❄️ Why Set AC Minimum at 20°C?
Lowering the AC temperature beyond 20°C leads to:
-
Excessive energy consumption
-
Higher electricity bills
-
Strain on national power grids
-
Greater environmental harm
It’s been found that every 1°C increase in AC temperature can save up to 6% of electricity.
🔥 Why Limit Room Heaters to 28°C in Winter?
Similarly, during winters, using room heaters at 30°C or more may feel cozy but:
-
Consumes a huge amount of power
-
Creates sharp indoor-outdoor temperature differences, which may cause health problems
-
Adds to electricity load during winter peaks
Setting the heater at a maximum of 28°C helps maintain a balance between comfort and energy use.
🏠 How It Affects You (AC + Heater)
| Appliance | New Limit | Why It Matters |
|---|---|---|
| Air Conditioner | Not below 20°C | Reduce overcooling and save power |
| Room Heater | Not above 28°C | Avoid overheating and energy loss |
These rules apply across India and are expected to be monitored in large public spaces and government buildings first, before being gradually enforced in residential areas.
