With rising fuel costs I thought this little table may be of value..
The cost comparison is based on an incremental increase of existing fuel. Pressure washers compared use the same pump/ motor and have similar heat rise values.
Electrical rate is per kWh from Chicago, IL area electric utility. The unit is 72 kW or 245,670 Btu equivalent.
Natural gas rates per cubic foot from Chicago, IL area utility. The heater burns 34.2 cubic feet/ hour or 9.7-m3/ hour at 345,500 Btu.
Kerosene and Diesel fuel price reflect Chicago, IL area retail cost per gallon. The units consume 2.25 US gallons/ hour.
LPG rates per gallon from Chicago,IL supplier. The units consume 16 pounds per hour at 345,500 btu.
FUEL COST/unit HOURLY DAILY (8 hours)
Electric $0.04672 $3.36 $26.88
Natural gas $0.07542 $2.58 $20.64
Diesel $1.80 $4.05 $32.40
Kerosene $2.55 $5.74 $45.92
Propane $1.94 $7.49 $59.92
Hope this helps? Cheers.
