Solar water heater: An effective way to heat your water

January 4th, 2010 admin

Many families around us spend a healthy part of their money for heating water for daily uses. Hot shower, bath, cleaning clothes and a lot of other things is done by electricity or gas supplied by large companies. However the energy we are using is not renewable and may go dry in the long run. The average household consumer finds electricity bills going up steadily above inflation figure. Thus everyone is looking for a suitable alternative source of energy. So the best way to extract this alternative source of energy is from solar energy. Solar power is an effective way to heat water and has been successful for close to 100 years now.

Solar water heating is a heating process during which water is heated up with the solar energy. It is possibly the simplest application of solar energy. It is the process of harnessing the thermal rays of the sun and applying it to water. The question that remains to be answered is ?Where to place the water heater?? The possible answer could be that place the solar water heater at a place where you can extract maximum sunlight from the sun. Maximum sunlight should be received by the solar heater. One popular location could be roof where the solar water heater receives maximum sunlight.

You place it in the center of tank and when you use water, it touches the heater. Solar water heating heats your water before that it reaches the taps. The heater keeps on revolving around the water. Water will move in circular path around the heater as a result, it will be heated up. Thus, solar water can be beneficial not only because of its easy usage but also because it is cheap and helps you to save a lot of money in the form of electrical bills. Solar energy is free and it reaches all homes. You just have to buy such heater which may heat up your water within the tank by using solar energy. So, use heater which use solar energy for heating water and save your money for whole life.

Purchasing and installing a solar water heater will cost a about ?5,000 but the maintenance cost is low and it could last anywhere from 20 to 25 years. You should always buy heaters for solar water heating from companies which sell solar panels. These companies sell heaters which can heat up water within your tanks. You just have to order heaters for solar water heating and the company will give you a heater. They can fit heaters in your tanks which may use solar energy and may heat up water of your tanks. They are professional people and have more knowledge than you do. So always take the services of such companies for purchasing and installing solar water heaters. The company can tell you some special instructions which can increase the age of your heating and can help you to make maximum savings. They own the responsibility of repairing or replacing it if anything happens to the heater.

Heat Your Water With a DIY Solar Water Heater

December 20th, 2009 admin

For most people when they think about Solar Power they immediately think about the solar panels that you currently see being used on people roofs to create electricity, but the power of the sun can be harnessed in another way. The suns energy can be used to heat water for your home, and you made be surprised that you can build a DIY Solar Water Heater, and that it really isn’t that hard to do.

This basic idea really isn’t a new one, the ancient Greeks used crude mirrors and lenses that used direct sunlight to heat water. Then in 1920s some communities had a fully functional solar water heating systems that provided water to their homes.

The solar heated water has direct uses in your home for example for showering or for washing the dishes. Once the water has been heated, nothing more has to be done to the water other than simply make it available. That’s typically done by storing the heated water in essentially the same way as with ordinary water heaters, in a large insulated water tank.

How does it work?

The way the water is heated is really the same as what happens is a greenhouse. A solar water heater panel is like a large, thin and double-paned windows, that contain a series of channels, tubes and pipes. The water is pumped through these channels and heated by the suns energy, and this heated water is then stored in an insulated water tank.

In the ordinary hot water system the water heater storage unit, heats the water. With a solar-powered water heating system there’s no need to, since the water that enters the tank is usually between 95F-150F (35C-66C). The storage tank acts like a big thermos bottle. It’s double-lined and/or made of well-insulated material so the heat doesn’t dissipate much out the walls of the tank.

The temperature range of such systems is fully adequate for bathing, cleaning clothes and other ordinary applications. The only difficulties are ensuring enough sunlight to generate enough heat, and minimal loss of heat through the panels and pipes. So you really have to think about where you place your panels.

In the average home the cost of heating water is roughly a third of the total energy bill. By building your own solar heating panels you not only be saving money on the building of the panels but also on your energy bills. The process of actually building the panels is relatively easy, but it is recommended to learn as much as you can before starting to build. On the internet you will find a wealth manuals and information that will take you right through the whole process from start to finish.

You should be able to find the majority of materials you need to build the panels in your local hardware store, and if not you can also have a look on the internet.

Building a solar water heater one of the easier ways you could save money on your utility bill, but you will also be doing your bit to help the environment.

Solar Water Heaters – the Heat Wave of the Future

November 2nd, 2009 admin

Another name for solar water heaters is “domestic hot water systems”. They are a very cost-efficient way of keeping your home warm. One great perk of this particular process is that it can be used regardless of what type of climate you live in, and you get your energy from a free source, the sun.

There are two types of solar heating systems that are most commonly used for residential purposes. Each of these collectors includes a storage tank and a solar collector. The first type is “active” which has circulating pumps and controls and the second type is “passive” which don’t require pumps or controls.

Solar water heaters need a storage tank that is insulated well. They have an outlet and an inlet that is connected to the collector. A two-tank system has a water heater that is powered by the sun and preheats water before it enters the water heater. In a one-tank system the back-up water heater is joined with the solar storage in one tank.

For residential purposes there are three types of solar collectors; Flat-plate collector, integral collector-storage systems, and evacuated-tube solar collectors. The flat-plate collector has glazed flat-plate collectors. It is insulated and contains weatherproof boxes with a dark absorber plate under one or more polymer (plastic) cover. There are also unglazed flat-plate collectors that are often used for heating pools and also have a dark absorber plate, but without a cover.

The second type is integral collector-storage systems. They are also known by their initials ICS, or batch systems. They have at least one black tank or insulated tubes within a glazed box. The cold water starts by rushing into the solar collector where it is preheated. From here the water flows to the backup water heater and creates a reliable source of hot water. An important note is that these should only be installed in mild-freeze climates because the pipes could freeze when outside in the cold weather.

The last type of solar collector is the evacuated-tube solar collector. In this type of solar collector there are dual rows of parallel transparent glass tubes. In each tube there is an outer glass tube and a metal absorber tube which is attached to the fin. The fin has a coating that absorbs the solar energy and at the same time inhibits radiative heat loss. This type of collector is the most commonly used collector in U.S. commercial applications.

There are also two types of active solar water heating systems. The first type is the Direct Circulation system. This system has pumps that circulate household water through the collectors and back into the home. This type of collector is only effective in a climate that doesn’t freeze often.

The second type of commercial solar heating system is the Indirect Circulation system. This system has pumps that circulate a nom-freezing fluid that transfers heat. The heat flows through the collectors and then through a heat exchanger. After the water is heated in this fashion it flows into the home and heats it. These are very good for homes that are in areas that are prone to freezing.

Can Solar Panels To Heat Pool Be Used For Other Household Purposes?

November 1st, 2009 admin

Hi there, my father just bought a house that has solar panels on the roof to heat the water for his pool. The water goes through pipes by the panels and flows back into the pool. I was wondering if there is any way to use that solar energy for other areas of the house. The panels were put in when the house was built in the mid 80’s and the house is in Central Florida/E. Orlando.
Thanks in advance!
