Evacuated Tube Collector Solar Water Heating Systems
High Energy Bills ??? Rising heating costs every year ??? Reduced Profits ??? Do you require
heating / pre-heating up to 85-degree Celsius ???
IF YES, THEN, USE Bhagwat Energy Pvt Ltd. Evacuated Tube Solar Water Heater - an unmatched and reliable solution to conserve energy. The Evacuated Tube Solar Water Heater use the abundant energy of the sun to heat water to temperatures as high as 85C and result in quantum savings in electricity or fuel oil.
The
solar water heater system is regularly paired with an electric water heater, which has 2 purposes: Heat up water on days that don't provide sunlight. Supplement heating the water in case it's not hot enough. ETC is one of the best water heating system where a different technology used by Evacuated Tube Collectors (ETC) which makes them highly proficient and operationally better-quality. The Evacuated Plates absorb solar energy and the vacuum between the two glasses insulates against heat loss. ETC based solar water heater do not need significant maintenance.
Water heated by the sun can reach temperatures more than 212° F, but the usual temperature for household use is only 120° to 130° F On cloudy days solar energy can easily reach those temperatures.
In the winter
solar heater didn’t get generated. Nearly all of your hot water will be solar heated from April through September.
You will need a conventional backup system during the rainy season.
Solar Water Heater is available in LPD(liters per day)

How Does it Work?
A solar water heating system consists of a suitable collector and an insulated hot water storage tank. Solar Water heating systems work on the principle of `Thermo-Syphon'. Hot water, lighter than cold water, heats up and rises in the collector naturally to the hot water storage tank. For larger systems, the hot water may be 'force circulated' between the collector and the hot water tank.
All glass vacuum tubes is the key component of the evacuated tube collector. Each evacuated tube consists of a 'tube-in-a-tube'. The outer tube is made of extremely strong transparent borosilicate glass that is able to resist impact from hail up to 25mm in diameter.
The inner tube is also made of borosilicate glass and coated with a special selective coating. The coating has excellent solar heat absorption and minimal heat reflection properties. The vacuum between the concentric tubes eliminates conductive and convective heat losses from the inner to the outer tube.
Due to the round shape of the evacuated tube, the amount of solar radiation striking the collector is relatively constant from mid-morning to mid-afternoon. As the sun rays are incident on the tubes at right angle, reflection is reduced. A reflective backplate reflects back any light that passes between the tubes or reflects off the tubes, by the reflective back panel, radiation is therefore maximized.
