Solar water heater

Solar hot water heating systems are a great way to effectively conserve energy and reduce your energy bill.

Contrary to popular belief, this is not a new technology. These systems were used in trade for more than a century now, with the first commercial water heater (the Climax solar-heating-water) pass sale in 1891 in the United States. By the year 1900, more than 1,600 homes in California were equipped with solar heating device.

Because of its effectiveness and low cost, solar hot water has gained in popularity until, in 1941, more than half of the population of Florida became its hot water in this way!

Solar heating has only lost his popularity as a result of a reduced rate of electricity and an aggressive campaign by Florida power and light to increase electricity consumption. This was done by providing electric water heaters at bargain prices. Thus, the production of solar water heater Florida was to stop.

The United States is not the only country with a history of solar heating. There are many other countries where it has been used and has fallen since from use - but not all. In fact, there are currently more than $ 10 million of Japanese households heated their water using solar energy. It is the definitive evidence that it is a viable technology.

Important facts on solar hot water systems

Solar water heater can be used in any environment. His incredible? Discover on the Web site of the U.S. Department of Energy. They say similarly.

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 water heater can reduce your water heating bill by 50 to 80%. But prices of energy in back, the amount of savings will become even higher.

Apart from the reduce your energy bills now, a solar heating system will protect you against the increase in energy prices in the future. You count is more on fossil fuels to warm up.

During the construction of a new home or refinancing, the economic aspect of this becomes even more interesting. For example, you can include the cost of a solar water heater with a new package of the thirty-year mortgage. Usually, this would amount to approximately 13 hours of $-20,00 $ per month. Federal mortgage interest tax deduction would reduce the payment for the by about 3.00 $-5,00 $ per month. If your fuel savings is $15.00 or more per month (which will be likely be) you will have reduced your right monthly heating Bill and then and there.

Using solar energy to heat your water will significantly reduce your carbon footprint. It will reduce the use of fossil fuels which pollute the environment.

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

There are two types of systems, "active solar water heaters" and "passive solar water heaters." They were both working on the same principles.

The only difference is that active systems have a pump or other mechanical movement of the water, while passive systems rely on principles of nature: the hot water rises to the top, and the cold water sinks to the bottom. With a passive system, water storage tanks must therefore always be positioned above the solar water heating collector.

Active solar water heater

There are two main models of active systems. That which is best for you depends on the type of climate in which you live.

There is what is called a "system of indirect traffic" which uses a fluid heat transfer non-freezing to transfer heat from the collector to a heat exchanger (a device used to transfer heat to the heat transfer fluid in your storage tank). It is good for cold climates.

There are also direct circulation system, where the water is simply passed through manifold heat solar and then forwarded to the reservoir of water for use. This system works very well in warmer climates.

Passive solar water heater

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

But, in General, they are not as effective as active systems. If you live in a hot climate, a system of water heating passive perhaps you need. Passive systems are also known to be very reliable.

Essentially, solar water heating systems consist of a water storage tank and its solar collectors. The solar collectors are used for collecting solar energy (which heats the water), and reservoirs to store the heated water. That is all there is to it.

A great way to reduce pollution in the environment is the use of solar energy. 75% of the average home energy consumption is for heating and hot water. Average most economical and efficient use of solar energy is through the use of solar heating and solar water heater.

Solar heating, solar thermal and solar hot water systems

Solar heating systems (solar thermal)

Using solar energy to heat your water is one of the more practical and cost-effective ways to harness energy from the Sun. Solar thermal systems absorb the heat of the Sun and use it for your needs of hot water of the residence of the heat. In General, the solar thermal system be easily heat water 140ºF or higher corresponding to the range of his counterpart traditional hot water tank. Effective systems can collect up to 70% of the energy of the sun which reached their and transfer to you.

Work of hot water heating systems solar how to

In General, there are two types of active water heaters: direct and indirect.

Direct solar water heating

As implied, direct systems capture the sun heat in collectors to directly heat the household water supply. The system consists of collector pipes filled with water and which is related to an isolated storage tank typically located inside a House. As the sun warms the water inside the pipes, the water flows into the storage tank. Although the direct systems are more efficient than indirect, they require more maintenance to keep pipes clear of mineral deposits. Direct solar thermal systems also work best in climates warmer where the system is less prone to freezing.

Indirect solar water heater

Indirect systems does step heat water directly rather than they use fluids with a low freezing point to absorb the radiation from the Sun. Systems closed, also called loop, indirect solar water heating system absorbs the rays of sunlight to heat pipes evacuated of air which in turn heats up to laminated thin copper pipe located at the rear of each stack. The table of the collection consists of several pipe heating which is mounted and tilted to maximize solar collection.

Often glycol (antifreeze ingredient) through adjacent pipes in the table and heats through contact with laminated copper. The temperature in the rise of pipes, heat activates a pump that circulates the glycol fluid in a heat exchange coil in the water tank. This coil, in turn, transfers heat from the water tank and voila, the hot water is produced.

Solar swimming pool and jacuzzi, heating systems

Heating systems solar pool operate on a principle similar to a solar hot water system direct. However, because water can heat too in a solar thermal system, glazing of perception is often removed. The assistance of non-glass pipes or a heating system that resembles a flat matte black prevents the water in the pool become overheated as well as reduced costs for the whole of the system.

While solar swimming pool and jacuzzi, heating often are exempted of the discounts and premiums federal and States, they often pay their own within 1 to 5 years (depending on mainly where you live).

Radiant for your home heating systems

You can also use a water heater solar (or thermal) a system for heating your home. Rather than transfer the water heated to an apparatus for heating domestic hot water, solar hot water system can connect to a radiant floor or a wall panel radiator.

You can make the system of collection and distribution as simple or complex as you like depending on your location, climate and wanted to use. Radiant heating systems more use of the collection table to heat water and store in a tank of high thermal collection so that you have enough heat to last at least through the night. A general rule is to have a collection tank that can store 1½ to 2 litres of water for every square foot of solar collector. That water, in turn, is routed via tubes plastic under floors to create an efficient heating system.

Heating radiant floor have many advantages. They are generally more effective than a forced air heating system of 40 percent and can be zoned so that each room has its own thermostat. In addition, radiant floors distribute heat under your feet where it increases naturally providing a comfortable and spread heated vividly.

Tips for installing solar hot water systems

Tips for cooler climates solar hot water heater

In climates cooler during cold periods of the year, an indirect solar heating system can help reduce your energy costs by working as a system rather than a pure and simple of preheater water heater of the water. The preheated water reduces the load on your other energy systems to heat the water.

Another trick to increase the efficiency of the system is to encapsulate your tank of water with an insulation blanket to keep enough hot water and further reduce the need to rely on traditional energy sources to heat your water. (Note that water heaters not all need a mattress insulation.) Many of the most recent models energy come with a thicker layer of insulation inside the tank which eliminates the need for extra insulation).

Where to put a solar thermal collection system

As other types of solar energy systems, solar hot water heating systems work best on the walls of the South face with the exhibition full sun. Because of the type of collector of construction tubes, exterior elements have less effect on its performance from a system photovoltaic collection; a little shade on thermal table will have a less sensitive effect.

Work with a solar Pro

As with any upgrade of solar energy, consultation with a professional solar energy can help you to assess your potential savings and to determine the type of solar system of hot water which is best for you. Solar thermal panels come from tables of the independent collection and integrated building panels. A solar pro can size your system and help you compare different options for the panels in the collection and the water tank that you need. And don't forget, solar domestic water systems are often eligible for federal, State and local tax credits and rebates!
