🔧 What Is an Automatic Hot Water Diverter?

Turn Free Energy Into Free Hot WaterWhen your solar panels produce more electricity than you’re using, that energy normally gets sent back to the grid. A hot water diverter changes that — it redirects that extra power to heat your water tank first, saving you money every single day.
