3 Star vs 5 Star AC Power Consumption: With the heat increasing day by day, AC has become not just a luxury but a necessity in many homes. In such a situation, while buying an air conditioner (AC), the first thing most people look at is its price, but even more important is its star rating. This rating decides how much electricity your AC will consume and how much will be the electricity bill every month.
Amid rising electricity prices in India, choosing an AC with the right star rating can lead to good savings in the long run. In such a situation, the biggest question is whether it would be better to buy a 3 Star AC or a 5 Star AC. So today let us tell you how much electricity is saved in 3 Star and 5 Star AC in 1 hour.
What does the star rating of 3 Star and 5 Star AC mean?
The star rating of air conditioners is decided by the Bureau of Energy Efficiency (BEE). This rating tells how well an AC provides cooling by consuming less electricity. 5 Star AC gives better cooling in less power. It consumes about 10 to 28 percent less electricity than 3 Star AC. 3 Star AC is cheaper to buy, but its electricity cost can be high if used for a long time. Star rating is decided on the basis of ISEER (Indian Seasonal Energy Efficiency Ratio). The higher the ISEER, the less electricity the AC will consume.
How much electricity is saved in 3 Star and 5 Star AC in 1 hour?
If you use 1.5 ton AC, then 3 Star AC consumes approximately 1100 to 1200 watts of electricity in an hour. Whereas a 5 Star AC consumes approximately 800 to 900 watts of electricity in an hour. In such a situation, 5 Star AC consumes about 15 to 25 percent less electricity than 3 Star AC, which can lead to good savings in electricity bills in the long run.
