FAQs - Solar Water Heater
1.Is it very expensive?
When compared to an electric heater the Venus solar heater may sound slightly expensive. But a solar heater will pay back its investment in 2 years, through recurring energy savings.You may also be eligible for rebates on your electricity bills in some States
2.What could happen if water supply is irregular?
Incase cold water supply is interrupted during the day , the heating of water by the solar system may not be affected significantly, although hot water cannot be drawn for use till the water supply is restored.
3.Will I get power and hot water from this system?
No, Solar hot water panels only heat water. They do not generate electricity from sunlight. As the sun hits the glass tubes in the panel, water gets heated and flows back into the tank. Solar electric panels are made of silicon and convert sunlight directly into electricity. They are different from solar hot water panels.
4.What will happen on cloudy days?
The VTC model solar water heater will continue to function even on cloudy days due to heat absorption from the infrared rays of sunlight. Efficiency would be affected, however, on rainy days.
5.Can I get hot water during early morning when sun is not there?
Hot water produced by the solar system during the day is stored in an insulated storage tank. The insulation of the tank is such that the water remains hot without significant drop in temperature for around 24 hrs. Thus water heated during the previous day is available for use the next morning.
6.What are the Maintenance requirements?
Venus VTC solar water heating systems do not need significant maintenance. The collector tubes may need annual cleaning to remove accumulated scale and sediment deposits at the bottom. The system is resistant to adverse effects of weather as it is made of stainless steel.
7.Can I use Hot water from the solar water heater in the evening or night?
Using the Hot water in the evening or night will result in hot water being unavailable the next morning as the system will not heat water overnight. If you wish to use hot water in the evening too, then choose a larger capacity of solar water heater that meets your needs.
8.What is the expected life of a solar water heater?
Venus VTC solar water heaters can last for 15-20 years depending upon the general upkeep.
9.How do I decide about the size/capacity of the system to be installed?
For a house with one bathroom and 3 to 4 members, 100 liter per day capacity system should be sufficient. For more numbers of bathrooms, the capacity will increase accordingly due to pipe losses & more number of family members. Generally the capacity is decided based on hot water required in mornings for bathing. If the usage is in evening & at other times also, the capacity is decided accordingly.
