Electricity Saving Tips For Homes And Offices

Choose the right Regulator for Ceiling Fan for Electricity Saving

By on March 6, 2014

Fan Regulator Ceiling fan is one of the most common appliances in Indian household. Being a tropical country, India relies a lot on ceiling fan and there is a ceiling fan in every room in the country. When we go and buy a ceiling fan, we also get a regulator along with it. Regulators are of different types, and different ceiling fans come with different types of regulators. Most people typically do not care about the regulator, but it is very important to know that even the regulator can waste electricity and can increase your electricity bills.

Good news is that you can always refuse to take the supplied regulator and can get equivalent discount, and replace it with an efficient one. But for that you need to know about the types of regulators.

How does a Fan Work?

A ceiling fan has an electric motor and metallic blades connected to it. When we switch on a fan, the voltage difference causes the current to pass through the motor and the fan rotates. The regulator controls the voltage that makes the current flow less or more. Lower the voltage lower the speed of the fan. So a regulator controls the voltage levels for the fan.

Types of Regulators

There are 3 types of regulators available in the market today: Electric Regulator, Step Type Electronic Regulator and Movable Electronic Regulator. All 3 have different ways of controlling the fan speed and thus the efficiency with which they manage electricity consumption differs. From price perspective Electric regulator is the cheapest, but of all three it is the most inefficient regulator. We are in process of compiling information related to price impact and will update that as well very soon. But first let’s look at all the three types:

Electric Regulator

Traditional regulators that were there in our homes in the past were mostly of this type. These regulators have resistors to decrease the voltage for the ceiling fan. The resistor heats up while decreasing the voltage and thus the electricity saved by reducing the fan speed is lost as heat in the regulator. The internal heat also damages the regulator in long run. These regulators are also bulky in size. They come for as low as Rs 40 a piece.ElectricRegulator

Electronic Regulator

Electronic regulators are the latest type of regulators available in the market. These are much smaller in size than the electric regulators. Electronic regulators use capacitors instead of resistors to decrease the voltage. Capacitors regulate the fan speed by regulating the waveform of power supply. These do not get heated up and thus save electricity when the fan is running at lower speeds (at higher speeds electricity consumption of fan is the same with both regulators).  These regulators save up to 40% at speed 1 and about 30% at speed 2 compared to electric regulators. There are 2 types of electronic regulators available:

    1. Movable Type: These regulators move smoothly and there are no stepped number (1 to 5) provided on theem. These regulators are better than electric ones but still can cause some distortion to the movement of the motor that causes it to heat up. This type typically costs Rs 100 apiece.MovableType
    2. Step Type: These regulators have numbered speed steps (typically 1 to 5). These regulators provide lower distortion to the movement of the motor and thus less heating. These are the most efficient type of regulator. This type typically costs Rs 200 apiece.ceiling_fan_regulator

If you run fans at low speeds in your house then a step type fan regulator is the best electricity saving option for you. Savings in electricity bills can recover the extra price you pay for it.Infographic11.png.png

    why do regulators of fan gets heated?

    • Abhishek says:

      If it is a resistor based regulator, then when current passes through a resistor, heat gets generated. It’s like when tyre runs on road, it gets heated.

    Can a ceiling fan with electronic regulator be operated by two 2way switches ?

    Mr:Jain Thanks a lot Sir.
    I Shall go through it thanks once again.:)

  4. Reddy.SM says:

    Sir Am having electronic regu. lator( not step type). Here my problem is. When I turned on the regulator in just minimum speed, later (aprox. 04:00 he’s) on all of sudden the fans speed will be very high.(for ex:( When I turned fan on by 11:00. pm around 03:30. Morning its runs in more speed.
    Thank you sir.
    Regards:Reddy

      Hello Mr Reddy,

      Whatever is happening in your regulator is quite strange. It seems something is wrong in the regulator. Would suggest you to change it to a step type regulator.

    can it b possible to design digital regulator for ceiling fan? is it advantageous one?

    • Abhishek says:

      It certainly is possible. But ultimately won’t it will have electronic circuitry? Can’t see any advantage over regular electronic regulator.

      Regards,

    can we replace an old crompton greaves regulator with a new one? are regulators available in market, coz i’ve learnt that new fan never comes with regulators!

    • abhishekjain203 says:

      You can certainly replace your old regulator with a new one. They are available in market. All brands like Anchor, Roma, etc make them. You can try them out.

      Regards,

    how about connecting a fan regulator to a 100 or 60 watts bulb to make it dimmer and to save current

    • abhishekjain203 says:

      Well I would suggest using a CFL or LED instead of 100 or 60 watts bulb. That will save you far more electricity than using a regulator as a dimmer.

      Regards,
      Abhishek

    Interesting post. the discussion part is really informative. Electrical Fan heaters

  9. Vikrant Latkar says:

    Can I add another smooth regulator to the existing regular regulator so that I can control the fan speed more accurately?

    how to join the regulator in
    Ceiling fan

    • avinash says:

      Fan regulator is connected in series to the fan. You have to connect the live or phase wire from the board-switch-end with one wire of regulator and the other wire in the regulator to the ceiling fan.The neutral wire is directly connected the other terminal of ceiling fan.
