Wood & Pellet Stove Economics: When Burning Beats the Utility
Updated August 2026
In plain numbers: Bought at typical prices, pellets and seasoned firewood deliver heat slightly above natural-gas cost and comfortably below oil, propane and resistance electric — and free wood beats everything. Stoves pay best as zone heaters: warming the living space through evenings while the central system idles low routinely trims 20–40% off winter bills. The traps are buying badly (green wood, short cords, off-brand pellets) and ignoring the real labor of the wood lifestyle.
Cost per BTU, without romance
A cord of seasoned hardwood carries roughly 20–24 million BTU; at typical prices and a modern stove's ~75% efficiency, delivered-heat cost lands near or a bit above natural gas and clearly below oil and propane. Pellets (about 8,000 BTU/lb, ~$5–7 per 40-lb bag by the ton) land in the same neighborhood with less variance — the fuel is standardized in a way cordwood never is.
The numbers swing on buying skill: green (unseasoned) wood wastes a third of its energy boiling off water, 'face cords' masquerade as full cords, and bargain pellets with high ash content clinker up stoves and burn short. Moisture meters ($20) and reputable dealers are the whole defense.
Zone heating is where stoves earn their keep
A stove heating the rooms you actually occupy — while the whole-house thermostat drops to 60°F — is the winning pattern: the expensive system stops heating empty bedrooms, and the cheap local BTUs cover the living space. Households running this play consistently report 20–40% seasonal savings, more where the displaced fuel is oil or propane.
Trying to heat a whole modern house from one stove usually disappoints: heat pools in the stove room while far bedrooms freeze, and the labor scales badly. Buy the stove for the zone, keep the central system for the envelope, and let each do its job.
The labor line item and the fine print
Wood heat's true price includes hauling, stacking, seasoning a year ahead, daily loading, ash disposal and an annual chimney sweep (creosote fires are the non-negotiable reason). Pellets soften most of that — hopper feeding, thermostatic control — at the cost of electricity dependence and a machine with moving parts.
Check the paperwork before the purchase: modern EPA-certified stoves burn far cleaner and more efficiently than older units (many jurisdictions restrict or ban pre-certification stoves), insurance wants a permitted installation with proper clearances, and rebate programs periodically subsidize upgrades to certified models.
FAQ
Is heating with wood cheaper than gas?+
Bought at typical prices, wood lands near or slightly above natural gas per delivered BTU — the win comes from free/cheap wood sources or from zone-heating that lets the central system idle. Against oil, propane or resistance electric, wood wins clearly.
How many cords of wood does it take to heat a house?+
A stove zone-heating a living area typically burns 2–4 cords a winter; whole-house wood heating in cold climates runs 4–8. A cord is a stacked 4×4×8-ft — 128 cubic feet — and 'face cords' are a third of that.
Are pellet stoves worth it?+
For automated wood-class heat, yes: pellet cost per BTU sits near cordwood with far less labor, thermostatic control and cleaner burns. Budget for electricity dependence, yearly maintenance and hopper refills.
