What is Solar pool heating and how does it work?
Solar pool heating is a method to increase the temperature of swimming pool water by using the sun’s energy.
It is considered a cost-effective method to increase the swimming season by providing heated water without incurring the cost of running a heater for the entire season.
An example of a solar pool heater system
You can significantly reduce swimming pool heating costs by installing a solar pool heater.
They’re cost competitive with both gas and heat pump pool heaters, and they have very low annual operating costs.
Actually, solar pool heating is the most cost-effective use of solar energy in many climates.
HOW THEY WORK
Most solar pool heating systems include the following:
- A solar collector — the device through which pool water is circulated to be heated by the sun
- A filter — removes debris before water is pumped through the collector
- A pump — circulates water through the filter and collector and back to the pool
- A flow control valve — automatic or manual device that diverts pool water through the solar collector.
Pool water is pumped through the filter and then through the solar collector(s), where it is heated before it is returned to the pool. The collector(s) can also be used to cool the pool during peak summer months by circulating the water through the collector(s) at night.
Our systems include sensors and an automatic or manual valve to divert water through the collector(s) when the collector temperature is sufficiently greater than the pool temperature. When the collector temperature is similar to the pool temperature, filtered water simply bypasses the collector(s) and is returned to the pool.
