Solar Pool Heater FAQ
After reading our solar pool heater reviews, you now have a better idea about the best solar pool heaters you can find on the market, and why they’re worth your time and money, but you might still want some information about solar pool heaters.
With that in mind, here are some common questions regarding solar pool heaters so you can install them easily and start enjoying them right away.
Are they complicated to install?
Solar pool heaters don’t have to be difficult to install.
One of the reasons for this is that your pool system already has most of the elements you need, such as a pump, filter, and controller, as well as PVC pipes that direct the flow of water.
So, when you install a solar pool filter, you just need to break the PVC line and redirect it by running hoses to the solar collector panel.
This is basically what absorbs the sun’s heat, so you should try to position it in an area that gets the most direct sunlight. Good ideas are to put it on the ground in direct sunlight or on your roof.
Now, it’s important to know that your solar pool heater system has a heating component (which is the solar collector we’ve already mentioned) and the plumbing that’s required for it to work.
Once the collectors are mounted and installed, you’ll need to connect pipes to your pool’s pump as well as filter so that the pool water can move through the solar collectors, become warmer, and then get pumped back into your pool.
It’s worth noting that an in-ground solar pool heater will be a little more time-consuming to install as compared to an above-ground heater because you’ll obviously need to do some plumbing.
You might also have a higher number of solar panels that need to be connected in order for the heater to work.
As we’ve seen in this article, there are some above-ground solar pool heating systems that are really easy and convenient to use without the fuss.
An example is the Intex mat that can easily be put next to your pool to heat it up.
To install an above-ground solar heater, you’ll need to make sure you choose a location in your garden that will receive a minimum of six hours of sunlight every day.
Once you’ve settled on the perfect spot, you can connect the pump’s return hose into the inlet of the solar panel so that you can make water flow into the heater.
Then, connect this return hose from the solar panel outlet to the pool wall return so that the water will be warmed up by the heater and then flow back into the swimming pool, as In The Swim explains.
Do I need to use a pump?
A solar heater will need to be connected to your swimming pool pump to ensure that the pool’s water can be circulated through the heating system and become hotter as a result of moving through it.
This is why your pool pump is an essential part of the heating system!
In order for your pool’s water to be heated effectively, it needs to be directed to the solar heating system’s solar collectors.
When water moves through these collectors, it will be warmed up by the heat that the collectors have absorbed from the sun.
Then, the water can return to the pool and feel much warmer than it was before.
Can it heat the pool in winter?
Chances are that one of the biggest reasons why you want to install a pool solar heater is to make your pool nice and warm during the colder months.
If this is your main goal, then there are some important things to know about using solar pool heaters.
When you’re considering using your pool heater all through the cold months, it’s important to check the specifications of your specific heater.
Bear in mind that some solar pool heating systems require you to disconnect them and store them indoors for the winter.
An example is Fafco Solar Bear Economy Heating System for Above-Ground Pools that we featured in our reviews.
Doing this is important to prevent the solar heater from suffering damage in the cold winter months, and it’s something that quite a few solar systems will require you to do in order to maintain their quality.
Now that that’s out of the way, if you want to heat your pool through the winter you need to take your region’s weather into account.
As we’ve seen in our reviews of solar pool heaters, these products tend to warm up your pool by a few degrees.
So, if your region is warm throughout the year, a solar heating system will absorb lots of sun on a regular basis and this can be used to provide heat to your pool all through the year.
However, even if you use your solar pool heater during winter, such as if you live in a sunny region, you should invest in a pool blanket.
This is an essential item that can prevent the swimming pool water from experiencing a lot of evaporation, which can cause its temperature to take a dive during the winter months.
Solar blankets don’t only maintain the heat of the water but they also give your pool a bit of heat if there’s a lot of daily sunshine that they can absorb.
Conclusion
You love swimming but when the weather cools down it can force you to have to avoid using your swimming pool.
Investing in a solar pool heater system can change all that! It will extend the time that you have to enjoy your pool so that the swimming season doesn’t have to end.
If you’re interested in purchasing a solar pool heater, you’ll probably find one that tickles your fancy in our reviews of the best solar pool heater models on the market.
We’ve rated them according to their features, benefits, drawbacks and cost, so you can find the best one for your pool and lifestyle.
