Comparison Of Solar Water Heaters With Oil Fired Boiler

System capacity

125 LPD

Average output temperature

65 deg. C.

Average input temperature

25 deg. C.

Total heat gain

System cap. x temp. difference

= 125 x 40 kcal = ,5000 kcal

Approx. total cost

Rs. 25,000/- (US$1=@Rs.55.00)

Boiler efficiency

@ 80 %

Operational days in a year

300

Calorific value of oil

10280 kcal/kg

Purchase Cost

@ Rs. 30- per liter

Specific gravity of oil

0.8

Oil required per day

= Heat gain/ (calorific value x sp. gr. x boiler efficiency)

= 5000/ 10280 x 0.8 x 0.8

= 0.76 liters

Saving per day

= 0.76 x Rs. 30/- = Rs. 22.80

Saving per year

= 22.80 x 300 = Rs. 6840/-

Payback period

= Net cost / saving per year

= 25,000/ 6840

Payback period

= 3.65years

Payback period with subsidy

2.77 years
