How To Choose The Best Solar Pool Heater For Inground Pools

It’s well-known that you can significantly reduce your pool’s heating costs by simply using a solar pool heater instead of gas pool heaters or pool heat pumps. So how do you select the solar pool heating system best for your type of pool?

First, you have to consider the size of your inground swimming pool. The primary question pool owners ask us is “how many solar panels are needed to heat an inground pool?“. A good rule of thumb is to get solar panel kits that are at least half of your pool’s surface area.

If you have a 20′ x 30′ pool, that’s 600 square feet of surface area. For this pool size, you need at least 300 square feet of solar panels.

Of course, there’s no stopping you from getting more than the recommended square feet. The more solar panel surface you have the easier it is you can heat your pool water, especially if you’re dealing with large gallons of water or you prefer swimming in water with warmer temperatures.

The next thing you have to consider is where will you place your solar pool heating system. For your chosen heating system to work, you need to place it in a location that gets at least 6 hours of direct sunlight.

The more time that your solar pool heater is exposed to harness the sun’s energy, the better. Some solar pool heaters can be easily installed on the ground and all you have to do is lay it there, others may have to be installed on your roof for better heat absorption.

Another you have to consider is the warranty of your solar pool heater. Manufacturers may offer warranties ranging from 2 to 10 years. This is vital in ensuring that you get the most out of your solar heating system.

Benefits Of Solar Pool Heating Systems

Environmentally-Friendly

Solar pool heaters do not emit any harmful elements or use any type of fuel, unlike gas pool heaters or any other pool heating methods. Once installed, there’s not much you have to do but use your pool and let the sun power your pool heating system for free without worrying about any bad impact on the environment.

Affordable Pool Heating

Unlike other types of pool heaters, solar-powered pool heating systems are not that expensive to install nor maintain. It’s one of the best features that you get to enjoy when you choose to use the sun’s energy to heat your swimming pool. You also get the chance to save money on pool heating costs.

Durable Heating System

Solar panels for inground pools undergo rigorous testing and inspection before they enter the market. This makes them one of the most durable pool heating options available today. Most panels are made from precompounded polypropylene that’s manufactured to withstand the harsh conditions on your roof and as well as the sun’s harmful UV rays.

FAQs About Solar Pool Heaters

How much do these solar pool heaters raise the temperature of water in a pool?

A properly-sized solar pool heater can add 15-20 degrees Fahrenheit to your pool water’s temperature for a better pool experience.

The more solar panels you are using the better the heat gain your pool can receive from your solar heating system.

What size solar pool heater do I need?

The size of the solar pool heater that you need heavily depends on the surface area of your swimming pool. It’s recommended that you get at least half of your pool’s surface area for your solar pool heater’s size.

For solar pool heater sizing, it’s always better to have more solar panels since it has low upfront costs than getting a gas pool heater or pool heat pump.

How to winterize the solar pool heater?

To winterize your solar pool heater, the water inside the collectors and piping system must be completely drained. You can either isolate each collector with a ball valve or you can switch the solar control to the “COLL” position if you have that option.

Once the winter season has passed, you can open the isolation valve in the collector feed line.

How long do solar pool heaters last?

Solar pool heaters are designed to last for several years, some may even last for more than 15 years. However, this may vary depending on the materials used to create the solar panels that you are using and where you place them.
