If you are a family of two or three looking at your first solar water heater, 100 LPD is the size that fits, and this is the model to start with. The Anu Solar water heater in this configuration uses a Flat Plate Collector, a single solar panel that absorbs sunlight and heats water directly, storing it in an insulated 100 litre tank so you have hot water ready when you need it, morning or evening, without touching your electricity bill. This is a non-pressurized solar water heater, which means it works on gravity. Water flows down from your overhead tank, through the system, and to your taps. It is the simpler, more affordable, and lower-maintenance of the two designs, and for most independent homes with a properly positioned overhead tank, it is all you need. There is no pump, nothing to fail, and nothing extra to run.
FPC is the right choice here for a specific reason. Flat plate collectors hold up well in Indian conditions and typically last 15 years or more with almost no maintenance. This unit's inner tank is galvanised iron at a substantial 3.5 mm thickness, with a sacrificial anode rod fitted to fight water hardness, rated up to 600 ppm. The outer tank is galvanised and powder coated to survive years of sun and monsoon, and Anu Solar backs both the tank and the panel with a 5-year warranty each. It is designed for a family of 2 to 3 people, running a single collector panel in a non-pressurized configuration, with an electrical backup coil available separately for cloudy days and monsoon.
A 100 LPD solar water heater is the entry point, so here is the honest sizing guidance. One hundred litres serves 2 to 3 people comfortably. If you are 4 or 5, step up to 200 LPD, because running short every morning for the next fifteen years is not a saving. And if your water is harder than 600 ppm, which parts of Bangalore and Hyderabad exceed on borewell supply, tell our team, since a glass-lined tank will serve you better than this one. We would rather point you to the right product than sell you this one.
Check three things before you order. Your terrace needs at least 9 feet by 4 feet of clear, unshaded space. Your overhead tank or Sintex must sit at least 6 feet above terrace level, because this system runs on gravity. And if you have a booster pump on your terrace, this product is not for you, you need a pressurized model instead. Send our team a photo of your terrace and we will confirm before you spend anything. The price includes transportation to your house, lifting to the terrace, and installation, and you arrange the plumbing connection.
SolarClue is India's managed solar marketplace, and we do not just list this heater. Our team confirms whether 100 LPD suits your family size, whether your water hardness suits a GI tank with an anode rod, and whether your terrace and tank height work for a non-pressurized system, before you pay anything. You book with a token payment rather than the full amount upfront. Delivery, terrace lifting, and installation are coordinated by us through verified partners, and we handle Anu Solar warranty support afterwards. Compare the Anu Solar water heater 100 LPD price against Supreme, V-Guard, Racold, and the other brands on our platform, and buy the one that actually fits your home.
