Pool Heating Systems


We’re engineered...for life.

- Beginning in 1977, we revolutionized solar pool heating by developing the world’s first collector with individual tubes. The advantages were immediately obvious; improved efficiency, unmatched wind resistance and better roof protection.

- Heliocol’s phenomenal wind resistance led to the first strapless mounting system. Other panels, which lift like a sail or an airplane wing in heavy winds, require multiple straps to hold the panel to the roof. Heliocol, on the other hand, is secured directly to the roof trusses with our patented Gator clamp. This mounting system is not only more stable, but requires significantly fewer penetrations into your roof.

- Heliocol was the first solar pool heating system to connect panels using a breakthrough plastic polymer clamp. Our patented panel clamp is a sophisticated replacement for old-style rubber hoses and metal clamps. Unlike rubber hoses, which can degrade and stain your roof, and metal clamps, which require regular rooftop service, our clamps offer the only maintenance-free solution.



The driving force behind Heliocol’s incomparable design is our team of exceptional research and development engineers. The technical and engineering expertise of our research staff, coupled with a relentless pursuit of continuous product improvement, has led to an impressive portfolio of registered innovative patents and intellectual property assets.

Overmolded Header

Heliocol’s patented overmolded header ensures the strongest possible connection between tubing because the header is actually formed around each individual tube.

One-piece construction eliminates welds and allows the collector to expand and contract with temperature changes.

The overmolded design also gives each individual tube full-flow access to the header, virtually eliminating backpressure and saving wear and tear on your pool pump.

Gator Clamps

Heliocol’s patented Gator clamp mounting system eliminates the need for straps, securing the panels with fewer roof penetrations.

The clamps also allow the headers to expand and contract with temperature variations, never cutting into the collector and never restricting water flow.

Gator clamps and Heliocol panels are engineered for maximum compatibility with each other and your roof. The Heliocol mounting system is designed to attach directly to your roof trusses.

Individual Tubes

Heliocol’s patented individual tube design resists lift, keeping the panels in place even in high winds.

The open design also protects the roof surface from rain rot, allowing rapid moisture evaporation.

Panel Clamps

Heliocol’s patented panel clamps replace old-style rubber hoses and metal clamps that require regular rooftop maintenance and replacement.

These durable, specially-engineered clamps never require replacement, never need to be tightened and, unlike rubber hoses, will not degrade and stain your roof over time.

Panel clamps allow panels to be mounted closer together for a more attractive and more efficient system with no wasted space.

Pipe Connectors

Heliocol’s CPVC pipe connectors provide more flexibility in installations. When a connection between panels is extended to accommodate obstructions on the roof, Heliocol’s pipe connectors work in conjunction with the panel clamps to provide a seamless, reliable coupling.

Heliocol is the most efficient solar pool heating system on the market, producing more heat per roof than any other system.

Part of Heliocol’s efficiency comes from its one-of-a-kind individual tube design. Not only do Heliocol’s individual tubes create more heat than other types of collectors, round tubes are the most efficient means of absorbing the sun’s energy. Heliocol’s patented individual tube design allows for maximum absorption of the sun’s heat all day long, unlike other panels which are most efficient only at solar noon.

Heliocol is also more efficient thanks to its flexible design and patented mounting system. Heliocol solar panels come in a wide variety of sizes and fit snugly on your rooftop, without unsightly gaps. With less wasted space, you can pack more power on every rooftop using Heliocol.


Heliocol’s modular sizing and variety of panel sizes allow the flexibility to custom fit any surface. Even PVC roof vents can be easily integrated--Heliocol’s individual tube design allows the system to open up and fit right over the vents.

Pitched shingle roofs, flat roofs, tile roofs...any roof with the appropriate sun exposure is suitable for a Heliocol installation.

If the roof isn’t a viable option, Heliocol is easily installed on ground racks, patios or fences. Because of Heliocol’s patented gapless design, the system also allows for more square footage in a smaller area, exceeding other collector brands by as much as 15 percent.

A site visit, can help you determine the most cost-effective and aesthetically pleasing installation option for your pool.


From backyard pools to the Summer Olympic Games, Heliocol’s proven reliability makes it the choice of smart swimming pool owners worldwide.

Heliocol’s trouble-free systems are completely resistant to pool chemicals, have an extremely low cost of operation and will work efficiently for decades.

Heliocol’s engineered design is unique among solar collectors, making it the most innovative solar pool heating system in the world.

Individual Tube Design

Heliocol’s one-of-a-kind individual tube design is one of the most significant reasons why Heliocol is the finest solar pool heating system on Earth. Most solar pool heating panels use a webbed tube design, meaning the tubes are connected together in a solid plate. Individual tubes are better for several reasons:

Individual Tubes Protect Your Roof and Prevent Roof Rot

Unlike webbed collectors, which trap debris and moisture, Heliocol panels allow your roof to breathe. Heliocol’s individual tube design allows for proper evaporation of rain and is the ONLY solar panel appropriate for flat roofs.

Individual Tubes Create More Heat than Other Panels

Round tubes are the most efficient means of absorbing the sun’s energy. Heliocol’s patented individual tube design allows for maximum absorption of the sun’s heat all day long unlike other panels, which are most efficient only at solar noon.

Individual Tubes Do Not Create Lift

Other solar panels use webbing between their tubes; this creates lift. To prevent their panels from flying away, our competitors must use straps to hold their panels in place. Straps mean more holes in your roof and greater potential for leaks. Heliocol solar panels create no lift and require no straps!

Gator Clamps

Heliocol’s patented Gator Clamp eliminates the need for straps and is the only mounting system that allows for natural expansion and contraction. This exclusive system eliminates tearing and pulling at the roof typical of glued systems. The Gator Clamp makes Heliocol the most roof-friendly system in the world.


Other manufacturers use rubber hoses and metal clamps to connect their panels together. The people of Heliocol have created the world’s only patented panel connector, the Plastic Panel Clamp. Rubber hoses require maintenance every six months and are prone to leaks and cracks. Metal clamps rust and stain the roof. Heliocol’s Plastic Panel Clamps never need maintenance, never rust and are guaranteed to never leak!

Overmolded Header

Every solar industry professional knows tubing connection is of crucial importance to prevent leakage over time. Heliocol’s patented over-molded header insures the strongest possible connection between tubing because the header is actually formed around the tubes. This process actually joins the tubes and header together as one solid piece.

You don’t have to be an Olympic athlete to swim like one!

The same Heliocol solar panels used to heat your backyard pool heat numerous high-profile commercial swimming pools, including those used in the Summer Olympic Games.

Although early Olympic swimming events were held in open water, the trials shifted to an early form of artificial swimming pool in the 1908 London Olympics. On the west side of White City Stadium, a 100-meter long swimming tank (twice the length of a modern Olympic pool) was constructed with a diving tower at one end and spectator stands surrounding it. The pool was unheated and unfiltered, leading one Australian swimmer to describe the consistency of the water as being \"as thick as pea soup.\"

Today, the Olympic standards for optimum temperature and water purity are strictly regulated, making the choice of solar pool heating system a critical concern for the Federation Internationale de Notation Amateur, the ruling agency that sets Olympic standards. After reviewing Heliocol’s stellar commercial performance record, excellent performance and unmatched reliability, the Summer Olympic Games selected Heliocol solar pool heating systems not once, but three times over, as the solar pool heating system of choice.

Heliocol Panels on the roof of the enclosed Georgia Tech swimming pool used in the 1996 Summer Olympic Games in Atlanta, Georgia

Beginning in 1996, Heliocol was chosen by the U.S. Department of Energy and the Summer Olympic Games to design and install the solar pool heating system to regulate the water temperature for the Olympic pool in Atlanta, Ga. In just a few short weeks, a 10,000-square-foot span of Heliocol solar panels was installed on the roof of the Georgia Tech Aquatic Center to cool and heat the million gallon pool.

The Athens Olympic Aquatic Centre

Heliocol was chosen not only for its reliability and cost-effectiveness, but for its accurate performance. The Federation Internationale de Notation Amateur requires that pool water temperatures be maintained at 26 degrees Celsius (79 degrees Fahrenheit) during Olympic competition, with only one degree Celsius fluctuation allowed from that standard. To maintain that temperature, Heliocol not only provided heat using free energy from the sun, but at night, the system was operated to radiate excess heat into the night sky, thereby cooling the water to the required temperature.

The Beijing National Aquatics Centre

Impressed by the solar system’s performance, Olympic officials selected Heliocol again in Athens, Greece in 2004. The panels were installed just prior to the competition, maintaining optimum temperatures throughout the 2004 Summer Olympic Games. Heliocol was selected as the solar pool heating system of choice yet again in 2008 for the Summer Olympic Games in Beijing, China.
