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)

Capacity In LPD(Properties)	1050	1500	2000	3000
