An Introduction to the solar Water Heater

Posted by on Jan 11, 2014 in Posts

Conventional water heaters particularly the gas and the electric one’s are good and require low initial investment to setup, but in the long run they prove to be costly and inefficient; whereas a solar water heater is equally effective in providing ample amounts of hot water up to 140°F at almost no cost. Multiple factors determine the amount of hot water a solar water heater can provide the principal one’s ear: The ability of the site to access sunshine. The type and the size of the solar heater to be installed. The typical climate and its influence on the site. Basic design of the building in question. “Flat plate” solar water panels are the most commonly used ones, it consists of simple and durable parts namely a weatherproof, thermally insulated box made up of aluminum or ceramics and one absorber plate. Its more expensive counterpart is a concentrating type system, which can heat water up to much higher temperatures, but are less effective on cloudier days than their less costly counterpart. Before going for a solar water heater, one should get a free energy audit of their homes to precisely determine the cost savings one can get. There are certain factors that should be considered for an energy audit. The important ones are: Expenditures and complexities to set up piping, ducts and plumbing from the terrace on the ground floor. Whether the roof is suited and accessible so that power panels can be fitted, and if not then an equivalent place on the ground. If wall sections will be required to open up to allow water pipes to pass through. The room’s on the ground floor and the basement has space for a water tank, and if it is possible to move or load the water tank in it. The time required and the ability of the roofing materials to fasten with the collector’s support. (e.g. Materials like slate, tiles, and clay are difficult to work with) Aesthetics and design of the home once the system is in place. Some tips and advices for the best functioning of your solar water heater: Always keep the solar collector panels facing the sun at a right angle. Bypass or avoid shade particularly during 9 am and 3 pm. Set up the solar water heater such that it faces true south and not towards the compass...

Passive Solar Water Heaters

Posted by on Jan 11, 2014 in Posts

Passive Solar Water Heaters – How are they different from Active Solar Water heaters? Looking at the present scenario, Energy uses have risen tremendously in the last few decades which in turn have made it much costlier in the long run. The savings keep on reducing while the number electrical appliances in homes are on a rise; in this situation going for solar water heater can prove to be an excellent choice for cost cutting and sustainability. Solar water heater can be broadly classified into two different types: Active and Passive. They both depend upon the sun’s energy, but they have differences in their working mechanisms. This article will explain all about passive solar heaters and why it is a cost effective way to water heating solutions. The two basic parts of a solar heater are an insulated water storage tank and a solar collector. The solar collector is the one which heats the water and move it up into the tank. The storage tank is similar in design to a tank type electric heater and performs almost the same functions. A drawback of a passive system is its lesser efficiency, but it is more durable, reliable and when compared is less costly than an active one. They are generally available in two different varieties, one the integral collector storage (ICS) and the other thermo siphon system. The ICS system has the storage tank situated below the solar collector, in which the cold water flows, gets heated and then transferred to the storage tank for use. This is suited for tropical or hot weather climate where temperatures never touch freezing point; moreover this water heater is practical for daytime and evening use. The thermo siphon is a bit different than the ICS system as it keeps the storage tank above the solar collector tubes and relies on natural physics that hot water being less dense rises up and cold water sinks. The cold water leaves the base of the tank and moves into the tubes where it gets heated and rises up into the storage tank. It is suited for moderate climates and also for day and night use. Solar heaters are a very reliable and economical source of hot water, but they also rely on the Sun for their working. On days when it is way too cloudy or additional amount of hot water is required, calls for a backup...

Solar Water Heater – Heat Water with only the power of the Sun

Posted by on Jan 11, 2014 in Posts

When we think about solar energy, the first thing that comes to our mind is harnessing the power of the sun’s radiation to produce energy or heat water as required. A solar water heater consists of solar thermal collectors and a fluid system which runs through interconnecting pipes and moves the heat from the collector to the tank. The heated water available from these heaters can be used for business and domestic purposes and save a fortune in the long run. Common places where solar water heater is perfectly suited are under floor heating, heating of swimming pools and energy input for space heating and even cooling. While choosing a solar heater, there are certain considerations that should be made. The first and foremost is the amount of sunshine, the required usage and the type of solar water heater. It consists of the following parts Solar collector to absorb energy from the sun. Power source for backup. Pump and control valves. Hot water storage tank.   Solar collectors can be broadly categorized into the following types: Evacuated vacuum tube collectors which have a series of glass tubes to take in energy. Absorbing plate collectors which are simpler to build and have heavy thermal insulators and glass covering to prevent escape of heat. Integral collector type which combines a storage tank to serve the functions of both heating and storing in a single unit. One thing to know is all the solar heaters are mounted on to the roof top from where they supply hot water for domestic and business purposes. Manufacturers of solar water systems are plenty in numbers and they can provide precise information about local dealers and qualified installers. A solar setup once installed requires occasional upkeep and maintenance and has high initial costs, which can be covered up in a few years. A setup which has complexities and requires roof penetration should be installed and looked after by an experienced and certified contractor to avoid future complications. A solar heater and its parts carry a warranty between 3 to 10 years depending upon type and manufacturer. Ample information is available on the web; the manufacturer’s website provides all the information that is required. Knowledge and understanding of how a solar system works will always help to keep your home eco-friendly, green and a healthy aid to sustainable...

Solar water heater market seeing rapid development around the world

Posted by on Jan 11, 2014 in Posts

Economists and market experts have anticipated that the solar water heater market is going to grow rapidly and generate profitable revenues in the next few decades. All this will happen due to rising living standards, corporate profit and income, stricter sustainability norms and technological advances which in turn will make solar water heaters more economical and efficient. A solar water heater system can provide ample amount of hot water for a family’s everyday use at no extra costs such as fuel, electricity and maintenance expenses. Despite so many advantages, it is surprising to know that only 1% potential of the solar water heater is in use. Very few residential buildings are equipped with solar heater facilities and are reaping its benefits. This industry had an unstable beginning, but was brought back to life by solar investment tax credits and federal banks providing loans for the initial setup at reduced interest rates and other benefits for people who install a solar water heater. The utilization and use of solar water heater is on a rise around the world due to its easy reliability, durability, cost savings and eco-friendliness. One exceptional example is China, where the use of solar energy to heat water has risen to 63.9 million square meters in 2012 at a tremendous growth rate of 10.7%. China being such a huge country with the world’s largest population has seen such advancements; other countries should model its plans and make this world a better and greener place to live. Residential and home installations account for more than 80% of the revenue collected by solar system manufactures and the wellbeing of this market completely determines the future of the solar industry. The industry was impaired during the last five years as a result of the decline in the number of residential houses and falling renovation rates. The decline in the number of new homes built created very few opportunities for solar water upgrades, which disfavored the existing homeowners to go for a solar thermal...

One of the cheapest way by which we can get hot water is by installing solar domestic water heater. It is also known as solar water heater only. It absorbs heat which is coming from the sun and transfers it to the water to make it hot. It is a cheaper way to get hot water because in other means you have to pay for it. How solar water heater works The water heater consists of a container which is painted black in color. The concept behind painting it into black is that black is a good conductor of heat and absorbs heat instantly. As soon as the container is warm, the water which is present in the container is also heated up. It is little time taking process but is efficient. In present scenario solar panels and solar cells are used for better performance. In the modified system there are many new things that are installed like insulated storage tanks, pumps, anti-freeze value and as well as solar heaters. The new system helps to heat up water in a faster way because it absorbs more heat from the...

There are a lot of expenditures which is related while heating hot water. A person will either use gas or diesel or any other combustible resource which is very costly and their price in increasing day by as the resources are going down in quantity. So to overcome this problem people from all over the world are opting to find an alternative method by which they can get hot water that too in minimum expenditure. The example of such method is solar thermal. It is an effective way by which a person can avail the facility of hot water free of cost as the energy which is used to heat water is coming from the sun. There is only one time installation charge in this process and a person can enjoy a hot water facility absolutely free. There is hardly any maintenance charge present in it as well. So in the long run it proves to be a better option. The solar hot water system contains three important parts. They are solar collectors which are used to trap the energy from the sun and use it to heat water, Solar tank which contains water that is needed to be heated And circulation system which helps to mobilize the water which is cold and to supply to different parts where required. Solar collectors are also known as solar panels. The panels are of two types Evacuated tube and flat plate. The main motive of collectors is to absorb the heat from the sun and pass it into the water to make it hot. It is preferred to have some measures to reduce the power consumption before switching to any alternative heating system. There are many ways which are present by which a person can reduce their monthly bills. For an example fixing leaky hot water is one of the efficient way by which money can be saved and new heating system purchase can be reduced. There is a sort of investment which has to be done for the installation of solar water heating system but in the long run it is beneficial and tax incentives and utility rebates help you to pay back the money rapidly. On the top of it solar thermal systems do not consume much electrical power to run the pumps, which are required to mobilize the hot water. The electronic controls and technology is very beneficial without any share use of current. It is capable to provide us hot water without any sort of damage done in the environment keeping it free from air, noise as well as water...
