How does a HELIOCOL Solar System Work?

How the Heliocol Swimming pool heating system worksA typical Heliocol Solar Pool Heating System is plumbed into existing pool plumbing.  Even if your system is not identical to the one shown, the illustration can help you understand the flow of water from the pool, through the pump, filter, solar system and back to the pool.
Notice that the union check valve is plumbed in after the filter. This prevents the filter from being backwashed by the water draining down from the panels when the pump shuts off.
Notice also that the 2-way valve either diverts the water to the solar system or directly back to the pool. It
Features a 5mm hole through the ball of the valve to enable water in the solar system to drain back to the pool when the pump shuts off.

  1. Using the existing circulation pump the water flows through the filter and then directed to the collectors.
  2. Check valve for preventing backwash of the filter when the collectors drain down.
  3. 2 Way valve that directs the water to the collectors when there is efficient sun radiation.
  4. Vacuum release valve for automatic draining of the panels after the solar system shuts off.
  5. Inlet to the solar panels at the lowest side of the bank, using the “reverse return” method.
  6. Outlet from the solar panels back to the pool.
