I brought solar water heater 150 ltr in 2016 and the same is not working now. They told me that it has 5 years warranty on product but it is observed that the Tank is not covered in 5 year warranty. In warranty card they says it have only 3 years warranty. All most all vguard products are manufactured on contract basis and due to this the quality is very very poor. By spending Rs. 32, 000 the water heater is not working even for 5 years. Vguard is asking 9500 Rs to replace the water tank. So stay away from VGuard products and be safe. if any one requires proof I can give.
