How does Solar Pool Heating Work?

 

 

Solar pool heating systems usually have four basic components. The pump, the filter, solar collectors and a control valve. The pump takes the filtered water from the swimming pool or spa and sends it through the filter. The water goes from the filter to a flow control valve. The valve regulates how much water goes to the collector panels. If there is too much water flow going through the solar panels, the water will not heat as fast as it could. If the water travels slowly through the solar panels it will get really hot, then the hot water is mixed with pool or spa water, raising the water temperature. There are reports of “runaway” solar systems that have heated a pool over 100 degrees, so depending on the weather, your geographical location and the position of the swimming pool solar panels, you can get and keep your pool at your desired temperature. Solar heaters can also be used in conjunction with a conventional swimming pool heater, lowering heating costs by 60%-70%. The use of a solar blanket will double the efficiency of your solar pool heating system. Solar heating systems can also be used to COOL the pool or spa in certain geographical areas. If the pool is too warm, the solar system can be set to run during the night hours, and off during the daylight hours. This will lower the water temperature.

 

Care and Maintenance of Your Solar Pool Heating System 

 

Solar heating systems require very little maintenance. It is important to keep your water chemistry balanced and your filter in good operating condition. Since the water that goes into the solar collector comes straight from the filter, if there is anything that bypasses the filter, it can potentially clog the solar collector. Water chemistry is just as important. Improper pH and calcium hardness can cause mineral build up in the solar collectors, and can also cause the plastic to become brittle. It is a good idea to use scale inhibitor on a regular basis to prevent build up in the solar collector.

 

Winterizing Your Solar Heating System

 

Most solar heating systems have drain plugs to remove the water. It is also a good idea to blow air through the collector to remove any trapped water. This is also the best opportunity to inspect the collector panel for damage and inspect the mounting. Make sure the solar panels are secure and ready for the winter.

Liquid Solar Blanket

 

Tropical Fish Liquid Solar Blanket

 

A chemical with high molecular adhesion, Liquid Solar Blanket forms an invisible layer on top of the pool water surface. When the water is calm, the molecules form a barrier to heat loss. Although it doesn't heat the pool, it does retain the heat from the day, or heat put into the water from a gas or solar pool heater. For more information, please go to our Liquid Solar Blanket page.
