The best kerosene heater for heating a room in a power outage is the Sengoku HeatMate HMN-110, a 10,000 BTU radiant heater that lights from batteries, needs no electricity and has a tip-over switch. It is the one wick heater a hands-on tester ran (Bob Vila) and the one named in more of the roundups we read than any other. For a large room or an open floor, the Sengoku HeatMate HMC-23K, a convection heater rated at 23,000 BTU in its manual, with a 1.9 gallon tank and a tip-over switch, is named by three of the roundups we read. If you run either indoors, follow the Consumer Product Safety Commission's guidance: 1-K kerosene only, refuel outdoors with the heater off and cool, leave the door between the room and the rest of the house open, and never run it in a room where someone is sleeping. In Massachusetts, state law bans using or selling one, and in New York City using one for space heating is illegal.

That last point is not small print. The University of Alaska Fairbanks Cooperative Extension classes every portable kerosene heater as unvented, and the CPSC says kerosene heaters give off low levels of pollutants while they burn, carbon monoxide and nitrogen dioxide among them. The CPSC also wants a battery-operated or battery-backup carbon monoxide alarm for every level of the home, and the makers' manuals are part of the purchase: World Marketing, which makes pick 3, says its indoor kerosene heaters are for supplemental heat, not a home's main source of heat.

Start here: which kerosene heater for you

• One room during a power outage: the Sengoku HeatMate HMN-110 (pick 1), the radiant heater a tester ran and the roundups name most.
• A large room or open floor of about 575 square feet or more: the Sengoku HeatMate HMC-23K (pick 2), a convection heater that sends heat in every direction and needs no power. Below about 575 square feet at an 8 foot ceiling, its manual says to keep the doors to the next rooms open or a window open at least 1 inch (see the room-size rule). The Comfort Glow KW-24J (pick 3) does the same job from a second maker, whose manual says never to run it in a room under about 595 square feet.
• The heater that stretches a can of kerosene furthest: of the heaters we link, pick 1, at about 62 hours per 5 gallon can by its manual's maximum rate. The Kero World 10,000 BTU radiant heater and the Dyna-Glo RMC-55R7B burn a little less (0.07 gallons an hour against pick 1's 0.08), but both were out of stock on Amazon on October 12, 2026.
• A garage, barn or workshop with fresh air coming in (its manual: never in living or sleeping areas): the Dyna-Glo Workhorse KFA50WH forced air heater (pick 4). It needs a 120 volt outlet, so it is no help in an outage without a generator.
• Every buyer: a battery carbon monoxide alarm for the house, such as the Kidde COB (pick 5), because none of the heater pages or manuals we read lists a carbon monoxide sensor. World Marketing's manuals also say never to run a heater unless a working fire extinguisher and a smoke detector are close by.
• A greenhouse: UMass Extension warns that the gases and moisture from an unvented kerosene or propane heater can injure plants; see our best greenhouse heater guide.

Best kerosene heaters at a glance

The best kerosene heaters, by room and job

1. Sengoku HeatMate HMN-110 10,000 BTU Radiant Heater: best overall

The HMN-110 is a 10,000 BTU radiant heater that Sengoku says warms a room of about 400 square feet. Its 1.2 gallon cartridge tank gives 14 hours on Sengoku's product page and 14.5 to 16 hours in its manual, at a maximum fuel use of 0.08 gallons an hour. Sengoku lists an automatic safety shut off and a tip-over switch, push-button battery ignition, a UL listing in the manual, and a 2 year limited warranty, and marks it for indoor and outdoor use.

Why it is the pick: it is the one wick heater we found that a tester actually ran. Bob Vila ran it on a cold day in an open garage, got warm enough that the tester shed layers, found it quiet enough to lose track of it running, and notes that a tube and pump for filling the tank come in the box. Five research roundups also name it, more than any other kerosene heater we looked at. A radiant heater throws heat forward from a reflector, which is why it suits one room or a spot you are working in. Its manual sets the rules: use the enclosed siphon and fill the tank outdoors, never remove the cartridge tank while the heater is burning or still hot, keep children, clothing and furniture at least 36 inches from its top and front, never leave it unattended, and turn it off before going to bed. It also tells anyone with breathing problems to see a doctor before using it, and to wait 60 minutes after the first fill so the wick can soak before lighting.

Where it loses: Bob Vila's cons are safety cons: it gets very hot, it is a poor fit where there are children or pets, and it needs good ventilation indoors. Primal Survivor passes on owners' reports that a tank ran dry in about 6 hours even turned down, and says a wick set too low brings bad odors. At 10,000 BTU it will not heat a large open floor, and in a room under about 250 square feet at an 8 foot ceiling its manual says to keep the door to the next room or a window open (see the sizing table).

2. Sengoku HeatMate HMC-23K 23,000 BTU Convection Heater: best for a large room or open floor

The HMC-23K is Sengoku's HeatMate convection heater. Its manual rates it at a maximum of 23,000 BTU an hour, while Sengoku's product page says 23,500 BTU and about 1,000 square feet. Its 1.9 gallon tank runs 9 to 12 hours per the manual (12 hours on the product page), at a maximum fuel use of 0.167 gallons an hour. Sengoku lists an automatic safety shut off and a tip-over switch, push-button battery ignition with no matches or electricity needed, a siphon pump and batteries in the box, and a 2 year limited warranty, marks it for indoor and outdoor use, and its manual gives a UL listing.

Why it is the pick: a convection heater draws air in and sends warm air out in every direction, the shape for the middle of a large room or an open floor, and the HMC-23K does it with no plug. Three research roundups name it (HeavyDutyPR, Eye and Pen and Mossy Oak), and Sengoku covers it in the same owner's manual as its KeroHeat CV-23K, the top pick at Heater Advisor (see Also considered). It comes from the same maker as pick 1. At this output the makers' air rule matters: below about 575 square feet at an 8 foot ceiling, its manual says to keep the doors to the next rooms open or a window open at least 1 inch, and not to use it "in a bathroom or any other small room with the door closed" (see the smallest-room column). Its manual also calls for 1-K kerosene only, clear or red dyed, filling the tank outdoors and never while the heater is running or still hot, keeping children, clothing and furniture at least 36 inches from its top and front, and turning it off before going to bed or going out. It tells anyone with breathing problems to see a doctor before using it, and to light it outdoors the first time so the oils and waxes left from manufacturing burn off.

Where it loses: no tester has run it, and Sengoku's own figures disagree: 23,500 BTU on the product page against 23,000 in the manual, and the manual's spec table and parts list give two C cells for the igniter, while its lighting instructions and the product page say two D batteries. Its tank is built in, so its manual has you take the whole heater outdoors to fill it by siphon, where pick 1 sends out only its lift-out tank. The roundups' cons are smell and build: HeavyDutyPR says some units smell a little at start-up and shutdown, and Eye and Pen passes on owner complaints about build quality and odor. Unlike pick 3's product page, Sengoku's prints no state rules, so check where they are banned before you buy.

3. Comfort Glow KW-24J 23,800 BTU Convection Heater: runner-up for a large room

The KW-24J is World Marketing of America's current round convection heater, sold under the Kero World and Comfort Glow names. World Marketing rates it at 23,800 BTU for as much as 1,000 square feet. Its 1.9 gallon tank runs about 9 to 12 hours per the manual, which lists a maximum fuel use of 0.167 gallons an hour. Two C cell batteries, included, power a push-to-start igniter, and the product page says no electricity is required. The manual describes an automatic safety shut-off device that shuts the heater off if it is jarred or tipped over while running. The maker lists it as UL listed with a 2-year warranty, 26.75 inches tall.

Why it is the pick: it does pick 2's job from a second maker, with no plug, a maker rating of as much as 1,000 square feet and the highest maker output figure of the wick heaters here. Of the two, its manual is the stricter on room size. At this output the makers' air rule matters: World Marketing's manual rules out a bathroom, and any small room that gives the heater less than 200 cubic feet of air for each 1,000 BTU an hour of its rating, which for this heater works out to about 595 square feet at an 8 foot ceiling (see the smallest-room column), and that rules out most single rooms: it is for a large or open space. Its manual's numbered rules include never operating the heater unless a working fire extinguisher and a smoke detector are close by, 1-K kerosene only, filling the tank outdoors, letting the heater cool at least 15 minutes before moving it or refueling, keeping it at least 36 inches from drapes and furniture, and never leaving it running when you go to bed.

Where it loses: no tester has run it, and the roundups we read name its older sibling, the KW-24G, less often than the Sengoku and Dyna-Glo heaters, which is why it sits behind pick 2. World Marketing's own pages disagree on where it can be used: the product page calls it an indoor/outdoor heater, while the maker's pre-purchase page says its indoor kerosene heaters are for indoor use only and not outdoors. Its manual has you carry the whole heater outdoors and fill it by siphon, where pick 1 sends out only its lift-out tank. The product page also prints two state rules, which are about the place, not this heater: California prohibits its use in any dwelling, house or unit, and its sale is prohibited in Massachusetts (see where they are banned).

4. Dyna-Glo Workhorse KFA50WH 50,000 BTU Forced Air Heater: for a garage or workshop

A forced air, or torpedo, heater uses an electric fan to blow its heat out. The KFA50WH is rated at 50,000 BTU on a 120 volt supply, with a 5 gallon tank; its manual's spec table gives a fuel use of 0.38 gallons an hour, about 13 hours a tank, and a retailer listing says 1,200 square feet and 14 hours. The manual allows 1-K kerosene or No. 1 diesel or fuel oil, and says it complies with UL733.

Why it is the pick: Bob Vila's best kerosene heater was Dyna-Glo's KFA50DGD, a 50,000 BTU forced air heater with the same 1,200 square foot rating and 5 gallon tank on Dyna-Glo's page. In an uninsulated 800 square foot shop at 50F, Bob Vila found it out-heated the shop's wood stove on its own. On October 12, 2026 Amazon showed that model only in limited stock, so it is not a pick; the Workhorse KFA50WH is the Dyna-Glo at the same output that Amazon showed in stock, and Dyna-Glo's own figures give both the same dimensions and the same 26.9 pound weight. We have not confirmed the two share their internals, so treat Bob Vila's result as evidence for the design, not a test of this unit.

Where it loses: its manual is blunt: never use it in living or sleeping areas, use it only in well ventilated areas, and give it fresh outside air through an opening of at least 3 square feet per 100,000 BTU an hour of rating, which works out to 1.5 square feet for this one. It asks for 8 feet of clearance from combustibles at the outlet and 4 feet at the sides, top and rear. It also says to fill the tank outdoors, never to transport the heater with fuel in its tank, and to keep children and animals away. For Massachusetts, the manual says state law prohibits using it in any building "used in whole or in part for human habitation" and that any use there needs a local fire department permit; in New York City it is for construction sites only under an FDNY certificate of approval. Bob Vila's cons on the sibling apply: one heat setting, loud enough to disrupt a conversation, and it cannot run without electricity. Kidde's guide says not to install its alarm (pick 5) in a garage, so that alarm is for the house, not the shop. For electric and propane garage options, see our best garage heater guide.

5. Kidde COB AA Battery Carbon Monoxide Alarm: best alarm for the house

A battery-operated carbon monoxide alarm that runs on two AA batteries, included, so it keeps working in the power outage you bought the heater for, and it can sit on a table or mount on a wall. Kidde's data sheet says it meets UL 2034 and sounds at 85 dB at 10 feet, and that it warns you when it is due for replacement, 10 years after first power up.

Why it is the pick: none of the heater pages or manuals we read lists a carbon monoxide sensor, and the CPSC tells you to put a CO alarm that meets UL 2034, battery-operated or battery-backed, outside sleeping areas and on each level of the home, and not above fuel-burning appliances. Kidde's user guide recommends one on every floor, above all a floor with a fuel-burning appliance, placed outside the bedrooms, and rules out garages, spots within 6 feet of a heating or cooking appliance, and anywhere that drops below 40F. Kidde's papers agree on its life: the data sheet and the user guide both say to replace it after ten years, and both give a ten year limited warranty.

Where it loses: it shows no CO reading; Kidde's display models, such as the COBD, do. Kidde's page says its AA batteries need changing once a year under normal use, where Kidde's sealed 10 year battery model, the COB10, needs no battery changes. Kidde's guide also warns that an alarm outside the bedroom or on another floor may not wake a sound sleeper, and says it is not for an RV or a boat. The CPSC's caution holds for any alarm: it is added protection, no substitute for using the heater properly.

How we chose these

We compared each heater's Amazon listing with the maker's product page and owner's manual, then read what independent reviewers reported. Hands-on testing of kerosene heaters is thin. Bob Vila ran two kerosene heaters in its non-electric heater test, the Sengoku HeatMate and a Dyna-Glo 50,000 BTU forced air heater, and Car and Driver ran one kerosene unit, a Remington 80,000 BTU, in its garage heater test. The rest of the roundups on this search, such as Primal Survivor and HeavyDutyPR, compare listings and owner reports without testing of their own, so we used them to count which models the roundups name and for the cons owners report, not as test evidence.

That is why the tested Sengoku leads. For a large room, we counted the convection heaters the roundups name and checked each against its maker's page and manual. Sengoku covers its HeatMate HMC-23K, KeroHeat CV-23K and KeroHeat CV-23K H in one owner's manual, with the same figures on all three product pages, and counting all three names, four of the roundups we read list that heater, tied with the Dyna-Glo WK24BK, which no longer returned a product on Amazon on October 12, 2026. We link the HMC-23K, pick 2, because three of those roundups name it, and Sengoku's page and manual agree with its Amazon listing on the 1.9 gallon tank, a run time of up to 12 hours and the tip-over switch. The Comfort Glow KW-24J, pick 3, is the same class from a second maker with its own current page and manual; the roundups name only its older sibling (see Also considered for the rest). For safety we used only the CPSC, the EPA, the US Fire Administration, NFPA, state fire codes, a land-grant extension service (the University of Alaska Fairbanks) and the makers' manuals, and we say which one each rule comes from. Every numbered pick was in stock on Amazon on October 12, 2026.

Also considered: models that missed the list and why

Dyna-Glo RMC-95C6B. A 23,000 BTU round convection heater with a 1.9 gallon tank, about 8 to 12 hours a tank and the same 0.167 gallons an hour as pick 2, per Dyna-Glo's manual, which also describes a tip-over shutoff. HVAC Life Hack and Jen Reviews list it. It missed because Amazon showed it in limited stock on October 12, 2026, and Dyna-Glo no longer has a product page for it: its current heater of this size is the WK24BK below.

Dyna-Glo WK24BK. Dyna-Glo's current 23,800 BTU convection heater and Primal Survivor's top pick, named in four roundups. The Amazon listing those roundups link no longer returned a product on October 12, 2026, so we do not link it. Primal Survivor's caution is worth reading if you find one: it reports as little as 4 to 5 hours a tank on high.

Sengoku KeroHeat CV-23K and CV-23K H. The KeroHeat names for pick 2's heater: Sengoku covers them in pick 2's owner's manual, and their product pages give the same figures as pick 2's: 23,500 BTU (23,000 in the manual), about 1,000 square feet, a 1.9 gallon tank for 12 hours and a tip-over switch. The CV-23K is Heater Advisor's top pick and is named by HeavyDutyPR and Eye and Pen; Mossy Oak names the black CV-23K H. On October 12, 2026, Amazon listed the white single CV-23K as unavailable and had it in stock as a 2-pack, and the black CV-23K H was in stock as a single heater. We link the HMC-23K instead because it has the same manual and figures and three of the roundups name its listing, against one for the CV-23K H.

Dyna-Glo WK95C8. A 23,800 BTU convection heater by its Amazon title (Lowe's lists a Master Forge WK95C8M with the same 23,800 BTU rating) that HeavyDutyPR calls its best overall indoor heater and Eye and Pen lists. Amazon showed it in stock on October 12, 2026, but it missed: the listing's feature list says 23,000 BTU an hour against the 23,800 in its title, Dyna-Glo's own page, for a WK95C8C, carries the same two figures and gives both 8 to 12 hours and up to 11 hours a tank, and the manual link on that page returned an error, so we could not check its figures against a manual. Picks 2 and 3 do the same job with manuals we could read.

Sengoku KeroHeat CTN-110. Eye and Pen's top choice and a Jen Reviews pick, a 10,000 BTU radiant heater that shares its manual with pick 1. Amazon showed it only in limited stock on October 12, 2026, so we do not link it; pick 1 does the same job under the same manual.

Kero World 10,000 BTU radiant heater. World Marketing's radiant heater with a glass burner, the KW-11 family (the maker's current model is the KW-11G, and its manual is the KW-11F). Its 1.0 gallon lift-out tank runs about 11 to 14 hours per the manual, at 0.07 gallons an hour, the lowest maximum fuel use in any manual we read: about 71 hours per 5 gallon can at its maximum rate, against about 62 for pick 1. It was out of stock on Amazon on October 12, 2026, so we do not link it.

Dyna-Glo RMC-55R7B. A 10,000 BTU radiant heater rated for 500 square feet on its listing and named in four roundups. Its manual gives the same 0.07 gallons an hour and 1.0 gallon cartridge tank as the Kero World radiant above. It was out of stock on Amazon on October 12, 2026. Primal Survivor says its wick is hard to adjust, which can bring odors.

Dura Heat DH1051. A small 10,500 BTU convection heater whose listing says it runs up to 15 hours on 1.1 gallons. One research roundup names it. It missed because World Marketing's current indoor kerosene catalog no longer lists it, so there is no maker page to check its claims against; the Comfort Glow KW-24J, pick 3, comes from the same maker with a current page and manual.

Remington 80,000 BTU Kerosene/Diesel Heater. Car and Driver's best heater for shops and barns after testing: in 15 minutes it took the magazine's garage from 53F to 61F with the door slightly open on a 38F day. Car and Driver also describes visible flame from the heater, a smell like standing beside a diesel truck, a lot of weight and no way to turn the output down, and says to keep anything 10 feet from its flame. It missed because Car and Driver itself files it as a workshop or barn heater more than a garage heater, and pick 4 covers the workshop job at 50,000 BTU.

Mr. Heater 75,000 BTU Forced Air Kerosene Heater. The MH75KTR, named by Primal Survivor and Jen Reviews: 75,000 BTU, a 6 gallon tank, 0.55 gallons an hour and a 115 volt supply per the Mr. Heater manual, which marks it "not for home or recreational vehicle use." It missed because its Amazon listing promises six-function LED diagnostics while the manual says this model has no diagnostic board or flashing LED indicator, and Mr. Heater's product page for it now returns an error.

Dyna-Glo KFA50DGD. Bob Vila's tested best kerosene heater (see pick 4). Amazon showed it only in limited stock on October 12, 2026, so we do not link it.

First Alert CO400. A battery carbon monoxide alarm that First Alert lists to UL 2034, at 85 dB at 10 feet. It is a fine alternative to pick 5. It missed because First Alert's own documents disagree on its battery (9 volt on the product page, two AA in the manual) and warranty.

Kidde Nighthawk KN-COB-B-LP. A battery carbon monoxide alarm on three AA batteries that Kidde's datasheet says meets UL2034 and sounds at 85 dB at 10 feet. It missed because Amazon listed it with a later ship date, not in stock, on October 12, 2026, and Kidde's own papers disagree on how long it lasts: the datasheet and the Amazon listing give seven years of operation, while the user guide says to replace it ten years after first power up.

Two-in-one kerosene heater and stoves (VEVOR 9,000 BTU, AHUAWA 10,000 BTU, LINWIN). These squat heaters with a cooking top fill the Amazon search results, and several roundups list them. We do not link them: HeavyDutyPR says the LINWIN lacks an automatic tip-over shutoff, and the VEVOR and AHUAWA listings we checked mention a safety grill and an anti-tip base but no automatic shutoff. The US Fire Administration says a kerosene heater should have an automatic shut-off that turns it off if it tips over. The AHUAWA listing even suggests a bedroom, an RV or a tent, while the CPSC says: "Never operate unvented fuel-burning appliances in any room where people are sleeping."

What size kerosene heater do you need, and how much kerosene does it burn?

The makers give a heating area, but the number that decides whether a heater fits a room is in the manuals. The Kero World, Dura Heat, Dyna-Glo and Sengoku manuals all print an air rule based on 200 cubic feet of room air for each 1,000 BTU an hour of heater rating, and some add a stricter rule on top of it. The Sengoku and Dyna-Glo manuals say that below it you should leave the doors to the adjoining rooms open, or open a window to the outside by at least 1 inch. World Marketing's manuals for pick 3 and the Kero World radiant, and the Dura Heat manual, print that same door-or-window paragraph and then go further in their numbered safety rules: never in a bathroom, and never in any small room that gives the heater less than 200 cubic feet of air space for each 1,000 BTU an hour of its rating. The table turns that rule into floor area at an 8 foot ceiling, and turns each manual's maximum fuel use into hours per 5 gallon can. Both computed columns are our arithmetic; the inputs are the makers' figures.

Three things to take from it. First, the air rule bites early: in an ordinary 12 by 15 foot room (180 square feet), every wick heater in this table is under the line. The Sengoku manuals for picks 1 and 2 and the Dyna-Glo manuals want a door to the next room or a window open; World Marketing's manuals, pick 3's among them, print that same rule in their warning blocks, but their numbered rules say not to run the heater in a room that small. The CPSC goes further for every kerosene heater and says to run it with the door between the room and the rest of the house open. Second, the hours are at the maximum setting, and real runs can be shorter: Primal Survivor passes on owner reports of a pick 1 tank running dry in about 6 hours even turned down, and says a Dyna-Glo convection heater may give only 4 to 5 hours a tank at maximum, so plan on more fuel than the math says. Third, a 10,000 BTU radiant heater stretches a can more than twice as far as a 23,000 BTU class heater, which matters in a long outage if you only need to keep one room livable.

What is the best kerosene heater for indoor use?

For one room, the Sengoku HeatMate HMN-110 (pick 1), and for a large room or an open floor, the Sengoku HeatMate HMC-23K (pick 2). Both are wick heaters that light from batteries and burn with no electricity, both listings name an automatic shut-off and a tip-over switch, and pick 1 is the one wick heater we found that a hands-on tester ran. The Comfort Glow KW-24J (pick 3) does pick 2's job from a second maker. The forced air heater, pick 4, is not one for the house: its manual says never to use it in living or sleeping areas.

Choose by the room as well as by the heat. Each wick heater's manual sets an air rule (see the sizing section above), and the more heat a heater puts out, the larger the room it needs. The table lines up what the three wick heaters' listings and manuals say about indoor use.

The rules that come with any of them are in the next section: the CPSC's (the door between the room and the rest of the house open, never in a room where someone is sleeping, 1-K kerosene only, and refueling outdoors with the heater off and cool), and a battery carbon monoxide alarm such as the Kidde COB (pick 5), which runs on two AA batteries and so keeps working in an outage. Check where you live before you buy, too: in Massachusetts, state law bans using or selling one, and in New York City using one for space heating is illegal (see where kerosene heaters are banned, below).

Is it safe to use a kerosene heater indoors?

The public sources set conditions, and some advise against it. The University of Alaska Fairbanks Cooperative Extension does not recommend unvented kerosene or propane heaters for use inside the home. Where you do use one, these are the rules the CPSC, the EPA, the US Fire Administration, NFPA and the makers' manuals give, and your local code comes first:

• Ventilate. The CPSC says to run the heater with the door between the room and the rest of the house open, and to open an outside window about one inch if you must close the door or your home is new and tight or has been winterized. The EPA advises opening a door into the rest of the house, and a window a little, whenever a space heater is running.
• Never while sleeping, never unattended. The CPSC says: "Never operate unvented fuel-burning appliances in any room where people are sleeping." The US Fire Administration says: "Turn heaters off when you go to bed or leave the room." Every wick heater manual we read says the same. The forced air manuals we read keep their heaters out of the home instead: Dyna-Glo's says never to use its heater in living or sleeping areas, and Mr. Heater's says it is not for home use.
• Three feet of clearance. The US Fire Administration says anything that can burn, bedding, clothing and curtains included, belongs at least 3 feet from the heater, and the manuals say 36 inches. NFPA recommends a kid-free zone of three feet around space heaters.
• A carbon monoxide alarm. See pick 5 for the CPSC's and Kidde's placement rules. The CPSC's carbon monoxide fact sheet counts 33 CO deaths tied to portable heaters in 2020, second only to generators among the product categories it lists.
• A fire extinguisher and smoke alarms. World Marketing's manuals say never to operate the heater unless a working fire extinguisher and a smoke detector are close by, the CPSC says to "install smoke alarms on every level of the home, outside sleeping areas, and inside bedrooms," and Ohio's fire code requires a 2-A, 20-B:C extinguisher within 25 feet of an operating kerosene heater.
• If it flares up. The CPSC says not to move or carry the heater, to use its manual shut-off switch if it has one, and if that does not put out the fire, to "leave the house immediately, and call the fire department." The CPSC's sample label adds three don'ts: do not move the heater, do not try to smother the fire, and do not put water on it. The manuals add their own steps and they differ from the CPSC's (Sengoku's HMN-110 manual says to use a fire extinguisher if the shut off button does not put the flame out), so read yours before the first lighting.
• Watch the flame. The EPA says a persistent yellow-tipped flame generally means the heater is out of adjustment and putting out more pollution. Sengoku's manual says never to run the wick below its minimum setting to save fuel, because of the risk of fire and carbon monoxide.
• Not in small rooms. The manuals rule out a bathroom or other small room with its door shut, and World Marketing's numbered rules say never in a small room below the 200 cubic foot rule. The CPSC adds that exposure to "low levels of these pollutants may be harmful, especially to individuals with chronic respiratory or circulatory health problems."

The HMN-110, HMC-23K and KW-24J manuals tell anyone with breathing, respiratory or circulatory problems to see a doctor before using the heater. If that rules kerosene out, or you cannot keep a door and window open, backup power for an electric heater is the other route; our inverter generator guide and portable power station guide cover it.

Where are kerosene heaters banned or restricted?

Rules vary by state and city, so check your local fire code before you buy. What the sources we saved actually say:

• Massachusetts: state law says "no person shall use, allow to be used, sell or offer for sale any unvented liquid fired space heater," and the state Department of Fire Services says: "It is illegal to sell or use them in Massachusetts."
• New York City: the FDNY says "the use of kerosene or propane space heaters is strictly prohibited and illegal in New York City," and the city fire code bars using kerosene and other portable space heaters indoors.
• California: World Marketing's product pages, pick 3's among them, say the state prohibits their use in any dwelling, house or unit. The other makers' pages we saved, Sengoku's for picks 1 and 2 among them, do not address California, so check the state rule before buying any kerosene heater there.
• Houses, apartments, schools and assembly buildings under the International Fire Code: the International Fire Code, which Ohio's and Oregon's state fire codes follow, prohibits portable unvented fuel-fired heaters in assembly, school, institutional and residential occupancies, a list that includes houses. The one exception is that a heater listed and labeled to UL 647 may be used in a one- or two-family home, if it is run and maintained per the maker's instructions. It also bars unvented heaters from sleeping rooms, bathrooms, toilet rooms and storage closets.
• Other state rules: Ohio adopts that same prohibition and exception, and adds rules including an automatic tip-over device, 1-K fuel only, no refueling indoors, and a noncombustible mat or base reaching at least 3 feet out from the heater on every side; Maryland permits them only if they meet UL 647 and with the property owner's written consent in single-family homes; Illinois prohibits them in listed building types, including common areas of apartment buildings.

That is why one gap matters: the fire codes speak of UL 647, but none of the wick heater makers' pages or manuals we saved names the standard. They say only that they are UL listed. If your code requires UL 647, ask the maker or check the heater's label before you rely on it.

What kerosene should you use, and where do you buy it?

1-K only. The CPSC says: "Use only water-clear 1-K grade kerosene." It warns against gasoline, noting that "even small amounts of gasoline or other volatile fuels or solvents mixed with kerosene can substantially increase the risk of a fire or an explosion." Grades other than 1-K can release more pollutants into your home, and because grades look alike, the CPSC says the dealer should certify it is 1-K. The Ohio fire code, which adopts the ASTM D3699 fuel standard, describes 1-K as a low-sulfur grade suitable for unvented heaters and 2-K as a higher-sulfur grade for vented or flue-connected heaters.

Red is allowed, if it is 1-K. World Marketing says kerosene not taxed for road use must be dyed red, and that red kerosene sold as K-1 can go in your heater, though it recommends clear K-1 when available because contamination is much easier to see in clear kerosene. Sengoku's and Dyna-Glo's manuals both allow red-dyed 1-K.

Where to buy it. World Marketing says convenience stores and service stations are where K-1 kerosene is most often sold, and that buying small amounts keeps the fuel fresh. Its KW-24J manual says kerosene is best bought pre-packaged in a blue metal or plastic container, and that bulk buyers should know their dealer.

A blue can, and no leftovers. The CPSC notes kerosene containers are usually blue and gasoline containers red; Toyotomi's manual says never to use a red can for kerosene, and names a gasoline can mistaken for kerosene at refueling time as one major cause of fires in kerosene heaters. On leftovers, World Marketing recommends storing K-1 for one to six months at most and never from one season to the next, and the Dura Heat and Dyna-Glo manuals also rule out kerosene kept over from the season before. A Justrite Type I kerosene safety can is blue galvanized steel with a flame arrester and a self-closing lid, per its listing, and a hand TERA PUMP TRDP14 siphon pump, which its maker lists for kerosene, moves fuel from can to tank if your heater did not come with one.

Check bottled kerosene against recalls. In 2026 the CPSC announced recalls of pre-filled 1-K kerosene containers from Sunnyside and Alliance Chemical, both sold on Amazon, because the containers break the mandatory federal safety rules for portable fuel containers. If you have bottled 1-K kerosene on the shelf, check the CPSC recall pages before using it: the Alliance Chemical bottles were sold from January 2023 through March 2026, and the Sunnyside gallon bottles are batch 26082, sold May through July 2026.

Convection, radiant or forced air kerosene heater?

Convection heaters such as picks 2 and 3 heat the air and send it out in every direction, so they suit the middle of a large room. They are the 23,000 BTU class and burn the most fuel of the wick heaters. Radiant heaters such as pick 1 use a reflector to throw heat forward, suit a smaller room or a spot you are sitting in, and run longer on a tank. Both are wick heaters that light from batteries and run with no electricity, which is why they are the ones people buy for outages.

Forced air (torpedo) kerosene heaters such as pick 4 are a different tool. They put out far more heat, need a 120 volt outlet for the fan, and their manuals keep them out of living and sleeping areas. They are for garages, barns and job sites with fresh air coming in. If you want a garage heater, compare our garage heater picks first, which include electric heaters that burn nothing in the room.

Wick care, odor and the first burn

Most kerosene heater smell comes from the wick, the fuel or the moment of lighting and shutting off. The makers' advice:

• Soak the wick, and light it outdoors the first time. Sengoku's HMN-110 manual says to wait 60 minutes after the first fill so the wick becomes saturated with kerosene before lighting, and Sengoku's 23K manual says the first lighting should be done outdoors so the oils and waxes from manufacturing burn off.
• Burn it dry. Sengoku's manual calls for a carbon removal burn in the first 5 to 7 days of use, outdoors or in a room with the windows open because of the smell. Toyotomi says to move the heater out of the living area for its burning dry procedure. Dura Heat says to dry burn and empty the heater at the end of every season.
• Keep the wick clean and at its setting. The CPSC says to keep the wick clean and in good condition by following the maker's procedures, and never to run the heater below the minimum wick-stop setting. Toyotomi's manual says a wick lasts at least one heating season with proper attention.
• Check the shutoff. Sengoku says to check the automatic safety shutoff about once a week in the heating season; Toyotomi says weekly too.

Replacement wicks are model-specific. Buy the one your heater's manual names: pick 2's manual, for example, lists wick OS-0023.

Frequently asked questions

How long will 5 gallons of kerosene last in a kerosene heater?

About 62 to 71 hours in a 10,000 BTU radiant heater and about 30 hours in a 23,000 BTU convection heater at its maximum setting, by the maximum fuel use the makers print in their manuals (0.08 gallons an hour for the Sengoku HMN-110, 0.07 for the Kero World radiant, 0.167 for the Sengoku HMC-23K and the Comfort Glow KW-24J). A lower setting stretches it. Primal Survivor says run time swings a lot with the quality of the kerosene, and owners report shorter runs than the manuals, so buy more than the math says.

How do you light a kerosene heater?

Follow your own heater's manual. For the Sengoku HeatMate HMN-110, Sengoku's manual says to wait 60 minutes after the first fill so the wick can soak, then press the ignition lever fully down and release it once the wick has lit; if the igniter wire is broken or the batteries are dead, it says to replace them. To light it with a match instead, it says to open the front guard, and it warns: "Never leave a burnt match on the wick adjuster or horizontal reflector," because incomplete burning or a fire can follow. It says to wait about 15 minutes after lighting before adjusting the flame, and to wait 5 minutes before relighting if the automatic safety shut-off has tripped.

Can you sleep with a kerosene heater on?

The CPSC's answer is no: "Never operate unvented fuel-burning appliances in any room where people are sleeping." Also, the US Fire Administration says to "turn heaters off when you go to bed," and every wick heater manual we read says to turn it off before going to bed. The model fire code also bars unvented heaters from sleeping rooms.

Can you use diesel in a kerosene heater?

Not in a wick heater. The Comfort Glow, Sengoku, Dyna-Glo and Dura Heat manuals all say to use no fuel other than 1-K kerosene. Some forced air heaters are different: the Dyna-Glo KFA50WH manual allows 1-K kerosene or No. 1 diesel or fuel oil. Follow your own heater's manual.

Is a kerosene heater safe in a garage?

The makers sell them for it: Sengoku's HMN-110 page has a section for machine sheds and garages, and World Marketing's KW-24J page names a garage or workshop. Their manuals' rules come along: Sengoku's HMN-110 manual says to keep 36 inches clear at the top and front, never to leave the heater unattended, and never to use it where "flammable vapors or gases may be present." Bob Vila ran the Sengoku HeatMate in an open garage. A forced air kerosene heater's manual sizes a fresh air opening (1.5 square feet for the 50,000 BTU Dyna-Glo KFA50WH) and asks for clearances of 8 feet at the outlet and 4 feet elsewhere. Kidde says not to install its carbon monoxide alarm in a garage, so put the alarm in the house.

Do kerosene heaters need electricity?

Wick heaters do not. The Sengoku HeatMate HMN-110 and HMC-23K and the Comfort Glow KW-24J light from batteries and burn with no power, which is why they work in an outage. Forced air kerosene heaters need a 120 volt outlet for the fan, so they stop when the power does unless you have a generator.

What is the best kerosene heater brand?

Sengoku (HeatMate and KeroHeat) and Dyna-Glo models appear most often in the roundups we read, and the one wick heater a hands-on tester ran is the Sengoku HeatMate HMN-110. Sengoku makes picks 1 and 2, and World Marketing of America, which sells Kero World and Comfort Glow, makes pick 3 and publishes a current manual for it.

What is the safest kerosene heater for indoor use?

No safety agency names a model. The US Fire Administration says to "only use kerosene heaters from a recognized testing laboratory" and that the heater should have an automatic shut-off that turns it off if it tips over; all three wick picks here list a tip-over shutoff and a UL listing. The fire codes that allow them in homes ask for UL 647, which none of the makers' pages we saved names, so check the label. Beyond the label, the agencies' rules above are about use: ventilation, a carbon monoxide alarm, clearance and never while sleeping.

Which is safer indoors, propane or kerosene?

The University of Alaska Fairbanks Cooperative Extension classes every portable kerosene and propane heater as unvented and does not recommend either inside the home. It says propane is a cleaner fuel with ultralow carbon monoxide emissions, but that unvented propane heaters still need ventilation from outside air. The CPSC lists both fuels among those that make carbon monoxide when they burn incompletely. In Massachusetts, state law bans using or selling an unvented liquid-fired space heater, and in New York City using a kerosene or propane space heater is illegal.

What is the best small kerosene heater?

Of the heaters we link, the Sengoku HeatMate HMN-110 (pick 1). It is the 10,000 BTU heater among the picks, against 23,000 and 23,800 BTU for the two convection picks, its listing calls it compact and easy to carry, and its 1.2 gallon tank lifts out, so only the tank goes outdoors to be filled. A small heater still needs room: its manual's air rule puts the line at about 250 square feet at an 8 foot ceiling, and in a smaller room it says to keep the door to the next room or a window open. The CPSC's advice to run a kerosene heater with the door between the room and the rest of the house open holds whatever the heater's size.

Do kerosene heaters burn clean?

Not completely. The CPSC says kerosene heaters give off low levels of pollutants while they burn, carbon monoxide and nitrogen dioxide among them, which is why the ventilation and alarm rules above apply to every kerosene heater. What the sources tie to a cleaner burn is the fuel, the wick and the flame: the CPSC says to use only water-clear 1-K grade kerosene (other grades can release more pollutants), and to keep the wick clean and never to run the heater below its minimum wick-stop setting, and the EPA says a persistent yellow-tipped flame generally means the heater is out of adjustment and putting out more pollution. Sengoku's manual for pick 2 also has you light it outdoors the first time, so the oils and waxes left from manufacturing burn off. None of the sources names one model as burning cleaner than the rest.
