I evaluated each product based on several key criteria. For solar covers, I looked at material thickness (mil rating), reported durability, and how effectively they claimed to retain heat and reduce water loss. For heat pumps, I considered their energy efficiency (like inverter technology), heating capacity for the specified pool size, ease of operation, and smart features. I also paid close attention to user reviews, looking for consistent feedback on performance, longevity, and overall customer satisfaction.
I deliberately excluded electric resistance heaters as they tend to be very energy-intensive and less cost-effective for heating an entire pool. I also didn't test long-term durability beyond initial impressions and reported user experiences.
Buying guide — what actually matters for best solar pool heater for above ground pool
Choosing the right solar pool heater for your above-ground pool boils down to a few crucial factors. It's not just about slapping a cover on; it's about finding the best fit for your pool and your goals.
Size and Shape
This might seem obvious, but getting the right size is paramount. A cover that's too small won’t effectively cover the water surface, meaning less trapped heat and more debris finding its way in. For round pools, measure the diameter precisely. For rectangular ones, measure both length and width.
Always aim for a cover that's slightly larger than your pool, as it's easier to trim excess than to deal with a cover that’s too short.
Material Thickness (Mil Rating)
For solar covers, the "mil" rating refers to their thickness. You’ll commonly see covers rated at 8 mil, 10 mil, 12 mil, or even higher. A thicker cover generally means greater durability, better insulation, and longer lifespan. While thinner covers are cheaper, they might tear more easily and offer less heat retention.
For above-ground pools, 10 to 12 mil is often a sweet spot for durability and effectiveness without becoming unmanageable.
Heat Retention vs. Algae Control
Solar covers work by trapping heat from the sun and reducing evaporation. However, they also block a significant amount of sunlight from reaching the water. If a cover blocks too much light, it can hinder photosynthesis for any algae that might be present, potentially leading to algae blooms. Many covers achieve a balance by being clear or tinted blue or black, allowing some light through while still absorbing solar energy efficiently.
Ease of Use and Storage
Consider how you’ll get the cover on and off your pool. Larger, thicker covers can be heavy and unwieldy. Many people opt for a pool cover roller system, which makes deploying and retracting the cover much easier. Think about where you'll store it when it's not in use; a dedicated storage bag or container can protect it from damage.
Type of Heater
While solar covers are the most common "solar" heater, there are other options. Heat pumps, like the AQUASTRONG model we discussed, actively heat the water using electricity. They are more effective at controlled temperatures and can operate day or night, but they require power and involve more complex installation. If you're looking for a simple, passive solution, stick with solar covers.
Frequently Asked Questions (FAQ)
How much can a solar pool cover actually heat my above ground pool?
On average, a good quality solar pool cover can raise the water temperature by 5 to 15 degrees Fahrenheit over a sunny period. The exact amount depends on several factors, including the size and type of cover, the intensity and duration of sunlight, ambient air temperature, and whether the pool is covered overnight. Aggregated user experiences suggest that a sustained sunny day can often make a noticeable difference, extending the swimming season into cooler parts of the year.
Is a solar cover really worth it for an above ground pool?
Yes, a solar cover is generally considered worth the investment for an above-ground pool. It provides a simple, eco-friendly, and cost-effective way to increase pool temperature without relying on electricity or gas heaters. Beyond heating, it significantly reduces water evaporation, which conserves water and helps maintain chemical balance, thus reducing the need for frequent chemical additions. Many buyers find the extended swimming season and reduced maintenance well worth the initial cost.
How do I properly install and maintain a solar pool cover?
To install a solar cover, simply float it on the surface of your pool with the bubble side down (or as per manufacturer instructions, as some blue-tinted covers may have a specific orientation). Ensure it covers as much of the water surface as possible. For maintenance, rinse the cover with fresh water periodically to remove debris and pool chemicals, and allow it to dry completely before storing it to prevent mold or mildew. Store it out of direct sunlight when not in use to prolong its life.
What's the difference between a solar cover and a solar heater?
A solar cover is essentially a passive solar heater. It's a material, usually made of polyethylene bubbles, that floats on the water's surface. Its primary functions are to trap the sun's heat, reduce heat loss through evaporation, and prevent debris from entering the pool. A dedicated solar pool heater, on the other hand, is a more active system, often involving collectors that use pumps to circulate pool water and heat it directly using solar energy, or a heat pump that uses electricity to transfer heat from the air to the water.
Will a blue solar cover heat my pool better than a clear one?
Blue and black solar covers are often designed to absorb more solar radiation than clear ones, which can translate to slightly higher temperatures. Clear covers, however, allow more sunlight to pass through to the water, which can help prevent algae growth. For most above-ground pools, a blue or a darker tinted cover usually offers a good compromise, providing decent heating while still allowing enough light to support water clarity and discourage algae.
Final verdict
For those looking to simply extend their swimming season and enjoy warmer water with minimal fuss, the Intex 28015E Solar Pool Cover is an outstanding choice, especially if you own an 18-foot Intex pool. It efficiently traps solar heat and reduces evaporation, offering a straightforward and effective solution at a great value.
If you need a robust option for a larger round pool, the In Swim 24' Standard Blue Round cover is a top-tier pick, offering durability and reliable performance. For those considering a more active heating solution that provides consistent warmth and advanced controls, the AQUASTRONG Inverter Swimming Pool Heat Pump stands out as a powerful and surprisingly budget-friendly option.
