It’s entirely possible to heat your water with solar energy, while saving money on your energy bill. You can also help clean up the environment by using solar power instead of using polluting fossil fuels. And if you want, you can even build your own solar water heater.
Building a solar hot water heater is actually not that hard. Although there are many designs and systems for solar water heaters, a few of them are relatively simple. It’s the ideal do-it-yourself project, if you are so inclined.
Here is one of the simplest versions of do-it-yourself (DIY) projects for solar water heating. But don’t let the term “simple” fool you into thinking that this is not an effective way to reduce your energy bill.
The basic design of a Batch Solar Water Heater consists simply of a water tank within an insulated box with a glass top.

Solar water heaters heat the water from the energy of the sun. There are two types of heaters, the passive and active. The passive has no moving parts and the active requires a pump and controller. The passive heater is the oldest style of solar water heaters.
The pump used in the active system is used to circulate the water and a controller is used to turn the system on or off. Active systems are more efficient than passive but require electricity and can be more difficult and expensive to put together.
The active system will have a holding tank and one or more solar collectors possibly mounted on the roof. There is a controller that senses the water temperature of the water leaving the solar collectors and the water at the holding tank. The controller will know when to turn the pump on or off according to the temperatures it senses.
