Electricity Saving Tips For Homes And Offices

Top Ten Water Heaters/geysers in India by standing loss and size in 2017

By on May 6, 2017

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:

  • 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.
  • We regularly update this list as new models get added in the BEE list of water heaters.

Hi Team,
You can listed Reconnect in the 15 litres category. Is it really good since this is the first time I am hearing about a reconnect product being good.

Abhishek Jain (Mod)

Hi,

Our table is directly based on data from Bureau or Energy Efficiency and the only parameter being used is standing loss. We do not apply any brand perception in preparing the lists.

Abhishek Jain (Mod)

Hi Rakesh,

I just checked your messages and somehow they were lying the spam section of comments. Not sure why. I typically check the moderation queue, but not the spam one. Usually one goes in SPAM due to certain IP address ranges, email addresses, etc. I guess in your case it was IP address, but I am not sure.

Well for instant water heaters, manufacturers publish very limited data and unfortunately there are no standards for manufacturers to publish data. So the decision has to be made based on the limited data that we have.

Among the brands you have listed, I would say Havells and AO Smith are really good brands. Havells model has ABS outer body, SS 304 inner tank and copper heating element. But if you get hard water, then there is no corrosion protection for the heating element. Although SS 304 tank should be able to stand hard water. But heating element is doubtful.

AO Smith model again has ABS body, but there is no mention of material for inner tank (however, their website says 7 year warranty on inner tank with 5 year replacement warranty, so I guess the material would be good), the heating element has glass coating for corrosion protection.

Bajaj does not provide much information on material and just says long life heating element or warranty on tank. Crompton also does not provide information on heating element.

So I guess the best choice is AO Smith EWS in this case.

Hi Rakesh,

Currently we do not have much data to select the right Instant Geyser. You may go for one from top brands like Havells or AO Smith.

5
Abhishek Jain (Mod)

Hi Rakesh,

It is not that Instant Geysers are not energy efficient. In fact if you are able to manage with it, then it can be the most energy efficient. The smallest you can buy for your needs the better it is from electricity saving point of view. The only challenge with instant is that instant electric geysers are not able to give proper output. Because the storage is less, you soon run out of hot water. And that is why it is good enough for small use like kitchen. For bathroom gas instant geysers are better. You can check more over here: https://www.bijlibachao.com/water-heaters/instant-water-heater-geyser-may-be-good-for-individual-but-bad-for-system.html

As for the two models, you should certainly go with Adonia Digital as it gives better warranty. ELCB (shock resistance) is there in Quatro as well.

6

Hi Abhishek, Thank you for constantly updating the website and providing useful information. I am going for Digital variants of 15 Ltrs of Water Geysers , will it be good,your opinions about digital variants ? If Digital is good then I want to buy between AO Smith's HSE SES & HSE SFS AND Havell's Quatro Digital & Adonia Digital. if you have any other model no. of any other brand or so then you can suggest me. As this is the first time i'm buying a Geyser so I want a good one for my home.So help Me selecting.

Abhishek Jain (Mod)

Hi Rakesh,

Digital variants give convenience of operating the water heater. They have lot of features where you can use timers etc to make sure that your geyser starts on a particular time and switches off on a fixed time. You can also use a remote control to vary the hot water temperature. Plus a lot of other features.

If you use it, then it certainly has benefits as in you need not remember to switch it off and it will switch off automatically. There is no way it will run through out the day as it will switch off automatically. The models from Havells also have added features that stop mixing of hot and cold water in the geyser thus giving you consistent hot water.

If you do not use the features then it will be as good as any other geyser. But there are advantages of using these features as it gives convenience and also saves electricity. So certainly they are better.

Also I personally find Havells models having very good features that can be very useful. So I think Havells Quatro Digital can be a good buy.

We have a solar connection but during winters it is inefficient. So we are planning to add geyser in our bathroom. We have got two bathrooms so please guide us which one will be the best and which has geyser detects the temperature beforehand so that it heats accordingly during winters and summers.

9
Abhishek Jain (Mod)

All geysers have a thermostat which makes sure that the temperature of water in it is not more than a set temperature. So you can put any geyser in the bathroom, just make sure that the input to the electric geyser comes from output of solar geyser. If the water is hot enough, your electric geyser will not even try to heat it and thus the solution will work perfectly for you both in winters and summers.

Hi Sir,
I would like to install a 25lts based on the below details
1. Energy Efficient
2. Hard water to soft water converter
3 Best in service.
Kindly request your advise,
Thank you,
Waiting for your reply

11

You can use a separate water filter container with antiscalant balls available amazon to make hard water soft before geyser connection. I don't know if it works but this can be home remedy for such things. Always ask experts before doing it.

12
Abhishek Jain (Mod)

Hi Nirmal,

We do not have information on models with water softner. So I am sorry, I would not be able to help you on this.

Hi Mr.Jain,

I live in Chennai. Using a 25 L bajaj geyser. Hard water. Nowadays I find it is taking a lot of time for the water to get heated. Do I need to change heating element ? Pls adivse. Thanks..

19
Abhishek Jain (Mod)

It could be possible that there is deposition on the heating element. You should get it checked.

20

Thanks. Mr. Jain. Heating element is more than 3 years old. Should I change it ? Also how to clean deposits on the element.

21
Abhishek Jain (Mod)

You will need to take it out and check it. Even after cleaning it will still need corrosion protection, so you will have to apply something for that. If it is not in good shape then you will need to replace it. See if your electrician can help you out.

22

Mr.Jain, I got the heating element replaced. The problem presists, takes even longer for water to heat up,

23
Abhishek Jain (Mod)

The time for heating depends a lot on the wattage of heating element and of course there should be no corrosion of the heating element. Is the wattage of heating element the same as what it was earlier?

24

Hi Abhishek,

Thanks for providing such detailed info on water storage heaters.

I am doing up my place in Navi Mumbai.

I need to buy three 50l storage heaters + two 35l storage heaters.
I want to have temperature control on the heaters. Does not need to be smart phone compliant; corded remote is sufficient for me in all bathrooms.
I checked out the AO CEWHR which seems like a decent product.
Would you recommend this product or are there better ones available that suit my requirements.

Thanks once again.,

25
Abhishek Jain (Mod)

Hello Mr Aziz,

I am sorry we do not capture the information that you are looking for. The objective here is to help people make an informed decision as far as electricity consumption is concerned. So we collect information from Bureau of Energy Efficiency (models, their star rating and energy efficiency). After that we just check if the models are available in the market or not, their prices, etc. We do not capture features and orientation of models. So I will not be able to provide you most efficient models that are horizontal.

26

Sorry forgot to provide more info:

Heater needs to be horizontal; wall mounted on the ceiling.

Thanks :)

27

Dear Abhishek and Bijli Bachao Team,
Thanks for a very well written article and the rankings. It helped a lot in deciding to go for the right geyser.

Abhishek, after discussing with you I finally opted to buy the Venus 50 Lts for the Mother Teresa Home for Destitute as it has a good warrenty period.
Thanks for all the help.
Regards,
Amit

Hey Amit,

I am happy that the information was of help :)

Hello Abhishek,

Prakash here. We are family of three (me, wife and 2 year old son). We live in an apartment in Bengaluru and we do have both corporation water as well as bore water. I need you advise on buying two geysers - one for common bathroom and the other was master bedroom. Generally, not many guests will stay in our house and even if they stay not more than three members will stay with us.

Now, I need your advise on which brands to select for my requirements and considering our bore water in Bengaluru. How many liters should we opt for two bathrooms? Generally, we do take bucket baths.

30
Abhishek Jain (Mod)

Hi Prakash,

10 lts is good for bucket bath and 15 lts is good enough for shower bath. You can look at the top ten list above for models. In general Havells, AO Smith, Bajaj, Venus, Racold, Morphy Richards, Ferolli are good brands.

31
Abhishek Jain (Mod)

Just look for a brand that gives maximum warranty. My guess is that you will get max warranty in Venus.

32

Thank you for your respone

Anything Wrong About American Micronic 25l ??? Good and positive reviews except few who said it takes 25-30 mins. For heating help asap i want to order a geysar today only on amazon.

34
Abhishek Jain (Mod)

Hi Amit,

We have no idea about American Micronic as it is not listed on BEE and I am hearing about this brand for the first time.

35

Hello ,
I want to buy A Geysar for family of four please suggest me a specific one? Rather than suggesting many?

36

Hello,
I want to buy a geyser of 25ltr, I am confused between Venus (Lyra), Racold (Eterno 2) and V guard (Pebble Metallica).
Which among these would be long lasting and energy efficient. Please advise me the best within there 3 geysers.

37
Abhishek Jain (Mod)

Hi Jeetu,

Racold has not published its energy efficiency data properly and thus I cannot comment on it. But VGuard Pebble Metallica looks really good with good energy efficiency as well as awesome warranty of 3 yrs on product, 4 years on heating element and 10 years on tank. This is the best warranty that you can get from any brand. I think VGuard model is the best choice.

38

Thank you.
But you didnt talk about Venus Lyra. Hope you noticed it. Would it be a smart choice to select a geyser by simply looking at warranty conditions.
Please suggest the best in all aspects like features, technology and can be trusted in long term.

39
Abhishek Jain (Mod)

Hi Jeetu,

I did notice Venus Lyra and I responded based on the parameters that you were looking for: Long Lasting and Energy Efficiency.

As far as technology is concerned it truly depends on what you need and what you want. There are SMART water heaters available that you can control through your remote, smart phone, etc. They have features like no mixing of hot and cold water, earth leakage circuit breaker to prevent electric shocks, timers to on and off the geyser, etc. You will find that Havells has some digital models that are most feature rich.

The models you had listed were similar and had all standard features. And these days most top brand have good corrosion protection for tanks and heating element that are important for durability. And that is where a brand that is confident to give long warranty on these gives more confidence.

40

Thank you very much for the valuable information. Leaving all the discussion behind, which brand and/or specific model of geyser would you recommend in 25ltr and 15ltr segment, that can be trusted universally.

41
Abhishek Jain (Mod)

Hi Jeetu,

I cannot recommend a specific brand as every brand has its pros and cons. There is no universal brand that fits in every requirement. You can look at the list of top models in the list above and choose as per your brand preference.

42

Hi sir,
I live in a rural area with 6 family members. The geyser will be installed for 2 bathrooms simultaneously, and all family members will be using it for shower as well as bucket baths(2-3 person). I have a list of queries in my mind:-
1. What should be the capacity of my geyser, my plumber suggested me a 25ltr.
2. Is there any geyser which comes with copper tank and copper heating element.
3. Which tank is best against hard water corrosion and able to withstand high pressure.
4. Which is the. most energy efficient and has least standing loss, heats water quickly.
Please suggest me the best geyser that is energy efficient, durable long lasting and has good safety features in terms of tank bursting and minimum standing loss. I checked your list but couldn't decide, please give a specific model.
Thanks.

43
Abhishek Jain (Mod)

HI Aman,

Here is my response:

1) Ideally I suggest going for smaller individual water heaters for each bathroom (10 lts for bucket bath and 15 lts for shower bath). But if you are going for one single common then 25 lts should be good enough.

2) Even copper can corrode so just looking for copper is not good enough. There are far better technologies for corrosion protection in the market. We have written about them on this link: https://www.bijlibachao.com/water-heaters/coating-storage-water-heater-thermoplastic-stainless-steel-enamel-coating-glasslined.html

3) Most top brands have good corrosion protection and can handle high pressure. Havells, Bajaj, AO Smith, Racold, Venus, Morphy Richards, Ferolli all are good brands. Most of their products can handle high pressure and have good corrosion protection. You should look for one that is giving good warranty on tank as well as heating element. Also although most of their products can handle high pressure but the total pressure it can handle is mostly mentioned in the specifications.

4) The data is there in the list above. We just provide information to people so that they can make an informed decision, it is difficult for us to go much beyond that.

44

Thanks for your valuable advice. I understood it is better to go for a better tank option than copper. But my local dealer told to go with a copper coiled heating element that is better in terms of efficiency. He was talking about some V-guard models. Is it true, do any brand have copper coiled heating elements?

As you said above about Racold, I checked the list but there is not any geyser of racold in 25ltr section. Please provide a updated comparison list link.
Thanks.

45
Abhishek Jain (Mod)

VGuard is also a good brand. You can go for VGuard as well. The reason Racold does not appear in the list above is because our list is prepared based on data from Bureau of Energy Efficiency. We take BEE's list and then compare it with models that are listed on a manufacturers' websites. We do this because BEE's list has lot of models that manufacturers are not selling (they just get them registered). Now with Racold we are not able to find the matching models that they have registered with BEE on their website. The naming convention that they use to register with BEE does not match with what they sell and it is difficult to find the right match. And thus they do not appear on this list.

46

Racold has multiple models being manufactured but those are registered in BEE as a model family. Racold has models of Pronto, CDR, Altro, Eterno, Andris, Platinum etc. and each of them having capacities in different range (6 Ltr to 300 Ltrs). Racold's most of the vertical models (below 50 Ltr) are 5 Star rated where as all the horizontal products (up to 50 Ltr) are either 4 star or 3 star rated based on capacities. Racold water heater's SPHP coating on tank is the best coating in the present water heaters across India.

47
Abhishek Jain (Mod)

I guess you work with Racold and it is great that you have commented
here. I am attaching a screenshot of data from BEE website. Please help
me understand how can these models be linked to models that exist on
Racold website. It is extremely confusing and frustrating for a consumer to figure out which models are star rated.

48

Can I take Racold eterno 2 25 L water heater. Please suggest me.
Thanks

49
Abhishek Jain (Mod)

You can surely go for it. It is a good brand.

50

Hi Abhishek, i live in chennai. i am the only person who would be using geyser on daily basis. what geyser would you recommend for bucket bath and shower? Help is appreciated!!!

51
Abhishek Jain (Mod)

You can look at the list of top 10 lts models in the table above. 10 lts should be good for you.

52

Thx for the response, if its not too much trouble i would like to know which one you would pick..............Thank you for your efforts and this dedicated site.

53
Abhishek Jain (Mod)

Hi Irshad,

All I would say that Havells, Racold, AO Smith, Bajaj, Morphy Richards, Venus, Ferolli are some good brands. You can go for any one of them in the top list.

54

Hello Abhishek,

I live in Kolkata. In my area, water contain irons and it damage the geyser in some times. I checked with electrician and he suggested to go for Venus brand only. I m looking a geyser with 15 ltrs capacity. Could you please suggest me the the best model which is best to use with hard water? I will use the geyser everyday for 30 mins and rest of other time it will kept switched off.

Thanks in advance.

55
Abhishek Jain (Mod)

Venus is a good brand and you can certainly go for it. Here are some models from Venus that are energy efficient:

15GL
15R
15EV
15VL
15RX
15RD

These days most geysers come with good corrosion protection for tank and the heating element. Top brands like Havells, AO Smith, Racold, Bajaj, etc give 7 years warranty on the tank and 4 years on heating element. Just go for a brand that gives good warranty on tank and heating element. Venus is also good.

56

Reconnect geysers by reliance digital... R they good?? Please reply me ...

57
Abhishek Jain (Mod)

As you have asked about a specific brand, then I will just copy and paste a reply that I have given to someone else in the past:

Since there is a huge demand for cheap products in India, there are many companies that are importing cheaply manufactured products from China and putting their own brand name on them and selling it in Indian market. They are not the OEM (or Original Equipment Manufacturers). Most electronic retail stores have such brands like Future Group has Koryo, Reliance has Reconnect, Vijay Sales has Vise, Croma has Croma. These guys are not OEMs but they are just importing from china and putting their name (brand). If you want to buy them, you can buy them at your own risk.

58

Hi Abhishek- Is havells adonia geyser good? how does it compare with AO Smith SBS digital??

59
Abhishek Jain (Mod)

Although AO Smith SBS Digital has slightly lesser standing losses but the safety features in Havells Adonia are quite good and in general it is better from a technology perspective. I think you should go for Havells Adonia. Warranties are same on both.

60

Hi Abhishek - had posted a query 4 days back but do not see the answer . I am installing rain shower in my bathrooms . I was told we need to use 40 litre storage water heater . But my contractor says 25 litre would suffice . Please guide what is correct and what model do you recommend in horizontal storage water heaters . For further info , i am on 2nd floor and my building is 12 storey tall . Thanks in advance . Pravin Tonsekar

61
Abhishek Jain (Mod)

Ideally I tell people to install a 10 lts model if people in the house use bucket bath and 15 lts in case of shower bath. Both 25 lts and 40 lts are much bigger. The electricity consumption depends on volume of water you heat and with bigger water heaters its highly likely that you heat excess water.

62

Thanks abhishek . Would 15 litres suffice for rain shower ? for a 25 litre which brand do you suggest for horizontal placement .

63
Abhishek Jain (Mod)

I am not sure. If it needs more water then you will have to go for 25 lts. The list of top most efficient models are listed in the table on this page. You can refer to the same for models.

64

Thanks Abhishek

65

Dear Abhishek,
Hi
What are the standing loss of Bajaj Majestic GPU 25 litres & Havells Puro Plus 25 litres to decide my preference.
For a family of two person & three bathrooms once in a while 2-3 guests coming for 1-2 nights, should all bathrooms have separate 25 litres Geysers in Jaipur Rajasthan or smaller size can be OK? Bajaj is cost effective by 20-25 % comparing to Havells but Bajaj & Racold are of similar rates for me. In which brand I should invest to avoid future headache ?

66
Abhishek Jain (Mod)

Bajaj Majesty 25 GPU has standing loss of 0.602 and Havells Puro Plus 25 has standing loss of 0.56 .... so Havells Puro Plus is more energy efficient. Bajaj CALDIA 25L or CALENTA 25 would be equivalent to Havells Puro Plus.

67

Hi Abhishek,

I've 2 very simple queries..
#1) For a Family of 5 persons what will be the ideal size (ltr) of a Geyser?
#2) Longevity and reliability wise which Brand will you suggest as the Best?

Regards,
Rajarshi

68
Abhishek Jain (Mod)

Here is my response:

1) If it is not too cold in winters then 6 lts is good for bucket bath and 10 lts for shower bath. If it is cold then 10 lts for bucket bath and 15 lts for shower bath is good. This is irrespective of number of people in the house.

2) Try to go for a brand where you get maximum warranty on tank as well as heating element. In general Havells, Bajaj, AO Smith, Racold, Morphy Richards, Ferolli are good brands.

69

Sir, i am in hyderabad, I want to buy geysers for my 3 bed apartment. Please suggest me the combination of geysers - like one 15 ltr, and two 6 lt. etc. to save on the purchase cost. saving on recurring energy bill also is a concern.thank you.

70
Abhishek Jain (Mod)

Hello Mr Srivathsa,

If it is not too cold in winters then 6 lts is good for bucket bath and 10 lts for shower bath. If it is cold then 10 lts for bucket bath and 15 lts for shower bath is good. You can look at the list of top most efficient heaters in the table above. Havells, Bajaj, AO Smith, Racold, Morphy Richards, Ferolli are some good brands.

71

Hi, which water heater is good * AO Smith HSE-SDS-15 15-Litre 2000-Watt Vertical Water Heater or * AO Smith HSE-VAS 15-Litre 2000-Watt Storage Water Heater (White), interms of material and energy.

72
Abhishek Jain (Mod)

Both the water heaters have same specifications and features. The only difference is in the design (look and feel). You can go for any one of them that fits your requirements.

74

Hi...Consider a use case where the water heater is used by correctly switching on and off exactly before and after use regularly. In this case I assume standing loss is not a parameter for calculating energy efficiency. Is my understanding right? If yes, how will the top 10 list change? (as I see that you've used standing loss as the primary parameter for ranking)

75
Abhishek Jain (Mod)

Hi Karthik,

If you use it properly as you mentioned, then standing loss will not be a big impact. It will be quite small. And in that case you can choose any model from a good brand. It will be difficult to put a top 10 list in that case because then it will become a subjective list (based on my perception of various brands). Here the models are being compared on hard data.

76

Thanks for the quick response Abhishek!

81

Hello, I was looking for a 25 ltr storage geyser and came across the geyser from reliance reconnect...but it seems to be an instant geyser... Can u plz advice me on the same and also help me find out if they have a storage one too? Also hw would the instant 25 ltr geyser work? Thanks in advance...

82
Abhishek Jain (Mod)

Hello,

Firstly I would say 25 its geyser is not an instant geyser because by definition an instant geyser should store very less water (1 lt or 3 lt). So 25 lt cannot be called an instant and should be called storage geyser. It may have a high wattage heating element, but instant should be one which should heat water as it comes in and should not store anything (or store very less).

Now as far as reconnect as a brand is concerned, let me copy a text that I use to reply to people asking about certain brands:

Since there is a huge demand for cheap products in India, there are many companies that are importing cheaply manufactured products from China and putting their own brand name on them and selling it in Indian market. They are not the OEM (or Original Equipment Manufacturers). Most electronic retail stores have such brands like Future Group has Koryo, Reliance has Reconnect, Vijay Sales has Vise, Croma has Croma. These guys are not OEMs but they are just importing from china and putting their name (brand). If you want to buy them, you can buy them at your own risk.

83

Yeah....I thought so as by the definition.. 25 ltr has to be a storage geyser else what's the point...also I get ur point too and agree that reconnect geyser is a cheaper option ...thanku though...its better not to buy it..here is a link to the product in case u wish to see :) http://www.amazon.in/gp/aw/d/B01AAETLOG/ref=pd_aw_sim_sbs_60_of_1?ie=UTF8&psc=1&refRID=0F15K629ZTVNCT3EYJSX .
Also kudos to u for giving such a detailed info on the blog...I never thought there could be anyone writing about geysers and promptly replying to everyone's queries..good job...

Is a 6 lt water heater enough for bucket bath of 1 person in Kolkata city ?

85
Abhishek Jain (Mod)

should be good enough.

86

Hi Abhisek,
I am looking to buy a water geyser for 1 person will the 10 liter geyser be enough for shower use ?
One of the salesman told me that 10 liters is an odd amount of storage is it true ?
Please could you recommend the top 3 models as I was considering to but racold, havells or Ao smith. Please suggest the best available product in terms of durability and usage.

87
Abhishek Jain (Mod)

Hi,

Depends on where you live and the climate over there. It may turn out a bit small if you live in Delhi or north India. It would be sufficient for shower bath if you live in Mumbai. A 15 its model would be perfectly safe in most parts of the country. You can look at the list given above to check the top models.

88

Hi abhishek,
Thank you for your reply, I live in bangalore. The usage of the shower is for a daily purpose.is 10 liter ideal or do I need to buy the 15 liter one. Please suggest the top 3 models of your choice considering durability, good service and value for money.

90
Abhishek Jain (Mod)

Bangalore is a bit cold in winters. So 15 lts would be better for shower. Havells, Racold, AO Smith, Bajaj, Morphy Richards, Venus are some top brands. You can check the list of top 10 15 lts models in the table above on this page.

91

Thanks Abhishek, can you suggest me any 2 models that I can go for ?

92
Abhishek Jain (Mod)

Hello Mr Ahmed,

I have given you names of some of the top brands. I would suggest that you look at the list of top most efficient water heaters in the tables above (of the brands that I have give) and choose between them.

93

Hi Abhishek,
I am thinking of buying Racold Eterno 2 10litre storage geysar. Is it a good model?? Is there any negative points/disadvantages of this model??
Is it better than Havells Monza-ec model??
Please suggest.

94
Abhishek Jain (Mod)

Energy Efficiency wise both are similar. Even the specs are quite similar (both hand handle high pressure, have good insulation and corrosion protection, similar heating element). But there is more warranty on Racold, so I would suggest that you go for Racold Eterno 2.

95

Thanks Abhishek. Is there any other brands better than Racold in this price range??

96
Abhishek Jain (Mod)

Racold, AO Smith, Havells, Bajaj, Morphy Richards, Venus etc are some of the good water heater brands.

97

Hi Abhishek,

Can you suggest which one of these four models is the best one to buy.
1. Media Mwhsa0255Vk (25 Ltrs)
2. HSE-SAS (25 ltrs)
3. HSE-VAS (25 ltrs)
4. Havells quatro 25 L white-grey GHWEQTTWH025

Please explain some Pros & cons as well for each of them while responding back. I am getting all these at almost same price range.

I need the best option so please suggest.

Thanks

98
Abhishek Jain (Mod)

Hi Yogesh,

AO Smith, Havells both are top brands. They have the most efficient models and they have good insulation and durability. AO Smith is an American brand and Havells is an Indian brand. I personally have a lot of liking for Havells (it is one Indian brand that makes very good products). Havells also has some digital water heaters that have really advanced features for temperature management, remote control, etc. Havells Quatro Digital is a great model. But the model you have chosen is the non digital one.

Now AO Smith HSE VAS is the most energy efficient model. But the difference between efficiency is minimal. All the models you have listed have good corrosion protection for tank and heating element. They also have good insulation (that is why they are energy efficient). But I think the deal breaker for me is the presence of ELCB (Earth Leakage Circuit Breaker) to prevent electric shocks and Whirl Flow Technology (to prevent mixing of cold and hot water in water heater to ensure energy efficiency) in Havells Quatro. I think Havells Quatro has better technology and is a better model.

99

Hi Abhishek,
I was going to recommend my parents a 3 litres instant geyser, but after going through your discussion, I am confused!!!
Of course, electricity saving, safety, corrosion protection, auto - cut and water speed are the most important features for the geyser...but I am not sure whether an instant geyser would be perfect for them or they should buy a 6 or 10 litres geyser. They will use bucket and may connect it to the washbasin. Also, which brand and model would you suggest. Thank U in advance!

100
Abhishek Jain (Mod)

Hi Mauli,

It depends on where they are located. If they are in North (Delhi and adjoining states) then it is better to go for a 10 lts geyser. If you are slightly south where the temperature is generally warm, then 6 lts is also fine. I personally have one 6 lts in Mumbai and it works fine for bucket bath (not so much for shower bath). But Mumbai in general does not get too cold.

101

Thank you! Would you please suggest a good model for 10 litre geyser...

102
Abhishek Jain (Mod)

You can look at any of these:

Morphy Richards Lavo Em10
Ao Smith Hse-Sbs-010
Ao Smith Hse-Sas-010
Ao Smith Hse-Sfs-010
Morphy Richards Salvo 10L
Havells Quatro 10
Havells Monza Ec 10
Havells Opal 10
Havells Puro Plus 10
Bajaj Bajaj Majesty 10 L Horz
Bajaj Shakti Gpv 10 Gl
Bajaj Caldia 10L
Bajaj Calenta 10

103

Sir,I require a water heater/ geyser for my home. 4 members in the family. Single floor usage for bathroom, kitchen and wash Basin connected through single water pipeline. Bath preferred with bucket. Please suggest some options. Which would be better - instant or storage type- considering my usage?

104
Abhishek Jain (Mod)

If you use hot water for so many things then you should go for a bigger geyser (say 25 lts). Instant geyser will not work in your situation. It would have worked if you needed it just for kitchen or just for wash basin. You can check the list of top 25 lts model in the list above.

105

Thanks for ur reply sir. I will not be using all the outlets at the same time. Moreover, my primary requirement is for bathing. I am not able to understand the working of an instant water heater. Can I consider a 6 ltr instant Heater? 25 ltr storage type requires quite some place, which can be a problem for me.

106
Abhishek Jain (Mod)

6 lts is not technically classified as instant geyser as it does not have higher kW heating element. Instant geysers have high kW heating elements (mostly 3-4 KW) to heat faster. Now a lot depends on the temperature of water in your city and amount of water you need for bathing. I personally have a 6 lts in one of my bathrooms. It is great for bucket bath but not sufficient for a comfortable shower bath. And this is in Mumbai where water is not too cold in general.

107

Sir how does the capacity of a 1 ltr and 3 ltr instant geyser make a difference. Does 3 ltr mean rate of heat conversion capacity. Can u explain me? I m living in Delhi. My concern is that my bathroom is small and a 25 ltr storage tank will create a problem. I am confused whether I should go for a instant geyser or storage type. I actually am inclined towards instant but not sure if it will serve the purpose.

108
Abhishek Jain (Mod)

A 1 lts water heater can store 1 lts water and a 3 lts water heater can store 3 lts water. When you start the heater, depending on its heating element power, it will heat 1 lts or 3 lts water depending on the size. Typically, these small water heaters have 3-4 kW heating element which heats this water 1 or 3 lts fast. The challenge happens once you finish this 1 or 3 lts water as the geyser starts filling up the heater again with cold water.

Now when you started the geyser you gave 2-3 mins for original 1 or 3 lts to heat up. But the new cold water that comes in does not get that much time to heat up because your tap is open and the water is flowing through. So after you take the first 1 lts which is hot, the next 1 lts will not get 2-3 mins inside the geyser to heat up to the same level. And if the climate is too cold (as in Delhi) it will need much more time. So when you open the tap initially, you will get hot water, but that flow of hot water will be there only for first few mins (or seconds depending on the flow rate at which you open the tap). But then it will not be as hot as it started with.

Typically in Delhi, 10 lts water heater is good for bucket bath and 15 lts for shower bath.

109

Sir, thanks a lot for clearing my doubt.

110

We are of three member family (wife, husband and a kid) living in 2BHK flat in Hyderabad. We have common gyeser connection for two bathrooms. Please suggest appropriate size, brand and model?

111
Abhishek Jain (Mod)

Go for 15 lts model if one bathroom is rarely used (or if both bathrooms will not be used together). If the two bathrooms will be used together then 25 lts one would be good enough. You can check the models in the top ten list mentioned above.

112

Thank you Abhishek!

113

We live in Tiruchirapalli. we need hot water only from November to February. What brand and model would you Suggest? There are four members in our family

114
Abhishek Jain (Mod)

The size of water heater will depend on the volume of water you use. If you prefer bucket bath then 10 lts and if shower then 15 lts. Top models of both these sizes are mentioned on the table on this page.

115

Thank you very much. I bought Havells Puroplus 10 l .

116

how is the performance of Havells Puroplus 10 Ltr.

117

Which geyser is good to use (Electric or Gas) including low costing, and whats your recommendation (Brand wise) also those have Temp Control knob.

Thank you.
Regards Kamal Singh

119

What things should keep in mind before u purchage water heater?

120
Abhishek Jain (Mod)

Try to go for one with lowest standing loss. It will be better if you have a temperature control knob as you can reduce the heating to reduce your electricity consumption. Make sure that the water heater body and heating element have corrosion protection.

121

If I cover entire geyser (pipes as well) with insulator foam OR place it in a box (suppose like in its packing box), OR hide geyser above false ceiling(my bathroom has false ceiling), will it be beneficial to save heatelectricity?

122
Abhishek Jain (Mod)

It should certainly help to save electricity.

123

Hi Abhishek, You replied all my quires, .. warm regards to you.
Thanks for your expert advises.

124

Hi Abhishek. I have another question. We are four (2 adults and 2 children). How many liters of water heater is enough for us. Generally we do bucket bath only. If we use shower bath also the same capacity is enough for four persons or we should go for 15 liters?

125
Abhishek Jain (Mod)

Generally 10 lts water heater is good for bucket bath. For shower bath, 15 lts should be good enough. Same capacity is good enough for 4 persons because water will get heated by the time next person uses it.

126

Hi.. Abhishek

Can you advice me which is the best water geyser between Midea MWHSA0155VK and AO Smith HSE-SBS 15 ltr.

127
Abhishek Jain (Mod)

I think AO Smith model would be better.

128

And in AO smith, Morphy Richards and Midea (25 L)??

129
Abhishek Jain (Mod)

Media Mwhsa0255Vk is the most energy efficient 25 lts model. Followed by Morphy Richards Lavo Em25 or Lavo Digi25. AO Smith models like Hse-Vas-025, Hse-Sas-025 are also quite energy efficient.

130

Hi,

We are a family of 4 and want to buy a 25 Ltr Water Heater (vertical model). We stay in Bangalore. Kindly suggest a suitable water heater. We are confused with the different brands & models. Kindly provide your valuable advise.

131
Abhishek Jain (Mod)

You can look at these:

Morphy Richards Lavo Em25 or Lavo Digi25
A O Smith Hse-Vas-025
Ferolli Caldo.25Vmp
Havells Monza Ec 25

132

Thanks for ur reply Mr.Abhishek, any advice on Racold models

133
Abhishek Jain (Mod)

Racold Eswh-25V and Racold Eswh(Dg/Sw)-25V would be the most energy efficient models from Racold.

134

If I will use 610 ltr storage water heater for kitchen in 2 member family then it will be good??

135
Abhishek Jain (Mod)

Instant water heater of 3 lts should be good enough for kitchen. 10 lts is huge.

136

Hi,

We are 6 family members how much liter is enough for us. between 2 people bath 5 min. gap also which brand is best. please reply me soon.

137
Abhishek Jain (Mod)

Lot depends on the city you are in as well. If it is quite cold in winters (like in Delhi) .... you should go for 25 lts (as the gap between two use is quite small) ..... if in Mumbai ... even a 15 lts would work fine. You can look at AO Smith, Racold, Havells, Bajaj, Ferolli, etc.

138

Thanks, which brand is best to buy. we living in delhi.

139
Abhishek Jain (Mod)

Already mentioned a few brands in my previous reply.

140

Sir I m thinking to buy a water geyser of 15 lt..I m confused between ao smith model Hse sas 15lt (Rs. 9500 through reliance digital store) or model Hse vas 15lt (Rs. 6500- 7500 online)
Sir which one is better or should I think about some other brand or model.
Our priority is power saving and less /no maintenance..plz suggests as soon as possible. we belive in"buy one time but buy a very good product" so money is not the matter here. 10k is our budget which is very good for this capacity.

Energy efficiency wise both are similar. HSE-SAS-015 has better material for inner tank which will protect it from corrosion for long. So you can go for HSE-SAS-015.

There are no instant geysers of 10 lts. Instant are only those that are 1 or 3 lts. And you can get the list of top most efficient models in the list given above on this page.

but 1 and 3L is not on the list...

The list above does not contain instant geysers as they are not rated by BEE yet. We only have BEE rated models on this list.

If it will be used for bucket bath, put a 10 lts water heater. If for shower, then go for 15 lts. AO Smith, Racold, Havells, Bajaj, Ferolli are some good brands. You can look at the list above to choose the models.

Hi Vijay,

I am sorry, we do not have any information on that.

Hi,

I had a question about whether we can leave the geyser on when not in use? I have a Havells Puro Plus 25l geyser. Normally we switch the geyser on and forget to switch it off after using it. It remains switched on during the whole day while we are in office. I wanted to know if the geysers are designed to handle this or if i am making a big mistake and causing damage to my geyser. Also even if there is no damage, does it consume a lot of electricity if left on?

It will not damage the geyser, but then it will increase your electricity consumption which is equivalent to the standing loss of the water heater.

There is a thermostat in the geyser which will switch it off when the temperature has reached as per the settings, but when the geyser is switched off, it will loose heat from its surface (which is standing loss). This loss will result in a decrease of temperature of water and the geyser will start again. This will continue till the geyser is switched on. So on a daily basis you will loose the amount of electricity equivalent to standing loss.
