Electric Steam Humidifier
This system uses electricity to heat the water and create steam. Internal replaceable steam cylinders with an electric grid are used in most of the manufacturers units.
Gas Fired Steam Humidifier
Typically a stainless steel low pressure boiler design using natural gas as its energy source.
Operating Cost Comparison
Electric Gas
Pounds per Hour 800 800
Utility rates used $0.10/kwh $0.65/therm
Yearly running time 2000 hrs 2000 hrs
Energy use per hour 276 kwh 9.52 therm/hr
Yearly Operating Cost $55,200.00 $12,376.00
Energy Cost Savings Natural Gas vs Electric $42,824.00
Rates can be changed to reflect your actual average utility cost.
Hours of operation will vary according to your requirements.
Payback
Assume the electric steam system cost approximately $35,000.00 to install. The gas fired system is typcially twice the electric and would be $70,000.00.
Payback would be less then a year at the above operating conditions.
The operating and payback analysis is for a system with humidifiers and remote blower packs that are wall mounted.
