Electricity Saving Tips For Homes And Offices

Super Efficient Fans in India – a result of SEEP (Super Efficient Equipment Programme)

By on September 3, 2017

BEE launched its standards and labeling program in 2006 and since then many electrical appliances are being rated on their efficiency on a scale of 1-5. Most appliances are labeled and sold as BEE star rated appliances. Even after all these years, the level of efficiency of appliances in India has not reached the level of efficiency prevalent in most efficient appliances globally. A study by Prayas group of Pune suggests that if a rapid market transformation is done to only four appliances: room air conditioners, refrigerators, television sets, and ceiling fans: India has potential to save 60 million units of electricity (source). This translates to avoiding a peak capacity addition of 20,000 MW. In view of this BEE has launched a new program to support manufacturing of Super Efficient Appliances and the program has started with Fans.

What are super efficient fans?

A regular ceiling fan that does not include any efficient technology consumes 75-80 Watts of power. Since BEE introduced star rating for ceiling fans, we have started getting fans that are efficient to the point that they consume only 45-50 Watts of power. However some people had complaints with BEE 5 star rated fans about their air delivery being less (and some more, which we discussed in our previous post: BEE 5 Star rated ceiling fans: myths and realities). The regular fans have air delivery of about 250 cumm and BEE 5 star rated fans have air delivery of 210-225 cumm. Looking at all this BEE has proposed a Super Efficient Fan program where fans manufactured will consume only 30-35 Watts of power and would deliver about 230 cumm of air. In the previous post mentioned above, we have already written about our test results of a ceiling fan that delivers about 225 cumm of air and we hardly felt much difference as compared to regular fans. And thus we believe that 230 cumm is a good value.

Comparing Numbers for various kinds of fans

Looking at the high costs for buying a super efficient fan, most people would be interested in comparing numbers before making a buying decision. Below table compares all kinds of fans.

Regular Fan

BEE 5 star Rated Fan

Super Efficient Fan

Wattage

75

50

35

Yearly Units Consumption (assuming 8 hrs usage everyday)

219

146

102

Yearly Electricity Cost (at Rs 5 per unit)

Rs 1095

Rs 730

Rs 511

Cost of Buying

Rs 1200

Rs 1600

Rs 3000

Based on above numbers a BEE 5 star rated fan pays back for additional cost as compared to regular fan within one year.

A Super efficient fan will pay back for itself in about three and half years as compared to a regular fan.

These numbers can vary depending on your use and cost of electricity, which you can validate, using our calculator: Online Electricity Bill Calculator – For all states in India. If your using cost is more than 5 then the payback can be faster. If it is less then it will be slower.

What does Super Efficient Fan technology include?

There are 3 things that are done to improve the efficiency of fans in super efficient fans:

  1. Performance is improved by improving the induction motor.
  2. Use of BLDC (or Brushless DC technology). To know more about brushless DC technology check: http://en.wikipedia.org/wiki/Brushless_DC_electric_motor
  3. Improving the design of the blades.

The above implementations involve replacing some electrical components with electronic components thus allowing for a smoother control of the fans.

As per BEE specifications, these changes should allow super efficient fans to give:

  1. Higher air flow at full speed
  2. Low noise through the use of better quality blades;
  3. In order to be more suitable for Indian conditions:
    1. a.None or very low degradation in performance at lower voltages;
    2. b.Reliable even under high ambient temperature;
  4. Lowest power consumption reasonably possible.

The one downside of a super efficient fan is that the power factor of such fans is 0.9 as compared to 0.95 of regular fans with induction motors. It may impact commercial connections with demand charges in their tariff plan.

Myths about AC stabilizers.
People generally think that their stabilizer will reduce output voltage when Supply Voltage is high and increase output voltage when supply voltage is low. It is not true for all stabilizers. I tested VG 400 Stabilizer for ACs from V Guard from supply voltage from 200 Volt to 270 Volts. Output voltage was SAME as input supply voltage. It was not doing anything. Only at very low supply voltage it was increasing voltage by 10 Volts. I contacted V Guard and they informed that design is like that. Hence in high voltage areas this stabilizer is of no use except at very high voltage beyond 270 Volts, it will cut the supply.
Consumers should see Out Put Voltage range also for the given Input supply range to know whether it is useful or not. Unfortunately, very few stabilizers indicate output voltage range for given input supply range. Like VG 400 shows, Input supply range as 170 V to 270 V. But output voltage range is not indicated on Stabilizer Body. Hence consumer does not, what will be out put voltage when input is 170 Volts or 270 Volts. Not indicating output voltage range amounts to hiding information from consumer and unfair practice.

I want to know which mixer grinder is better (750w or 500w) of any brand? Please reply quickly...

3
Abhishek Jain (Mod)

The one with more wattage will move faster. Rest all depends on what you need.

4

Thanks for prompt reply, But my concern about saving the electricity. Thanks

5
Abhishek Jain (Mod)

Although I agree that lesser wattage will consume less electricity, but then it will run slow and you need to be sure that slow running machine works fine for you. As for saving electricity, it will depend on the design and efficiency of the motor.

6

Thanks for your reply, please suggest how to choose Mixer grinder (You didn't write anything about it on your site). I select Billion 750W Mixer Grinder. Is it wise decision to save electricity?

7
Abhishek Jain (Mod)

Hi Vipin,

We do not have anything on Mixer Grinder because we have not done much research on them (on efficient technologies and efficiencies). With the limited resources that we have, it is quite difficult to expand on it right now at this stage.

Also Mixer Grinder is a very small appliance. Even with 750 watts, it will run max for 30 mins in a day (all together). And that means it will consume max 750 x (1/2) = 375 Wh or 0.375 units of electricity in a day. We have big appliances like ACs that consume 1-2 units in an hour, fans that can consume 4-5 units in a day (cumlatively), fridges that can consume 2-3 units in a day, so we targetted all the big appliances first.

Abhishek Jain ji,

Thanks for prompt reply. I am going to replace my all lighting equipment with LED. Also, going to change all fans. Also, plan to buy new refrigerator. Pl. suggests brands which are highly energy efficiency.
Lots of Thanks.

9
Abhishek Jain (Mod)

Hi Sagar,

It is not the brands that are efficient, it is the models that are efficient. Every brand has models in different efficiency ranges.

As for LED lights you will have to look at the type of LED luminaire you will be using. If you are using tubelights then Crompton has great deals on Amazon. For fans, I would suggest going for a BLDC fan (by Atomberg or Superfan), but then it is your choice to go for a new brand or not.

For refrigerator a lot will depend on the size of refrigerator you are looking at and the budget that you have.

10

Abhishek Jain ji,

Pl. inform whether any products which are suggested by you for overall performance of the product or only for efficiency of power consumption purpose.
Meanwhile a lots of thanks for such innovative ideas.

11
Abhishek Jain (Mod)

The lists for ACs, Refrigerators, Fans, Water Heaters is based on efficiency of power consumption. However, in most cases it is observed that the models from top brands and with good performance have better energy efficiency. All the other lists are based on performance.

Never buy Superfan
GES Power selling superfan on Amazon is most irresponsible seller. Sends via post office and you need to go to post office to collect the parcel.
Most irresponsible seller ever. Sent fragile item like ceiling fan through irresponsible post office parcel Today got call frm postman of Noida sec110 Yatharth Ngr post office- "cant deliver this on bycycle and it will break & will not remain useful for you. If you want you can come and collect" frm mob no 9818290010. Stay Away Better stay away from these unprofessional and unorganized sellers.
What is the guarantee that the product is shipped safely and is intact. the behavior of post man clearly shows that the department of post has no professionalism and do not care at all. And selecting such service clearly indicates the seller is just sell, make profit and forget type.
i got surprised by the fact that the courier service shown in order tracking is Fedex to cheat Amazon and in actual it is Post Office registered parcel which comes at a speed slower than bullock cart and that too with no guarantee of safe handling and no door step delivery.
Pathetic experience. please stay away for piece of mind and not experiencing this horrible experience like me.

Hello there, if you want BEST CELLING FAN then i suggest buy ATOMBERG GORILLA FAN. this fan is very best fan in market. I also happy with this product. Of you want any help you contact on whatsapp no. 7698953225

14

Which is better fan between Gorilla and Superfan X1 ? Are these fans suitable for long use like 12 hr a day in hot summers ?

15

Gorilla fan is really good fan.

16
Abhishek Jain (Mod)

They certainly are suitable for long use in hot summers. There is absolutely no issue with that. Product wise both are good, but I would rate Gorilla fan a bit higher for its build quality.

17

Hi Team,
Could you please suggest and Super efficient fan for 10x10 living room.
Thanks
Deepak

18
Abhishek Jain (Mod)
19

I have decided to go for Superfan Super X1.
Is this good/sufficient for 10X10 room in home, or do you suggest any A1 or V1 Fans

20
Abhishek Jain (Mod)

X1 is good for a 10x10 room. For a slightly bigger room V1 would be better. But for 10x10, X1 is good.

What is the meaning of power factor of .9 for super fan vs .95 of regular fans . I am planning to change my fans in my clinic to super fans . I have commercial connection . Will it affect the tariff

22
Abhishek Jain (Mod)

On commercial connections in some places there is penalty if your power factor is less than 0.9 and rebates if power factor is better than 0.95. However it is not there in every state/every city. Depends on your tariff plan. However, at 0.9 power factor there is no penalty at any place in the country. So rest assured that you will not have any problems. And in fact power saving will work well for you.

Superfan / Versa Drives is a complete fly by night operator. Deal with
them at your own risk. Their business practices are unethical.
Based
on the review(s) above, I ordered 1 Superfan for trial, thinking that if
successful, I would change all the fans in my house & in the
company for whom I work. Amazon had the V1 model Superfan @ Rs. 3630/-
delivered to me in Mumbai, on cash on delivery basis. When I contacted
Superfan directly, they promised to send the V1 model to me inclusive of
delivery @ Rs 3530/-, but I would have to deposit the cash in their
account. I have the emails to prove this. I deposited the cash as per
their email, even though their bank location was inconvenient. Superfan
is now demanding additional 10% octroi, even though the email from
Superfan stated it would be delivered at Rs 3530/-. The additional cost
was hidden from me even though I had specifically asked about costs on
the phone with them. Now I am required to pay an additional 10% or I
lose the money already paid to Superfan. I am doubtful that such an unethical
company will return my funds. I am now not sure if the package to be
delivered actually contains a BLDC fan or not. I may have to chalk up
the loss of Rs. 3530/- to experience, & deal in future only with
established fan companies. I have been doing business for 30 years, & only the most unethical companies hide costs like this. Most companies are extremely upfront about their costs.

24

UPDATE: -
Subsequent to my post on this site, I received a
communication from the company, & they agreed to supply the fan at
the original contracted price.
I am pleased to be able to say that I
received the fan yesterday, largely due to the efforts of Ms. Susila
from Versa Drives. Kudos to her! As it is the holiday season, I will not
be able to get an electrician to install the fan for a few days. When
installed, I hope to be able to review it for the benefit of the members
of this site, and other prospective buyers.

25

I must also take this opportunity to thank the Bijlibachao team. Without them, the problem could not have been resolved. I am sure that they resisted the efforts of Superfan to take down my review. Hats off to them!

26

untill and Unless Bijli bachao team would give fair reviews and non baised recommendation ,this site is going to rock.
But you know "India main sab kuch bikta hai" i doubt they will continue on this path, Once this site will become money making machine they will Start doing unethical also.
Team Please Keep doing unbiased and Fair recommendation as long as possible.

Currently Led Bulbs are being distributed under EESL Scheme, the Goverment should provide Super Effiicent Fans under EESl Scheme too with subsidy. Since Fans runs continously throughout day and night, the conventional fans consumes 75w while super fans consumes 35w max so it will help the goverment in saving maximum energy.

28
Abhishek Jain (Mod)

They should certainly start something for Fans as well.

29

I would recommend you to the lowest power consuming fan from Basil Energetics Pvt Ltd. Basil's iBreez consumes only 20w to 25w. They also provide super-efficient Air-conditioners (iChill), Refrigerators (iFreez) and lighting.

Hi Sir,

I'm interested in buying a Superfan but I'm pretty confused in determining the fan sweep that I should choose. I plan to get the Superfan for my coaching centre, whose dimensions are: Length- 12 Feet, Breadth- 7 Feet, Height- Approx. 6-6.5 Feet. Please assist me in choosing the fan sweep, so that i can choose the perfect fan to cool all my students this hot summer.

Regards,

Rajiv.

31

Dear Sir,

Thank you for your interest in SUPERFAN.

Please let us know the correct roof height to assist you with the correct model.

Regards,

Susila

From SUPERFAN

32

Not more than 6.5 feet at the most. Will it make a lot of difference between 6 or 6.5 feet?

33
Abhishek Jain (Mod)

Hi Rajiv,

Height of 6 feet is too low. If you put a fan it will be so low that it will hit people in the room. Are you sure that the height of the room is 6 ft?

34

Yeah,I know it's weird but yesterday my builder measured the height & it's 6 feet. The reason being that the upper portion has an artificial plywood partition. My builder suggested me the low roof(with partition) as apart from me(the teacher) all are children below 5 feet height.

If I have 4-5 children for my batch in the room of above dimensions, what should be the perfect sweep for the fan chosen?

35

What kind of teacher r U?. Its a common sense, U had to choose a non ceiling fan.

36
Abhishek Jain (Mod)

Hello Mr Rajiv,

It is very dangerous to go for a ceiling fan if the roof is at 6 feet. You should better go for tower fans or pedestal fans or table fans for your room.

37

Hello Superfan Team/ Mr. Abhishek,

Thank you so much for your detailed reviews on the product, which I was trying to find out for about 6 months; as I dint have proper contact.

Added to the questionnaire discussed below, I have an doubt too, does the drive will be able to withstand voltage fluctuation, surges and spikes???

I live in Trichy, Tamilnadu.

Regards,

Richard

38

Dear Sir,

Thank you for writing us .

The drive in the Superfan has an in-built EMI filter. Hence it has immunity against spikes and other disturbances in the supply line. All the components are carefully chosen to work over a wide voltage range. The drive can withstand voltage fluctuations. The drive has been tested at ETDC Chennai for immunity against Electrical fast transients, surges, and power line disturbances.

Finally we have thousands of fans working well all over India, in villages, small towns, and big cities with all the different Electricity board supplies.

Regards,

Susila

From SUPERFAN

39

Dear Madam/ Mr. Abhishek,

I am very clear technically now and I will promote Superfan as much as I can.

Thank you so much for your patience and detailed explanation through your reply, even though it took time.

Wishing all luck and success for Superfan!!

Regards,

Richard

Although I agree that lesser wattage will consume less electricity, but then it will run slow and you need to be sure that slow running machine works fine for you. As for saving electricity, it will depend on the design and efficiency of the motor.

42
Abhishek Jain (Mod)

As you mentioned, a lot depends on the efficiency of the motor. If the motor is efficient, lesser wattage will not mean slow speed. BLDC fans consume much less electricity and give equally good air delivery.

43

Hello sir, their no update till date.

44
Abhishek Jain (Mod)

Just wrote to them again. Hopefully they come back.

45

Hi Abhishek,

You stated in a comment above "The one downside of a super efficient fan is that the power factor of such fans is 0.9 as compared to 0.95 of regular fans with induction motors. It may impact commercial connections with demand charges in their tariff plan"

Would this be an issue if I were to install a Superfan V7 or X7 at my residence and would my tariff get affected? I live in in Bangalore.

Thanks,

Rehan

Abhishek Jain (Mod)

Hi,
It will not have any impact on resedential connections.

47

Where is the list of Fans ?????
