How It Works
Serving all of Texas—residential and commercial swimming pool owners. Unlike traditional solar pool heaters that require expensive roof-mounted panels, the STE4 uses the heat already trapped in your attic as a free energy source.
Heat Exchanger Installation
A heat exchanger unit (radiator and fan) is installed in your attic space. This compact system requires no external panels or roof modifications.
Temperature Monitoring
Pool water is automatically diverted to the heat exchanger when attic temperatures are 20°F warmer than the pool temperature.
Heat Transfer Process
The fan draws hot air from across the attic, passing it over the radiator coil. Heat is removed from the attic and transferred to your pool water.
Automatic Safety System
Built-in drain-back system prevents water damage to your attic in the unlikely event of a leak. The system operates automatically with no user intervention.
This effectively turns your entire roof surface into a solar collector without needing any panels.

Optional Flow Reversal Valve
The Flow Reversal Valve moves heated water to the bottom of the pool, creating more efficient heat distribution and doubling the system's capacity for larger pools up to 70,000 gallons.
Environmental Impact
Solar attic pool heating represents a truly sustainable approach to pool temperature management, utilizing energy that would otherwise be wasted.
Zero Fossil Fuel Consumption
No gas, oil, or propane needed. The system runs entirely on solar energy already collected by your roof.
Reduces Home Energy Use
By cooling your attic, the system reduces your overall home energy consumption by lowering AC demand.
Dual Environmental Benefit
Heats your pool while cooling your attic—two benefits from one system, maximizing energy efficiency.
