Good service and response by "Varsha Enterprises Complete Water Solution, Kalkere". I purchased the solar water heater of capacity 200 liters from them. By next day they visited and installed the product in my home. The total cost of the product is Rs. 19000 which includes for installation. I suggest this dealer to others who are looking to purchase a solar water heater. I'm satisfied with the reasonable price and good service by the dealer.
