pools need an entire solar heating system, including a solar collector, filter, pump, and flow control valve. And while that may sound like too much pool technician jargon, it isn't all that ...

“Tesla valves can enhance heat transfer by creating vortices and ... Their findings can be found in the paper “Numerical study on solar photovoltaic/thermal system with Tesla valve ...

Essentially, it allows the water heater to get much hotter during times when solar energy is available, and lets it drop to lower values before running the heater on utility electricity during ...
