The variable speed motor will typically use only about 75 watts of power per hour, compared to a conventional blower that uses about 400 watts. Thus, over the course of one year, you can expect to save money on your electric billwith a variable speed motor.
Use this simple formula to calculate your potential energy savings, based upon your existing power costs per kilowatt-hour:
2,847 kilowatts* X $.80/kW/h = up to $240.00 in energy savings, based upon your existing power costs per kilowatt-hour:
Savings are based on an HVAC systen that is always operating either in heating, cooling or "fan" mode.
*Average kilowatts saved per year is calculated by saving 325 watts of power per hour with a variable speed motor using 75 watts per hour, versus conventional blower motors using 400 watts per hour, times 8,760 hours in a year, equals 2,847,000 watts/1000, which equals 2,847 kilowatts.
For any furnace, providing maximum comfort means achieving the proper amount of airflow. This is true for both heating and cooling operations. Unlike conventional single speed motors, a variable speed motor runs at a wide range of speeds. Using intelligent technology, it continually monitors incoming data from your heating and cooling system, and it automatically makes the adjustments necessary to meet your comfort needs. The motor varies the amount of air circulated, compensating for factors like dirty filters by increasing speed. Put simply, it delivers just the right amount of air necessary to provide the desired level of heating and cooling comfort.
