Solar swimming-pool heaters are one of the most popular and most recognized use of solar-thermal energy today.  In the past, black-plastic tubing was used for solar pool heaters.  While this method absorbs heat to heat the pool water, it is prone to problems that cause headaches for pool owners, such as leaking systems and extra load on the pool pump.  With recent developments in high-efficiency solar vacuum tubes, pool owners can now invest in a heater that performs better and has a much-longer life expectancy.

Solar pool heating with evacuated tubes uses a heat exchanger to transfer the energy to the pool. This offers many benefits for the pool owner:

        The chlorine from the pool system does not come in contact with the heating system.  Chlorine is a harsh gas that damages most solar pool systems.  By using a closed heating loop, these new systems can last up to 20 years.

        Solar vacuum tubes are much more efficient than plastic pool heaters. 

        Vacuum tubes work in cloudy conditions and will provide heat to the pool even if the outside air temperature is lower than that of the pool water, which other solar heating systems cannot do.  Once the outside temperature drops below the pool temperature, other systems can actually decrease the pool temperature.

        Evacuated-tube systems also work in windy conditions.  This is great for regions that have a constant summer breeze.  Other solar pool heaters act like radiators; they blow off heat when it is windy outside.  A heating system that uses a vacuum-tube collector acts like a Thermos®, and is not affected by wind or temperature.

 

The following are a few examples of solar vacuum tubes:
