Electric blower,on insert

Your question can better be answered if you look on the motor and tell us the amp rating of the motor- or look it up on the manufacturer's page or whatever. But the math is simple enough. Or what is the rated wattage? Give us a number. Let's say it draws a half amp. That's 60 watts. We're talking 120 volts AC service, right? There are 16.7 hours of run time in a kilowatt hour for that size motor. So let's assume you pay 15 cents for a kilowatt hour from your power company. I'm getting 0.828 cents per hour to run that hypothetical fan. At 12 hours per day times 30 days in a month, that is 3.23 dollars per month to run it, if I did my math right. Your electric bill is 3.23 higher per month with that hypothetical motor. Not great but not bad either...

Even if it ran continuously, 24/7, this hypothetical motor would 'only' cost you 6.46 per month. I think 12 hours is a good guess, though.

A dollar 280 at most, it may increase your monthly bill, but not by much when you think about other heating costs, so don't worry....

I think the short answer is the cost is way below trivial, but I had the same question too. I have a Killawatt device, and the max draw on my old stove (one blower) was 80 watts. I run it based on noise, and that setting ends up around 60 watts. I tune off one incandescent bulb somewhere in the house, and the net increase is zero!

On the other hand, I checked the wife's Koi pond and that pump motor was 450 watts. 24/7 until freezing temps. That works out to $1/day, I think.

Sometimes I take my stove energy savings and make toast!!

I run mine full bore most of the time except on reload. I can't even calculate the difference on my electric bill. Certainly nothing that kicks me in the balls and makes my eyes bug out and head spin.

If you don't run it at all the replacement cost is near zero. Just sayin.

I checked my blower motor with a Kill-a-Watt meter a few weeks back. It is 90W on full, and 30W on the lowest setting. In the deep winter, mine will run on low all the time (fire always going). But even then, that is only 720 W/day, or about 21 kWh/mo, at a cost of about $3.
