This is the VOA Special English Technology Report.

Solar water heaters are used around the world and are not very difficult to build.

The system we are going to describe is based on the design developed some years ago in Afganistan. Since then it has been built and used in many countries. It can heat seventy liters of water to sixty degrees celeses.

It can do this between sunrise and noon on the clear day with an average air temperature of thirty-two degrees celeses.

There are two parts of the solar water heating. One part is made of sheet of material painted black. Black surfaces become hotter in the sun then surfaces painted any other color. This black material plate is called a collector.The collector is placed in contact with the water.

There are several times of material sheet that can be used for the collector. Collargated material will work very well. Collargated sheet are often used as loops on the housing.

Once the water is heated, it is kept hot with insolation material. This allows the water to stay warm for a long time.

The second part of the solar water heater holds the water for system. This storage tank can be a container that holds about one handred liters. Two raper pipes are retain to water storiage tank. One pipe lets water flow into the system, the other lets water flow out.

When the water heater is working correctly, water will flow from the storiage tank to the collector and back again. You can use the hot water at the top of the tank for washing and cleaning. You can change the flow of water so that the temperature is hot or warm as design. This solar water heater is easy to build and operate. It will less about two years before the bruber pipes need to be replaced.

The resources something else you will need to make the solar water heater work -- the sun. As you might imagine, the heater will heat the water only on sunny days.

You can get more information about solar water heaters and other project from enterprise work's wite. This group works internationally to fight proverty. The website is enterprise work's.al. Choose the link for news and resources then click on publications.

And that's the VOA Special English Technology Report. Tell us if you ever built the solar water heater or have ideas for improvements.

When the water heater is working correctly, water will flow from the storage tank to the collector and back again. You can use the hot water at the top of the tank for washing and cleaning. You can change the flow of water so that the temperature is hot or warm as desired.

Solar water heaters are used around the world and are not very difficult to build.The system we are going to describe is based on the design developed some years ago in Afganistan.Since then,it has been built and used in many countries.It can heat 70 liters of water to 60 degrees Celsius.It can do this between sunrise and noon on the clear day with an average air tempurature of 32 degrees Celsius.
There are two parts of the solar water heater.One part is made of a sheet of metal painted black.Black surfaces become hotter in the sun than surfaces painted any other colour.This black metal plate is called a collector.The collector is placed in contact with the water.There are several kinds of metalsheets that can be used for the collector.Corrugated metal will work very well.Corrugated sheets are often used as roofs on the housing.Once the water is heated,it is kept hot with insolation material.This allows the water to stay warm for a long time.The second part of the solar water heater holds the water for the system.This storage tank can be a container that holds about 100 liters.Two wrapper pipes are attached to the water storage tank.One pipe lets water flow into the system,the other lets water flow out.When the water heater is working correctly,water will flow from the storage tank to the collector and back again.You can use the hot water at the top of the tank for washing and cleaning.You can change the flow of water so that the tempurature is hot or warm as desired.This solar water heater is easy to build and operate.It will last about two years before the wrapper pipes need to be replaced.
There was also something else you will need to make the solar water heater work---the sun.As you might imgine,the heater will heat water only on sunny days.You can get more information about solar water heaters and other projects from enterprise works vita.This group works internationally to fight property.The website is enterprise works.org.Choose the link for news and resources,then click on publications.
