Free energy from the sun

More swim days, with no fuel bill.

A warm pool is a great gathering place for family and friends. A solar pool heater makes your pool warmer and more comfortable, and adds months to your swimming season. That means more relaxation, more exercise and more fun.

Unlike electricity, gas or propane, there is no charge for the sun's energy. Your system pays for itself through fuel savings compared with conventional heaters, and runs on a clean, renewable source.

No fuel bill

The sun does the heating, with no added gas or electric cost.

A longer swim season

Add months of comfortable swimming to every year.

Pays for itself

Fuel savings alone cover the system compared with gas or electric heaters.

Built as one piece

A solid, over-molded collector with no welds to weaken over time.

Smarter headers. Better absorbers.

Every collector combines a tube-on-fin absorber with an over-molded header in one solid unit, molded from a UV-protective polypropylene blend.

01  OVER-MOLDED HEADER

The header is injection-molded directly onto the absorber, forming a permanent, leak-free bond. One solid collector, with no welded seams to weaken over time.

02  BETTER FLOW

Generous 2" headers and straight-through flow keep pressure loss under 0.5 psi at 6 GPM. More flow means more heat for your pool and less strain on your filtration system.

03  TUBE-ON-FIN ABSORBER

A semi-selective surface absorbs 97% of the sun's energy. The fin lets the absorber flex with temperature changes and lifts the tubes off the roof to prevent abrasion.

04  MOVES WITH THE WEATHER

Flexible EPDM couplings and interlocking semi-dovetails let the array shift as temperatures change, preventing buckling and relieving stress on anchor points.

05  ANCHORED INTO THE RAFTERS

The 48"-wide collector lets mounts anchor into roof rafters, not just decking. Mounts hold the header off the roof to prevent moisture build-up.

06  BUILT-TO-LAST MOUNTS

Hi-Tec and SwimMaster Plus use three-part Universal Strap Anchor mounts in glass-filled polypropylene. iSwim and Nuvis use Type 302 stainless steel strap anchors. Both add wind-load strength across the array.

How it works

Simple, quiet and powered by the sun.
01

YOUR PUMP SENDS WATER UP

Your existing pool pump circulates water from the pool up to the collectors on your roof.**

02

THE SUN HEATS IT

As water flows through the absorber's tubes, its semi-selective surface captures the sun's heat and passes it to the water.

03

WARM WATER RETURNS

Solar-heated water flows back into your pool, adding comfort day after day.

04

LITTLE TO NO MAINTENANCE

No fuel to buy and no moving parts in the collector. The UV-screened polypropylene has proven itself for over twenty years, in all climates.

Bonus: cool your pool. In the hottest months, running water through the collectors at night releases heat and keeps the pool refreshing.
**Individual needs may vary. Check with your dealer to see if additional equipment is necessary.
