SWIMMING POOL: Who manufacturers solar pool heating & heaters? The List.

To many of you, the “remodel” you are presently doing may be a backyard and pool makeover project – and it is highly likely that you may be evaluating the different methods for heating that swimming pool oasis. GetWithGreen.com wants to reveal a list of top manufacturers of solar heating products to you. We want to make your quest to understand your options as easy as possible. Additionally, we want to make sure you have a place to double check the information you are receiving from your pool specialist or installer.

solar water pool 1How does a solar pool heating system work? A solar pool heating system works via black plastic panels or collectors capturing the energy from the sun and using it to heat the water in your pool. The materials used to make these systems are manufactured from high tech. plastics which have been designed to resist weather and resist the sun’s ultraviolet radiation. The materials are typically a flavor of polypropylene. Using your existing pool pump, water is circulated through the solar panels where it is heated by the sun and then returned to your pool. The collectors that sit on your roof typically come in the same sizes, no matter what manufacturer you get them from: 4ft x 8ft, 4ft x 10ft, or 4ft x 12ft.

Solar heating is not “on demand” heating. On demand heating? On demand heating is, “I feel like turning on the heater and heating my pool.” Solar pool heating systems doesn’t work that way. Solar systems heat only when water is running through those collectors, and when those collectors are being heated by sunshine – so your pool will not heat at night. But how well will solar heat your pool? FAFCO (collector manufacturer) says their systems will:

  • “raise you pool temp 2 to 5 degrees Fahrenheit each time the water passes through the system, and
  • raise your pool’s temperature 5 to 15 degree Fahrenheit over a period of several days of good weather.”

Do solar systems cost a lot? Solar, unlike electric or gas heaters, uses sunshine, and that sunshine is free – therefore there is no operating cost, and you are heating your oasis with a completely renewable, non-polluting, green, eco-friendly sourse. In addition, following the purchase cost ($2,500-$7,000), there are no ongoing associated utility bills. Here is some other cost and feature comparison between solar and other heaters:
