Short answer: Heating equipment is still one of the top causes of U.S. home fires. The U.S. Fire Administration reports that heating remained the second leading cause of home fires in 2021, and its 2023 national estimates put residential building heating fires at 27,900 fires, 115 deaths, 525 injuries and $488 million in dollar loss (USFA heating trends). Portable heaters are a small share of those fires but a large share of the deaths: for 2017–2019 they were only 3% of residential heating fires yet 41% of fatal heating fires (USFA). Chimney and flue fires dominate the confined-heating category. Home and renters policies usually treat fire and smoke as covered perils, but the claim still depends on what burned, your limits and deductibles, and whether anyone was hurt. This guide goes deeper on heating equipment than our holiday fires overview—without rehashing Christmas trees, candles or cooking.

What the official numbers say about heating fires
Overall heating-fire trend
USFA's residential building heating fire trends for 2014–2023 show a long decline: fires down 31%, deaths down 44%, injuries down 14%, and inflation-adjusted dollar loss down 17% (USFA). Even so, heating remains a major winter risk. For 2017–2019, heating was the second leading cause of residential building fires and about 9% of those fires (USFA Heating Fires topical report).
Confined chimney fires vs. room-and-contents fires
Most residential heating fires are "confined." USFA reports that 77% of residential heating fires in 2017–2019 were confined, and among those confined fires 49.43% were chimney or flue fires confined to the chimney or flue, while 27.16% were fuel-burner or boiler malfunctions confined to the equipment (USFA v21i10). Confined fires are coded as limited in severity; the nonconfined minority are the ones that more often destroy rooms and belongings.
For nonconfined residential heating fires, leading equipment involved in ignition included heating stoves (20%), unspecified heating equipment (17%), heaters including floor furnaces, wall heaters and baseboard heaters (15%), water heaters (12%) and furnaces (11%) (USFA v21i10). In 27% of nonconfined heating fires, the heat source was too close to combustibles.
Why portable heaters punch above their weight
USFA's portable-heater topical report (2017–2019) estimates an annual average of 1,100 portable heater fires in residential buildings, with 65 deaths, 150 injuries and $51 million in property loss (USFA v21i11). Key patterns from that report:
| Finding (USFA, 2017–2019) | Figure |
|---|---|
| Share of all residential heating fires | 3% |
| Share of fatal residential heating fires | 41% |
| Peak month | January (25% of portable-heater fires) |
| Leading factor contributing to ignition | Heat source too close to combustibles (48%) |
| Leading area of origin | Bedrooms (34%) |
| Leading item first ignited in bedroom fires | Bedding (16%) |
| Smoke alarms present (occupied residential) | 41% |
| Sprinklers / AES present (occupied residential) | 2% |
The Consumer Product Safety Commission separately estimated about 1,200 fires per year involving portable electric heaters for 2008–2010 and stresses that these are high-wattage appliances that can ignite curtains, beds, sofas, paper and clothing if left on and unattended.
Official prevention rules (space heaters, fireplaces, wood stoves, chimneys)
USFA, Ready.gov and CPSC publish nearly the same checklist. Treat these as the baseline before any claim conversation.
Portable / space heaters
From the USFA heating fire safety handout, Ready.gov heating materials and CPSC Publication 098:
- Keep anything that can burn (bedding, clothing, curtains, furniture, paper) at least 3 feet from the heater—front, sides and rear.
- Use a heater with an automatic tip-over shut-off; CPSC has long recommended thermostat control plus tip-over shut-off for electric heaters.
- Turn the heater off when you leave the room or go to bed. Never leave it operating while unattended or while sleeping.
- Plug portable heaters directly into a wall outlet. Do not use an extension cord or power strip.
- Use only heaters from a recognized testing laboratory (NRTL mark). Check CPSC heater safety / SaferProducts recall checks for recalls before you buy or after you find an old unit in storage.
- Place the heater on a stable, level, hard surface—not on rugs or soft bedding.
- Never run the cord under rugs or carpeting.
- Keep electric heaters away from water; never touch one if you are wet. Extra caution in bathrooms.
- Inspect the heater, cord and plug before each season; if the plug, outlet or faceplate feels hot in use, stop and call a qualified electrician.
USFA's heating page also says: never use an oven to heat your home (USFA). CPSC warns that open ovens used for heat can emit carbon monoxide. For CO alarms and fuel-fired heaters, see our carbon monoxide alarms guide.
Fireplaces
USFA's handout:
- Keep a glass or metal screen in front of the fireplace to stop embers and sparks.
- Do not burn paper.
- Put the fire out before you sleep or leave.
- Put ashes in a metal container with a lid, outside, at least 10 feet from the home.
Wood stoves and chimneys
USFA:
- Keep the wood stove 3 feet from anything that can burn.
- Do not burn paper in the stove.
- Put the fire out before sleep or leaving.
- Have the chimney inspected and cleaned each year by a professional.
The same annual professional cleaning and inspection message appears on USFA's heating page for heating equipment and chimneys generally, and for furnaces: inspect each year and keep combustibles away (USFA).
Kerosene heaters
USFA: use only lab-tested units; tip-over shut-off; refuel a cooled heater outdoors.
How a heating-equipment fire claim usually breaks down
Most homeowners and renters forms treat fire and smoke as covered causes of loss for the dwelling (or, for renters, personal property) and for liability if someone is injured. The NAIC lists fire among the typical covered perils and describes the standard parts of a homeowners policy: dwelling, other structures, personal property, loss of use, personal liability and medical payments. Exact limits, deductibles and exclusions are in your contract.
A typical heating-fire claim may involve several coverages at once:
- Dwelling / building — structural repair after a nonconfined fire or smoke/water damage from firefighting.
- Personal property / contents — furniture, clothing, electronics damaged by fire, smoke or water. Category sublimits can apply to certain valuables.
- Additional living expenses (loss of use) — hotel and related costs if the home is uninhabitable after a covered fire. See additional living expenses coverage.
- Liability / medical payments — if a guest is burned or a fire spreads to a neighbor's property and you are legally responsible.
- Ordinance or law / code upgrades — sometimes needed when a chimney, furnace or electrical system must be rebuilt to current code; this is often limited or optional.
Renters: your policy covers your belongings and liability, not the building. Landlords: a landlord policy covers the structure; tenants need their own renters insurance.
Claim checklist after a heater, fireplace or chimney fire
Indiana's winter-weather consumer alert and Texas's disaster-claim FAQ give the same order of operations that applies after any covered fire or storm loss (Indiana DOI; TDI FAQ):
- Get people out and call 911 if the fire is active. Do not re-enter until firefighters say it is safe.
- Notify your insurer or agent as soon as you can with your policy number.
- Photograph and video damage before cleanup when it is safe—rooms of origin, the heater or fireplace, smoke paths, water from firefighting.
- Make only temporary repairs needed to prevent more damage (board openings, temporary weather protection). Texas says it is generally OK to make temporary repairs and that the policy should pay for materials and labor used for those repairs—but take pictures first and do not make permanent repairs until you have talked to the company (TDI FAQ).
- Keep every receipt for emergency board-up, cleaning, hotel stays and temporary heat.
- Save the failed equipment if the insurer or fire investigator wants to inspect it (space heater, damaged flue section, stove). Do not discard until they say so.
- Ask about living expenses if you cannot stay in the home.
- Document prevention you had in place: tip-over shut-off models, chimney-sweep invoices, smoke-alarm and CO-alarm maintenance. That does not create coverage by itself, but it answers adjuster questions about use and maintenance.
Texas also publishes claim-handling timelines that apply to insurers in that state (acknowledge, decide, pay) in its insurance claims tips. Other states set their own clocks; see home insurance claim and lawsuit deadlines by state.

If you and the insurer disagree
Ask for the denial or underpayment reason in writing and the policy language cited. Indiana directs consumers with settlement disputes to their state insurance department (Indiana DOI); Texas's help line is 800-252-3439. Some households hire a licensed public adjuster; rules differ by state—see public adjuster rules by state. Find your regulator through our state insurance rules hub.
Frequently asked questions
Do homeowners policies usually cover a fire started by a space heater?
Fire and smoke are typically listed perils on homeowners and renters forms (NAIC). Coverage still depends on your limits, deductible, any exclusions, and the facts of the loss. Read your policy.
Why do regulators talk so much about the "3-foot" rule?
Because proximity to combustibles is the leading ignition factor in the data. USFA found the heat source too close to combustibles in 48% of portable-heater fires and in 27% of nonconfined heating fires (USFA v21i11; v21i10).
Are chimney fires "real" insurance claims if the fire stayed in the flue?
Often they are still reportable losses—especially if the chimney, liner or surrounding structure is damaged. USFA classifies many chimney/flue events as confined fires, which tend to have lower flame damage, but repair costs and smoke issues can still be significant. Report promptly and let the insurer inspect.
Can I use a portable heater overnight?
USFA and CPSC both say to turn space heaters off when you go to bed or leave the room (USFA handout; CPSC Pub 098). Portable heaters also account for a disproportionate share of fatal heating fires.
What should I keep after a heating fire to support the claim?
Photos and video before cleanup, the damaged heater or flue parts if requested, chimney-service records, smoke/CO alarm evidence, a contents inventory, and receipts for temporary repairs and living expenses. Texas and Indiana both emphasize photos first and receipts for temporary work (TDI; Indiana DOI).
