INTRODUCTION TO VENUS (VTC) ADVANCED TECHNOLOGY
We at Venus believe in bringing the benefits of the latest technology to our consumers. Now, in Solar Water Heaters too Venus introduces "Vacuum tube collectors" for the first time in India. Internationally renowned & accepted, this technology is superior to other prevalent systems in performance, reliability & ease of installation. Breakthrough technology that taps the unlimited power of the sun to give you enormous energy savings year after year.
Working of Venus VTC Solar Water Heaer
The Venus Vacuum Tube Collector solar water heater is made up of rows of parallel, transparent glass tubes. Each tube consists of a glass outer tube and an inner tube, or absorber, covered with a selective coating that absorbs solar energy well but inhibits radioactive heat loss. The air is withdrawn ("evacuated") from the space between the tubes to form a vacuum, which eliminates conductive and convective heat loss.
The Vacuum tube collector absorbs the heat from the solar radiation & heats up the water stored in the system through the Thermosiphonic effect.
What is Thermosiphonic Effect
A thermosiphon system relies on warm water rising, a phenomenon known as natural convection, to circulate water through the collectors and to the tank. In this type of installation, the tank must be above the collector. As water in the collector heats, it becomes lighter and rises naturally into the tank above. Meanwhile, cooler water in the tank flows down pipes to the bottom of the collector, causing circulation throughout the system. This is called Thermosiphonic Effect. This process continues steadily for a numer of hours till the water stored in the tank is heated up.
FEATURES
Heating from infrared rays of solar radiation
Greater absorption area per day

| Total cost of a solar water heater | Rs.24350/- |
| Cost of Electric Water Heater * | Rs.14,500/- |
| Difference | Rs.9850/- |
| Annual Saving **in Electricity | KWH 900 units * Rs 5 |
| Annual Saving **in Electricity | (Rs.) Rs.4,500 |
| Pay back Period*** | 24 Months |
* One 100LPD Solar Water Heater replaces 2 Nos. 25 Ltrs. Electric Water Heater
** Calculated at tariff rate of Rs. 4.50 / KWH assuming usage of solar Water Heater for 300 Days / Year. Energy consumed =3 units / day = 900 units / 300 days
*** Pay - back period = Rs.9850/ Rs.4,500 = 2 years = 24Months
