Gull Poly Pro Solar Collectors
 
Quality Construction
The Gull Poly Pro® is fabricated from a propylene copolymer with a stabilizer compound that provides long-term resistance to damage from heat and light. Large 2" manifold pipes made of the same materials are attached to a series of smaller distribution tubes using state-of-the-art thermal welding techniques. All hardware supplied to attach one collector to another and mount the collector to various roof materials is made of the highest quality stainless steel, rubber, nylon, and plastics available for outdoor use.
 
From a distance the Gull Poly Pro may look like other manufacturers' rectangular solar collectors. Many other collectors are solid mats that lie directly on your roofing material and allow moisture to be trapped beneath, causing fungus and dry rot. The Gull Poly Pro's unique design has slots cut between the collector tubes allowing air to circulate and your roof to breathe.
 
High Efficiency Design
The raised tube design exposes a higher radius of tube, trapping incoming light at different angles. A one-quarter inch gap between tubes allows for greater expansion and contraction of materials, basically an accordion effect, which helps increase the life of the collector. Open air flow slots between tubes allows the roof to breathe, preventing dry rot and lift of collectors in high wind conditions.

The Gull Poly Pro's extra large, Ultra-Flow 2 manifolds and anti-clogging, straight flow-through tubes provide superior circulation and improved flow that stops the collector from clogging and creates less strain on filter pumps. Greater flow equals faster heating and cleaning of your swimming pool. Less strain means longer pump life and lower energy costs.

Sizing
 
Some of the things you need to do before making an evaluation of the number of solar collectors required:

1. Measure the pool for surface square footage (length x width). Delete spa when making this calculation. The spa is heated on a separate basis, spa has a smaller capacity of water, when circulating spa only its turnover rate through the solar collectors is much quicker delivering higher temperatures at a faster rate.

2. Now that you have determined the square footage of the pool, check the sizing chart, below, to determine the minimum number of collectors.

Now that we've established base, evaluate what other factors may increase the size of the collector area to insure a good working system.

1. Does roof angle exceed 30 degrees? If so, add 10% more solar collector area per every 10 degree rise in angle away from 30 degrees.

2. If the pool is unusually deep. Note that all these sizing guidelines are based on 3' to 8' pool depths only. If depths exceed 8', add 10% more collector area per foot of additional depth.

3. What temperature range are you comfortable with? If additional temperature is required, add 10% coverage for each 2% of temperature above 82 degrees desired.

Remember that as the pool temperature exceeds the ambient temperature the heat losses of the pool surface will be greater making it more difficult to accomplish temperatures in the upper 80s or low 90s. A pool cover is recommended for this application to stop nighttime heat losses.

4. Is the pool shaded? If so, what percentage of the surface area is shaded and for how long throughout the day. When a pool is shaded it has two drawbacks that are detrimental to the performance of the solar system.

The pool loses its heat absorption gain from the sun.

The pool has heat losses of the surface due to the lower temperature in the shade.

If the pool is shaded, add amount of shaded area to the area of solar collectors required. FOR EXAMPLE: 25% of pool area is shaded, add 25% to the collector area. If the pool is shaded but for a limited time of the day, take the percentage of the day shaded X the area shaded and add to the collector area required. FOR EXAMPLE: 25% of pool shaded X 50% of the day = 12.5% additional panel area required. Pool covers are an advantage in more cases over increased panel area.

5. Is this an unusually high wind area (10-20 mph winds constant?) Loss of heat of the surface of the pool and the solar collectors due to high winds can be compared to the way a fan in a swamp cooler moves air across a water coil to cool down a room.

When sizing add 25 % more coverage to collector area and install a pool cover.

6. Is an extended pool season a requirement? If so, add 15% more collector area to extend the season from April to October. Because of the cooler night time temperatures in the months of April and October, use of a pool cover is a must to extend your swimming season.

7. When pipe runs exceed 100' from equipment to roof, add 5% more collector area.
