GO GREEN with Solar Swimming Pool Heaters

Looking for ways to reduce heating costs and help the environment? Go for a solar heater. They are cost competitive with both gas and heat pump pool heaters and have low annual operating costs. How do they work? Most solar heaters include the following:

  • Solar Collector. The pool water is circulated through the collector to be heated by the sun.
  • Filter. This removes debris before water is pumped through the collector.
  • Pump. The pump circulates the water through the filter and the collector before it returns to the pool.
  • Flow Control Valve. This can be automatic or manual. It diverts water through the solar collector.

The water is first pumped through the filter then the collector, where it’s heated before returning to the pool. In hot climates, the solar heater can also be used to cool the pool by circulating water through the collector at night. When the collector temperature is similar to the pool temperature, the filtered water bypasses the collector and returns to the pool.
