Richmond California has recently opened a community swimming pool that may be one of the most energy efficient in the country. They call it “The Plunge”. It is heated by solar collectors, it’s totally chlorine free and the building is heated by solar panels on the roof. The Plunge is an historic pool- it was first opened in 1926. Now after 10 years of renovations it has recently re opened August 14, 2010.
It’s a huge pool holding 324,000 gallons of water, and measures 60’ x 160’. The water is heated by circulating through eighty Heliodyne Gobi solar collectors on the roof.
Since the pool contains no chlorine, they use instead a saline solution combined with an ultraviolet disinfectant system. The use of natural ventilation and the reduction of chloramines in the water will make swimming in the Plunge a healthy experience.
The pool also has an array of solar electric panels that produce approximately 30 kilowatts for the building.
