  • ATTRACTIVE BLUE DESIGN - Sun2Solar solar blankets are made from a film of thousands of tiny bubbles, which work together to collect and retain heat both at night and on those chilly days. The blue color provides an appealing look while also using the sun’s rays to help warm your swimming pool.
  • MINIMIZE WATER EVAPORATION - The use of a solar cover helps in preventing up to 95% of pool water evaporation. When not enjoying a refreshing swim, keeping your pool covered lessens the vast amount of water lost into the environment. Fill up your swimming pool less and enjoy it more!
  • JUMP INTO WARMTH - Show friends and family your bravery by jumping in without the standard toe dip. Enter the swimming pool confidently knowing the Sun2Solar solar cover has kept the water warm just for you. It’s easy to put on and take off allowing more time for showing off.
  • HEAT RETENTION - After everyone has called it a day with wrinkled fingers from too much fun in the sun, make sure to place this solar cover back atop the water. Don’t lose all of that warmth generated throughout the day when the sun sets. Assure your pool’s temperature does not drop too much by protecting it at night through use of a solar blanket.
  • TRIM TO FIT - Your pool may be uniquely shaped and getting the right fit is as easy as finding a marker and sharp pair of scissors. Have the bubbles facing down to the water and trace a line on the cover showing where you should cut off the additional material. Do so confidently knowing this won’t affect the manufacturer’s warranty---they understand.

How to Install a Solar Heater in Your Pool

The simplest and least expensive way to warm an unheated pool is through a solar panel.

By preventing evaporation (which can account for up to 55 percent of a pool's heat loss) while still permitting sunlight to warm the wa­ter, a plastic cover can raise the tempera­ture of a pool by as much as 10° F. on a sunny day. Used in conjunction with a conventional heater, a pool blanket can pay for itself over a single season in re­duced energy bills.

But full-fledged solar systems, available from solar equipment-dealers and from some pool-supply stores, are even more effective. Most pools are heated to around 80° F; in warm weather, a solar system can do the job unaided by a stan­dard gas or electric heater. In cooler weather it can save considerable energy by preheating the water before it passes into the conventional heater.

Because the basic plumbing necessary to circulate the water through the solar collector panels is already included in the pool's filter system, a solar heating loop need only tap into the existing pipes- usually at a point just beyond the filter but before the conventional heater, if any.

A one-way check valve prevents wa­ter from draining back into the filter from the elevated collectors, and a manual or thermostatically-controlled gate valve al­lows pool water to bypass the solar heat­er on cloudy days, or whenever the pool has heated up sufficiently. The existing swimming-pool pump will often be pow­erful enough to circulate water through the panels, but the panel manufacturer or dealer may recommend that you retro­fit a larger pump.

Solar collector panels for pool heat­ing are simpler and lighter than the ones that are designed for hot-water sys­tems, requiring no insulation or glazing. Many are copper; others are merely 3-by-8-foot sheets of molded plastic, honey­combed with channels through which the water circulates.

The panels must be mounted on a roof and oriented toward the sun in the same manner as other solar collectors. If near­by south-facing roof surfaces do not pro­vide the proper angle, you can secure the panels to an inclined roof rack, but covered with %-inch plywood (the lightweight pool panels will sag in the middle if they are not supported). In many cases, however, the simplest way to mount the collectors is to build a nearby cabana-style shelter with its roof oriented due south and pitched at an angle equal­ing your latitude.

To heat the water adequately, you will need collector panels with a total surface area equal to half the area of your pool. To ease installation, use schedule-40 PVC pipe and, whenever possible, PVC valves and fittings to make the plumbing con­nections. Buy the type of pipe that is specifically labeled for outdoor use; the plastic is formulated with a stabilizer that enables it to withstand prolonged expo­sure to sunlight. The PVC pipe ordinarily used for indoor plumbing degrades rap­idly in the sun and must be painted if it is used outside the house. You can buy pipe, fittings, and any other hardware not included with the panels, at plumbing and home-improvement stores.
