How to Build a Homemade Solar Water Heater


In a world where fossil fuels are running low and where electricity becomes expensive with each passing day, people have to adapt and start living independent of these resources.
Considering all alternative energy sources available today, people should start implementing them in their lives, in their homes.

This is the reason why I chose to show you in this post the simplest way to build a solar water heater for your home.

Assembling this system is not very difficult but it is important to take into account several things:

Before you start installing this solar heating panel, you have to decide where it will work best. It should be installed where it can find maximum sunlight. It is also better if you’ll keep it close to the back up heater.

For maximum efficiency and zero risks you have to use water tight panels sealed with plexi-glass. To make it water proof it should be endorsed with black pond liner.

Today, panels are made of thin cylinders because of their greater efficiency. Plywood tank is a substitute for the thin cylinder, which is a shallow box with the plywood bottom and four walls used for the water tank.

At the bottom of the panel you have to connect the pipes using connectors. The role of these pipes is to drive water from the house to your solar heater. With another set of pipes connected at the top of this heater you’ll send the warm water back to the house.

The color you’ll use to paint your solar heater will be black (including the inner side of the panel). Black color absorbs light rays better than any other color and it stores heat energy efficiently. You have to make sure that the paint dries completely.

Now when you’re almost done, you have to cover your panels with a part of plexi-glass acrylic plastic.

For the purpose of glazing glass is the most appropriate material (for homemade water heaters). To avoid leaks, glazing should be done carefully and also make sure to glue the panes perfectly to avoid condensation.

This homemade solar water heater should not be very difficult to build. Give these plans a try and start build it. Good luck!
