Is a Solar Pool Water Heater Worth It?
You might have just completed constructing your pool, and you are wondering if installing a solar pool heater is a worthy investment. Investing in a solar pool heater is the best decision you can ever make as your means of heating water in your pool. A solar pool heater is not just cost-effective means of heating water in your pool but also the best way to conserve the environment.
Most environmentalist is encouraging people to start considering solar energy as an alternative to nonrenewable sources of energy. You will end up saving money that you would have otherwise spent on paying electricity bills, especially for those people who stay in regions where there are inflated electricity rates.
When Should I Turn on My Solar Pool Heater?
A solar pool heater should not be left on year round. There are times when you should turn it off or the water will be too hot for you to swim in. Depending on the region you are living in, it is advisable to turn on (usually by use of a manual diverting valve) your solar heater about 2-3 weeks before the cold season is ending and as it is approaching.
In our area, Southern PA, that means about the 2nd week in May, and Labor Day Weekend.
What is A Solar Pool Heater, And How Do They Work?
A solar pool heater is a device that uses thermal energy coming from the sun to warm pool water, just like photovoltaic panels, this kind of solar heater is mounted on the roof or along a section of “not used” ground.
A solar pool heater consists of the following items,
- Solar collector- a device where water is first circulated so that it can be heated by the sun
- Filter- that helps to remove the unwanted material from the water before it is pumped to via the collector (you typically already have this)
- Pump- which circulates water through the collector and filter, then back to your pool (you typically already have this)
- Control valve- that diverts water to or away from the solar collector

How The Solar Pool Heater Works
The working of a solar pool heater is not complicated; water is first pumped to through the filter to remove the debris and then through the collectors where the water is heated before it is directed back to the pool. During hot periods and climates, these collectors can be used to cool down the water temperatures by circulating water through it at night.
Modern solar pool heaters come with an automatic valve that is used to divert to the collectors when the collector’s temperatures are higher than the pool temperature. When there is no temperature difference between the pool water and the collectors, water will simply bypass the collectors and return to your pool.
Solar pool collectors are not the same; they vary in terms of the material used to make them and sizes; you should choose one that is suitable for how you want to use it and the climate you live.
The Solar Heater In Above Ground And In-ground Pools
Pools can be either above the ground or in the ground; for each type, you will be required to have a different kind of solar heater installation. Sometimes we are forced to go for above the ground pool due to lack of enough space to build an in-ground pool, but all of them work the same, but the above the ground pools work differently, given their large volume to the surface area, they have the capabilities of staying warmer than the in-ground pools.
Installing above the ground solar water heater is a simple process that involves cutting the return hose and then connecting it to the hose ends of the bypass kit. This is done so as to reduce the flow rate to the solar panels.
Installing in-ground pool solar heater is a bit tricky one; it requires some advanced planning to enable placement of 20’ or 10’ long solar panels and PVC plumbing to allow the water to move in and out of the solar panels.
How Much Do These Solar Pool Heaters Raise the Temperature of Water In a Pool?
The only challenge you will have when you are using solar energy is the time of sun shine. This is not the case for gas or electric pool heaters. The amount of energy produced by the sun is always constant, but we have stuff that gets in the way, variables such as weather, atmospheric conditions (like forest fires miles away), and randomness in water chemistry means there’s no perfect way to tell or predict how hot water will get for you.
The amount of water to surface area is another factor that determines how effective the heater in use is. panel heaters on a Sunny day tend to raise water temperature by about 10 to 15 degrees, but sometimes it can be more on a hot day, and less on an slightly overcast day.
How Many BTU Pool Heaters Do I Need?
The number of BTUs required mainly depends on the amount of water in your pool, 1 BTU will raise one pound of water temperature by approximately 1 degree Fahrenheit, one gallon contains 8.33 pounds, this means that if your swimming pool holds 20000gallons, you will be demanded to use 166,000 BTU in order to increase water temperature by one degree. You can further divide this number by twenty-four if you want to find out the amount of BTU you will be required to raise the pool water temperature by 1 degree for more than 24 hours.
There are a lot of questions that a solar pool buyer will have to ask themselves apart from the normal ones of knowing who the manufacture is. It is always recommended to buy a bigger one, the bigger, the better, a larger solar heater will heat your water faster than a small one, for example, a 300k BTU is likely to heater your water twice as a 150k BTU heater, but it will also burn gas twice.
Options to Consider Before Buying Solar Pool Heaters

Temperature and Functionality
If it is a leisure pool, then you need to keep it around 88 to 90 degrees, this may sound hot, but for water, it is not that hot, but if it in an exercise pool, then you have to get one to keep the water between 78 to 85 degrees.
How Much Should You Expect to Pay For a Top Solar Pool Heater?

Regular maintenance
Regular maintenance is essential for your heater if you want to last longer and get value for your money. This is mainly making sure your filter is always in good working order.
Use a pool blanket
A pool blanket is a useful extra to buy for your pool, and It allows the pool to retain the heat for a long time. Think of it like your mom telling you to wear a hat, because you lose all your body heat out of your head. The surface of the pool is expose to the air here and will transfer its heat to the cooler air.
Maintain proper water flow rate
If you want your pool heater to function well, then you have to ensure the flow of water to your pool is constant. Otherwise, the heater will not work well. Again this is mostly related to your filter functionality.
How to Install a Solar Pool Heater
Installing a solar pool heater is not a complicated process, follow this procedure
1. The first thing you have to do is to unbox your panels carefully and connect them together
2. Firmly secure the panels to your roof (or your planned location) using the provided hardware. Remember to attach the cross trap to hold down your panels in case of high winds.
3. Carefully cut the return pipe immediately after the filter and glue it on the check valve and the three-way diversion valve than is included in the solar heater control package.
4. On the opposite corner, connect another pipe directly opposite solar array, run it parallel to the top of the panels.
5. The next step is to run the exit pipe off the rack or roof towards the return line made in the third step.
6. Glue on one way valve before you connect the exit pipe into the return line so as to water from getting into the panel from the opposite direction.
7. The final step is to connect that exit pipe to the return line.
Types of Solar Pool Heaters
