I bought this v guard vereno 15 L water geyser last winter for heat water cold water make you get in fever so I bought it after its warranty it heat up to 40 degree Celsius with control because its controlling is not work properly and it take half hour for heat water . we call customer service of this company but no one received our call so we call our local mechanic for this and it said that this is worst product you have not purchase this because now market has more and powerful products than this product so guys you want to buy geyser then purchase better product and company too.
