Today we will learn about Evacuated Tube Collectors ETC Solar Water Heater Pros & Cons, Its price and Working Principles, solar water heater manufacturers in India, and some more faq about this topic.
With fast-paced technology, solar water heaters have emerged as a new designed & innovative style that helps in the conservation of energy and provide heat efficiency. Even so, improvements are still being made to maximize the efficiency of water heating. A recent development in solar technology is the evacuated tube collector. With time, ETC solar water heater has gained popularity due to their exceptional performance and attractive appearance.
When ETC heaters are compared with traditional water heaters, there comes a list of several advantages it offers to residential as well as industrial uses. With ETC heaters, the conversion of electricity into solar hot water initiates a reduction in electricity bills by 80%. For the best quality solar water heaters, Sun Stellar manufactures credible & efficient heaters with maximum life span and durability.
One of the most popular and used water heaters is ETC solar heaters, which consist of long paralleled tubes. It has various sealed glass tubes which allow high thermal efficiency. These are cheap and easy to install. If you’re looking for an effective solar water heating system for your use, evacuated tube collectors are one of the best choices among traditional water heaters.

How does ETC Solar Heater work?
ETC Solar water heaters have long parallel single or double sealed tubes which are 10 or more in number. These are made of glass or plastic and connected at the top by an insulated collector. Each tube is made of a copper pipe, which enhances the ability to absorb solar energy. The heat pipe is attached with a copper fin known as an absorber plate. A heat transfer fluid is a heater inside the heat pipe which vaporizes and comes at the top while it cools down & liquefies.
Under this process, the heat is released, and the heated fluid flows to the heat exchanger where it gets heat from the tubes and transfers it to the water storage tank. A large amount of heat energy is released into the storage tank, thereby making water hot. In the case of a single evacuated tube collector, the absorber plate and the heat pipe are located in the vacuum whereas, in a double tube, the vacuum is located between the glass. The surface material absorbing the solar or sun heat energy enables the system to work efficiently and enhance the solar water heater performance.
Additionally, the tubes also known as vacuum tubes remove the air from plastic tubes as soon as the vacuum is created, which reduces the loss of heat energy. Due to a reduction in convection and conduction loss, the ETC solar water heater works efficiently and performs better even at higher temperatures.
Pros of ETC Solar Heater
ETC solar heaters are considered the best solar water heating system, which works better than a flat-type collector. Not only do they perform effectively in colder temperatures, but even they provide equal performance in warmer temperatures. Due to their higher heating efficiency, they are usually used in northern regions where there is cloudy or cold weather. Additionally, the vacuum tube also aids in eliminating the condensation in the collector alongside retaining heat energy inside the tube. The elimination of air inside the tubes generates excellent insulation while allowing higher temperatures as compared to any other solar heater. With ETC heaters, water freezing problems are reduced to zero.
Cons of ETC Solar Heater
Along with some benefits, ETC solar water heater also contributes to certain disadvantages. Though these are considered good heat insulators, in case of snow accumulates on the tube, it does not melt and sticks on the top & between the tubes. Sometimes, the snow is stuck the whole time in the water, which lowers the performance and ability to capture the sunlight. Moreover, these types of water heaters are also sensitive and require thorough maintenance. Due to their thin tubes, they are more prone to breakage and thus, require constant replacements.
Conclusion & FAQ
It is always beneficial to look after the requirements and compare them with the pros since it is crucial to saving electricity and energy while generating abundant hot water. With an ETC water heating system, you can achieve both. Choose Sun Stellar for high-quality solar water heaters that work better & effectively.
