Energy Saving Tips

Use Inverter ACs for Hot Climate

Tamil Nadu’s high temperatures lead to heavy cooling needs. Inverter ACs consume less power and cool faster.

Switch to Solar Water Heaters

Coastal sunlight is strong throughout the year. Solar heaters significantly reduce geyser electricity usage.

Use Ceiling Fans Before AC

Running fans first cools rooms faster and reduces overall AC run time by 20–30%.

Choose BLDC Fans

BLDC fans use 60% less power and work efficiently even during voltage fluctuations common in some districts.

Avoid Using Iron During Peak Hours

Electric irons consume high wattage. Using them during non-peak hours helps reduce monthly bills.
