Heating Capacity
The solar panels significantly increased the pool temperature from 74-76°F to 85-88°F, even with partial sun exposure.
Installation and Compatibility
Installation was manageable within a day, and quality is excellent with no leaks reported.
Efficiency
Custom installation using local hardware and an automated actuator system improved efficiency and saved costs.

The Smart Pool S601 Inground Pool Solar Heating System is a solid option for warming up your pool. Its polypropylene heat collector and 80 square feet of solar panels provide a significant heating capacity, potentially raising the water temperature by 6-10°F (4-6°C). This can be especially beneficial for those looking to extend their swimming season or simply enjoy a warmer pool.

The system's direct flow design, with one header hole for each heating tube, could enhance its efficiency by ensuring better water circulation through the panels. However, keep in mind that the installation kit is sold separately, which means additional expenses and the need for extra effort during installation. Compatibility with in-ground pools is a plus, but you should verify if it suits your specific pool setup.

Made from durable polypropylene, the panels are designed to withstand regular use and exposure to the elements, making them a reliable long-term investment. The unit’s dimensions (240 x 54 x 2 inches) and weight (34 pounds) suggest it’s a sizable system, so ensure you have adequate space for installation. Maintenance is expected to be straightforward, but periodic checks will help ensure the system's longevity and efficiency. It's a recommended choice for pool owners seeking an environmentally friendly and cost-effective way to heat their pool.

Heating Capacity
Installation and Compatibility
Durability and Materials

Most important from
38 reviews

Heating Capacity
The heating effect is moderate, raising water temperature by about 10.8°F, making it best suited for mild to moderately cool weather rather than very cold climates.
Installation and Compatibility
The system is well-built, easy to install, and works effectively when used smartly with proper flow and sunlight exposure.
Durability and Materials
The roll-up design and durable materials make it adaptable for various installation locations and outdoor conditions.
Efficiency
Running the panels only during sunny hours and using a solar cover helps achieve comfortable pool temperatures without extra costs.

The XtremepowerUS Universal Solar Panel Heating System is a practical option for Intex and similar above-ground or inground pools looking to extend their swimming season without extra utility costs. Its two 10-foot-long solar panels connect easily to create a fairly large collector area that captures sunlight efficiently, helping raise pool water temperature by around 10.8°F. This moderate heating boost makes it suitable for mild to moderately cool weather, though it won't replace a traditional heater in very cold climates.

Made from durable PE material, the panels withstand a wide temperature range and harsh outdoor conditions, which means they should last multiple seasons with proper care. Installation is flexible—the roll-up design and included connectors let you position the panels on the ground, roof, or an incline, but it requires a compatible water pump (not included) to circulate pool water through the system. Maintenance is straightforward since there are no electrical parts, just rinse occasionally to keep the tubes clear.

The heating effect depends heavily on good sunlight and proper pump setup, so effectiveness may vary. For those seeking a cost-effective, eco-friendly way to gently warm their pool and willing to handle some setup, this system offers a reliable solution.

Buying Guide for the Best Solar Heaters For Intex Pools

Choosing the right solar heater for your Intex pool can significantly enhance your swimming experience by extending the swimming season and maintaining a comfortable water temperature. Solar heaters are an eco-friendly and cost-effective way to heat your pool using the sun's energy. When selecting a solar heater, it's important to consider several key specifications to ensure you get the best fit for your pool size, location, and usage needs.
Heating CapacityHeating capacity refers to the amount of heat the solar heater can generate and transfer to your pool water. This is usually measured in BTUs (British Thermal Units) per hour. The higher the BTU rating, the more heat the heater can produce. For small to medium-sized pools, a lower BTU rating may suffice, while larger pools will require a higher BTU rating to effectively heat the water. Consider your pool size and desired temperature increase when choosing the heating capacity.
Collector AreaThe collector area is the surface area of the solar panels that capture sunlight to heat the pool water. A larger collector area can absorb more sunlight, thus providing more heat. For smaller pools, a smaller collector area may be adequate, but for larger pools, you will need a larger collector area to ensure efficient heating. Assess the available space for installing the solar panels and match it with the size of your pool to determine the appropriate collector area.
Installation and CompatibilityInstallation and compatibility refer to how easily the solar heater can be set up and whether it is compatible with your Intex pool. Some solar heaters are designed specifically for above-ground pools like Intex, making installation straightforward. Others may require additional fittings or modifications. Ensure that the solar heater you choose is compatible with your pool type and that you have the necessary tools and skills for installation. If not, consider seeking professional help.
Durability and MaterialsDurability and materials are important because they determine the lifespan and performance of the solar heater. Look for heaters made from high-quality, UV-resistant materials that can withstand exposure to the sun and harsh weather conditions. Durable materials will ensure that the heater lasts longer and performs efficiently over time. Consider the climate in your area and choose a solar heater that can endure the local weather conditions.
EfficiencyEfficiency refers to how effectively the solar heater converts sunlight into heat for your pool. Higher efficiency means more heat is generated with less sunlight. This is particularly important in areas with less consistent sunlight. Look for solar heaters with high efficiency ratings to ensure optimal performance. If you live in a region with abundant sunlight, efficiency may be less critical, but it is still a good indicator of overall performance.
Ease of Use and MaintenanceEase of use and maintenance are crucial for ensuring that your solar heater operates smoothly and lasts longer. Choose a solar heater that is easy to operate, with clear instructions and minimal maintenance requirements. Some models come with features like automatic temperature control and easy-to-clean surfaces. Consider your willingness and ability to perform regular maintenance when selecting a solar heater.
