The Anu Solar 300 LPD FPC Pressurized Solar Water Heater is a flat plate collector system rated to 8 bar, built for homes running a booster pump. Three collector panels heat a 300 litre tank, sized for 6 to 9 people, with a 3.5 mm galvanised iron tank, a sacrificial anode rod rated to 600 ppm water hardness, and a 5-year warranty on both tank and panels.
If there is a booster pump on your terrace, this is the model you need, and most of the cheaper 300 LPD options you have been comparing will not work in your home. That one fact decides this purchase. Rated to 8 bar, this pressurized solar water heater holds up against the force of a pressure pump and delivers hot water at the same pressure as the rest of your plumbing, so the shower stays strong when you switch from cold to hot. A gravity-fed heater in a pressurized home either underperforms from the first week or fails outright, and by then it is bolted to your roof.
A 300 LPD solar water heater at this capacity serves 6 to 9 people, which is a large family or a household with several bathrooms running in the same morning window. Because it is pressurized, it does not depend on your overhead tank sitting high above the terrace, which is what makes it workable in homes where gravity feed was never an option.
The flat plate collectors are the older, simpler technology, and for most homes they still make sense. An FPC solar water heater absorbs sunlight across the full panel surface and performs reliably in strong direct sun, lasting fifteen years or more with almost no maintenance. There is no glass tube to crack. The honest tradeoff is that on cold early mornings and through heavy overcast, a flat plate solar water heater warms more slowly than an evacuated tube system.
The tank is built heavy rather than coated. Galvanised iron at 3.5 mm thickness, with a sacrificial anode rod fitted to fight hard water up to 600 ppm. The anode rod corrodes so the tank does not, and it can be replaced during servicing. The outer tank is galvanised and powder coated to survive years of sun and rain.
One thing to be straight about: 600 ppm is the ceiling. If your borewell water runs harder than that, and much of India's does, Anu's glass-lined ETC range is rated to 2000 ppm and will outlast this tank. Tell our team what you know about your supply and we will tell you which one you actually need. Pointing you to the right tank costs us a sale today and saves you a replacement in four years.
Two things to confirm before ordering. Your terrace needs at least 9 feet by 10 feet of clear, unshaded space, and three flat plate panels take a large footprint, so measure it rather than estimating. And confirm you genuinely have a booster pump, because if your system runs on gravity from an overhead tank, the non-pressurized 300 LPD is the correct and cheaper choice. An electrical backup coil is available separately for cloudy stretches, ask our team whether your usage needs one.
The price includes transportation to your house, lifting to the terrace, and installation. You arrange the plumbing connection.
SolarClue is India's managed solar marketplace. Our team confirms whether your pressure setup matches this model, whether 300 LPD suits your household, and whether your water hardness suits a 600 ppm tank, 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.
