Heatwave coming? Don’t want to see your electricity bill skyrocket? Here are 10 practical tips to stay cool without breaking the bank.
1. Choose an energy-efficient air conditioner
An evaporative air conditioner (like the Silent 3-in-1) uses 65 W. A wall-mounted AC installed: 1500-2500 W. Difference: 30× less.
2. Set the thermostat to at least 26°C
Every degree below 26°C = +7% consumption. Set it to 26°C and add a fan for a cooling sensation.
3. Use night/sleep mode
Night mode reduces power by 30-50% while you sleep. All Coldest Breeze models include this mode.
4. Close shutters during the day
20% savings: closed shutters = room doesn’t heat up = AC works less.
5. Use the timer
No need to run the AC all night. Set it for 4-6 hours — you’ll be in deep sleep after that.
6. Maintain the filter
Dirty filter = +30% consumption. Rinse it with water every 2 weeks in summer.
7. Cool only one room
Instead of investing in a wall AC for the whole apartment, buy a portable air conditioner for the bedroom (where you spend 8 hours a night). Savings: 80% of total cost.
8. Combine with a ceiling fan
The fan creates a perceived temperature drop of 3°C. You can set the AC 2°C higher = 14% savings.
9. Take advantage of off-peak hours
Electricity costs 30% less at night (off-peak hours). Program your AC to cool before peak hours.
10. Insulate windows
Thermal insulating films on windows: €8-15 per window, 20% savings on the bill. ROI in one summer.
