How to Choose a Non-Electric Space Heater

After a power outage, research about non electric space heaters was high priority. Much of that research was saved here.

The best non-electric space heaters.

Heating Without Electricity

Electric heaters may be the most common and simplest-to-use portable heaters, but the electricity required to run them is often quite expensive. Also, electric heat will be worthless if the electric power goes out due to a storm or other disaster.

A portable non-electric heater can be both a lifesaver in an emergency and an effective supplement to back up your primary heat source. When cold winter weather hits, be ready with a heat backup that runs on an alternative fuel source, such as propane, natural gas, or kerosene.

Here you'll find a review of the best units on the market, based on consumer reports, Amazon reviews, and personal experience.

What Are the Different Types of Space Heaters?

  • Radiant heaters: These heaters use infrared radiation to directly warm the areas in front of them. They are relatively quiet and use little fuel, but they do not have a large range.
  • Forced-air heaters: This type uses a fan to blow the hot air out of the unit. While they can be very noisy, forced-air heaters are powerful, and they warm things up really fast.
  • Convection heaters: This heater draws in cold air and then heats it up at the top of the unit via heating coils. This is great for heating up moderately-sized rooms, but they can get noisy.
  • Radiators: These heaters work by warming heating oil enclosed in a reservoir, and that heat radiates out and heats up the surrounding area. Due to their slow speed, they are not that ideal, but they are very quiet, so if you are looking to warm up a small room and you're not in a hurry, a radiator works well.

Space Heaters That Don't Require Electricity

The most common alternatives to portable electric heaters are gas and kerosene heaters. Gas heaters can be powered by either natural gas or propane.

Disposable propane tanks (bottles) are easy to use and best for emergencies. Keep at least two bottles of the disposable propane tanks for minimum preparedness for a power outage.

  • Propane heaters can also be hooked up to much larger permanent (not disposable) tanks. When you purchase a propane heater, the unit will include a hose attachment and regulator.
  • Kerosene heaters will burn fuel slowly and efficiently. A gallon of kerosene can last 12-16 hours, which is longer than a wheelbarrow full of wood. Kerosene heaters are a great solution for camping, trailers, basements, or garages.

Pricing and Suggested Brands and Models

Non-electric heaters are available in many brands and price ranges.

  • Propane heaters cost from $80 to $250. The Mr. Heater Portable Buddy Propane Heater (featured below) is a recommended brand in this price range.
  • Kerosene heaters run from about $150 to $350.
  • Natural gas heaters run from $130 to $230.

Of all the types of heaters reviewed, this reviewer recommends the Mr. Heater brand for any category of non-electric space heaters. They are quality built and flexible.

Propane Heaters

Getting a portable propane heater can be a great option. Below, I have listed three of the best portable heaters that run on propane. Some are more portable than others but it all really depends on what you are using the heater for.

Mr. Heater MH18B

This "Mr. Heater" propane unit gets rave reviews and compliments for its safety features.

Safety features might make this unit temperamental, however, as an emergency heat source, it's well-built and flexible. It also comes with an AC adaptor. Perfect for tent, camper, garage, or emergency conditions such as a power outage. It can be used indoors safely.

Important: When you use this heater with a 20-pound propane bottle and accessory hose, you must shut the tank off first, before the heater, and let the heater run until it burns off all the fuel in the lines. That's because if you just turn the knob off, propane gets trapped in the accessory hose—not good for the unit.

High-pressure propane sitting in the rubber hose will chemically react with the rubber and leach out a light oil that will build up and work its way into the heater, clogging up both the regulator and the control valve.

Consider purchasing the gas line filter, because it will catch this oily residue. This protects the combustion components of the heater and eliminates the safety issues described above.

Fuel Needs: Two disposable propane tanks will burn for six or seven hours on the low setting. Also, you must have two of the disposable cans on hand in order to run it on high at all; it does not say this in the manual. On the high setting, those two canisters will last at least three hours.

Both the gas line filter and the disposable propane bottles can be purchased via Amazon at a reasonable price and with free shipping too (with a minimum purchase).

Dyna-Glo RA18LPDG

The Dyna-Glo RA18LPDG is a larger cabinet heater that comes in at a whopping 18,000 BTUs. With its sturdy casing and wheels, this heater is a beast that can be used in a variety of different situations. If you need to heat a large room or a workspace/garage, this is an ideal heater choice. The unit features three burners each rated at 6,000 BTU. This gives you three different options when it comes to heat.

The heater also has an oxygen sensor to ensure that there is enough oxygen in the room and if there is not, it will stop working and shut off. The "tip-over" sensor can get a little too finicky, so trying to move this heater while it is turned on will probably not work. The benefit of this is that if the unit does actually tip over, it will turn off and prevent any major incidents.

Fuel Needs: One 20-pound tank of propane can last for up to 64 hours on the lowest setting.

Kerosene Heaters

If propane is not your thing and you are looking for a heater that will warm you up faster, kerosene is a great option. While kerosene is more expensive and harder to get than propane, if you're facing extreme weather conditions or you want something with more BTUs, pick up a kerosene heater.

Sengoku Heat Mate Radiant Kerosene Heater

This lightweight heater is only 27 pounds, yet it has some pretty impressive capabilities, with 10,000 BTUs and a range of 400 square feet. Another positive aspect of the Sengoku Heat Mate is that the heater is a large tank that can hold 1.2 gallons of kerosene, which can last up to 14 hours.

The wick can be a bit unstable at times and wear out quickly, so make sure that if you have this heater you get some replacement wicks as well. It also has a battery-powered starter, so keeping some extra batteries around is another good idea. One of the major downsides of this heater is that it was made in China, meaning that its craftsmanship is of questionable quality and some of the components may not last very long.

Dura Heat Portable Forced Air Heater

If you are looking for a powerful heater that will warm things up quickly, the Dura Heat is a great option. Coming in at 75,000 BTUs, the heater will raise the temperature in a hurry. The heater comes with a built-in thermostat and a fuel gauge, which are both quite helpful. Another positive is that it can run on other fuels besides kerosene, such as #1 and #2 fuel oil and diesel, JP-8, and Jet-A fuels. While it does burn through fuel quite fast, it does not take that long for things to heat up once it's on, so it is fairly economical.

The biggest downside is that the heater requires electricity to properly function, so because of that, it's just not as helpful as other portable heaters. This heater is best suited to use in a garage or workshop that gets incredibly cold during the winter. In that situation, it's great, so long as you have electricity. The heater also gets really loud, so you should place it in the corner away from where you will be standing.

Kero World KW-24G 23,000-BTU Indoor Portable Convection Kerosene Heater

This convection heater is great to use in large indoor areas as it is really good at spreading out the heat, and with a range of 1,000 square feet, it can be used in a variety of situations. The Kero World KW-24G is pretty powerful at 23,000 BTUs, and it has a large fuel tank that can hold 1.9 gallons of kerosene. This gives the heater up to 12 hours of heating time on one tank.

Another thing I like about it is the metal grille that covers the heating unit, which prevents any major risk of injury while the heater is on.

The heater does use batteries for its ignition system, but so far I have not had any issues with it. Just keep in mind that you will need some extra batteries lying around the house to use as replacements.

Do Electric Space Heaters Save on Energy?

Electric heaters might not be the best choice. According to Consumer Reports (Feb. 10, 2010), claims for electric heaters don't add up:

Manufacturers of electric space heaters want you to believe that using one of their devices will lower your heating bill. Lowering your home's thermostat(s) and using your main heating system less in tandem with a space heater--called zone heating--will cut your utility bill. (Every degree you lower the thermostat(s) can save you about 2 percent on your heating bill.) But keep in mind that based on current national average prices and adjusting for the energy losses due to burning a fuel, heating with electricity is about two and a half times more expensive than heating with gas, the most common heating fuel in this country.

We have little control over the utility companies. Gas or electric, they can raise prices at any time. A power outage leaves us vulnerable.

It is best to have a Plan B of some kind ready. These non-electric space heaters can make a huge difference for you and your family.

Pros and Cons of Non-Electric Space Heaters

Consider these advantages and disadvantages of non-electric portable heaters.


  • These heaters' biggest advantage is they will work during a power outage or anywhere at all where you need heat.
  • Kerosene heaters use a dual-combustion system that burns cleanly and efficiently.
  • Both propane and kerosene are inexpensive alternative fuel sources that may be purchased ahead of time and stored safely.
  • Non-electric space heaters are useful for camping or in any situation where electric outlets are not available. Some also use them to avoid high utility bills for electricity use.


  • Non-electric space heaters are considered less safe than electric heaters, mainly because handling gas can be dangerous.
  • Consumer Reports recommends their use only in emergencies. Still many use non-electric space heaters in many situations quite safely. Use them as directed.

Safety Guidelines for Non-Electric Portable Heaters

While space heaters do offer consumers an important alternative heat source, they come with some safety issues and concerns. Propane and kerosene heaters usually have an open flame, which means they may blow out in windy places. Also, they do emit carbon monoxide so they must be used vented. Additional risks are associated with handling fuel.

Do check local regulations before using a non-electric heater and follow safety guidelines and instructions provided by the manufacturer. If these heaters are used indoors, particular attention must be paid to safety.

Tips for Using Portable Heaters

  • When buying a heater, make sure it has the UL mark, which stands for United Laboratories. This means the unit was tested by an independent laboratory.
  • Turn your non-electric space heater off before leaving a room or going to sleep.
  • Always supervise children and pets when using a space heater.
  • Don't use a space heater to dry clothes.
  • Allow heater to cool down completely before adding fuel.
  • IMPORTANT! Turn off the fuel first, let the remaining fuel burn off, and then turn off the unit.

Crisco Candle as a Nonelectric Heater

This may seem like a joke as an option for a nonelectric heater, but some folks swear by it. May as well bring home a can of Crisco and a couple of lantern wicks just in case. They say Crisco works great as a candle and is much cheaper. Grab some large lantern wicks and shove them into the Crisco.
Another option is to melt the Crisco, let it cool then pour it in a glass jar - that way it gives more light than in the can. You can also use candles cut to the size of the jar and just stick it in the Crisco for a wick too.
Of course, you'd have to watch this open flame closely to prevent home fires. Some say they put it inside the oven for better safety and to create radiant heat. Not the best option, yet some claim this saved them during a power outage - not a lot of heat but some is better than none.

This lens has some great tips and ideas. We'll be using the lens when we look for a heater

Susan Deppner from Arkansas USA on January 08, 2014:

When we rebuilt our house we included a gas fireplace, a great choice that we used during our recent ice storm and three days without power. It kept our house at 73 degrees (warmer than we usually have it) and our gas bill was very reasonable. If we had to choose another heater, it's good to know about these propane and kerosene alternatives. I appreciate your reviews!

burntchestnut on December 13, 2013:

Definitely something to consider if you live in a cold climate and don't have a generator.

Baddew Fibes on December 13, 2013:

Really informative lens and nicely set out. Thank you!

Doc_Holliday on November 27, 2013:

These would be really handy in a power cut.

Do-It-Yourself-Solar on November 11, 2013:

Cool! This thing can bring anywhere you are, a non electric thing. Fantastic.

Carolan Ross (author) from St. Louis, MO on October 23, 2013:

@SavioC: Yep, those who camp in wintertime use them in tents and campers. I never go camping in cold weather so have never done this, but do know some of those crazy kind of people. *wink*

SavioC on October 23, 2013:

Great product since its non electric hence can be used outdoors too. Nice share.

Carolan Ross (author) from St. Louis, MO on October 22, 2013:

@anonymous: No, you live in a tropical climate where folks won't likely ever need non electric space heaters. And YES I am jealous! *wink*

anonymous on October 22, 2013:

I didn't even know these existed... dear Gosh woman, I live in a hole.

Cynthia Haltom from Diamondhead on May 05, 2013:

I have used a kerosene heater before they are very efficient and it requires some practice to fill one. I found the heat produced kept us cozy and warm the winter the heat went out when I was living in the north.

pigwear on February 15, 2013:

Very well put together lens. Also a very practical lens in this day and age! Great job.

GeorgeDornty on February 15, 2013:

Great lens!

IsrealLukasiewicz on February 05, 2013:

I do sometimes

DanielTorri on January 30, 2013:

Nothing like a nice kerosene heater in the winter :)

Tony Payne from Southampton, UK on January 29, 2013:

We used to have a propane heater years ago, and it chucked the heat out, plus it was quite efficient to run in the winter. Great for keeping the conservatory warm too.

Elsie Hagley from New Zealand on January 16, 2013:

Nice lens. We have always got our log fire. Plenty of timber on the farm. Getting our woodshed filled up now ready for winter in New Zealand about May. Blessed

TarahFlesch on January 04, 2013:

Space heaters have definitely saved me some $$$ this winter!

jamesdesalvo lm on December 22, 2012:

I had a kerosene heater when I lived up north in Japan. The thing smelled to the high heavens. Some of these choices seem a lot better. Great lens.

Carolan Ross (author) from St. Louis, MO on December 19, 2012:

@MEDerby: minus 40 degrees? Oh my, that is serious cold. You most definitely need a non electric space heater - or two. Stay warm!

myspace9 on November 20, 2012:

Informative lens. thanks.

M E Derby on November 16, 2012:

Excellent information. I live where it gets down to minus 40 and am looking for a safe non-electric heat source for a power outage.

Totus Mundus on November 08, 2012:

I like the idea of these, always best to be prepared.

WriterJanis2 on November 07, 2012:

This is a great idea to have during the winter months.

aishu19 on October 03, 2012:

I think you should have a non electric space heater as back up. Power outages have the worst timing and could come in the midst of winter

anonymous on February 27, 2012:

Having a non-electric back up is very important. A few winters ago we had a terrible ice storm that knocked the electric out for days and we had no source of heat. We had to climb into bed under covers and stay put the entire time. We live so far out in the country that we were cut off from everyone, no cell phone service area, the phone lines were down, it was down right ancient the way we had to live for days. No way to cook, heat, or do anything.

anonymous on February 10, 2012:

I have one of the Kero World kerosene heaters and love it. It comes in handy when the power goes out, or just to take a chill out of the room I'm in. Everyone should have some back-up heat supply, never know when we will need it.
