A solar water heater is an alternative method of heating water. Instead of using the power grid it converts solar energy and uses it efficiently for the purpose of water heating. One can use this system independently at homes, with an efficiency of saving energy. The solar water heaters in Ahmedabad may use the same concept as a solar panel that provides electricity however, it has a different design. Solar water heaters are very efficient and can produce enough hot water to satisfy the needs of an average household. They are usually also equipped with a backup system that can utilize the alternative source of energy to heat the water. This article describes the working of a solar water heater and the risk of it being damaged while in use.
Working of a Solar Heater
This system uses the energy of the sun to heat the water directly using the intense rays of the sun. The fact that the sun is extremely hot (over 5500 degrees) is the reason we stay warm on earth. The added advantage of this intense heat is that it can be used for industrial solar panels and solar water heaters. Solar energy is rapidly replacing the convention source of energy in India and being used in many different applications like heating water as well as providing electricity to a house.
A solar water heater will consist of a storage tank and solar collectors. It can either used for residential water heaters or commercial. In fact, industrial solar panels and water heaters are very useful in reducing costs and improving the carbon footprint of a business.
A solar heating system has two different heating options. It can be an active system or a passive system. The direct system allows flow of the water via the solar energy collectors and heats the water in the process. It then flows into your faucets and showerheads. On the other hand, an indirect active system will use a warming fluid to transfer heat from the collectors the water supply. The passive solar heaters a metal plate to heat water in small batches. Once the water is heated it is moved to an insulated storage tank for later use.
Risk of Damage
A solar water heater is safe to use and durable. However, like every other heating machine, it too requires maintenance on a regular basis. The tasks of inspecting the solar heater equipment does not require a great deal of technical experience and can be carried out by anyone. It is necessary to take the help of the expert technicians for repair, replacement or general maintenance of the heating system. Some of the common issues include scaling, corrosion and freezing but does depend on climate conditions. The other issues of a solar water heater include heat loss, faulty sensor wires, issue with the thermostat, and flow blockage in the collector or low pressure. The buildup of minerals can also be an issue as can be broken elements and loose panels.
Some of the common solutions that the professionals implement for these problems include:
- Using insulation blankets for the pipes and seals at the joints, tank as well as pipes.
- Tighten any loose connections, clean & seal any exposed areas and make sure the wires are connected in the right manner during routine maintenance.
- Regular maintenance will also include checking the thermostat to make sure the setting is fine and no components need replacing or there is no leak.
- Flush the system if the flow is blocked in the collector or if the system pressure is high.
