Buying Guide on Solar Pool Heater

What are the key features that you need to look for getting the best solar pool heater? These features will help you in narrowing the options and select the ideal one for your swimming pool.

Pool size 

It is necessary to the size of the swimming pool before you get the solar pool heater. A small pool will heat up with the small solar heater. 

However, for the bigger pool, you will need a large solar heater that can heat up the water efficiently.

Pool Type

Another point to keep in mind is pool type. Whether you have above ground pool or an in-ground pool. A small stand-alone solar heater will be enough for the above-ground swimming pool. Whereas, a large solar heater setup is needed for the bigger in-ground pool.

Temperature Rise

The third feature to look at is temperature rise. Every solar heater has the standard temperature hike it can provide (in addition to the swimming pool temperature). 

More solar panels result in more heat as well as more pricey. And fewer solar panels don’t provide heat. 

So always check with the manufacturer’s description before buying for the ideal temperature rise it can provide. Apart from that, it also depends on the climate, and pool size.

Mounting Type

You must remember there are three mounting types in the solar pool heaters: flat, racking, and on-roof. The Flat solar heater is like rolling a solar mat on the side of the pool. You can adjust the tilt of the racking mount type solar heater. 

The last one is the on-roof installation solar heater, it is one of the best solar heaters you can go for! Why? As it can provide you with efficient heating by consuming the maximum sunlight.

Needed Space

No matter what you choose, make sure you have a space to install it, otherwise, everything is a waste. A flat and racking solar heater will need space around the pool for installation, but that’s not the case for on-roof installation. Here you will only have to look at the available space on the roof for installation.

Installation Process

If you plan to DIY the installation, you must read all the instructions regarding it before you buy the product. What I would suggest is, go with the professionals for the installation process. Setting up solar panels, connecting them together, and making the heater work can be hectic.

Value for Money

Last but not least is value for money. You must buy everything, keeping this in mind. Solar heaters have a life of more than 15 years if maintained properly (more on it later). 

This won’t only let you enjoy swimming for extended seasons, but will also lessen your gas and electricity bills. 

So it is indeed a smart move, just look at the specification properly and make sure the brand or manufacturer is genuine.

Benefits of Using the Solar Heater for Pools

Above you read buying guide for pool solar heaters, here I am mentioning the benefits it will give you:

Extended Swimming Season

Heaters are meant to provide extended swimming seasons, and solar heaters do the same. There is a myth out there regarding solar heaters that they can’t work without sunlight. However, the fact is they can!

Saves Energy Costs

How? Solar pool heaters work on an infinite resource like sunlight. Hence it doesn’t require any other substance like gas or electricity which can get heavy on your pocket.


Another benefit of the solar heaters is that it is eco-friendly. With the increase in CO2 emissions, the environmental condition is degrading harshly. So it is necessary that we start using products that are less harmful to nature.

Little Maintenance

Just like other electrical equipment, solar heaters also need maintenance. The best point is the maintenance is very little (keep reading)!

Adds Value to the House

Among its many advantages, one is adding value to the house. As said, nowadays people are opting for more eco-friendly products, hence installing the one will certainly provide you monetary benefit as well.

If you have the solar pool heater already installed, it will act as a convincing agent for the buyer as in the future he won’t have to spend time selecting or installing the same. Think about it!

Disadvantages of Solar Pool Heater

Every coin has two sides. Just like that, this power-saving equipment also has some disadvantages. Though they are negligible you have full right to know about them.

High Initial Cost

This is something obvious! The solar heaters are indeed the costs for installing but that’s the initial cost. Once you have set up the heater, you will see a certain drop in your energy bills. In short, if you are spending somewhere, you are getting it back from the other source.

Requires Significant Space

Yes, you must look for the space to install the solar heaters. Electric and gas heaters are compact in size and can be mounted anywhere, but solar heaters require sunlight. So, they need to be laid out in the open ground or the roof.

Takes Much Time in Heating

Once you have installed the solar heater, it will take several days to provide the heightened heat to the swimming pool. Why? It doesn’t pull the power from your house and utilizes the naturally available. This results in low energy bills.

How to Take Care of Your Swimming Pool Solar Heater?

The most awaited section is here! No matter what equipment you get, it is necessary to take care of it properly. Just like electric and gas, solar pool heaters also require maintenance and taking care. Here are the few points that will help you out in the process:

Clean the Filter

You will have to clean the filters time-to-time, in order to keep the dirt and unwanted particles away from reaching the solar collectors. clean it once in a while, if you feel the filter needs to be changed, do it.


This is something that every solar heater owner should know. The solar panels are made of polypropylene (a type of plastic), which is tested to endure heat and withstand water pressure. The weak point of this equipment is freezing water, it causes much damage.

So, you must turn off the solar panels in freezing temperatures. This will extend its problem-free lifespan by a few years.

Touch Test

When you again start the heater after winterization, do the touch test. See if the solar panels are unusually warm, call the technician (if it is). The solar heaters are made to transfer the heat to the water flowing through them, which keeps it cool.

Install Solar Cover

The best hack to keep your pool warm throughout is by installing a solar cover. The solar cover will protect the water from evaporating in the summers and keep it warm in the winters. 

Install Bypass Valve

It can endure the water pressure but up to a certain level, so install the bypass valve to control the water pressure. If your pool pump is more than the maximum horsepower allowed, then a bypass valve is a must.


Do Solar Pool Heaters Work in Winters?

The solar pool heaters will work in the shining sun even if the atmosphere is cool. However, it also depends on which part of the world you are living in. In freezing northern winters, the pool solar heaters won’t provide much heat, where in eastern, western, or southern countries you will probably have solar heating available year-round.

Is Solar Pool Heating Worth It?

Yes, solar pool heating is worth it as compared to other counterparts of solar pool heaters – gas and electric heaters. It reduces the energy bills and does the work just like others.

What Is the Best Solar Pool Heater for Above Ground Pools?

There are many solar pool heaters for the above-ground pools but the Fafco solar bear pool heater is the best among all. Another option is SmartPool S220.

Do DIY Solar Pool Heaters Work?
