A solar water heater is a device that uses solar energy to heat water for domestic, industrial, or commercial use. It is an eco-friendly and cost-effective alternative to conventional water heating methods that rely on electricity or fossil fuels.
Types of Solar Water Heaters:
Direct System
Indirect System
Passive System
Active System
How It Works
Solar Collectors
Flat-plate collectors: A flat, insulated box with a transparent cover that absorbs sunlight and heats water or a heat-transfer fluid.
Storage Tank
Stores the heated water.
May have additional insulation to retain heat for extended periods.
Circulation System
Active Systems: Use pumps to circulate water or a heat-transfer fluid between the collectors and the storage tank.
Benefits
Cost Savings: Reduces energy bills by using free solar energy.
Eco-Friendly: Lowers carbon footprint by reducing reliance on fossil fuels.
Energy Independence: Less dependence on grid electricity or gas.
Longevity: Durable systems with a lifespan of 15–20 years.
