Solar water heaters are used around the world and not very difficult to built.The system we are going to describe is base on the design some years ago.Since then it has been built in many countries.It can heat 70 liters of water to 60 degree (Celsius).It can do this between sunrise on the noon, on the clear day on average temperatur--temperature of 32 degrees Celsius.
There are two parts of solar water heater. One part is made by a sheet of metal paint black.Black surface became hotter in the sun than paint other color.This black metal plate is called collector.The collector is placed in contact with the water.There are several kind of metal heater can be used for the collector.Corrugated metal works very well. Corugate sheet metal are offen used as group on housing.Once the water is heated, it keep hot with ins--insulation  material.This allow water to stay warm for a long time.
The second part of the heater hold water for the system.This storage tank could be a container hold about 100 liters of water.Two (rubber) pipes are attached the storage tank. One pipe let water flow into the system.The other let water flow out.When water heater is working correctly,water will flow from storage to collector and back again. you can use the hot water on the top of the tank for washing and cleaning.You can change the flow of water so that the temperature could be hot or warm as desired.This water heater is easy to built and upgraded. It will last about two years before rubber pipes need to be replaced.There is also something else you will need to make solar water heater work. The sun as you might image that the heater will only heat water in sunny day.You can get more information about solar water heaters and other projects from enterprise works. this group internationally to fight poverty.The website is enterpriseworks.org.

This is the VOA Specal English Technalogy Report. Sola water hitters are used around the world and are not very difficut to build. The system will going to descript its base on it design develop some years ago in Apcanastan. Since then, it has been build and used in many countries. It can heat 70 litters of water to 60 digrees cesies. It can do this between sunrise and noon on a clear day in the navelige year tempuriture of 32 digrees cesies. They are two parts of the sodawater heater. One part is made the mechine of metal panting black. Black * hard in the sun then * pant it in the other color. Black metal plate is called a cellecty. The cellecty is played in contect with the water. They are sevaral pans of metal sheets that can be used for the cellecter. Colagate metal will work very well. Colagate chips are often use as woops on housing. Once the water it is heating, it is cap hard with inserlation meterial. This arowds the water stay warm for a long time. The second part of sodowater heater hold the water for system. This storistan can be a continer that holds about 100 litters. Two raber pias are retech to water storiestack. One pip lets the water flow into the system. One pip lets water flow out. When the water heater is working cerectly, the water will flow from the storistan to the cellecter and back again. You can ues the hot water at the top of the tan for washing and cleaning. You can change the flow water so that tempureture is hot warm as design. This sodawater heater is easy to build and arperate. It last about two years before the rape pips need to be place. They are also something else you are lead to made the sodawater *. As you mind the megen, the heater only on sunny days.

This is the VOA Special English technology report. Soller water it is are  used around the world, and not very difficult to bill.The system we are gain to do scrave  *design develop some year ago in the Afgan.
Since then it has been bill and used in many country,it can hit seventy letter in the water to six degree saorils. It can do this between sunlize and noon on the clear day,  * temperature of 32 degrees sellres.
Thare are two parts of the soller water heat ,one part is made of sheet metal pen black, black services become hots in the sun then service painted in the other color. This black metal plat is called a collector ,the collector is play staying concutesk with the water.
There are several tin the metal sheets,they can be used the collector, collegates metal will work very well, collecgate cheets often used as roops on the healthy. Once the water is heated, it is cap top with the solation metrial, this a longth water still warm for a long time. The second part the solove of the water heated, hold the water for the system,this storage tan can be a container that hold about 100 leaders, two ruper pies s* the touch the water storage tans. One type lets water flow into the system, the other let water pull out. When the water heat in it's working correctly, water will pull from the storage tans to the collector and back again. You can use the hot water as the top of tans for washing and clearing. You can change the flow of water so that the temperatury into hard  more warm as the degin.
So the water heated is easy to build and ubray. It is the last two years before the rubble pipes need to be replace. There was also something else you were leave to make the siloor water heat work the sum as your mind megin they heat the water only on the sunny days.
You can get more information about siler, water ,heaters, and  * projects from enterprice works witor.This group works internationaly the five  populty, The website is enterprice works dupall.C* learn for use and resovles then collect on publications.
And that's the  VOA Sepceial English technology report. Tell us if you ever billses solor water, heater or have a idea for improvements, Puts your comments at voaspecialenglish.com,
