If you want one freestanding stove to heat a Colorado home or cabin, here is the short answer. A wood stove wins when you have cheap or free wood, a strong back, and a real chance of losing power for days. A pellet stove wins when you want thermostat controlled heat from a live flame and you can keep the lights on. A gas stove wins when you want heat at the push of a button, no fuel handling, and the smallest venting job.
The rest of this guide is the detail: what each fuel costs to run, how each one vents and what that does to the installation bill, how much of your week each one eats, and how each behaves at 5,000 to 9,000 feet when the power is out.
One scope note. Our pellet stove guide covers pellets in depth, our wood stove insert guide covers units that slide into an existing fireplace, and our EPA certified wood stove guide covers emissions certification. This article stays on the three-way choice for a freestanding unit on a hearth pad.
Wood vs Pellet vs Gas Stove: The Head to Head Table
Numbers below are typical industry ranges. For what our own installations cost, see our chimney and fireplace pricing page rather than any figure here.
Table 1. Wood, pellet and gas freestanding stoves compared across the factors that matter most in Colorado.
| Factor | Wood stove | Pellet stove | Gas stove |
|---|---|---|---|
| Fuel cost driver | Price of a cord, or your labor if you cut it | Price per 40 lb bag or per ton | Natural gas therm rate or propane per gallon |
| Heat output and control | Highest peak output, hardest to fine tune | Moderate, steady, thermostat controlled | Moderate, instant, precise |
| Needs electricity | No | Yes, for auger, fans and igniter | Usually no for the burner, yes for the blower |
| Daily effort | Haul, load, tend, empty ash | Fill hopper, scrape burn pot | Press a button |
| Maintenance | Annual sweep, gasket and baffle checks | Weekly cleaning, annual teardown | Annual service of burner, pilot and vent |
| Venting | Class A insulated chimney | Pellet vent through wall or roof | Direct vent through wall or roof |
| Footprint and clearances | Largest, longest clearances | Medium, tight clearances on many models | Smallest, tightest clearances |
| Power outage | Full heat, no change | Off without battery backup or generator | Burner often runs, blower does not |
| Altitude behavior | Weaker draft, needs dry wood and chimney height | Needs high altitude setting or feed adjustment | Derated by the manufacturer above a stated elevation |
| Air quality rules | Must be EPA certified, subject to no burn days | Usually exempt from no burn days | Not affected |
On heat itself: a big steel wood stove out heats the other two, which matters in a drafty cabin at 8,500 feet, but it is the hardest to keep steady. A pellet stove holds a room within a couple of degrees, with fan noise as the tradeoff. A gas stove is the most precise, at full output in a minute.
Mountain Cabin or Metro Home: Why the Answer Changes With Your Address
Metro Denver and the suburbs
In Aurora, Lakewood or Thornton, natural gas is at the curb, outages are usually short, and wood has to be bought at retail and stacked in a yard that may not have room. Gas stoves make the most sense for the most people here. Pellets are a solid second if you want a live flame without splitting anything. Wood still works, but you live with Front Range no burn days.
Foothills and mountain cabins
Above Evergreen, Conifer or Nederland, the math flips. Natural gas may not reach the property, so gas means a propane tank and a delivery truck that cannot always get up the road. Outages of a day or more are normal. Beetle kill pine is often free with a cutting permit. Here a wood stove is the primary heater and everything else is a convenience. A pellet stove at a cabin needs a generator plan or it is a decoration in January.
What Each Fuel Really Costs to Run
Fuel cost depends on where you live and what you already own.
- Wood. A cord of seasoned wood delivered along the Front Range typically runs in the low to mid hundreds of dollars, and a reasonably tight home might burn two to four cords a winter. Cut your own with a permit and the cost is mostly weekends.
- Pellets. Pellets come in 40 pound bags, fifty to a ton on a pallet. A stove on a moderate setting burns roughly one to two bags a day in cold weather, so a Colorado winter can run through two to four tons.
- Gas. Natural gas is the cheapest per unit of heat in most metro homes because the line is already there. Propane costs more per unit of heat plus tank rental and delivery. A gas stove at full output burns roughly 25,000 to 40,000 BTU per hour.
In short, wood is cheapest if your labor is free, natural gas is cheapest if it is already at the house, and pellets are predictable but rarely the cheapest.
Venting: Class A, Pellet Vent and Direct Vent, and What Each Does to Your Bill
Venting is where installation costs separate. The chimney system can cost as much as the stove.
Wood stove: Class A chimney
A wood stove needs a listed, insulated Class A chimney from the ceiling to a point above the roof that satisfies the 3-2-10 rule and the manufacturer's height minimum. Every length of pipe, support box, flashing and cap adds up. If you have an existing masonry chimney, a stainless liner sized to the stove outlet is often the smarter route, and our chimney lining service handles that work.
Pellet stove: pellet vent
Pellet exhaust is pushed by a fan, so the vent can run through an exterior wall with a short vertical rise, using listed pellet vent pipe with sealed joints. That short run is one reason pellet installs usually cost less than wood installs.
Gas stove: direct vent
A direct vent gas stove uses a coaxial pipe that pulls combustion air from outside and pushes exhaust out through the same assembly, terminating through a wall or the roof, so no room air is used. Our gas fireplace installation guide covers the gas line side, and our gas insert service is the right page if your unit is going into an existing fireplace.
Table 2. Venting systems for each stove type and how they shape the installation.
| Venting item | Wood (Class A) | Pellet (pellet vent) | Gas (direct vent) |
|---|---|---|---|
| Pipe type | Insulated double wall stainless, listed to UL 103 HT | Listed pellet vent, sealed joints | Coaxial pipe listed for the appliance |
| Height requirement | 3-2-10 rule plus manufacturer minimum, often 12 to 15 feet total | Manufacturer minimum, short | Manufacturer minimum, short |
| Relative install cost | Highest | Lower | Lowest to moderate, depending on the gas line |
| Altitude sensitivity | High, natural draft only | Low, fan driven | Low, but output derate applies |
Whatever you pick, the vent must match the appliance. A pellet stove cannot use a wood chimney without a liner and adapter, and a gas stove cannot share a flue with anything.
Hearth Pads and Clearances for All Three
Every freestanding stove sits on a noncombustible hearth pad and keeps a listed distance from walls, furniture and mantels. The stove's label wins over anything you read online, including this.
- Wood stoves need the largest pads and the longest clearances, commonly 12 to 18 inches or more to an unprotected wall, with the pad extending well in front of the door for ember protection.
- Pellet stoves usually allow much tighter clearances, sometimes a few inches at the rear, because most of the heat leaves through the front blower.
- Gas stoves have the smallest footprint and often the tightest clearances, and many need only a simple floor protector because there are no embers.
The mistake we see most is a wood stove too close to a log wall in a cabin, where the wood darkens and dries for years until it ignites. Single wall stovepipe needs 18 inches to combustibles unless shielded.
The Fuel Storage Question Nobody Asks Until October
A cord of wood is a stack four feet by four feet by eight feet. It needs to sit off the ground, covered on top, open to the wind, and within a short walk of the door in January. Wood against the house invites insects and is a wildfire concern.
A ton of pellets is a pallet roughly four feet square and four feet tall, and it must stay bone dry. Wet pellets swell, crumble and jam augers. A garage works. A carport that catches sideways monsoon rain does not.
Gas is easiest. Natural gas needs nothing. Propane needs a tank, commonly 250 to 500 gallons for a heating load, set at code distance from the house, with a delivery truck able to reach it in winter. In deep snow country, that last part is what fails.
Power Outages and Thin Air: How Each Stove Behaves When Colorado Pushes Back
When the power goes out
A wood stove does not care, which is why so many mountain families own one. A pellet stove stops and will not restart until power returns or you switch to a battery backup or generator. A gas stove with a standing pilot or millivolt valve usually keeps burning, but the blower stops, so less heat reaches the far side of the room. Gas stoves with electronic ignition need power or a battery module to light at all.
At altitude
Thin air means less oxygen per cubic foot and less lift in the chimney. A wood stove at 8,000 feet needs a taller chimney than the same stove at sea level, drier wood, and more patience on startup. Pellet stoves often have a high altitude setting or need the feed rate turned down so the fire does not choke on fuel. Gas stoves are typically derated by the manufacturer above a stated elevation, often starting near 2,000 feet, and some need a high altitude orifice.
Air Quality Rules Along the Front Range
The short version: Front Range no burn days restrict wood burning, pellet stoves are generally treated as cleaner burning devices, and gas stoves are not affected. Our gas vs wood fireplace guide explains how those rules tilt city buyers toward gas, and our Colorado chimney laws and regulations guide covers the county by county differences, including mountain limits on new solid fuel devices.
Daily Effort and Maintenance: What Your Week Looks Like
Ranked from most work to least.
- Wood stove. Haul wood in, load two to four times a day in real cold, adjust the air, empty ash every few days, and have the chimney swept at least once a season.
- Pellet stove. Fill the hopper daily or every other day, scrape the burn pot every day or two, empty the ash pan weekly, vacuum the heat exchanger monthly, and schedule a full teardown cleaning once a year.
- Gas stove. Turn it on. Have the burner, pilot, thermopile, gaskets and vent termination serviced once a year and clean the glass a couple of times a season.
A wood stove is a hobby and a gas stove is an appliance. Be honest about which one you want to live with.
The Honest Lifestyle Test: Answer These Before You Buy
Work through these in order.
- How often does your power go out, and how long do the longest outages last? More than a day at a time pushes you toward wood.
- Is natural gas at the house? If yes, gas is cheap to run and the default for most metro homes. If no, are you willing to own or rent a propane tank?
- Can a delivery truck reach your property in February? If not, propane and pellet deliveries both get harder.
- Do you have a dry, covered place for two to four tons of pellets or three or more cords of wood, close to the door?
- Are you willing to split, stack and carry wood every winter for the next ten years, not just this one?
- Does your county or HOA restrict solid fuel appliances? Check before you fall for a model.
- Is this the primary heat source or a backup? Primary heat needs output and outage resilience. Backup can favor convenience.
- What is your all in budget including the vent, hearth pad and annual service, not just the stove?
What Goes Wrong Most With Each Type
Wood stoves
Creosote from wet wood or smoldering burns, a warped baffle from overfiring, a door gasket that no longer seals so the stove runs away, cracked firebrick, and a cap screen plugged with soot that kills the draft.
Pellet stoves
Ash that chokes the burn pot and trips the flame sensor, an igniter that fails after a few seasons, fans that seize, and poor pellets that leave clinkers. Our pellet stove guide covers these failure points in depth.
Gas stoves
A pilot that will not stay lit because the thermopile is failing, a dirty burner that throws a lazy yellow flame and soots the glass, and a termination cap blocked by a bird or a snowdrift. Pilot trouble is the most common gas stove complaint, and our gas fireplace pilot light guide walks through it.
Whatever you own, an annual visit catches most of this before a cold night does. Our chimney inspection service covers wood and pellet venting, and the same visit can service a gas stove.
Resale, Insurance, and When a Stove Is the Wrong Answer
Insurers generally want to know about any solid fuel appliance, and some ask for proof of professional installation before they will write a policy. Gas stoves rarely raise a flag. An unpermitted wood stove can become a problem at claim time, so the install should be permitted and inspected. On resale, a clean install is a small plus in the mountains, while a sloppy one shows up in the buyer's inspection.
And sometimes the right call is not a freestanding stove at all.
- You have a working masonry fireplace and want heat from it. An insert uses the existing chimney with a liner and takes no floor space. Our gas vs wood fireplace guide is the better starting point.
- You want every room warm. A stove heats the room it sits in. For every bedroom at 68 degrees, a furnace or boiler with the stove as backup is the right design.
- The room is too small for the clearances. If the only spot puts the stove inches from a sofa or a doorway, pick a smaller gas unit or an insert.
Frequently Asked Questions
Which stove is cheapest to install in Colorado?
A gas stove with a short direct vent through an exterior wall and a gas line nearby is usually the least expensive install, with a through wall pellet stove close behind. A wood stove with a new Class A chimney is normally the most expensive.
Can a pellet stove run during a power outage?
Not on its own. The auger, exhaust fan and igniter all need electricity. A battery backup unit or a small generator keeps most pellet stoves running, and the vent should have some vertical rise so residual smoke drifts outdoors if the fan stops mid burn.
Are gas stoves derated at altitude?
Most manufacturers reduce the rated output above a stated elevation, often starting near 2,000 feet, and some require a high altitude orifice or a setting change.
Can I put a pellet stove on my old wood stove chimney?
Often yes, with a listed stainless liner sized for the pellet stove and the correct adapter. Pellet exhaust is cooler and more acidic than wood smoke, so it needs its own liner rather than an open masonry flue.
Which stove is best for a weekend mountain cabin?
For a cabin that sits empty all week and needs to be warm fast on Friday night, a gas stove on propane with a thermostat is the most convenient and can hold the cabin above freezing while you are away.
Do no burn days apply to pellet and gas stoves?
Front Range no burn restrictions target wood burning. Pellet stoves are generally classified as cleaner burning devices and gas stoves are not solid fuel appliances, so neither is normally restricted. Check the current advisory and your county rules to be sure.
