Exact Solar

Solar swimming pool heating is the most affordable, efficient and cost effective means of harnessing and utilizing solar energy.  

Solar pool heating panels reduce your heating bills and increase your swimming season, resulting in greater enjoyment of your swimming pool.

The Department of Energy has a good overview.

Solar pool heating is uncomplicated and reliable.  A properly sized solar pool heater will raise the temperature of the water 10 to 15 degrees.

In order to capture the sun's energy, an area large enough to mount the collectors is necessary.  This is typically a roof or a rack custom built for the collectors.  The collector area necessary is 50% - 60% of the surface area of the pool.

Costs of solar pool heating solutions vary greatly depending on the size of the pool and difficulty of installation but usually range from $3000 to $5000.  If you currently use gas or propane to heat your pool, a solar pool heater could pay for itself in as little as 2 years.

1. Water comes from the pool and flows through the pump and filter as usual.  In most systems, the existing pool pump is sufficient.
2. Temperature sensors measure the temperatures of the water and where the solar collectors are mounted.  Solar collectors are typically mounted on a roof or a rack built for them.
3. When the temperature of the collectors is higher than the water, the automatic control turns the 3 way valve and sends the water to the solar collectors to be warmed by the sun.
4. If the temperature of the collectors is lower than the water or if the water has already reached the maximum temperature you have selected, the automatic contol bypasses the solar collectors and sends the water back to the pool.
   

To increase the efficiency of collecting the heat, solar collectors are design to maximize the amount of energy collected and are designed to last 15-20 years.
