Hot water is required by everyone, and a water heater is an essential need of a family. A conventional water heater uses a good percentage of electricity to meet the water heating needs, which proves to be really costly in the long run. An approximate amount of 6000 kilowatt hours is consumed only by an electric heater in a year when used by an average family of four. This amount of electricity when multiplied by all the homes using the water heater, will amount to huge amounts of electricity being produced and wasted and production of more carbon dioxide, than automobiles do. Carbon dioxide causes the greenhouse effect and increases the heat inside the atmosphere. All this can be controlled by using a solar water heater as it doesn’t use electricity or any other fuel, only the sun’s energy, which is absolutely free. Solar energy is very friendly to the environment and does not create any type of waste and does not pollute the atmosphere. That is the reason why it is ecologically acceptable, as well. There are mainly two major types of solar water heater. One is an active solar water heater and the second are passive solar water heaters. The difference lies in the types of heating systems. In case of active solar water heater, water is heated by using direct and indirect circulation systems whereas in passive water heating systems water is heated by integral collector storage and thermo siphon system. A solar water heater has a high initial cost, the price, which can easily be provided by any nationalized bank, at very low interest rates (3% to 5%), which in turn brings huge savings for your family. A solar water heater typically has a life span of more than 25 years and if properly installed doesn’t require servicing and maintenance. Different factors determine the amount of hot water provided by solar water heater, the principal one’s are: The amount of sunshine the site can access. The type and the size of the solar heater to be installed are considered according to family requirements. The weather of the area. .Basic design of the building, where it has to be installed. Electric water heaters consume a large (15 to 20%) proportion of electricity which as the time runs adds up to large amounts. Home owners who have installed a solar water heater unit keep on praising it and are overwhelmed that they did. They save money on a monthly basis and have an abundant amount of hot water for their...

It even assists by giving time to time guidance when it is needed. A person should choose the proper type of solar water heating system and there are mainly two types of it. • Direct systems-these systems heat water directly. These systems are used where there is no frost and chemical content present in water is low. • Indirect systems-these systems heat water with the help of heat exchange system. These systems are used where there is frost and chemical content present in water is high. Water storage There are mainly two types of water storage tanks present in the market. • Pumped storage- This type of tank is situated away from the solar panel and the tank is not visible. • Thermo siphon storage- This type of tank is located above the solar panel and water is mobilized by natural process. It is used in the places where the roof of the house can bear the weight of the...

The usage of solar energy heaters has garnered huge popularity recently. These solar energy water heaters that use the sun’s energy to warm up water initiate a process in conserving energy. It is quite efficient and warms up the water at a great pace. Many homes nowadays, instead of electric water heaters prefer to use it. Reasons for preferring a solar water heater: Solar water heater is preferred by a large number of people because it reduces costs and helps in saving energy. It employs solar energy to get hot water quite instantly. The energy derived through the sun, is then caught by the panels embedded in the heaters, which is further shifted to the batteries that help to warm up the water. Thus, by this process, energy is renewed to be used again and again in an effective manner. There are a lot of benefits of bringing it in use as one can install them in their homes very easily. It is not really difficult to build the water heaters too. Rather, installing the heaters is quite economical when contrasted against other water heaters. These solar heaters work by changing the solar energy for heating water; it is also eco-friendly. These heaters are really faster, which is an advantage and is also completely free of the cost compared to the water heaters, which run electrically. Electric water heater consumes too much of power and thus, increase in its usage adds up to the electricity bills. Also, it is not possible to heat the water during power failures.

To install a solar heater to heat up water is really fun. One can install it in their home or vacation house. It is an actual energy saver and one need not necessitate relying on electricity. It is not at all difficult to build and will automatically reduce the electricity bills. With the growing awareness, one can easily find manufacturers dealing with it. The type and specification of the water heater will depend on the area one lives geographically. Presently, there are more than 300,000 water heaters that are installed around the whole of the United States and many more are being installed every year. One can buy already built systems that are ready to go directly into their homes, or they can even build their own if they feel. One just requires a set of plan and proper execution by following the instructions. There are two types of solar heating systems for heating water: these are the working (active) and dormant (passive) systems. The active system consists of circulating pumps, which controls the system, whereas the passive system has not got any such mechanism. The active solar water heating system comprises of two types: with direct and indirect systems for circulation. The previous one is helpful in climates and weather where it freezes rarely while the other is effective in places inclined to freezing temperatures, like cold countries.

The Solar water heater systems are water heaters that work with the energy of the sun. They are constructed to be working with pumps or fans for gathering the heat, with no automated parts included in the system. Solar water heaters are around since the late 1800’s. From the early 1900, there has been a change and new ones are being used. For the past forty years, these renewable sources of energy have contributed a lot. They have solved many problems such as oxidation, rusting and the problem of shortage of hot water. Contrast can be drawn between the two kinds of working solar heaters: The active solar heaters are the heaters in which the heat collector protects it against cold conditions. These systems are called: Re-circulate, duct-down, duct-back, and heat exchange. The re-circulate system: The mechanism employs a pump, running electrically to canalize water through the container to avoid it from freezing. Some heat is employed to heat the moving water. The duct-down system This mechanism simply procures the water out of the container, which collects it, when the thermostat indicates the boiling point of water. But, if the electricity is low, then all the water is emptied down by the collector. The duct-back system This mechanism uses heat exchanging systems for the storage of drained water from the collecting device when it reaches the freezing point. Heat exchangers activate with a storage tank and help the water to advance to the actual water heater. The duct-back system has an electric running pump that works almost all the time. But, if it is not activated, the heat exchanger contains the hot water from the container and uses this water as the material for heating fluid to warm the water. The heat exchanger looses up to 10% of its heating efficiency. The high temperature exchanging system In this system, water does not come out from the collector when it comes near freezing. The heat exchanger, which is present in the system, takes the help of an oily fluid whose job is to prevent freezing and helps to keep the water warm. In many systems compressed air also does the same job what this oily fluid does. The solar water heater systems contain pumps and fans that help in heating up water and moving the water to different parts. So such systems need some sort of maintenance over a short period of...
