Using hot water is probably as old as human civilization itself. We get evidence of the use of hot water for baths in the "hamamas," or the public baths of old civilizations. Since then, hot water has been accepted as a "preferred luxury" for men. In the present, an electric geyser has become a "fair necessity," mainly because of the odd hours for a bath or wash, which are quite common for urban men. Also, the use of showers is so widely accepted for its function and economy that the old time consuming method of heating water first and then mixing it with cold water to a proper temperature for a bath is done away with, wherever it has become possible.

Now there are two types of geysers available, that have the possibility of shower connections. First is the storage type, which has the advantages of a proper shower connection, multiple taps, low wattage, and higher safety. But it is gradually becoming prohibitive because of its high cost, difficult maintenance, large area requirements, and difficulty in installation. The second is called the instant type electric geyser. This is getting wide acceptance primarily for its low price, small space requirement, and ease of installation. But it has the drawbacks of lesser electrical and mechanical safety and a difficult shower connection. Naturally, a product is needed that can have most of the advantages of both, mainly electrical and mechanical safety, shower connection, low price, lesser space requirement, and easy maintenance.
