Geyser repair

If you are planning to buy a new water heater or geyser for your home, you’ll discover that you have more choices than before so it’s worth doing your homework.

7 important points to keep in mind while purchasing a geyser or water heater are:

Requirement (Family size)

Buy the right sized geyser as per your requirement. An over-sized geyser means heating extra water that is not required. Choose the size of geyser as per the size of your family and consumption habit geyser so that electricity is not wasted.

Longevity and parts availability 

Buy a geyser that has a longer life and has easily available replaceable parts. For example a tank-less water heater’s life is of 20 years approximately, compared to 10 to 12 years for tank-type water heaters.

Energy consumption

A 5 star rated geyser consumes less electricity for heating water as well as has much less heat loss. Install energy efficient star rated geyser and reduce your monthly electricity bills. Higher star rating geyser is little expensive to buy at the first place but they save a lot of money over longer time period.


Warranties are very important. Do not forget to check the warranty on heating element and tank while purchasing the geyser.

    I was looking to buy a new geyser and read this wonderful article. It’s crisp and to the point. If you write some more on the space constraints in the apartments and availability of horizontal and vertical geysers, that would certainly add more value to the article. More power to you Divya.

    Safety from electrical faults / leakage is perhaps the most important and the most ignored aspect. In wet conditions few seconds of small current in milli amps are enough to cause a death. Safety features in this regard need attention by manufacturers as well as experts advising on this subject. Use of an RCCB or RCD is recommended on electrical circuit dedicated to geyser’s electrical lines. More info can be accessed on European electrical regulations and brochures of big manufacturers like ABB, Schnider etc.
