According to Solar Direct, there are more than 300,000 solar water heating units installed in the U.S., and the number is growing as people realize the many advantages of solar heating. </p>  <p><strong>Systems</strong></p>  <p>There are two types of solar water heating systems--passive and active. Passive, as the name implies, involves no moving parts. The simplest passive system consists of a dark-colored water tank exposed to sunlight. Thermosyphon passive heaters work on the principle of convection, in which hot water rises and cold water sinks within the tank in a continual process as long as there is sunlight available. Active systems employ pumps to move water from the collector to the water tank. </p>  <p><strong>Available Energy</strong></p>  <p>One of the biggest advantages of solar energy is that it is readily available to everyone, cutting out the necessity of the middle-man energy provider. According to one Arizona utility company, just a portion of the roof of a typical house receives more energy than is needed to heat water for its occupants for more than a year. There are systems designed to work in any climate. </p>  <p><strong>Cost Effective</strong></p>  <p>Initial costs to install a solar water heating system range from $2,500 to $5,000 for an active system, which will produce between 80 to 100 gallons of hot water per day, to as little as $1,000 to $2,000 for a passive system with lower capacity. Since solar water heating systems save more than 50 percent on hot water energy bills, most homeowners recoup these expenses within 10 years. Homeowners also receive federal and state tax credits for installing solar power systems. </p>  <p><strong>Other Advantages</strong></p>  <p>Using solar energy has a positive impact on the environment by reducing the use of nonrenewable energy sources to heat water, such as gas, coal, oil or nuclear power. Solar energy is safe, efficient, reliable and non-polluting. The consumer has direct control over the system, and unlike conventional water heaters, hot water is available even during a power outage. </p><p>Copyright © 2008</p><p><a href="http://www.tranc.org/post/35.html" target="_blank">继续阅读《What is the Advantages of Solar Water Heating Systems》的全文内容...</a></p><p>分类: <a href="http://www.tranc.org/catalog.asp?cate=8">FAQs</a> | Tags: <a href="http://www.tranc.org/catalog.asp?tags=solar+water+heater">solar water heater</a>&nbsp;&nbsp;<a href="http://www.tranc.org/catalog.asp?tags=solar+energy">solar energy</a>&nbsp;&nbsp; | <a href="http://www.tranc.org/post/35.html#comment" target="_blank">添加评论</a>(0)</p><h3>相关文章:</h3><ul><li><a href="http://www.tranc.org/post/39.html">SR868C8Q solar water heater controller for split pressure solar water heater</a> (2010-9-3 14:0:42)  </li><li><a href="http://www.tranc.org/post/38.html">SR868C8 solar water heater controller for split pressure solar water heater</a> (2010-9-2 20:23:46)  </li><li><a href="http://www.tranc.org/post/37.html">SR500 solar water heater controller for compact non-pressure solar water heater controller</a> (2010-9-2 19:13:39)  </li><li><a href="http://www.tranc.org/post/34.html">How to choose a best solar water heater for my own house?</a> (2010-9-1 8:53:20)  </li><li><a href="http://www.tranc.org/post/does-solar-cost-a-lot.html">Do solar systems cost a lot?</a> (2010-8-17 16:50:57)  </li></ul>]]></description><category>FAQs</category><comments>http://www.tranc.org/post/35.html#comment</comments><wfw:comment>http://www.tranc.org/</wfw:comment><wfw:commentRss>http://www.tranc.org/feed.asp?cmt=35</wfw:commentRss><trackback:ping>http://www.tranc.org/cmd.asp?act=tb&amp;id=35&amp;key=45ec727a</trackback:ping></item><item><title>How to choose a best solar water heater for my own house?</title><author>ultisolar@gmail.com (WoolfZhang)</author><link>http://www.tranc.org/post/34.html</link><pubDate>Wed, 01 Sep 2010 08:53:20 +0800</pubDate><guid>http://www.tranc.org/post/34.html</guid><description><![CDATA[<p>Solar water heaters can be money savers and are environmentally friendly, but the initial purchase can be expensive. When purchasing a solar water heater, it is important to look at the different types of solar water heaters available to determine which type would work best in a specific home. A solar water heater can save a household anywhere from 50 - 80 percent of the current fuel cost of water heating, so choosing the very best option will help maximize that savings. </p>  <p>The first thing to look at is geographic location. Though solar systems are available for all climates, different regions will benefit from different types of heaters. A solar water heater is either active or passive. An active solar water heater uses circulation pumps and controls and a passive heater doesn't. That means an active solar water heater requires electricity and a passive system does not. Passive solar water heaters are best used only in warm climates. </p>  <p>Active solar water heaters are either indirect or direct circulation systems. Direct circulation systems work in climates that rarely freeze, but colder climates will require an indirect circulation system. Both types use collectors to take the energy from the sun to heat the water. An indirect circulation systems uses a non-freezing heat transfer fluid that circulates through the collectors. This fluid collects heat then transfers it to the water used in the home. Direct systems circulate the water to be used through collectors. </p>  <p>Two types of passive solar hot water heating systems are available. The first is an integral collector-storage system in which the storage tank acts as the collector. These are generally painted black. The sun heats the water directly, then water pressure from a well or city water pushes the heated water to the faucets or another holding tank within the house. The second is a thermosyphon system in which the storage tank is mounted above the collector and gravity pushes the heated water through the tank, but these must be mounted on a roof and are therefore not appropriate for all homes. </p>  <p>So, when selecting a solar water heater, it should first be determined which type is appropriate for the climate in which it will be installed. Next, determine the amount of solar energy available. This will help determine the solar efficiency. The amount of hot water needed must also be noted. This determines the size and type of collector and storage tank. Finally, check prices and weigh all the other factors to determine the biggest savings and most efficient solar water heater for the location, size, and use of the home. </p>  <p>Still have more questions, please don't hesitate to contact me by ultisoalr@gmail.com    <br />Or you could check www.cnskylight.com for more useful information on solar water heater</p><p>Copyright © 2008</p><p><a href="http://www.tranc.org/post/34.html" target="_blank">继续阅读《How to choose a best solar water heater for my own house?》的全文内容...</a></p><p>分类: <a href="http://www.tranc.org/catalog.asp?cate=8">FAQs</a> | Tags: <a href="http://www.tranc.org/catalog.asp?tags=solar+water+heater">solar water heater</a>&nbsp;&nbsp; | <a href="http://www.tranc.org/post/34.html#comment" target="_blank">添加评论</a>(0)</p><h3>相关文章:</h3><ul><li><a href="http://www.tranc.org/post/39.html">SR868C8Q solar water heater controller for split pressure solar water heater</a> (2010-9-3 14:0:42)  </li><li><a href="http://www.tranc.org/post/38.html">SR868C8 solar water heater controller for split pressure solar water heater</a> (2010-9-2 20:23:46)  </li><li><a href="http://www.tranc.org/post/37.html">SR500 solar water heater controller for compact non-pressure solar water heater controller</a> (2010-9-2 19:13:39)  </li><li><a href="http://www.tranc.org/post/35.html">What is the Advantages of Solar Water Heating Systems</a> (2010-9-1 9:18:3)  </li><li><a href="http://www.tranc.org/post/does-solar-cost-a-lot.html">Do solar systems cost a lot?</a> (2010-8-17 16:50:57)  </li></ul>]]></description><category>FAQs</category><comments>http://www.tranc.org/post/34.html#comment</comments><wfw:comment>http://www.tranc.org/</wfw:comment><wfw:commentRss>http://www.tranc.org/feed.asp?cmt=34</wfw:commentRss><trackback:ping>http://www.tranc.org/cmd.asp?act=tb&amp;id=34&amp;key=b5d882ae</trackback:ping></item><item><title>SPII solar water heater controller for split system and pool system control</title><author>ultisolar@gmail.com (WoolfZhang)</author><link>http://www.tranc.org/post/33.html</link><pubDate>Tue, 31 Aug 2010 16:42:40 +0800</pubDate><guid>http://www.tranc.org/post/33.html</guid><description><![CDATA[<h6><strong>Main technical data</strong>     <br />01.

</h5>  <p>A special liquid within the heat pipe is heated by the sun to a vapor,</p>  <p>The vapor rises to the top of the heat pipe (condenser)</p>  <p>Cold water or heat transfer fluid runs through the header pipe,</p>  <p>The water or heat transfer fluid is heated by contact with the condenser,</p>  <p>The vapor returns to liquid and falls to the bottom of the heat pipe,</p>  <p>Liquid is reheated &amp;
