@sevenstarssolarenergyke: Where is the magnesium rod placed in a solar water heater? In models fitted with one, it sits inside the water storage tank, in contact with the water. It helps protect the tank from corrosion by gradually corroding itself, so periodic inspection and replacement are part of maintenance. 📞 0728 681 222 / 0722 243 028 🌐 Seven Stars Solar 📍 Kellico Complex, Ground Floor, Mombasa Road #SolarWaterHeaters #MagnesiumRod #SolarMaintenance #WaterHeating #SolarTips
