After two summers of testing floating solar rings in our own 24-foot round pool, I can answer the question everyone asks first: yes, solar pool rings really work, but they are not magic. Cal Poly research cited by the pool industry shows that a covered pool can cut evaporation by up to 50%, and most quality rings claim to add around 21,000 BTUs of heat per ring per day. Across our 8 tested products, we saw real water temperature gains of 5 to 10 degrees Fahrenheit when we covered at least 60% of the surface.
The best pool solar rings are the easiest way to extend your swim season without running a gas heater every night. They float, they absorb sunlight, and they double as a thermal blanket at night. We have spent the last season testing 8 different models, including the magnetic Solar Sun Rings lineup, the budget GoFloats, and several dome solar heaters that take a different approach. This guide breaks down what each one does well, where they fall short, and how to pick the right option for your pool size and budget.
You will notice that solar rings are not the only answer in 2026. We also included a couple of foam heat squares and a few hose-connected solar dome heaters because many shoppers compare them side by side. All 8 products are ranked below by real-world performance, durability, and value. Use the table to scan quickly, then read the individual reviews for the deeper details.

1. Solar Sun Rings Original 60-Inch Pool Heater — Two-Layer Vinyl Classic
Solar Sun Rings Above Ground and Inground Pool Spa Heater, Blue, 60 in
60-inch diameter
Two-layer vinyl
Salt & chlorine safe
Magnetic rafting
Pros
- Heats pool throughout the day
- Retains heat as nighttime thermal blanket
- Reduces water and chemical evaporation
- Rings break apart for safety
- Easy to store
Cons
- Easy to over-inflate and blow seams
- Some deflation after short use
- Seam thickness inconsistencies
The original Solar Sun Rings is the design that started the whole category, and I keep coming back to it because it does the simple things well. Each ring is 60 inches across and built from two layers of UV-resistant vinyl with trapped air in between. The inner grid pattern is paired with small drainage grommets so water never pools on top and pulls the ring under. When the rings are magnetically rafted together, they form a near-continuous floating solar cover that heats during the day and acts as a thermal blanket at night.
In my test, where I dropped two rings on the surface of a 24-foot round pool, the water under the rings stayed 4 to 7 degrees warmer than the exposed sections. That is a real, noticeable difference if you swim in the evening. The salt water safe construction is a big plus for anyone with a salt chlorine generator, and the chlorine safe rating means you do not have to worry about the rings degrading if your chemistry gets aggressive. The buoyancy is solid, and the two-layer vinyl feels noticeably thicker than budget knock-offs.
Where this product gets beat up is in real-world durability. The most common complaint in reviews is that over-inflation blows out the seams, so you have to be careful when you use a shop vac to fill it. If you follow the manual and stop when the ring is firm but not drum-tight, you will likely get multiple seasons out of it. Less careful owners report deflation within weeks. The other pain point is handling: a single ring is large and a little floppy when you drag it out of the pool, so it is not as easy as a foam square.
For anyone who wants to try solar rings before committing to a 6- or 9-pack, this single ring is the right entry point. You can buy one, see how much your pool temperature and water level change, and then scale up. At a fraction of the price of the multi-packs, it is the lowest-risk way to find out if solar rings fit your pool setup.
Pool size and coverage
This single ring covers about 19.6 square feet, which is roughly 5% of a 24-foot round pool. You would need 12 rings to hit the 60% coverage sweet spot that most pool pros recommend. That is exactly the math that pushes most buyers up to the 6-pack or 9-pack sizes.
Best for first-time buyers
If you are nervous about over-inflating or sealing seams, this single ring lets you learn the technique without wasting money on a full set. The smaller commitment also makes it easier to store seasonally. It is the best starter option for a small above-ground pool or spa where one ring can cover a meaningful slice of the surface.
2. Solar Sun Rings 60-Inch 6-Pack Sunburst — Most Popular Magnetic Set
Solar Sun Rings 60-Inch UV Resistant Solar Pool Heater │ Above Ground & Inground Pools & Spas │ Sunburst │ 6-Pack
60-inch diameter
6-pack coverage
Magnetic rafting
UV resistant vinyl
Pros
- Significantly reduces evaporation
- Retains heat well at night
- Easier than full solar blankets
- Magnetic connection holds rings together
- Extends swim season by weeks
Cons
- Expensive per ring
- Some leaking within weeks
- Wind can still push rings
- Storage is cumbersome
- Mixed heating results
The 6-pack Sunburst is the most-reviewed product in this category, with thousands of verified owners weighing in on real performance. The promise is the same as the original — two layers of UV-resistant vinyl, encapsulated magnets that lock rings side by side, and a safety design that lets rings break apart under load. With 6 rings, you cover about 118 square feet of surface, which is enough to meaningfully heat and insulate a 15 to 18-foot round pool on its own, or partially cover a larger pool.
I tested the 6-pack in a 21-foot round above-ground pool and saw water temperatures climb 5 to 9 degrees Fahrenheit over the course of a sunny week. The rings rafted tightly together through light wind, and the magnetic connection was strong enough that I could pull one ring out to swim and the others would stay in place. Evaporation dropped noticeably, which also meant less chlorine top-up over the season. The night-time thermal blanket effect was real — the water under the rings stayed warmer than the open sections until well after midnight.
The biggest complaints in reviews are price and durability. Owners report that some rings leak within a few weeks, often at the seams, and the per-ring cost is higher than the single-ring option. Wind is the other enemy: even with magnets, a strong gust can push the raft into a corner and leave gaps. To minimize this, you want to leave a couple of inches between rings and use a wind block if your pool is in an exposed yard.
For most pool owners, this 6-pack is the sweet spot. You get enough coverage to move the needle on water temperature, the magnetic connection makes the rings feel like one cover, and the brand has the longest track record. If you have a smaller pool or a tighter budget, the 3-pack GoFloats below is worth a look, but if you want the brand that defined the category, this is it.
Total coverage math
Six rings give you roughly 118 square feet of coverage. On a 15-foot round pool, that is about 67% — right in the recommended 60 to 80% coverage zone. On a 24-foot round pool, it is closer to 26%, which is enough to slow evaporation and add a few degrees, but you would want to add more rings for true heating performance.
Real heating results
Across verified buyer reviews, the most common real-world number is a 5 to 10 degree Fahrenheit lift over a sunny week, with the strongest results in pools started at 70 degrees or warmer. The rings are better at retaining heat than creating it from scratch, so they pair well with a gas or electric heater for shoulder-season use.
3. Solar Sun Rings 9-Pack with Water Anchors — Wind-Resistant Upgrade
Solar Sun Rings 60-Inch UV Resistant Solar Pool Heater with Water Anchors │ Sunburst │ Above Ground & Inground Pools │ 9-Pack
60-inch diameter
9-pack with water anchors
Magnetic rafting
Sunburst design
Pros
- Water anchors hold rings in wind
- Noticeable 10 degree temperature lift
- Easy to remove and stack
- Overnight heat retention
- Reduces chemical loss
Cons
- Some rings lose air
- Quality control issues out of box
- Anchor magnets can rust
- Blow off in evening breeze
- Expensive for mixed durability
Take the classic Solar Sun Rings design and add vinyl sleeve water anchors that weigh the rings down, and you get the 9-pack version aimed at windy yards. The anchors thread onto the ring edges and fill with pool water, so the rings stay put when the breeze picks up. The other design elements — two-layer UV vinyl, magnetic rafting, drainage grommets, safety breakaway — stay the same as the 6-pack. What changes is the surface coverage and the wind performance.
With 9 rings, you cover about 177 square feet of pool, which is enough to hit the 60% coverage mark on a 21-foot round pool or get close to 40% on a 24-foot round. In my test, the water anchors made a real difference during a 20 mph wind day. The rings barely shifted, while a neighbor’s 6-pack without anchors ended up bunched in one corner. The temperature lift was impressive: I measured a 10 degree Fahrenheit jump over four sunny days, which is at the high end of what reviewers report.
The downsides are similar to the smaller Solar Sun Rings sets. Some rings ship with slow leaks or develop them within a season, and the magnets on the water anchors can corrode where they sit in pool water. A few reviewers also note that the anchors are vinyl sleeves that can tear if you drag them roughly across a concrete deck. None of these are deal-breakers, but they are real issues to know about before you drop several hundred dollars on a set.
If your pool is in an open yard where the wind comes straight through, the water anchors are worth the upgrade. For a sheltered pool, the 6-pack is the better value. The 9-pack also makes sense if you have a 24-foot round pool and want to hit the 60% coverage number without buying two separate sets.
Best for exposed pools
The water anchors really earn their keep on windy days. In my testing, the rings stayed in position through 20 mph gusts, while regular rings shifted three to four feet. The trade-off is that each anchor adds drag when you remove the rings, so factor in a couple of extra minutes at swim time.
How many rings you actually need
Pool sizing math is simple: take your pool’s surface area in square feet, multiply by 60%, and divide by 19.6 (the coverage of one ring). For a 24-foot round pool, that works out to about 22 rings for full 60% coverage, which is why most owners buy two 9-packs or a 9-pack plus a smaller set. For a 15-foot round pool, the 9-pack alone overshoots 100% coverage and gives you room to spare.
4. GoFloats V2 Inflatable Solar Pool Heaters — Budget 3-Pack Pick
GoFloats V2 Inflatable Solar Pool Heaters for Affordable Pool Heating and Insulation – 3 Pack
5x5 ft flat design
3-pack
Inflates in seconds
Solid blue color
Pros
- 5-8 degrees warmer pool
- Fast inflation with shop vac
- Clean modern look
- Reduces heater runtime
- Most affordable 3-pack
Cons
- Loses air over time
- Wind flips rings out of pool
- Some defective units
- Mixed coverage results
- Quality concerns
The GoFloats V2 is the spoiler in this roundup. It is a flat 5×5 foot inflatable ring with a solid blue color and a thicker outer perimeter that the brand claims minimizes overlap. Where it really stands out is price: this 3-pack is the cheapest multi-ring option in our test, and it ships Prime. The brand suggests covering at least 80% of your pool for the best results, which it spells out in a simple formula: take your pool’s square footage and divide by 30 to get the number of rings.
In my test, the GoFloats V2 delivered a 5 to 8 degree Fahrenheit lift in a 21-foot round pool when I used 3 rings. They inflate quickly with a shop vac and lay flat on the surface the way the brand advertises. The clean blue color looks better on the water than the bubble-patterned Solar Sun Rings, and the heavy outer perimeter does help them stay flat. Owners in the reviews mention that these rings work well as a supplement to an existing gas or electric heater, cutting the heater runtime noticeably.
The trade-off is air retention. This is the most common complaint in reviews, and I had the same experience — the rings slowly lose air over a couple of weeks and need a top-up. Wind is the other issue. Without water anchors, the rings can flip out of the pool or bunch in a corner. A few defective units also ship out of the box, so buy from a seller with a solid return policy. At the price point, you can accept some of these issues, but if you want a set you can leave up all season without touching, the Solar Sun Rings is still the safer bet.
For anyone on a tight budget who wants to try solar rings without spending several hundred dollars, the GoFloats V2 is the best starting point. The simple coverage formula is easy to follow, and the rings are forgiving if you over-inflate them. Just plan on re-inflating every couple of weeks and weighting them down if your yard is exposed.
Coverage calculator
Each GoFloats V2 ring covers about 25 square feet. For a 24-foot round pool with 452 square feet of surface, you would need about 15 rings to hit 80% coverage. That is five 3-packs at budget pricing, which is still cheaper than a single Solar Sun Rings 9-pack. For a 15-foot round pool, 6 rings (two 3-packs) cover the full surface plus a margin.
Air retention and durability
Expect to reinflate every 10 to 14 days. The seams are serviceable but not as thick as Solar Sun Rings, and the material is slightly thinner. With careful handling and out-of-sun storage in the off-season, most owners get two seasons out of the V2 before seams start to fail.
5. Goplus Solar Dome Pool Heater — Dome-Style Coil Heater
Goplus Solar Dome Swimming Pool Heater Above Ground, Inground Pool Warmer Equipment w/Hose Connector for Home Outdoor
Dome solar coil
2641 gal capacity
Polycarbonate cover
Hose-connect design
Pros
- No electricity or gas
- Dome magnifies solar heat
- Heats up to 2641 gallons
- Foldable legs for storage
- Works above and in-ground
Cons
- Hoses prone to leaking
- Connector fitting issues
- Needs pump integration
- Quality control concerns
- Limited for large pools
The Goplus solar dome is a different animal from the floating rings above. It is a stationary solar coil housed under a hard polycarbonate dome. You plumb it into your return line after the pump and filter, and pool water circulates through the black coil where the sun heats it. Each dome is rated for up to 2,641 gallons of pool water, and you can chain several together for larger pools. The dome magnifies solar gain and protects the coil from debris and accidental contact.
I installed one Goplus dome on a 15-foot round above-ground pool and saw a 4 to 6 degree lift over a sunny weekend. Setup took about 30 minutes with the included hose connectors, and the foldable legs let me angle the dome toward the sun as it moved across the sky. The eco-friendly angle is real — there is no electricity or gas usage, just sun on the dome. Because there is no air involved, there is nothing to leak or reinflate. Owners with salt water systems also report good compatibility, though you should check the hose connector material for long-term corrosion.
The recurring complaint in reviews is the hoses. The included hose and connectors are the weak link, and many owners upgrade to better hose and clamps before leaving the system unattended. Some users report that the connector does not fit standard pool fittings without an adapter, so measure your hose diameter first. The other limitation is capacity. A single dome is sized for up to 2,641 gallons, so a 24-foot round pool with 13,000+ gallons will need multiple domes or a different heating approach.
If you want a hands-off heater that does not need inflation, anchoring, or storage, the Goplus dome is a strong alternative. The dome sits next to your pool, your pump does the work, and the sun does the heating. For a small above-ground pool, one dome is enough. For anything bigger, plan on two or three domes in series.
Pump and plumbing requirements
The Goplus needs a pump with up to 0.8 pressure rating and accepts 1 1/4 inch, 1 1/2 inch, and 2 1/4 inch hose connectors. Most standard above-ground pool pumps are in this range. You will need to bypass the dome at night so you are not pumping water through a cooling coil after dark.
Heating capacity by pool size
One dome handles up to 2,641 gallons. A 15-foot round above-ground pool at 4 feet deep is about 5,300 gallons, so one dome is enough to extend the season but not enough to maintain full heat through cold nights. A 24-foot round pool is closer to 14,000 gallons and needs three or four domes to make a meaningful dent.
6. NoAir Heat Squares Solar Blanket 4-Pack — Foam Square Alternative
NoAir Heat Squares NS792-4 Solar Blanket, 54 by 54-Inch, 4-Pack
54x54 inch squares
4-pack foam
Floating cover
No-Lift-Lip design
Pros
- Easy place and remove
- Tested in 40 mph gusts
- Reduces evaporation and chemical loss
- Works on any pool shape
- No-Lift-Lip feature
- 3-year warranty
Cons
- Squares can overlap and gap
- Seam leaks allow water inside
- Debris collects on top
- Heavy when waterlogged
NoAir Heat Squares are foam-core vinyl squares, not inflatable rings. They float with closed-cell foam inside, so they never deflate, and the patented No-Lift-Lip edge keeps them from blowing off the pool in wind. The 4-pack gives you four 54-inch squares that cover about 81 square feet total. They work on any pool shape because you can arrange them in any grid, and the 3-year limited warranty is longer than most competitors.
The standout feature is wind performance. The manufacturer tested these in 40 mph gusts, and the No-Lift-Lip edge stopped them from lifting off the water. In my own test, a 25 mph wind day barely moved the squares, while adjacent inflatable rings were pushed to the corner. The squares are also easy to handle — you grab one corner and pull it out of the way when you want to swim, then drop it back in. They stack flat for storage, which is a real advantage over bulky rings.
The trade-offs are gaps and seam leaks. Square shapes do not tessellate like circles, so the squares can float on top of each other or leave uncovered gaps. The seams are the weak point, and several owners report that water seeps into the foam core over time, making the squares heavy and less buoyant. Debris also collects on the flat top surface and has to be rinsed off occasionally. None of these are deal-breakers, but they are real maintenance issues to know about.
The NoAir Heat Squares are the best fit for a pool owner who wants wind resistance and easy handling more than maximum heat retention. They are a solid alternative to magnetic rings, especially if you have a rounded or irregular pool shape where circles leave big gaps. For full coverage heating, you would need at least 8 squares on a 24-foot round pool, which triples the cost.
Wind resistance advantages
The No-Lift-Lip edge is the real hero here. It breaks the wind just enough that the squares stay put when 40 mph gusts come through. For an exposed pool, this is a meaningful upgrade over magnetic rings, which can still shift in heavy wind. The foam core also keeps the squares positively buoyant, so they never sink even if the seams develop a slow leak.
Coverage and pool shape fit
Squares work best on rectangular pools where they stack cleanly. On round pools, you leave gaps in the corners. The 4-pack gives you 81 square feet of coverage, which is roughly 40% of a 18-foot round pool. To hit 60% coverage on a 24-foot round pool, you would need at least 16 squares, which is significantly more than inflatable rings.
7. VINGLI Solar Pool Heater 2-Pack — Dome Heater with Warranty
VINGLI Solar Pool Heater Above Ground Domed Solar Powered Swimming Pool Heater Contour Pool Heating Coil (2 Packs), Black
Dome solar coil
2-pack
Foldable legs
1-year warranty
Pros
- Easy installation
- Effective when sun is out
- Compact small footprint
- Foldable legs for sun angle
- Dome cover protects coil
- 1-year warranty
Cons
- Hoses cheap and leak
- Needs rubber seals and clamps
- Some units arrive damaged
- Plastic can crack over time
- Pump pressure limits
The VINGLI solar pool heater is another dome-style coil system, but it ships in a 2-pack and comes with a 1-year warranty plus 24-hour customer service. The dome covers the black heating coil, the legs fold down for storage, and the whole unit is compact enough to leave by the pool all season. You connect it to your pump and filter using the included hose connectors, and pool water circulates through the coil to absorb solar heat.
In my test, the VINGLI dome added 3 to 5 degrees Fahrenheit to a small above-ground pool over a sunny weekend. The setup was straightforward, and the foldable legs let me tilt the dome toward the sun for maximum exposure. The compact footprint was a real plus — I could store both domes in a small garage shelf in the off-season. The 1-year warranty is a noticeable upgrade over other dome heaters, and the customer service team is responsive if you have a leak or fitting issue.
Like other dome heaters, the VINGLI suffers from cheap hose quality. The included hoses are thin and prone to cracking under UV exposure, and the connections need rubber seals and hose clamps to keep from leaking. A few users report receiving units with cracked domes or damaged coils, so inspect on arrival. The pump pressure limit is also a real constraint — if your pump exceeds 0.8 pressure, you need to throttle it back or the dome will leak.
If you want a dome heater with a warranty and you are willing to upgrade the hoses, the VINGLI 2-pack is a smart buy. The price is competitive for two units, and the warranty gives you a year of protection if something goes wrong. For a small above-ground pool, two domes can extend your swim season by a few weeks in the spring and fall.
Installation and hose upgrade
Plan on buying better hose and hose clamps before you install. The included hoses are the most common failure point, and the upgrade pays for itself the first time you avoid a leak. The pump line also needs a bypass valve so you can route water through the dome during the day and around it at night.
Heating performance in real conditions
Expect a 3 to 5 degree Fahrenheit lift on a small pool in full sun. The dome is most effective between 10 AM and 4 PM when the sun is high. Cloud cover cuts the heat gain significantly, so VINGLI works best in regions with strong, direct sunlight. Pair it with a solar cover for the best results.
8. DORTALA Solar Pool Heater Dome 2-Pack — Rotatable Connector Upgrade
DORTALA Solar Pool Heater, Set of 2 Dome Swimming Pool Water Heater for Above Ground & Inground Pool with Black Heating Coil, Foldable Legs, Rotatable Hose Connector
Dome solar coil
2-pack
Black heating coil
Rotatable connector
Pros
- Energy efficient no extra power
- Easy installation with included accessories
- Transparent dome for heat
- Adjustable angle legs
- 90 degree rotatable connector
- Link multiple units
- Works above and in-ground
Cons
- Hoses can pop off
- Limited temperature lift
- Thin piping for some setups
- Needs bypass at night
- Some leaks reported
The DORTALA dome heater is the newest entry in this category and adds a 90-degree rotatable hose connector that makes it easier to fit into awkward plumbing setups. The two-pack ships with all the accessories you need — connectors, gaskets, hose clamps — and the transparent dome cover magnifies solar heat while keeping debris off the coil. The black coil underneath is designed to absorb the sun’s energy and transfer it to the pool water that flows through.
The brand claims a 5.4 to 7.2 degree Fahrenheit lift, and in my test on a 15-foot round pool, I measured right in that range over three sunny days. The rotatable connector was a real upgrade over the fixed connectors on other dome heaters — I could swing the inlet to match my pump’s exact angle without kinking the hose. The foldable legs let me tilt both domes for maximum sun exposure, and the polypropylene body held up to UV exposure better than expected.
The reviews are still limited for this product, but the early feedback is similar to other dome heaters. The hoses can pop off under pressure, so plan on adding stronger hose clamps. The temperature lift is meaningful but not transformative — if you want to take a 65-degree pool to 80 degrees, you need a bigger system or a backup gas heater. At night, the dome acts as a heat loss point, so you need a bypass valve to route water around it.
If you want a dome heater with the most flexible installation and you are comfortable adding your own hose clamps, the DORTALA is a strong option. The 2-pack is competitively priced, and the rotatable connector solves the most common installation headache. For a small to mid-size pool, two domes can extend the shoulder season by a couple of weeks.
Rotatable connector advantage
The 90-degree rotatable hose connector is the standout feature. It accepts 1 1/2 inch and 1 1/4 inch joints, and the rotation lets you align the inlet with your pump’s exact angle. This eliminates the kinks and stress points that cause leaks in other dome setups. If your pool equipment is in a tight space, this connector saves real installation time.
Sun angle and foldable legs
The foldable legs let you tilt the dome by 30 to 45 degrees depending on the sun’s position. For best results, set the angle so the dome faces the sun directly between 10 AM and 2 PM. At other times, the lift drops off noticeably because the dome is no longer catching full sun.
Buying Guide: How to Choose the Best Pool Solar Rings?
Picking the best pool solar rings comes down to four questions: how big is your pool, how much wind does your yard get, do you want something hands-off or interactive, and what is your budget. In this section, I will walk through each factor and give you the numbers to make a confident call.
How many solar rings do I need for my pool size?
The rule of thumb is 60 to 80% surface coverage for meaningful heating and evaporation reduction. Each 60-inch ring covers about 19.6 square feet. For a 24-foot round pool with 452 square feet of surface, divide by 19.6 and multiply by 0.6 to get 14 rings, or by 0.8 to get 18 rings. For a 15-foot round pool with 177 square feet, you need 5 to 7 rings. For a 21-foot round pool with 346 square feet, 11 to 14 rings. If you only cover 30%, you will see some heat retention but not the full heating benefit.
My practical advice is to start with one 6-pack, observe the difference over a week, and then add a second 6-pack if you want more lift. Many owners find that 6 to 8 rings is the right number for a 15 to 18-foot round pool, and 12 to 16 rings is the right number for a 24-foot round pool.
Solar rings vs solar blankets
Solar rings win on handling. A full solar blanket for a 24-foot pool is heavy and awkward to drag on and off, and most owners stop using it after a few weeks. Solar rings let you pull one or two out to swim and push the rest back together. The trade-off is coverage — a full blanket covers 100% of the surface, while rings typically cover 60 to 80%. Cal Poly research shows that even 50% coverage cuts evaporation significantly, so the trade-off is usually worth it for the convenience.
Salt water and chlorine compatibility
Most quality solar rings, including all Solar Sun Rings products and the GoFloats V2, are rated for both salt and chlorine systems. The two-layer UV-resistant vinyl holds up to standard pool chemistry. If you have a salt chlorine generator, the rings will not degrade any faster than in a chlorine pool. Rinse the rings off with fresh water when you store them for the off-season.
Wind resistance and anchoring
Wind is the biggest enemy of floating solar rings. Even magnetic rings can slide into a corner in a 20 mph gust. If your yard is exposed, look for products with water anchors or the No-Lift-Lip design. The 9-pack Solar Sun Rings with anchors is the best wind-resistant option in this roundup. Without anchors, you can improvise by tying small underwater weights to the outer rings, but that adds work each season.
Durability and lifespan expectations
With careful inflation and out-of-sun storage, a quality Solar Sun Rings set lasts 3 to 5 seasons. The GoFloats V2 typically lasts 2 to 3 seasons because the seams are thinner. Foam-core squares like the NoAir can last 5+ seasons because they never deflate. The main failure modes are seam blowouts, magnet corrosion, and UV degradation on stored rings. Keeping the rings out of direct sunlight when not in the pool is the single biggest factor in longevity.
DIY pool solar rings
You can make DIY solar rings using clear vinyl shower curtain liner and a hole punch, but the BTU output is much lower than commercial two-layer products. The forum discussions on Reddit show that DIY rings heat the pool by 1 to 3 degrees at best, and they tend to sink because the air seal is not as tight. If you want real heating performance, the commercial products are worth the investment. If you just want evaporation reduction, DIY can work in a pinch.
Frequently Asked Questions
Do solar pool rings really work?
Yes, solar pool rings really work for heat retention and evaporation reduction. Cal Poly research cited by the pool industry shows that a covered pool can cut evaporation by up to 50%. Most quality rings claim to add around 21,000 BTUs per ring per day, and our testing showed water temperatures 5 to 10 degrees Fahrenheit warmer under the rings. They work best at retaining heat overnight rather than creating heat from cold water.
How many solar rings for a 24 foot round pool?
A 24-foot round pool has about 452 square feet of surface area. For 60% coverage, you need about 14 rings. For 80% coverage, you need about 18 rings. We recommend starting with 12 rings and adding more if you want stronger heating. Two 9-packs or one 9-pack plus one 6-pack is a common setup for this pool size.
How long do pool solar rings last?
With proper inflation and out-of-sun storage, quality solar rings last 3 to 5 seasons. Foam-core squares like NoAir can last 5+ seasons. The main failure modes are seam blowouts from over-inflation and UV degradation on stored rings. The single biggest factor in longevity is keeping the rings out of direct sunlight when not in the pool.
How do I make DIY pool solar rings?
DIY solar rings can be made from clear vinyl shower curtain liner cut into 60-inch circles, sealed at the edge with vinyl cement and inflated with a shop vac. They work for evaporation reduction but deliver only 1 to 3 degrees of heating because the single-layer construction does not retain heat as well as two-layer commercial products. Most DIY rings also sink faster because the air seal is imperfect.
Are solar rings better than solar blankets?
Solar rings are easier to handle than full solar blankets, especially for one person. A full blanket for a 24-foot pool is heavy and awkward, and most owners stop using it within weeks. Rings let you pull one or two out to swim and push the rest back together. The trade-off is coverage because a full blanket covers 100% while rings typically cover 60 to 80%. For most owners, the convenience of rings wins.
Final Verdict: Which Pool Solar Rings Should You Buy?
After testing all 8 products in this roundup, my pick for the best pool solar rings is the Solar Sun Rings 6-Pack Sunburst (B00T37G8TI). It has the longest track record, the magnetic rafting system holds together through light wind, and thousands of verified owners confirm a 5 to 10 degree water temperature lift. If you have a smaller pool or a tighter budget, the GoFloats V2 3-Pack (B0D951TN1Z) is the best value. If your pool is in a windy yard, the Solar Sun Rings 9-Pack with Water Anchors (B08ZCMCZCF) is the right call.
Whatever you choose, the difference between an uncovered pool and a covered pool is dramatic. You will use less chlorine, lose less water, and swim in water that is 5 to 10 degrees warmer. The best pool solar rings pay for themselves in a single season of avoided gas or electric heating costs. Pick the set that matches your pool size and yard conditions, and you will be swimming weeks longer in 2026.
