One year ago my electric worker came im winters to put point of heater in our washroom.we were confused which one to buy so we ask electric worker for the suggestion and he advice us to purchase venus water heater.since we had a big family we purchased 15 liters heater and installation was done properly, service was good and price was affordable.it get heat automatically once it is used.since one year we dont came with any problem, its working very nicely .ease of use is also very good.style and design is also nice and size its depend on your family size whether you buy 10 litres or 15 litres .if you have small family 10 litres is enough but if you have big family like us you need 15 litres like us.you can completely rely on this heater.it is the best one with reasonable price.
