The V-Guard TruHot GLO-ZA GL 500 LPD ETC Solar Water Heater is a large-capacity evacuated tube system with a glass-lined-coated tank, sized for 12 to 13 people, carrying a 10-year tank warranty. It uses 31 tubes (2100mm each) to heat a 500 litre tank, protected by a sacrificial anode rod and rated for water hardness up to 1000 ppm. It is a gravity-fed, non-pressurized system.
Capacity for a joint family or establishment. At 500 litres, this serves a joint family, a PG, a hostel, or a guest house where 12 to 13 people need hot water in the same morning window. Thirty-one evacuated tubes feed the tank the largest configuration in V-Guard's ETC range.
Two layers of hard-water protection. The inner tank is glass-lined-coated at 1.6mm, and a sacrificial anode rod sits inside it, corroding in place of the tank. Together they handle water hardness up to 1000 ppm and support the 10-year tank warranty. On a 500 litre installation this matters more than on a small one: replacing a corroded tank means dismantling a 31-tube array off a roof, which is an expensive and disruptive job you want to avoid for as long as possible.
The V-Guard name. V-Guard is one of India's most trusted home-electrical brands, with a service network that matters when a 10-year warranty on a large installation means someone actually turning up.
Evacuated tube heating. Each of the 31 tubes holds a vacuum layer that traps heat like a thermos, so the system keeps producing on cold winter mornings and overcast monsoon days when a flat plate system slows. For an establishment where many people bathe in the same window, that consistency is what matters.
A compact footprint for the capacity. This unit needs 8 feet by 8 feet of clear terrace space modest for a 500 litre system, which helps on a rooftop that also carries tanks and other equipment.
On hard water. At 1000 ppm this handles moderately hard supply. If your borewell water runs harder as parts of Bangalore and Hyderabad do a tank rated to 2000 ppm like the Sudarshan Saur range, or Supreme's higher-rated units, will outlast it. On a 500 litre system where replacement is a major job, getting the tank matched to your water is the most important decision in the purchase. Tell our team your water hardness and we will confirm.
Two things to confirm before ordering. Your overhead tank or Sintex must sit at least 6 feet above terrace level, because this runs on gravity. And if you have a booster pump on your terrace, this product is not for you — you need a pressurized model. Send our team a photo and measurements of your terrace and we will confirm before you spend anything.
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 500 LPD suits your household or establishment, tests your water hardness against this tank's rating, and checks your terrace and tank height 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 V-Guard warranty support afterwards. Compare the V-Guard TruHot against Supreme, Sudarshan Saur and other large-capacity heaters on our platform, and check the current solar water heater 500 ltr price.
