Fuel Saving


Fuel Saving
The fuel saving depends on the fuel used by the industry
For simplicity we divide fuel into 3 group

High Cost fuel
HSD, PNG / CNG, Electricity
- They have a consistent quality
- Huge and rising price variations
- Boiler efficiency 80 to 85%
- Replacement of this Fuel with Solar Thermal has pay back of 2 to 3 years
- Replacement of this fuel with Heat Pump has a pay back of 1 Year
- Hybrid solar & Heat Pump has pay back of about 2 years

Medium Cost Fuel
Furnace Oil, LDO
- The quality depends on the sourcing & the quantity purchased at one time.
- Huge and rising price variations
- Boiler efficiency 70 to 80%
- Replacement of this Fuel with Solar Thermal has pay back of 3 to 4 years
- Replacement of this fuel with Heat Pump has a pay back of 2 Year
- Hybrid solar & Heat Pump has pay back of about 3 years

Low Cost Fuels
Wood, Briquettes, Coal
- The Quality is extremely variable depending on the manufacturer, Source of the material, Moisture content & Excipients added
- The actual calorific value obtained is about 40% of the theoretical value. Hence actual checking of the consumption of the fuel against the heat generated is essential before concluding the payback.
- Boiler efficiency 50 to 60%
- Replacement of this Fuel with Solar Thermal has pay back around 5 years
- Replacement of this fuel with Heat Pump has a pay back of 3 Year
- Hybrid solar & Heat Pump has pay back of about 4 years
