The 4 Best Solar Pool Heaters 2022

A solar pool heater is an affordable and efficient solution to heat your swimming pool. But you have to check if the heater can generate enough heat to raise your pool temperature even during the winter season.

We all know that solar heaters work using solar panels. As solar panels receive less sunlight exposure during winter, they generate less heat. So, you need to get a heater that has more solar panels or bigger sized panels. This increases the heaters efficiency and helps it to generate enough heat to raise the water temperature.

Furthermore, an above ground pool requires a more efficient heater than an inground pool. This is because the heat escapes through the sides and top of an above ground pool. But, in an inground pool, the soil acts as insulation and does not let heat escape through the sides.

Below are the primary features you need to check while hunting for the perfect solar pool heater to heat your pool.

Apart from these primary factors, there are other several factors you need to consider that are mentioned in the Buying Guide.

But before that, you can go through our list of some of the Best Solar Pool Heaters to buy in 2022. We have considered different parameters and prepared the list to help you simplify the choice.

What Is A Solar Pool Heater

A solar pool heater is a type of heating device that harnesses the energy from the Sun to heat the water in your swimming pool. The water from the pool is forced across a special filter placed above the installed solar panels, which are either on the top construction or side of the swimming pool.

Solar heaters for the inground pool are the same as the traditional PV solar heaters. They have special pipes spread across the bottom surface of the swimming pool that ensure constant and uniform heating of the pool water. Many solar heating systems for swimming pools come with a special valve to control the flow, are equipped with sensors, and smartly operate, adjusting the temperature.

When you configure the temperature according to your needs, these sensors can measure the temperature of water generated from solar panels and adjust it according to your set value. If the water in the swimming pool is at a lower temperature, the heating device channelizes the water onto the solar collectors, which heat the temperature of this water. But when the water in the pool is warm or hot, the flow control valve switches off and reduces the amount of hot water being released into the pool.

Lastly, these pool solar panels are quite efficient, especially because the solar heating system is automated, and the process allows it to operate ideally and give you the desired output. So, you can enjoy a nice warm swim anytime you wish to.

The top is a smooth 1 1/2″ “Y” adapter with a 1 1/2 to 1/2″ threaded adapter in one side with a 1/2″ male to male threaded nipple to a 1/2″ ball valve and a 1/2″ threaded to ribbed adapter that the vinyl hose slides on. I used two hose clamps on each hose fitting to avoid leaks. Sand all smooth surfaces prior to gluing to assure a good seal. IMPORTANT: Do NOT glue any threaded parts. The glue will set long before you get the threads tight. Use Plumbers Grease or Pipe Dope to seal the threads. Even Teflon tape may leak due to the high pressure.

Winterizing Solar Pool Heaters

Getting your solar powered pool heater ready for winter is essential to preventing cracks or other damage during sub zero temperatures. Winterizing is relatively easy and can be carried out by a handy pool owner. The goal is to remove all water from the plumbing and collector panels and can be carried out during your regular pool winterizing or closing.

Allow water to drain from a low sitting drain, ball valve or check valve and if you suspect there is still water in the system, blow the water out with forced air. This can be done with a blower or compressor with attachment. If you aren’t comfortable doing this yourself we recommend contacting a pool service professional who is certified in pool closing and winterizing.

A solar powered pool heater will allow you to open your pool earlier and close it later and in some cases you will be able to enjoy your pool year round. In addition, you will save money in the long run and be doing your part to reduce environmental pollution.

According to Swim Universitys Three Quarters Rule, youll need enough solar collectors to cover about three quarters of the surface of your pool. For example, a standard pool size is 15 X 30 feet, or 450 square feet. Your solar collectors surface area would thus need to be around 338 square feet. However, if you plan to use your pool all year, youll probably want to plan on bumping up from three quarters to 100% coverage. For this example, you would need 450 square feet of available surface area to install your solar pool heaters on.

Is A Solar Heater Right For Your Pool

Unfortunately, solar heaters aren’t the right option for every pool owner. If you have a small pool that gets a lot of direct sunlight then a solar heater is a perfect solution for your heating concerns. However, pool owners with large pools or pools that are partially or fully shaded are unlikely to generate the amount of heat needed to make a difference.

Solar heaters use the sun to capture and replace heat for your pool that is naturally lost through evaporation and cooler temperatures. If you find that your pool is sometimes too cold to enjoy throughout the entire season and you are hesitant to spend the money on more expensive natural gas, propane or electric pool heaters then a solar heater may be a good option. Solar heaters are great for the environment and for your wallet. With the right conditions, they are extremely effective – some pool owners experience a 10° – 15° increase in pool water temperature.

Solar heaters and panels are simple to install and extremely versatile – they can usually be installed almost anywhere outside, including your home or shed roof, off your deck, beside your pool or even on the ground. Check your solar heater’s operating instructions for information about where and how to safely install it. .

Solar Pool Heater Vs Solar Pv Panels

Depending on your homes roof size, you may not have enough space to accommodate both a solar pool heater and solar panels to power your home. If this situation arises, youll need to do a cost-benefit analysis of which system will provide you with greater savings over time.

In general, wed recommend pairing an efficient electric pool heater and pump with your solar PV. That way, you can power everything with solar and will likely have the best savings. The added electrical needs from the electric pool heater and pump will add only 3-5 solar panels to the system, depending on panel wattage.

Our energy experts are ready to guide you through the rooftop solar process, and help you find the right option for your needs.
