Solar Water Heater
We can use sun’s 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.
Let us understand the make up 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.
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. It’s 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.

One of the major advantages of solar water heaters is that they are non-polluting and prevent the emission of carbon dioxide to a large extent. Once you have got your solar water heater installed, you can stop worrying about the return on investment. The pay back period ranges from 3-6 years depending on the fuel you were using earlier, how you utilized your new solar water heater and its location. So, if you want to be a wise money saver and believe in using environment friendly products chuck your old water heating devices and get a solar water heater now!
