ETC SOLAR WATER HEATER

ETC Solar Water Heater is a Technology where Renewable Energy ie energy from sun is used for the conversion of sunlight into the heat for heating water by using a solar thermal collector. These Solar hot water systems are usually situated on a terrace or somewhere with plenty of sunlight. It heats water during the day, which is then kept in an storage tank and heated water is used whenever needed. The majority of the Solar Water Heater System is used in the residential sectors.

ETC SOLAR WATER HEATER WORKING PRINCIPLE

The Evacuated Tube Collector(ETC) solar System allows for high-efficiency solar energy absorption and utilization with minimal heat loss. ETC Solar Water Heater is composed of evacuated double-layer borosilicate glass tubes to provide insulation. These Tubes absorb solar energy from the sun and converting it into heat which is further used in heating water stored in the tanks passing through the tubes. Solar Energy is the most efficient use of renewable energy, provide hot water throughout the day without consuming expensive electricity. Sun Stellar is the Best Solar Water Heater Manufacturer in India. Heated Water Is Stored In The Insulated Water Tanks To Further Maintain The Water Temperature Attained With Solar Energy. Various Types Of solar water heating system Are Available As Per The Specifications.

FAQ's

solar water heater 200 ltr price?

Solar water heater 200 ltr price in India is 33930 Inr.Sunstellar manufactures and supplies solar water heaters for domestic and commercial use. They offer a line of high efficiency solar water heaters that combine quality engineering with competitive pricing.

Why should we opt for Solar Water Heating?

Solar Water Heater is a renewable energy device which uses Solar Thermal Energy to heat water which save electricity and thus money; electricity is becoming more and more expensive and its availability is becoming unreliable:

  • Solar water heaters are non-polluting.
  • Solar water heaters are safer than electric geysers as they are located on the roof.
  • Solar Water Heater gives hot water 24 Hours a day .
How do Solar Water Heaters Works ?
  • A typical domestic solar water heater consists of a hot water storage tank and Solar Collector of either Flat Plate Type (FPC) or Evacuated Tube Type (ETC).
  • The collectors are installed facing the sun – South direction to allow solar radiation to come in.
  • Water is heated because of high absorptivity of solar collectors.
  • Heated water is collected in the tank which is insulated to prevent heat loss.
  • Circulation of water from the tank through the collectors and back to the tank continues automatically due to density difference between hot and cold water (thermosyphon effect).
Why Should one buy Stellar Solar Water Heater ?
  • TEAM Stellar identifythe appropriate Collector Area required for Solar Collectors which results in fast heating of water.
  • Collector used in Stellar Solar Water Heaters are made with BIS Complied raw material and are technologically advanced .
  • Stellar Solar Water Heater customisses the Hot Water Tank as per water condition in your area which results in maximum life of system
  • Stellar Solar Water heaters uses Robotic and Automatic Production process to manufacture best in class systems.
  • Stellar Tanks are insulated with high density PUF Insulation to ensure minimum heat loss during night and winters.
  • Stellar Solar Water Heater Systems are mounted on best in class heavy duty Steel Structure which prevent any damage in high winds .
What is ETC in solar water heater?

ETC Stands for Evacuated tube Collector. ETC Collectors are the most efficient solar Thermal Collectors used for heating water. ETC Collectors are made of two borosilicate glass tubes with an inside coating of Copper and Alloy and an outside black color coating. The Second glass tube is used to create vacuum insulation so that heat is trapped inside the inner tube and there is no heat loss to the environment.

What is difference between FPC and ETC solar water heater?
  • FPC and ETC: These two solar water heaters are not the same. FPC is a newer type of solar water heater than ETC. FPC heaters are more efficient and more expensive to buy. FPC is more streamlined and looks more like a normal water heater. ETC heaters look like a regular storage tank with some extra black piping. Basically, the only difference between the two is that FPC heaters have a heat exchanger inside the tank. Other than that, there is no difference between the two.
What is a flat plate collector?
  • It consists of an absorber plate which is coated on its sun facing surface with an absorbent coating, also called selective coating.
  • The absorber consists of a grid of metallic tubes and sheets. Water flows through the tubes. Sheet absorbs the solar radiation falling on it and transfers it to water.
  • The absorber plate is placed in a top open box to protect it from weather. The space between back and sides of the absorber and the box is filled with insulation to reduce heat losses. The front of the box is covered with a high transmittance glass plate.
  • Flat plate collectors are specified on the basis of their area and are of commonly 1x2 m size.
What is an ETC Collector ?
  • ETC Stands for Evacuated tube Collector .
  • ETC Collectors are the most efficient solar Thermal Collectors used for heating water .
  • ETC Collectors are made of two borosilicate glass tube with inside coating of Copper and Alloy and outside black color coating . The Second glass tube is used to create vacuum insulation so that heat is trapped inside the inner tube and there is no heat loss to environment .
  • ETC Tubes comes in 2 Popular sizes – 58 MM Dia and 1800 MM Length and 58 MM Dia and 2100 MM Length .Each Tube is Capable of Heating 10 – 15 Liters of Water in one Day .
What would happen on cloudy days?
  • The heating of water by the solar water heater will obviously be affected.
  • If it is so cloudy that energy received from the sun is almost zero, the output of solar collectors also will be nil.
  • On partially cloudy days some output can be expected.
  • But, the system can be designed with a suitable electrical back up heater to take care of hot water demand on cloudy days.
How much Electricity and Money can be saved?

Depending on the Usage and geography Electricity saved varies . A standard 100 LPD Solar Water Heater System can save 2-3 Units of Electricity Each Day . Normally Solar Water Heaters can recover its Cost within 3 Years .

What are the Maintenance Requirements?
  • Domestic solar water heating system does not require significant maintenance. Occasional leakages in the plumbing could be easily repaired by common plumbers.
  • In case quality of water is hard, scale deposition in the collectors may result over the years. This may require descaling with acids for which it is best to contact the suppliers.
  • Broken glass may also have to be replaced by the suppliers.
  • If outside exposed surfaces are painted, the paint may have to be redone every 2-3 years to prevent corrosion of the surfaces.
