Meaning behind star ratings on electrical items

Electrician Phoenix

Many electrical household appliances, like refrigerator and air conditioner, are now seen with stars on them. There are 1 to 4 stars on them, and all of them vary. For someone who can afford those kinds of appliances, it is often heard that we should buy only those which have 3 or more than 3 stars on them. But have we ever wondered why? The meaning behind the stars is efficiency. The higher the efficiency, the more the star rating. The appliance with a higher star rating is guaranteed to consume less electricity as compared to appliances with a lower star rating. To explain further the meaning of these star ratings, let us take an example of a fridge. A fridge consumes electricity for twenty four hours each day. It is the highest electricity consuming appliance in the household. It is essential for keeping food fresh as new and cold. To a fridge, stars are awarded under volume categories of litres. For example, each category of 100 litre fridges has its own star rating, depending on its efficiency, litre-wise. A fridge that has higher stars consumes less electricity. So, a fridge of 100 litres having 5 stars means it consumes less electricity than all the other less than 5 stars-rated fridges in the 100 litre category. All of the various appliances have different energy star ratings.
The manufacturers are required to put on the energy star rating labels on all of their electronic appliances. These star ratings help consumers educate themselves and spread awareness about the efficiency of the product and to use more energy efficient products. The ratings are updated timely. A lot of norms and standards have to be followed for rating an appliance. There are some appliances which need to have a star rating and others that don’t need any.
The appliances which need a star rating are:

  • Air conditioners
  • Refrigerators
  • Color TV
  • Tubular florescent lamps
  • Distribution transformer
  • CST AC
  • Electric Geyser

There are small as well as big labels. Big labels are used mostly on refrigerators, geysers, air conditioners and washing machines. These labels also indicate the approximate consumption of energy units per year. Big labels indicate that the appliance consumes more energy as various other appliances. Small labels are found on appliances which consume relatively less energy, like ceiling fans, computers, laptops, tube lights, and television. Big labels also indicate the appliance/type, brand name, model/year, cooling capacity o the appliance (if air conditioner or fridge), its power consumption, whether it has a variable speed compressor or not, and whether it has a heat pump or not. All the labels have a label period, where the dates are printed for the validity of the label. All the labels need to have a trademark for validity.
There are many cases where big companies have failed in energy rating tests. Some have even failed to live up to the energy rating they showed on the label. So, energy rating labels are very reliable in nature. Also, as a manufacturer, it is their duty to show you good quality and energy efficient products. It is also their responsibility to not sell you defective products. Its good to always call Electrician Phoenix if want energy efficient electric appliances for home.
