Calculation of Energy & Amount Saved On FPC
1 person = 1 bucket of hot water (Minimum) (about 20 liter) per day (600C)
1 bucket of hot water = 1 unit (minimum) of electricity = 1 KWh = Rs. 4.50
So, 5 persons = 5 unit per day = 5 x Rs.4.50/- = Rs. 22.5/- per day
Savings after 1 year = 300 days x Rs.22.5/- = Rs.6750/- per year
(Below results are achieved by various practicals and testings done by us. Results may alter at different conditions, so no guarantee for above figures)
