In the 40+ years since the first polymer solar pool heaters were invented, there have been some great products and some not-so-great products. Though the sun has set on most of the not-so-great products, it’s still true that not all solar pool heaters are created equal.
Here are a few reasons why we think we’re better than the rest.
(Sunsaver & Sunsaver ST)
(Heliocol & SunStar)
Made in U.S.A.
ISO 9001:2008 Quality StandardsGlobally-recognized quality management standard.
Commercial Grade NSF-50 ListedMeets strict safety, durability, and toxicity standards
required by most states for commercial pool equipment.
IAPMO Performance CertifiedPerformance-rated and certified by the International Association of
Plumbing & Mechanical Officials (IAPMO) to SRCC Standard 100
TUBE & WEB
Round tubes joined by a center- or bottom-web and expansion joints.
Design allows for thermal expansion & contraction; extends service life
Web can be “vented” with slots or slits for wind-load and roof moisture relief
Multi-plate, thermally-welded and insert-molded construction
Direct, metered manifold delivers balanced flow through collector and prevents “hot-spots”
TUBE ON TUBE
Round (or square) tubes connected without any separation between.
Plagued by warping and buckling, which weakens collector and reduces lifespan
Monolithic design; poor wind-load & moisture relief
Design does not permit thermal expansion & contraction
Indirect, metered flow using secondary manifold/subplenum results in larger pressure drop
Sungrabber / Solar Bear
Techno-Solis (square tubes)
Individual tubes are held together with spacer bars; surrounded by air.
Exposed tubes lose heat faster to cool air
Loose tubes trap organic debris under collectors
Indirect, non-metered manifold causes unbalanced flow
Solar Pool Heaters Compared by Performance
Solar collector performance ratings are commonly expressed in BTUs Per Square Foot Per Day.
What this means, in other words, is how much heat energy (British Thermal Units, or BTUs) can be transferred to the heat transfer fluid (pool water, for example) per square foot of solar collector area, over a given time period.
Since collectors can come in many sizes, heat transfer per sq. ft. of collector area gives the best “apples-to-apples” comparison.
The following independent ratings are published by the Florida Solar Energy Center.
