The Breakdown of How Electricity is Used in a MagnuM Pellet Stove. The fan motors, auger motor and stirrer motor (if standard) take approximately 2.5 amps to 3.0 amps to operate. Voltage x amps = watts, so 110v x 2.75 amps = 303 watts of usage per hour. With the average price of a kilowatt at $0.08, the average electrical cost to run a stove would be .303kw x .08 = 2.42 cents per hour. If a stove ran for 24 hours in a day it would use approximately 58 cents per day (2.42 cents x 24 hours =58.176 cents).
