yap, best ROI in the best perfect world!!!

in a perfect world, the electronic component will stay in perfect working condition for a perfect optimum 10yrs, it will never go faulty for the next 10 perfect years....    

but in reality mostly after 5 yrs above, once goes bad on the control board, they will chg to a new fan again, and again

save 2400??!! more like a marketing gimmick to lure those who always live in a perfect world...!!!

   

Please calculate for me.  I'm using Panasonic DC fan for the past 2 years.

My living area fan is switched on 24x7 because I have a dog in the house.

How much I saved?

LOL those who said dc ceiling fan useless must be never use inverter aircond before.

its 50% more efficient than AC, if ur house got 6 DC fan, u only pay like 3 AC fan.

example 40w * 6 = 240w. (this is highest speed for DC fan, produce 23X rpm).

the rest u calculate la, u use fan everyday, atleast 12 hours, if all eq in ur house is inverter, say example 3* 1hp inverter aircond, 1* 1.5hp inverter, 1  inverter fridge, 1 inverter washing machine, 2 inverter water heater, and 6 dc fan,
and use 5 fans, 4 aircond everyday for 8 hours, ur bill will only cost around rm250 - 300. I use all above except the dc fan, bill around rm250.

surely will use dc fan later for my new house
