Wood heat is the only fireplace category where the fuel can be free, and that single fact decides most of the math. If you buy your fuel, a pellet stove usually runs cheaper than a wood stove. If you cut your own wood, nothing beats the wood stove, as long as you value your Saturdays at zero dollars an hour.
Wood stove vs pellet stove
The efficiency gap is real: modern pellet stoves run around 80 percent efficient, wood stoves closer to 60. A ton of pellets costs about the same as a cord of wood, roughly $250 in most markets, but delivers more usable heat. Pellet stoves also hold a fire unattended for a day or more with a hopper feed. Our pellet stove cost guide runs the full numbers, from the unit and install through a season of fuel.
The trade-offs going the other way:
- Pellet stoves need electricity for the auger and blowers. No power, no heat, unless you have battery backup. A wood stove works in any outage.
- Pellet stoves have moving parts that wear and need cleaning and occasional repair.
- Wood stoves burn anything seasoned, including the tree that fell in your yard. Pellet stoves burn pellets you must buy, haul, and store dry.
The full head-to-head with annual cost scenarios is coming this fall. Until then, the heating cost calculator linked under Related reading runs the fuel math with your local prices.
The firewood math
The honest planning numbers: a typical family home heating mainly with wood burns 4 to 8 cords a winter. In cold climates figure 2 to 3 cords per 1,000 square feet for the season; in milder regions 1 to 2. A tight house with an efficient stove beats those numbers, an old farmhouse with single-pane windows eats through them.
Wood species matters as much as quantity. Oak and maple burn hotter and longer; pine and poplar burn fast and light. Whatever you burn should be seasoned to below 20 percent moisture, both for heat output and because wet wood is the creosote machine that dirties your flue.
Before the install
Stove installation cost is dominated by venting, not the stove, and our wood stove installation cost guide breaks down unit prices and install labor line by line. If your chimney needs a stainless liner, that is $1,500 to $5,000 of the project right there. Add hearth pads, clearances to combustibles, and permits. Buy an EPA-certified stove: cleaner burn, less creosote, and dramatically less smoke. The EPA’s Burn Wise program is the reference for clean-burning practices.
One non-negotiable: wood burning means yearly chimney attention. The Chimney and Venting hub covers inspection schedules, sweep costs, and the warning signs.

Frequently asked questions
Which is cheaper to run, a wood stove or a pellet stove?
If you buy your fuel, the pellet stove usually wins: about 80 percent efficiency against roughly 60 for wood, and a ton of pellets outheats a similarly priced cord of wood. If you have free or cheap firewood, the wood stove wins easily.
How many cords of wood does it take to heat a house for the winter?
Most homes heating primarily with wood burn 4 to 8 cords a season. Plan on 2 to 3 cords per 1,000 square feet in cold climates and 1 to 2 in milder ones, then adjust for your insulation and stove efficiency.
Do pellet stoves need electricity?
Yes. The hopper auger, ignition, and blower fans all run on power, so a pellet stove goes dark in an outage unless you add battery backup. Wood stoves keep working regardless.
What firewood burns longest?
Dense hardwoods like oak, maple, and hickory burn hotter and longer than softwoods like pine or poplar. Whatever the species, it needs to be seasoned below about 20 percent moisture to burn well and keep creosote down.
