ETC solar water heater dimensions, specifications, and how they operate
What we want to discuss today is the ETC (evacuated tube collector) type of solar water heater and its respective dimensions, specification and in general, we want to say how do they operate in the water treatment process.
ETC solar water heater
A solar water heating system that makes use of evacuated tube collectors (also known as ETCs) makes use of efficient solar collector technology.
It does this by utilizing conductive glass tubes that soak up heat from the sun and then transfer that heat to the water or other fluids that are moving.
A series of glass tubes, often constructed out of borosilicate or soda lime glass, make up the components of an ETC.
Thermally conductive copper rods are contained inside these glass tubes that have been sealed.
The glass tubes are held aloft by a frame and are organized in a configuration that resembles parallel lines. Each tube consists of a substantial outer tube and a more elongated, narrow inner tube.
A vacuum is formed by removing the air from between the inner and outer tubes of the device. This process of removing air is where the term "evacuated tube" gets its start.
The vacuum has an insulating effect on the system, which makes it more difficult for heat to escape. Because of this, an ETC solar water heater can create fluid temperatures that are greater than those produced by other solar water heaters such as the FPC (Flat Plate Collector).
The coating on the tubes is designed in such a manner that it prevents heat loss while at the same time absorbing heat.
The copper rods and the evacuated tubes that they contain are linked to a heat exchanger. This allows cold water to enter the heat exchanger, where it is heated by the evacuated tube, and then flows out as hot water to an insulated storage tank. Even after the sun has set for the day, you may still make use of this hot water.
The following are some of the reasons why ETC solar water heaters are more cutting edge and effective than their competitors:
Because of their tubular construction and the fact that they do not contain a significant volume of water, they take up significantly less room than other containers.
The sunlight is always directed in a direction that is perpendicular to the tube because it is cylindrical in shape.
Because of this, the collectors continue to function well even when the amount of sunlight available is low, such as in the early morning, evening, or overcast days.
ETC solar water heater specification
An ETC solar water heater can heat water too fairly higher temperatures on days when the atmospheric temperature is low.
This means that you will have access to hot water even on days when the temperature of the atmosphere is low. This is because the vacuum does not support the loss of heat.
Solar water heaters made by ETC are suitable for both residential and commercial use. Sunshine Solar is one of the leading ETC solar manufacturers in Karnataka; as such, we can assist you in determining your requirements and tailoring your ETC solar water heater to meet those specifications.
We think that this is true for Sunshine's most recent introduction, the "Lazurite – Marine line," since it is thought that the Lazurite gem bestows its users with a very large number of benefits and that this is consistent with the gem philosophy.
The installation of a solar system is currently a must, and so is the routine maintenance of the solar tank. The recently introduced technology from Sunshine Solar Systems is designed to assist you in doing these tasks.
By utilizing a marine line, you can be guaranteed a clean and sanitary water storage system. Additionally, a marine line that is settled stably on the tank does not melt even during a scorching summer since it becomes heat resistant. The solar tank is uniformly covered with specially made lazurite.
The following are some of the reasons why you should use lazurite marine line:
Because of the marine line's consistent thickness, the temperature of the water is maintained at a high level for an extended period.
Your tank won't rust or corrode thanks to the protection provided by the marine line.
It does not harm the environment, it is completely safe, and it can handle any kind of water. The surface of the water tank will not become contaminated with chemicals, salts, or other contaminants as a result of this feature.
Your skin and hair will not be damaged if you drink water from a tank that has been covered with a marine line.
It comes with a warranty that lasts for ten years and guarantees a continuous supply of sanitary and clean hot water. You will no longer see any leaks in your tank as a result of the leak-proof features of the marine line.

The ETC kind of solar water heater is now the most popular choice, and there are a lot of good reasons for this. The primary reason for this is that Glass Tubes are used as Collectors, which results in lower prices.
Because there is no clogging or corrosion of glass tubes, there is no need for maintenance.
works effectively in the presence of hard water.
Lightweight
can be disassembled or reassembled in the span of twenty minutes.
simple to replace broken glass tubes with new ones
The cost of tubes is fairly reasonable.
ETC solar water heater operation
Although the ETC solar water heater is only intended for use with water of normal pressure, certain manufacturers do make models that are suitable for pressured water (the cost will be slightly higher for this). At the moment, we only apply it to water situations that have typical pressure.
The following are the bare necessities that must be met to install a solar water heater of type ETC.
Terrace space with no overhanging trees
The needed space for a solar water heater of 100 liters was 6 feet by 8 feet.
The height of the overhead tank should be at least 5 feet as measured from the level of the terrace.
Make sure that your hot and cold plumbing pipes are ready before you install a solar water heater.
The majority of companies that sell solar water heaters won't take care of the hot and cold water plumbing works for you; if you need it, you'll have to pay an additional fee. Before you go ahead and buy the thing, you should discuss this with the vendor first.
Only after eight or nine in the evening should the solar water heater have any water added to it for the very first time.
This is of the utmost importance since the ETC tubes would shatter into many pieces if the water is allowed to enter during the day.
Because there will be neither a guarantee nor a warranty attached to ETC tubes, you must exercise extreme caution
Maintain communication with your plumber before he begins the task. After the water has been brought to the proper level, there should be no further issues.
Maintain a clean environment for the glass tubes so that they may take in more of the sun's heat.
The technique known as evacuated tube collectors (ETC) is a type of solar collector that is known for its high level of efficiency. This technology makes use of borosilicate glass tubes to absorb heat and then transmit that heat to water or other flowing fluids.
Superior Efficiency
94% sun tracking from dawn to dusk, and with vacuum insulation, there is no heat loss even in the coldest temperatures.
Reliable
No scaling or corrosion due to borosilicate glass
Simple upkeep and repair
Glass and the tank system may be cleaned quickly and easily on-site.
