    12)
    What are the basic rules to judge a good water heater?
    The efficiency of solar water heater depends on its collector area and material used in their making. 1 meter square of collector made of good material can heat up to 50liters of water on a bright sunny winter day in northern parts of India. A standard water heater usually has 2sq.m of area and can heat almost 100 LPD. Also ensure that the absorbers have good quality coating and have BIS approval.
    13)
    What is FTC ?
    FTC stands for Fixed Temperature Control.For larger LPD hot water requirement,additional force is needed to push the hot water collected in the solar collector. The FTC control monitors the temperature at the outlet of the collector. If the thermal difference is more than the SET temperature the pump gets switched ON. If the temperature falls below the SET temperature, the pump gets switched OFF automatically.
    14)
    What is LPD? Why do solar water heating systems carry this term?
    LPD stands for Liters per Day, which specifies the daily capacity of a solar water heating system. The solar water heater capacity cannot be defined in hourly terms as the solar radiation keeps varying throughout the day.
    15)
    Is it true that ETC (Evacuated Tube Collector) Technology is better than the FPC(Flat Plate Collector) Technology?
    The ETC technology is relatively new and hence more advance when compared to the FPC technology. However, FPC technology is cheaper and offers significant cost savings. Recent years have seen lots of advancement in solar technology and ETC is also becoming cheaper
    16)
    We have a large house with usage points on different floors in a scattered manner. How would you plan the solar water heater for us so it minimizes wastage of hot water in pipeline?
    If you have a large house and the usage points are scattered we suggest having smaller water heaters of various capacity installed at places nearest to the usage point. This would minimize piping cost and also reduce wastage of hot water in pipeline.
    17)
    Will I need additional geysers after installing solar water heater?
    Solar water heating system has built in system for conventional electricity back up. This means you do not need additional geysers after installing a solar set up.
    18)
    What if the tube breaks? Can it be replaced by a regular plumber or me?
    Please inform the installation company as soon as you notice a broken tube. We recommend to get it replaced by an expert team instead of a general plumber. To stop water leakage from broken tube, please shut the inlet and outlet valves and inform the installation company so they can repair it asap.
    19)
    The standard sizes available are in multiples of 100. Can you make customized tanks also, say of 550 litres?
    We stock tanks in capacity of hundred and its multiples as it suits the requirements of all types of households ranging from small to big families. However if you have special requirements please feel free to contact our team at +91-80102-95295 and we would try to find a solution for you.
    20)
    Are the glass tubes robust enough to withstand strong winds or hail stones?
    Solar equipment undergoes severe stress tests and can withstand adverse weather easily. The glass used in these tubes is of very strong quality (boro-silicate glass) and can resist hail stones up to 1 inch in diameter. They can also withstand winds of 80 miles/ hour speed.
    21)
    What type of maintenance is needed in the long run?
    As mentioned earlier solar water heaters need minimal maintenance. ETC based solar water heaters require no additional maintenance apart from the panels being cleaned routinely. For collector tubes, we suggest annual cleaning to remove scaling and deposited sediments. This increases the system’s efficiency. AMC options are also available whereby you can opt for maintenance services on a prepaid basis at the time of installation.
    22)
    How does use of solar water heater help the environment?
    A solar water heater helps to reduce the overall carbon footprint of any family. For e.g.; if you install a 100 litre system, for your family of 3-4 members, it would reduce the total carbon emissions by 0.4 to 1.0 tonnes of carbon dioxide / year. This small step taken today would definitely go a long way in saving our environment for generations to come.
    23)
    I do not want to make major changes to my existing plumbing system. Can we integrate solar water heater in the current plumbing without breakage and damaging the aesthetics of my home?
    Solar water systems are very easy to install and can be integrated with any kind of existing plumbing systems without breakage. Our installation team works to make a detailed plan for any location and installs the tank nearest to the usage point to avoid long pipes.

    26)
    What type of maintenance is required by solar water heaters?
    Almost all solar products, including solar water heaters are No Fuss, Minimal or Zero Maintenance equipment. Simply ensure that there is no dust on the solar panels as it forms a screen and blocks sunlight. Wiping the panels once every 5 days is all you need to do. However, you can wipe the solar panels everyday as it would certainly boost the efficiency of the system. Also ensure that the main cold water tank supplying water to the solar tank is always filled optimally. Using automatic level controller can help you achieve this easily.
    27)
    Is it very expensive?
    Compared to an electric heater, a solar water heater’s upfront price is slightly higher. But it requires ZERO electricity and the daily savings on electricity bills pays back the initial investment in 2-3 years. After this period you can have warm water year round for FREE. You may also avail subsidy and other benefits depending on your state’s policy on installation of solar panels/equipment.
    28)
    Does Solar Water heater work in cold climate and on cloudy days?
    It is a common misconception that solar water heaters might not work on a cloudy, foggy or cold day. Solar panels do work best when it’s is bright and sunny but even on cloudy and foggy days the solar panels are able to convert solar radiation into solar power which warms the water. Performance of a solar water heater depends on 2 factors: a) how cold the water is b) how much solar energy is available on the given day Solar water heaters need a conventional electric based backup system only during prolonged stretch of rainy days.
