Cold water comes into a compartment, gets warmed up to a certain degree, by the heating element and then the heated water is carried out through another outlet. There are a lot of water heaters out there in the market. Crompton is one of the leading players when it comes to geysers and water heaters. Whether it is a tank geyser or an instant geyser, Crompton is a master at both.
