Solar blankets are frustrating to pull on and off the pool and pool heaters are expensive and run up the utility bill. So why not get a solar heater for your pool?
Overall, solar pool heaters work the same. Most have the following four parts:
- Solar Collector – pool water is circulated through the solar collector and is heated by the sun
- Filter – removes debris from the water before it is pumped through the solar collector
- Pump – moves water through the filter and collector and returns it back to the pool
- Flow Control Valve – either an automatic or a manual device that diverts water from the pool through the solar collector
To put it all together, pool water is pumped into the filter where debris is removed. The water then travels through the solar collector and is heated and then returned to the pool, thus increasing the pool’s temperature.
The flow control valve turns off if the temperature of the solar collector is similar to the pool temperature — filtered water bypasses the solar collector and is returned to the pool immediately.
- Eco-friendly since they use solar and not electricity.
- Less expensive than using a pool heater since solar pool heaters are generally less expensive and they don’t cost anything to run.
- Easier to use than a heavy solar blanket cover.
- Extends the months you can use the pool because it warms the pool up sooner and keeps it warmer for longer.
Before we get into the winners, we should note that how many solar heaters you need for your pool will vary by the solar pool panel you select and the size of your pool. It’s important to order the appropriate number of kits to make sure your pool is heated within a reasonable amount of time. The larger your pool, the more solar pool heaters it will need.
The solar sun rings are our #1 pick for best solar pool heater panels because customers rave about the increased temperature due to the use of these solar panels for pools. It is recommended that 70% to 80% of your pool be covered with these rings.
There are some complaints of the rings moving to one side of the pool due to wind, but if you cover 70% to 80% of your pool with these rings they shouldn’t shift much. The rings are five feet in diameter and are inflatable. They are lightweight, making them easy to remove and store during the pool off season.

Unlike our #1 pick, the SunHeater connects to the water pump and sits on the ground, not in the pool. It is compatible with existing pool pumps, and its patented design maximizes exposure to the sun’s rays. The SunHeater is a bit more complex to set up, but for a small investment, it may be worth the trouble this year if you plan to use it for more than one season.
This Smartpool solar powered pool heater is again different from our top two picks because it contains 80 square feet of solar panels which are mounted to the roof of your home, garage, shed, etc. This solar pool heater cost is more than our top two picks and it also requires a system kit, which has mounting and plumbing hardware.
The Amazon listing says it’s for in-ground pools only, but the description and customer reviews state it can be used for above ground pools as well. Overall, customers seem pleased with this pool solar heater but we found few people who have purchased it. We think it’s because of the high upfront cost and work, but if you’re comfortable spending this amount of money, we think you’ll be pleased with it.
Below you’ll find an alphabetical listing of other companies we’ve reviewed.
The Eco Saver solar heater for pool is similar to the Smartpool above. It can be used for above ground or in-ground pools. This Eco Saver solar pool heater has one 20 foot panel which can heat up a 24-foot round pool or a 15 by 30 foot rectangle/oval pool.
If your pool is a round pool up to 30 foot or a rectangle/oval pool 18 by 36 foot you will need two of these. Since the solar panel is so large, it is probably easiest to mount it on the roof of your home/garage/shed so it’s not an eye sore in your yard.
To mount it to the roof, you’ll need to purchase a separate kit. There are additional kits for the diverter valve and an Intex pool adapter.
This XtremepowerUS solar panel for pool system is similar to the Smartpool system. It has 40 square foot of solar panels which can be mounted on a roof or somewhere laying flat.
A diverter kit may be required for pumps greater than 1.5hp. You can find pool sizing and the number of these kits required on the Amazon listing page. This system didn’t make our top three because there are complaints about it not working well and breaking easily.
