How Many Watts Does a Pellet Stove Use?
Pellet stoves require electricity for the auger, fan, and igniter. While they produce far more heat than they consume in electricity, they still need backup power during outages.

Battery Runtime Examples
| Battery Size | Voltage | Runtime at 100W |
|---|---|---|
| 100Ah | 12V | 10 hours |
| 200Ah | 12V | 20 hours |
| 400Ah | 12V | 40 hours |
* Assumes 85% inverter efficiency and 80% depth of discharge for LiFePO4 batteries.
Pellet Stove Power Tips
- •Igniter uses 300-500W but only runs for 5-10 minutes at startup
- •Running power is only 50-100W for auger and fans
- •A 100Ah battery can run a pellet stove for 8-12 hours
- •Consider a battery backup specifically for pellet stove operation
- •Some models have optional battery backup kits available
Frequently Asked Questions
Can a pellet stove run on battery?
Yes, easily. A 100Ah lithium battery with a 500W inverter can run most pellet stoves for 10+ hours. The startup surge is brief, and running draw is low.
What size inverter for pellet stove?
A 500W pure sine wave inverter handles most pellet stoves. The 300-500W igniter surge is brief, and running draw is under 150W.
How much power does a pellet stove igniter use?
Igniters draw 300-500W but only for the 5-10 minutes at startup. Once the fire is lit, power drops to 50-100W for auger and fans.
