Solar Water Heater
Solar water heater is solar power based equipment that is extensively used in several sectors. Their main benefit that has made them so popular among the masses is that they help save up a lot of time and money. Water heaters are very frequently used especially in winter season. These solar water heaters are very good substitutes for electric water heaters as they heat up the water in the most natural way. Solar water heater is used in many sectors ranging from hotel industry to other industrial sectors where hot water is required. We can use sunís energy in a lot of ways for our benefit. Solar powered products like solar water heaters help us achieve this potential at no cost at all.
Process Steam Generation
Our trough systems can be used to support almost any kind of thermal load for industrial or commercial applications, including:
- Steam Generation
- Process Hot Water Production
- Industrial and Domestic Hot Water Heating
- Food Processing (Washing, Cleaning, Cooking etc.)
Let us understand the make up and working of a solar water heater. The solar energy gets accumulated with the help of a collector. It consists of a solar panel with a selected coating that absorbs the heat and transfers it to the riser pipes underneath it. The temperature of the water being circulated in the pipes rises up and gets stored up in a tank. The storage tank is insulated to maintain the temperature of the water.
The climate of a region and location are the deciding factors in choosing the solar water heater suitable for your use. Warmer areas benefit from active systems with direct circulation whereas colder climates require indirect circulation which makes use of a heat transfer fluid. For rooftops you can install passive systems where city water pushes the heated water to the outlet and storage is the collector itself. One can also go for the thermosiphon system where the storage tank is placed above the collector and gravity pushes the heated water.
Changing weather condition, limitation of space, amount of sunlight available or the capacity are some other factors that can influence your choice for buying a solar water heater. The solar water heater price also depends upon your water requirements per day.
Heating water through electric water heater is the most artificial method which in the long run is not beneficial for the health while water heated through solar water heaters is very natural and is blessed with sunlightís best vitamins that help spurt our growth process. Solar water heater is usually mounted horizontally over the solar collectors placed on the roof top. This method does not require any type of pumping. Once the water is heated it automatically rises in the tank through the process of thermosiphon. There are some solar water heaters that do require pumping systems. These systems are placed on the ground wherein its level of placement is below than that of solar collectors. As such the pump helps move the water between the collectors and the tank. These solar water heaters are designed in a way that they easily supply hot water through the year. There are solar water pumps which are also available in the market easily and save you a lot of time and money.
Also, as far as commercial usage of these water heaters are concerned, they are widely preferred in hospitality industry, hotels, dormitories and hospitals. These are also some of the places where heated water is much in demand and is regularly required in large quantities. Therefore, these industries highly rely on solar water heaters where these heaters act like a boon. These solar equipments also help save a lot of time of the working professionals at these places apart from helping them save a lot of money. In residential sector, the requirement however may depend upon the number of family members and the time of the year when hot water is required. Heater water may be utilized for bathing, washing clothes and cleaning utensils. Mostly it is seen that an individual requires about 35 liters of hot water for bathing purpose which make it approximately 125 LPD of hot water for a family of four. Depending upon the requirement of hot water, these solar heaters are equipped with the tanks of particular capacity.
Be it residential sector, commercial sector or industrial sector, the advantages of a solar water heater remain the same for all the three. These solar water heaters help save up a lot of money and cut down the monthly electricity bill by half the amount. Since the electric water heaters fetch a lot of electricity and thus result in increased electricity bill each month, replacing them with innovative and smart solar water heaters helps save that extra buck every month. Among those families that have these solar water heaters, some families end up saving a great deal of money while others do not save as much. This basically depends upon the region where one lives. The amount of sunshine that a particular area gets forms the basis of how much energy one saves by switching over to solar water heaters.
Apart from that, using solar water heater also helps reduce pollution level in the environment. These water heaters help cut down the carbon footprints by half as compared to the electric water heaters. Besides, using solar heaters gives a chance for helping the atmosphere get healed. As it is we have exploited non-renewable resources so much that there is no further going ahead to that, as such if we make use of solar power it only helps reduce further degradation of the environment. In the longer run, these solar water heaters shall help save a lot of money when the non renewable resources would have become a rare commodity to find and would cost a bank. Employing solar heaters also helps increase the value of the property which you can reap at the time of selling of the property. Once these solar equipments have paid for their price in a few years time, you will see yourself being cushioned to the increase in the price of fuels. At the same time this shall also give you a chance to act as a helping hand to reduce countryís oil dependence on other nations.
Types of Solar Water Heaters
Other types of a solar water heater are the flat plate collectors and evacuated tube collectors.
Flat Plate Collectors
Flat plate collectors have glass on top and have blackened metallic absorbers inside and riser tubes to carry water.
Evacuated Tube Collectors
Evacuated tube collectors are made of a glass tube where the outer covering absorbs the solar radiation and the heat generated is transferred to the flowing water.
After taking a look at the types of a solar water heater available in the market, one can decide which one would be best suitable for their homes. Similarly, during summers, one can choose from solar air conditioners and solar coolers. Itís an excellent option for saving your electricity bills by 50-80 percent and approximately 1500 units of electricity annually over the other conventional water heating alternatives like geysers of a capacity of 100 litres. Solar water heater has an average life of 15-20 years. Not only domestic but solar water heater is also used for commercial purposes such as hotels, hospitals, industries, dairies and enjoys a wider international market now. More number of solar water heaters can share the power load to a considerable extent. The temperature that can be reached with it is around 60-80 degrees.
