire temp to be 80 deg F instead of 90 deg F than you would need 40. Someone correct me if I'm wrong. There are pool specific solar panels that might produce more BTU's per square foot of usable solar area. In my opinion, 80, or even 40 of these solar panels sounds a little unfeasible. Yes, you could do it, and it might be cheaper than purchasing a 400,000-500,000 BTU gas fired pool heater, but realistically it's not a good application for these specific panels. The common solar panel size to heat water for domestic hot water in households is an 8x4 which they rate for 40,000 BTU's. For those you would only need 10, but again might be a bad option, as they are large, and are quite expensive given their size, (usually 800-1400$/each). Hope this helps. PS. I am also not a pool expert. I am not sure on the thermal retention that pool water holds during the night. It could drop 1 degree in 10 hours or it could drop 10 degrees in 10 hours, I really don't know.

(2) sections of Kit C, and (8) sections of Kit A. Fits perfectly for a 24 ft. round pool. Hope this helps.

According to the product description it is for plaster/concrete pools and measures 14".

Im not really sure but our pool is 14ft wide and we had to roll at least two feet of net around the poles on each side for it to be tight, so about 20ft would be pretty close.
