Water
Heater
A solar water heater is a system that uses solar energy to heat water for residential, commercial, or industrial use.Thus, it reduces dependency on the electric or gas and makes it environmental friendly in relation to heated water.
Types of Solar Water Heaters
Types of Solar Water Heaters
- Passive Solar Water Heaters (No pumps, relies on gravity)
- Integral Collector Storage (ICS) Systems: Water is heated in black tanks inside an
- insulated box.
- Thermosiphon Systems: Cold water flows down while hot water rises, creating a natural
- circulation.
- Active Solar Water Heaters (Uses pumps to circulate water)
- Direct Circulation Systems: Pumps water directly through solar collectors and into the
- house.
- Indirect Circulation Systems: Uses a heat exchanger to transfer heat from a non-freezing
- fluid to the water.
Key Components
Key Components
- Solar Collector: Absorbs sunlight to heat water.
- Storage Tank: Stores heated water.
- Pump & Controller (in active systems): Circulates water.
- Backup Heater: Provides hot water when sunlight is insufficient.
