Water Heating cost comparision between fossil fuels and Heat Pump
Heat Pump needs 25% Electrical input to drive compressor to transport heat from source to destination. The balance 75% of heat collection is done from Renewable Energy Sources like Ambient Air, Lake, River, Ocean or Industries Process Waste Fluids / Vapor.

Name of Fuel | Calorific Value | Fuel Efficiency / COP | Actual Heat Gain | Qty of Fuel required | Unit Fuel Cost | Cost of Heating |
High Speed Diesel | 10,400 Kcals per kg | 0.8 | 8,320 Kcals per kg ( 6,656 Kcals per Ltr) | 0.45 Ltr / hr | 95.82 Rs / Ltr | 43.19 Rs / hr |
LPG | 11,200 Kcals per kg | 0.9 | 10,080 Kcals per kg | 0.3 Kg / hr | 88.58 Rs / Ltr | 26.36 Rs / hr |
Electrical Heating | 860 Kcals per kw | 0.85 | 731 Kcals per kw | 4.1 kw / hr | 12 Rs / unit | 49.25 Rs / hr |
Heat Pump | Compresspor power input in Kw | 3.5 | 3010 Kcals per kw | 1 Kwh | 12 Rs / unit | 12.0 Rs / hr |
Longer you use heat pump, More you save and faster you recover investment.
Move renewable heat with decarbonized grid & mission NET – ZERO shall be in reach.
