How Does Solar Pool Heating Work?

Heat your pool using the Sun's free energy

A Thermal Solar Pool Heating system involves pumping pool water through a series of tubes, known as a Solar Collector – or Solar Absorber – mounted on the ground or roof of a building. The suns free energy heats the circulating water, returning it back to the pool at an elevated temperature. This heats the pool to a desirable level, as selected by the owner via the Digital Controller.

Solar Collectors are a crucial component to any Thermal Solar Pool Heating System. A Solar Collector works much like a garden hose left out in the sun, have you noticed that when you turn the tap back on, the water inside comes out warm or even hot? This is due to the hose tube absorbing the sun’s rays, and transferring this free heat into the remaining water inside the tube, just like a Solar Collector.

How Does Solar Pool Heating Work?

  1. The pool owner sets the desired pool temperature they wish to achieve on the systems digital controller (1).
  2. The digital controller will monitor both the roof sensor (2) and the pool sensor (3), and will turn the solar pump (4) on when the difference between the two sensors exceeds 7 to 8 degrees.
  3. The pump will continue to remain active, until the desired temperature is reached, providing that the solar conditions are favourable.
  4. The solar pump is responsible for collecting cooler water from the pool and pushing it onto the roof, and into the Solar Strip Collector tubes (5).
  5. The suns free energy heats the Solar Strip Collector; this heat is then transferred into the circulating pool water and back into the pool.
  6. The warming pool water then reaches the TufReturn manifolds (7), or the ProLok Loop returns (7) and continues to collect heat whilst being pushed back towards the return manifold and pipes (6).
  7. The now heated pool water is then returned back to the pool at an elevated temperature.
  8. When the pool sensor reads a temperature within 2˚C of your set temperature, the solar pump will turn off and the water will drain out of the solar system. This water is then replaced by air using the VacRel (Vacuum Relief Valve) (8) to avoid the collector tubes being sucked flat.
  9. This system not only has a low carbon footprint and initial set up cost, but will also satisfy most pool owners with its simplistic design and near zero maintenance costs, low running costs and its ability to dramatically increase your swimming season by up to six months. Relax, with a modern system, and enjoy the benefits of having a pool – more fun, fitness and entertainment for everyone.
