Top Ten Water Heaters/geysers in India by standing loss and size

By on January 24, 2014

shutterstock_114199354 Although electricity consumption of water heater or geyser depends on the amount of hot water used (as discussed in our link: Choose the right sized water heater/geyser for electricity saving), standing loss can be an important factor while deciding which water heater to buy. “Standing loss” or heat/energy loss of a water heater to the surrounding in 24 hours is an important factor used by BEE (Bureau of Energy Efficiency) to decide on star rating of a water heater. Using hot water optimally and choosing the right sized heater can minimize “Standing Loss”, but the most efficient water heater for a given size can assist in minimizing losses. Most sources on the Internet provide details on features and reviews. Electricity consumption hardly becomes the deciding factor. To help people make electricity consumption as deciding factor, we at Bijli Bachao have decided to put up a list of Top Ten Water Heaters/Geysers in India by standing loss and size.



  • The basis of this ranking is the data from BEE (Bureau of Energy Efficiency). BEE data contains standing loss of a water heater and this information is self reported by the manufacturers. The data is calculated in test conditions.
  • We have taken the data on standing loss and categorized it by the capacity or volume of the water heater. The water heater with the least value of standing loss units/lts is given the highest ranking. Multiple models with the same value are given the same rank.
  • The list below contains only the top ten ranked water heaters. List of all BEE star rated water heaters are available on the useful links given below.
  • Use the ‘Add to compare’ icon to compare the monetary value of the units available from BEE based on your tariff from your electricity provider and your usage.
  • We regularly update this list as new models get added in the BEE list of water heaters.

    hello,..plz anyone can tell me how much maximum temp. attain in this commercial instant heater..because we gonna to use hot water for our project so it is important that how much we can attain…


    • Abhishek says:

      Hello mr Bhavik,

      It should be available in the user manual of your water heater. Typically water heaters have a default setting of about 60-65 degrees.

      Hope this helps.

    Hi abhishek

    I’m using commercial electricity in Bombay. I’m looking for a efficient 5ltr heater. I’m basically looking for my hotels bathroom. It will be used by 2 to 3 people a day. So u would suggest a 5ltr or 10ltr. In 10ltr I know ken star is good. So if you could suggest what should I get

    Kindly reply


    • Abhishek says:

      Hello Mr Hasan,

      For a hotel room I would suggest a 10 lts water heater. Because you do not know how much hot water will a person use in one bath. A 5 lts is good if someone takes a reasonably short shower. But if someone decides to take a longer shower, then 10 lts will be better.

      Hope this helps.


  3. Jigar says:

    I am searching for a good water heater/geyser which is economical and better in terms of energy efficiency. There are 4 members in a family. but we dnt have much usage of water.
    Please suggest me few options which are convincing in terms of energy savings and performance.
    I look forward hearing from you.
    Thank you.

    I live in Ahmedabad and we face hard water issue. I read your previous post to purchase a glasslined coated inner tank. So i have narrowed it down to either Bajaj Majesty 15L GPU or Bajaj shakti 15L V. Both are 5* rated and the spec are the same except former is a plastic body and latter is a metal body. Considering hard water issue which body type should i opt for? My heart is set on Bajaj 15L GPU coz of the external adjustable thermostat.

    I look forward hearing from you.


    • Abhishek says:


      I think you have chosen the right model. If you get hard water, it is better to go for plastic body. Plus the external adjustable thermostat is added advantage (as you can adjust the thermostat to a lower setting).


  5. naq says:

    is there ant list for instant water gyesers. which is the best for hard water & low electricity bill. i have bajaj instant gyezer but after 3 years inspite of service the electricity bill has gone up

    • abhishekjain203 says:

      hi naq,

      Can you please check you electricity meter and find out how many units are used per day when you use instant geyzer and when you do not use the same? This can help you find out how much electricity does your water heater take per day.


  6. kumar malothra says:

    hello abhy the shivalik 3 litres instant geyser has a preset temp of 65 degrees so you would not need to change the temperature, most products have an internal thermostat set at 65 degrees

  7. Darsh says:

    Hi, Can you tell me what will be the best water heater if I want to use it with shower?
    What capacity will be ideal for a family of 3 and which company?
    Also, how effective can Solar water heater be? specially in winter when temp drops to 7-8 degrees?

    • abhishekjain203 says:

      Hello Darsh,

      Ideally electricity consumption of water heater is directly dependent on the amount of water you heat. If you buy a water heater with bigger storage, then you might end up heating excess water which will loose heat when left in the heater. Typically a bucket bath consumes about 15 lts (1 bucket) and if you use shower, you may use about 30 lts of water. A water heater heats water to about 60-70 degrees which is quite hot and that’s why you end up mixing cold water in it. If temperature at your place goes down to 7-8 degrees, then may be 25 lts water heater should be good for you.

      As for the solar water heater, it also works with diffused radiation in the atmosphere. As long as it is not overcast for long and there is some sunlight, it works well.

      Hope this helps.


      • Darsh says:

        Thanks for reply. So 15Lits seems good enough…Also I have heard that mixing of water produces changing water temps in a shower. anyone with experience pls share.

  8. Abhy says:

    Kindly provide comparisons on instant water heater models such as racold, kenstar, ao smith etc.

    • abhishekjain203 says:

      Hello Abhy,

      If you look at the star rating of water heaters, you will see that they are rated on “Standing Loss” which is the amount of electricity that water heater looses when water is left standing in it. With instant water heaters, there is no storage, and thus there is no standing loss. For water heaters, the amount of electricity used is directly proportional to amount of water heated, so instant water heaters turn out to be quite efficient in terms of electricity consumption, although having high wattage, they are a big load on the electricity grid.

      We do not have data on instant water heaters because they are not rated on BEE star rating, and it is difficult to do a comparison because there is no standing loss in them. I would suggest that if you are buying an instant water heater, go for the brand of your preference where you have experienced good service in the past.

      Hope this helps.


      • Abhy says:

        Thanks a ton..However it left me in a confused state but still thanks for the good info. According to articles published here I am trying to look for instant geysers of copper tub and element. I had got majority options of Stainless Steel tubs but a minority like Alpar which may have copper tub…I am trying to go with Inalsa Instant Water Geyser which may perform better I hope.

      • Abhy says:

        I concluded with Shivalik 3 Lt instant water heater. Still couldn’t understand the meaning of capacity for instant geysers in liters as they have no storage. It cost me Rs. 2400/- + Rs. 200 installation + Rs. 100/- for pipes + Rs. 30 for three pin plug which was not included in unit which sums to Rs. 2730. Also there was surprisingly no manual inside the box (although warranty card was there). Is there any heat setting in this model if you know please share?

        • abhishekjain203 says:

          Hi Abhy,

          It should have a thermostat to set the heat level. Does it not?


          • Abhy says:

            well the box didn’t contained any manual and till now I hadn’t taken help of some stool to stand up and see the settings :). .Kindly guide if u know exact location of thermostat?

    I have bought a new flat in Bangalore. I am confused in selecting a geyser. I have 2 bathroom. Total members in my flat may be maximum 6(rare) and minimum 4(always). Please tell me how many litre capacity geyser should I buy and which brand to chose.

    • abhishekjain203 says:


      The best use of water heater happens when it is switched on before use and switched off after. And it is always good to buy a water heater as small as possible. Considering that winters in B’lore are cold, a 25 lts water heater should be more than enough if you use good amount of water. If you are conservative in water usage, even a 15 lts one might do. But 25lts one is on a safer side. As far as brand is concerned, any good brand which makes water heaters that comply to Indian Standards (with ISI mark) is good. What is more important is the right usage of water heater (for electricity consumption).

      Hope this helps.

    Can any one give information on Benchmark Geyser??? Abt Service and how it is function wise??

  11. namrata says:

    i hv purchased kenstar geyser and it is the first year and its tank is leaking and no body in this company is bothered to solve my problem even after making several complaints. i can say this that this company has no respect for their consumers . they have employed the worst representatives without manners . i would never ever recommend this product to anyone

    • Bharat Bhalla says:

      Dear Namrata,

      This is very common problem in Kenstar & almost every third consumer of Kenstar is suffering from this, reason being they are using stainless steel tank which is not able to sustain hard water for too long, to avoid this problem of Hard water nowadays all good companies are offering glass lined tanks, please go for any branded Geyser with Glass lining. Kenstar has also recognized this problem & they have also start providing Glass lined water Heaters but they are too costly.

  12. neha goyal says:

    Hi ..can anyone please give their reviews about geysers of Shivalik brand,capacity 15 lts.. ?

    • Bharat Bhalla says:

      Dear Neha, Shivalik is very good brand but condition is you shall be resident of Bangalore since they have their registered dealer in Bangalore only, service is big problem in remaining part of India. However you can go for Bajaj Shakti 5 star range of Geysers, they are glass lined & suitable for high rise buildings, secondly i am using this Geyser & it heats water in hardly 7-8 mins.

  13. Samit Joshi says:

    pls upload for gilma geysers

    • abhishekjain203 says:

      Hello Mr Joshi,

      The above ranking is based on standby power consumption as per Bureau of Energy Efficiency ratings. We do have Gilma Geysers in our database as they are rated by BEE. But they are not the most efficient on BEE star ratings and thus they do not appear on this list.


  14. Mariam says:

    Thanks for the information. I would like to know information for Racold brand? Any specific reason it is not mention in the list?

  15. peeran says:
