But a hopper fire from over drafting is.

.09 cents per kilowatt hour? Thats half of what i pay in my neck of the woods.coalishot wrote:Did math on inducer motor. it is rated at .43 amps at .09 cents per kilowatt hour (for now in Pa see this link http://energy.cas.psu.edu/focustwo.html ) running 24/7 for 31 days a month I come up with $3.45 a month to run it. The combustion fan on my liberty is much smaller but I dont see amp or watt rating but it must be about half the draw of this motor. The blower motor is in housing and i cant see that tag either but i would say it is probably twice the use of the inducer i will put amp probe on both and get actual readings and post some day soon. Also rated watts and amps are usually max and most motors run under rated amps/watts.
