Question 1

What Is a Solar Pool Heater?

Accepted Answer

Solar pool heating systems involve pumping pool water through a series of tubes, known as solar collectors or solar absorbers, mounted on the ground or roofs of a building. The sun's free energy heat the circulating water, returning it backs to the pool at a higher temperature.

Solars pool heating systems work seamlessly with your pool equipment & are fully automated. You set the desired water temperatures on the controls of the solar. And when solar power is available at solar collectors.

An automatic motorized valve directs water through the solar panels and directs the solar heat back into the pool. This process continues until either the pool's filters pumps are turned off for the day or the desired pool temperature is reached.

In most cases, the existing filters pump can easily provide sufficient current to the solar panels. This is the time mosts pool professionals would recommend running your filters, whether you have solars or not. This is also the time when the pool is most likely to be used and is the time when good circulation is needed to clean the chemical distribution.

Question 2

How Does Solar Pool Heater Work?

Accepted Answer

Solar pool heater works by collecting fractions of this sunlight & use it to pump water from your swimming pool through your filter & back. Along with the ways, the water passes through a bunch of solar collectors, heating it. Solar pool collectors are made of different materials.

The types you'll need depends on your climate & how you want to use the collector. If you only use your pool when the temperature is above freezing, you will probably only need a glassless collector system. Unglazed collectors do not include glazing. They are typically made of heavy-duty rubber or plastic treated with an ultraviolet (UV) light blocker to extend the life of the panels.

Due to their cheap parts and simple design, glazed collectors are generally less expensive than glazed collectors. These unglazed systems can also work for indoor pools in cold climates if the system is designed to return to the pool when not in use.

Question 3

Working of a Solar Pool Heater:

Accepted Answer

Pool water is pumped to the collector. Before the water reaches the collector, it goes through a filter to remove any leaves, debris, and dirt. In a solar collector, the water is heated by the sun before being returned to the pool.

If you live in a warms climate area, the collector can be used to cool the pool during the summers months. This is possibles if you circulate water through the collectors at night.

Question 4

Tips to Improve:

Accepted Answer

Unglazed collectors are the best choice, as they are cost-effective and easy to install. Note that the type of collector you use in your pool greatly affects how effective your solar pool heater is. Now that you understand that unglazed pool heaters are unmatched when it comes to performance, let us now see how to buy the best solars pool heater.

Selecting the right collectors can be a daunting task but for best results, make sure you have selected the right heater. Most people buy the right solars pools heater, making the whole process a waste of time and money. To fix this problem, let us see how one should choose a solar pools heater.

Question 5

How to Select the Right Solar Pool Heater?

Accepted Answer

Buying a solars pool heaters can be an expensive exercise, considering that it can cost you between $3,000 and $4,000. Once you have a good solar heater installed, it offers payouts of up to 7 years depending on the quality of the solar & how it was installed, among other factors.

Before buying and installing any solar heating system, make sure you take note of the following.

Evaluate your site's solar resource:- It is an important consideration to bear in mind that the effectiveness of a solars pool heater depends on the amounts of solar energy reaching your pool.
Sizing Solar Pool Heater:- The size of a solar pool heating system is determined by several factors. For example, you need to consider the size of your pool, the length of the swimming seasons, collectors efficiency, desired pool temperatures, and average regional temperature.
Installing a solar pool heating system on a collector:- This is another major factor that must be considered whether the collectors should be mounted on roofs or anywhere near the pool for better orientation and exposure.
Checking Solar Pool Heater Efficiency:- One should also consider how efficient given heaters are before buying by checking the heater's thermal performances rating. A thermals performances rating is measured in either Btu (British Thermal Unit) or Megajoules (MJ) per square meter.

Question 6

Selecting a Solar Pool Heater:

Accepted Answer

A solar pool heating system typically costs between $3,000 and $4,000 to purchase and install. It offers payouts of between 1.5 to 7 years, depending on your local fuel cost. They generally last longer than gas and heat pump pool heaters. Your actual cost and payback depend on several factors. Therefore, before buying and installing a solar pool heating system, you should do the following:

Evaluate your site's solar resource
Set the correct system size
Determine the correct orientation and orientation for the collector
Determine system efficiency
Compare system costs
Check local codes, contracts, and regulations.

Question 7

Evaluating Your Site's Solar Resource:

Accepted Answer

Before purchasing and installing a solar pool heating system, you must first consider your site's solar resources. The efficiency & design of a solar pool heater depends on how much of the sun's energy reaches your building site.

Solars pool heating system uses both direct & diffused solar radiation. So, even if you don't live in a hot and sunny climate most of the time, such as the southwestern United States, your site may still have substantial solar resources.

Basically, if your building sites have unshaded areas & generally face south, it is a good candidate for a solars pool heating system. Your local solar system supplier or installers can perform a solar site analysis.

Question 8

Siting a Solar Pool Heating System's Collector:

Accepted Answer

Collectors can be mounted on rooftops or anywhere near swimming pools that provide proper exposure, orientation, and tilt towards the sun. Both the orientation & tilt of the collector will affect the performance of your solar pool heating system.

Your contractor should consider them when evaluating your site's solar resource and sizing your system. Solar pool heater collectors must be geographically oriented to maximize the amount of daily and seasonal solar power they receive.

In general, the optimal orientation for solars collectors in the Northern Hemispheres is true south. However, a recent study has shown that, depending on your location and collector inclination, your collector can withstand up to 45º east or west of true south without significantly reducing its performance.

Question 9

Determining the Efficiency of Solar Swimming Pool Heating System:

Accepted Answer

You can determine the efficiencies of solar swimming pools heating systems based on the thermal performance rating of the collector, if available. The thermal performance rating of a solar collector is measured by BTU (British Thermal Units) per squares feet per day: Btu/(ft2day) Or, the rating can be measured in megajoules (MJ) per squares meters per day: MJ/(M2day)

It can also be measured by BTU per day, which is the rating of BTU/(ft2day) multiplied by the area of ​​ft2. MJ per day is also used, which is the rating in MJ/(m2day) multiplied by the area in M2. The higher the number, the higher the solar energy collection efficiency.

Question 10

Comparing Solar Swimming Pool Heating System Costs:

Accepted Answer

before buying a solar pool heating system, you can estimate and compare the cost of using different solar collector models. This will help you determines the potentials cost savings of investing in a more efficient type of collectors, which may require fewer panels for the collectors' area needed to heat your pool.

To estimate and compares costs, you need to know the following:

Thermal performance rating of the collector (BTU/day)

The total number of collector panels or piping for the area required to heat your pool total installed cost of the system.

You can then calculate the collector's energy output per dollar spent or invests using this formula:

(BTU/day X # of collector panel/piping modules) Total installed cost of the system = BTU/$ per dollar spent

Example:

(27,900 X 4) BTU $3,000 = 37.20 BTU/day per dollars spent

If you know the collectors' prices and thermal performance ratings (BTU/day), you can use the following formula to calculates the energy output for each dollar spent or invested for different collectors:

BTU/Day Collector Value = BTU/Day Per Dollars Spent

Example:

21,000 BTU $387 = 54.26 BTU/day per dollars spent

Don't choose a solars pools heating system or collector based only on its estimated cost. When selecting a solar pool heater, it is also important to consider the size and design of the system and all the factors involved in the quality of the installation.
