Solar Water Heater
Description
A solar water heater (SWH) is a system that uses solar energy to heat water for residential, commercial, and industrial applications. It is an eco-friendly and cost-effective alternative to traditional water heating methods that rely on electricity or gas.
-
Active Solar Water Heaters – Use pumps to circulate water or heat transfer fluid.
-
Direct System: Heats water directly in the collector and circulates it.
-
Indirect System: Uses a heat exchanger with antifreeze fluid for colder climates.
-
-
Passive Solar Water Heaters – Rely on natural convection without pumps.
-
Thermosiphon System: Water flows as it heats, making it highly efficient.
-
Integral Collector-Storage (ICS): Stores and heats water in an integrated system.
-
Benefits of Solar Water Heater
-
Energy Efficient: Reduces electricity or gas consumption.
-
Environmentally Friendly: Lowers carbon emissions.
-
Cost Savings: Cuts utility bills with free solar energy.
-
Long Lifespan: Can last 15–25 years with minimal maintenance.
