| S/no. | Items | Electric Resister | Diesel Boiler | Air Energy Heat Pump | Solar | Remarks |
| 1. | Power Source | Electricity | Diesel | Electricity | Sunshine | Under Opulent Sunshine |
| 2. | Energy Consumption (everyday) | 232.6 kwh | 19 L | 58.2 kwh | 0 |
Consumption of solar electrical controlled facility can be ignored |
| 3. | Cost (everyday) | 2791.2 NPR | 1463 NPR | 698.4 NPR | 0 | Price of electricity: 12 NPR/kwh, Diesel: 77 NPR/L calculated as per one heating everyday. |
Note:
1)Enery,Q = mc( t1-t2 )
= 5000×4.1868×( 55-15 )
= 837360(KJ)c = 4.1868 is specific heat coefficient of water.)
2)1kw/h = 1kwh = 3600KJ
3)837360÷3600 = 232.6kwh
4)837360÷43984 = 19L(Calorific value of 1L diesel is 43984KJ.)
5)232.6÷4 = 58.2kwh(Normal electricity consumption of air energy heat pump is 1/4 of electrical heating.)
