Maybe you wanted to make an effort to go green, but most likely it was after seeing your pool heater’s first big gas bill. How it works, what’s it made of, and which is the best for your pool are things that remain a mystery to some pool owners. Well, never fear, we will give you the basics of solar pool heating.
What Is a Solar Heater?
The most common type of solar pool heater is an array of polypropylene (PP) veined mats that are spanned between two feed pipes. The mats, also called collectors, are laid out in direct sunlight to absorb its heat. As water is pumped through the mat’s veins, heat is transferred from the PP mat to the water. The water travels back to your pool to provide that cozy “chill-free” feeling in your pool.
A less common, but more expensive, type of solar heater is the glazed panel heater. These are aluminum-backed panels with copper piping sandwiched between tempered glass shields. Glazed solar panels are more efficient in transferring heat, but can be twice the price.
For above ground pool owners, there are less expensive lightweight options, like the Game Solar Pro, for heating your pool. These coiled packs of solar can be chained to heat rectangular pools that are up to 16’X32′ in size.
How to Size a Solar Heater?
To size a solar heater, you must first calculate the area of the pool’s surface. If you have a rectangular pool it is a simple length X width formula. However, for a Lagoon, or Kidney Shaped use online pool surface area formulas like the ones found here. In this example we will say our pool’s surface area is 500 square feet.
The solar heater panel array should equal 50-60 percent of your pool’s water surface area. In our example, we have a pool area of 500 square foot which means the required area of solar panels would be 250-300 square feet.
Whether a heater is gas or solar, do not be afraid to oversize it by going up to 70-80 percent of the pool area. The more panels there are to heat the water, the quicker your pool will get to your desired temperature.
Where Are You Going to Put It?
Before you buy a solar heater, make sure to scout the property for a reasonable place to install your panels. Be mindful of:
Unfortunately not everyone’s house has an unobstructed 8’ X 20’ roof section that faces true south. In those cases you will have to pick your position. Homeowners have laid out heater panels on the ground, decks, and have even hung them from a fence. Panels come with mounting kits so you can mount them to most structures that are sturdy enough to hold the panels plus the water they hold.
