Pellet stoves contain three main components: the combustion chamber alone, a pellet storage hopper, a feeding system, and heat distribution mechanisms that use fans or blowers. Pellet manufacturers produce small cylindrical pieces by compacting different biomass materials, including sawdust, wood chips, and agricultural waste, to create pellets as a final product. The manufacturing process involves moisture subtraction followed by material combination, which leads to high-pressure material binding.
The pellet stove enables the pellet feeding process through the combustion chamber before igniting and creating heat. The generated heat is distributed by either a fan or a blower system across an entire room or throughout the entire house.
How Much Electricity Does a Pellet Stove Use?

During operation, a pellet stove consumes electricity at levels ranging between 100 watts and 500 watts based on the properties of each specific model and feature set.
Calculating the Cost of Running a Pellet Stove
Calculating the cost of running a pellet stove involves considering several factors, including the price of pellets, the stove's efficiency, and the desired heating output. Here's a step-by-step guide to help you calculate the cost:
- Determine the pellet consumption rate: Check the manufacturer's specifications or user manual to find the pellet consumption rate of your stove. It is usually measured in pounds per hour (lbs/hr) or tons per season.
- Find the price of pellets: Check the current price of pellets in your area. The price is usually quoted in cost per ton or cost per bag.
- Calculate the hourly pellet usage: If the pellet consumption rate is given in tons per season, divide it by the number of hours in the heating season to get the hourly pellet usage. For example, if the stove consumes 3 tons of pellets in a season that lasts 1,500 hours, the hourly pellet usage would be 3 tons / 1,500 hours = 0.002 tons per hour.
- Determine the cost per hour: Multiply the hourly pellet usage by the price per ton or bag to get the cost per hour. For example, if the price of pellets is $200 per ton, the cost per hour would be 0.002 tons per hour * $200 per ton = $0.40 per hour.
- Consider the stove's efficiency: Pellet stoves have different efficiency ratings, typically 70% to 90%. Multiply the cost per hour by the reciprocal of the efficiency (in decimal form) to account for the stove's efficiency. For example, if the stove has an efficiency of 80%, the adjusted cost would be $0.40 per hour / 0.8 = $0.50 per hour.
- Optional: Account for other factors: If you want to consider additional costs, such as electricity usage for fans or maintenance expenses, estimate these costs separately and add them to the calculated cost per hour.
