Solar Hot Water Family Articles | September 20 Wholesale Astros Hats , 2008
A great way to save on energy costs, and reduce harmful fossil-fuel emissions, is to use a solar hot water heater in your home. Getting this installed is simpler than one might imagine. This article describes how solar hot water heaters work, just about anywhere on the earth, and how effective they are.


Solar hot water heating systems are a great tool for conserving energy and significantly reducing your energy bill.


Contrary to popular belief Wholesale Astros Hoodies , solar hot water heating is not at all a new technology. Solar water heating systems have been used commercially for over a century now, with the first commercial water heater (the Climax Solar-Water Heater) going on sale in 1891 in the United States. By the year 1900, over 1600 houses in California were equipped with this solar water heater.


Due to its low cost and its effectiveness, solar hot water heating gained popularity until, by 1941 Wholesale Astros Shirts , more than half the population of Florida was getting its hot water through solar water heaters!


Solar water heating only lost its popularity as a result of lowered electricity rates, and an aggressive campaign by Florida Power and Light to increase electrical consumption. This was done by offering electric water heaters at bargain prices. Thus Florida's solar water heating was brought to halt.


The United States is not the only country with a solar water heating history. There are many other countries where solar water heating was used in the past and has since fallen out of use - but not all of them. In fact, currently more than ten million Japanese households heat their water using solar water heating systems. This is definite proof that it is a workable technology.


Important Facts about Solar Hot Water Heating Systems


* Solar water heating can be used in any climate. Sound unbelievable? Check it out on the U.S. Department of Energy website. They say so as well.


* The fuel used to run a solar water heater is sunshine. And, at the time of this writing, sunshine is free - no tax has been added yet.


* A solar hot water heater can reduce your water heating bill by fifty to eighty percent. But with energy prices going up Wholesale Astros Jerseys , the amount of savings (as compared to normal prices) will soon be even higher.


* Aside from reducing your energy bill right now, a solar water heating system will protect you from future energy price increases. Your heating will no longer rely on fossil fuels for electricity.


* When building a new home, or when refinancing, the economic aspect of this becomes even more interesting.


You can, for instance Cheap Astros Hats , include the cost of a solar water heater with a new thirty-year mortgage package. This would usually add up to about $13.00 -$20.00 a month. Federal income tax deductions for mortgage interest would reduce the payment for the solar water heater by about $3.00 -$5.00 per month.

* Solar hot water heating will significantly reduce your carbon footprint. It will reduce the use of fossil fuels which pollute the environment.


* Solar heaters can be installed in combination with backup systems. In fact, you could install a solar water heater next to your existing system and make it possible switch to conventional water heating whenever necessary. This way you are guaranteed to always have hot water.


-Types of Solar Hot Water Heating Systems


There are two types of solar water heating systems, active solar water heating systems and passive solar water heating systems. They both work on the same principles.


The only difference is that active systems have a pump or other mechanical means of moving the water through the solar heating systems, and passive systems rely on nature's principles: warm water rises to the top, and cold water sinks to the bottom. Therefore Cheap Astros Hoodies , with a passive solar water heating system, the water storage tank must always be positioned above the solar water heater collector.


- Active Solar Hot Water Heating


There are two main designs of active water heating systems. Which one is best for you depends on the climate you live in.


There is what's called an "indirect circulation system" which uses a non-freezing heat-transfer fluid to transfer heat from the collector to a heat exchanger (a device used to transfer heat from the heat transfer fluid to the water in your storage tank). This is good for colder climates.


There is also the direct circulation system, in which case water is simply passed through solar heat collector and is then routed to the water storage tank for use. This system works fine in milder climates.


- Passive Solar Hot Water Heating


Passive solar water heating systems are usually cheaper than "active solar water heating systems," as they do not need controls or pumps to circulate the water.


But generally, they are not as effective as the active systems. If you live in a warm climate Cheap Astros Shirts , a passive water heating system may be all you need. Passive water heating systems are also known for being very reliable.
