🔹 What is an EPDM Pool Solar Collector?
An EPDM (Ethylene Propylene Diene Monomer) solar collector is a type of flexible solar heating mat or panel made from durable synthetic rubber. It is designed to absorb solar energy and transfer heat into swimming pool water circulating through it.
🔹 Working Principles
1. Water Circulation
✅Pool water is pumped from the swimming pool (usually using the existing pool circulation pump).
✅The water flows through a series of small channels/tubes embedded in the EPDM collector.
2. Solar Absorption
✅The black EPDM rubber surface efficiently absorbs solar radiation.
✅The absorbed sunlight is converted into heat, raising the temperature of the EPDM surface.
3. Heat Transfer to Water
✅As the pool water circulates inside the EPDM collector’s channels, it absorbs the heat from the warmed surface.
✅The longer the water stays in contact, the more heat it gains.
4. Return to Pool
✅The heated water is then returned to the swimming pool, gradually increasing the pool’s overall temperature.
✅This process repeats continuously until the desired water temperature is reached.
5. Temperature Control (Optional)
A controller and valve system can regulate when water flows through the collectors, usually diverting flow only when sunlight is available and the collector is hotter than the pool water.
🔹 Key Features of EPDM Solar Collectors
✅Durable & UV-resistant: Withstands prolonged exposure to sunlight.
✅Flexible & lightweight: Easy installation on roofs, pergolas, or ground racks.
✅High thermal stability: Operates effectively from \~20°C to 90°C.
✅Eco-friendly: Uses renewable solar energy to reduce heating costs.
✅ In short: The EPDM solar collector works by circulating pool water through black EPDM rubber mats/panels that absorb sunlight and transfer heat into the water before sending it back into the pool.
