Things you will need to make Solar Water Heater
- Plastic Soda Bottle
- Black Paint or Black Paint Spray
- Black Fabric
- Elastic Band
5 Steps For How to Make a Simple Solar Water Heater
1-Take a large empty plastic soda bottle. A bottle with 2 to 3 liter capacity would be enough to make a Solar Water Heater.
2-Now, take a black paint or black spray and coat the soda bottle completely. Wait for a few minutes until the paint or spray dries well. It
helps in preventing the heat from escaping. However, if you do not have paint then you can use a black fabric as well. Make sure to secure
the black fabric with a thread or an elastic band so that it collects heat properly.
3-Gently pour water into the bottle until filled completely.
4-Now, place the soda bottle in the sunlight where it can receive the rays of sun. Put it in a closed car because it is a great idea, working
effectively. Other than that, you can place it behind glass on a window. You can use a shinny equipment like a mirror or foil to grab extra
power and to attract the rays of the sunlight. Leave the bottle in sunlight for a few hours until the water warms properly. Wow! You have
enough of warm water without using even a single unit of electricity.
5-You might be thinking of the winter when sunny days rarely happen. Do not worry at all and place the same painted bottle near a radiator
to get warm water.
