Description
Do you want hot water at home without using a lot of electricity or gas? Then Solar Water Heating is the best solution. It uses sunlight to heat water, which helps you save money and protect the environment.
What Is Solar Water Heating?
Solar Water Heating is a method of using energy from the sun to heat water for use at home or in business. It works using special panels that collect sunlight and heat water inside them. The hot water is then stored in a tank and used later for bathing, washing, and cleaning.
How Does It Work?
Solar Water Heating has two main parts:
-
Solar Collector – This is the panel placed on the roof that collects sunlight.
-
Storage Tank – This stores the hot water so you can use it any time.
When sunlight hits the collector, the water inside gets hot and moves into the tank.
Types of Solar Water Heating Systems
Here are the two main types of Solar Water Heating systems:
1. Thermosyphon Systems
-
Do not need a pump
-
Work best in warm areas
-
Water moves by itself due to heat
-
Good for homes and small families
2. Forced (Pumped) Circulation Systems
-
Use electric pumps to move water
-
Work better in cold areas or multi-story buildings
-
Cost more but give better performance
