What are the operational costs of your snow melting systems?

The average operational cost for a snow melting system is approximately $0.18 per 100 square feet per hour.  This figure is based on a system producing 22 watts/sq. ft. or 73.7 BTU’s/sq. ft. with a kwh rate of $0.08 per hour (the national average kwh is $0.08/hour).  If you know the square feet of the area you wish to heat and your kwh rate, you can calculate the operational costs with this formula: heatable sq. ft. times watts/sq. ft., divided by 1000, times your kwh rate.
