When to Use a Non-Electric Heater

Before you consider purchasing a non-electric heater, it’s important to understand their limitations. A non-electric heater shouldn’t replace your home’s primary HVAC system.

Attempting to use a non-electric heater as the main source of heat for a home presents several hazards. Gas heaters can produce high carbon monoxide levels in your home, which can cause illness and even death if not carefully monitored. Non-electric heaters also use an open flame and fuel, creating a potential fire hazard.

For these reasons, non-electric heaters should never be left unattended for long. If you’re looking for a primary heat source for your home, you’ll need to shop for an HVAC system.

Types of Non-Electric Heaters 

Non-electric heaters fall into three different categories: propane, natural gas, and kerosene. While all three will do the job when it comes to providing heat, they each operate differently. Understanding which works best for your needs is key to making the right decision when purchasing a non-electric space heater.

All non-electric heaters produce radiant forced air or convection heat.

  • Radiant heaters generate infrared heat using metal tubes that radiate heat, which warms the room. With radiant heat, the closer you are to the heater, the warmer you get.
  • Convection heaters function by heating the air around them. They are tower-shaped and emit heat in all directions.

If you’re a football fan, then you‘ve likely seen propane and kerosene forced-air heaters warming the sidelines of games played in sub-freezing temperatures. Forced-air heaters have a distinctive cannon shape and function by blowing heat in one direction. They are mighty but noisy, which makes them attractive for commercial use but impractical for home use.


Propane heaters come in various forms, ranging from the tower-shaped outdoor heaters to smaller portable heaters. Propane heaters use refillable tanks and canisters ranging in size from 16-ounce canisters to a 20-lb tank.

Because the fuel comes in small canisters, radiant propane heaters can be small and portable. You can even mount some models on the wall.


Kerosene burns efficiently and heats very quickly, making kerosene heaters an ideal option for supplemental home heating. Like propane, kerosene heaters fall into three categories: radiant, convection, and forced air.

Kerosene heaters use liquid kerosene, which is available at most home improvement stores. Unlike propane, which uses a spark for ignition, kerosene requires a wick.

Natural Gas

Nearly half the homes in the U.S. use natural gas as their primary heat source, according to the U.S. Energy Information Administration. If you’re in that half, then a natural gas non-electric heater might be for you.

Natural gas heaters function similarly to propane heaters, but instead of needing a tank, they tie directly into your home’s gas line. This set up eliminates inconvenient trips to refill a propane tank. However, if you do opt to use natural gas, you sacrifice the portability of your heater, which you must install close to a fixed gas connection.

Do keep in mind that you cannot hook up a propane heater to a natural gas line. Only install heaters designed for use with natural gas to a natural gas line.

What to Look for When Buying the Best Non-Electric Heater

Before purchasing a non-electric heater, it’s important to think about what size and type of heater best fit your needs. Manufacturers rate heaters for indoor or outdoor use. Weight is also an issue, especially if you plan on moving the heater from location to location. Also consider tank size, as this will dictate how often you’ll need to refuel the heater, and power, which determines just how much space you can expect the heater to warm up.

Indoor vs. Outdoor Use

Determine whether you plan to use the heater indoors, outdoors, or both. Outdoor-only heaters create intense bursts of heat that won’t quickly dissipate into the surrounding air. As such, they are significantly more powerful than indoor heaters, which benefit from four walls and a roof.

Energy is measured in British thermal units (BTUs). Whereas 5,000 BTUs might be adequate for indoor use, an outdoor heater may need more than 40,000 BTUs to keep an open-air space warm.

You can use many portable non-electric heaters indoors and outdoors. Make sure to check the heater’s ratings before making a purchase.

Weight and Portability

Decide what you want out of a non-electric heater: a heater for a dedicated space or a unit you can move from place to place. Knowing how you plan to use your heater can help you determine whether to look for a portable or stationary unit.

Portable heaters weigh anywhere from 20 pounds to as little as 5 pounds, and are available as radiant, convection, or forced air varieties. Many portable heaters feature impact-resistant construction and large handles for easy transport. Some even come with carrying cases.

Larger non-electric heaters, such as the powerful tower heaters you find on backyard patios and in outdoor eating areas at restaurants, weigh upwards of 70 pounds, not including the 20-pound tanks that power them. While these are not portable, most have wheels that allow you to reposition them. Other permanent heaters include kits that enable you to mount them on a wall or to the floor.

Tank Size

Tank size determines just how long your heater will work before it’s time to replace the fuel.

  • Kerosene heaters have tanks that hold liquid kerosene. A kerosene heater with a 1-gallon tank will provide about 14 hours of use before needing more fuel.
  • Propane works differently. Because propane gas is a compressed liquid, it comes in tanks that attach to the heater via a valve and hose. Larger heaters use a 20-pound tank, which provides about 10 hours of use. Portable propane heaters use 16-ounce canisters, which last about three hours.

Whereas most kerosene tanks include fuel gauges, most propane tanks do not, making it difficult to know just how much remains in the tank.


It’s best to take the Goldilocks approach when selecting a gas heater: A heater with insufficient power will leave a room too cold, a heater that is too powerful will make it too hot. You want a heater that’s just right.

More BTUs mean more heat output. Most manufacturers also rate their indoor heaters by square footage. For example, an indoor heater with a maximum BTU of 9,000 can heat up to 225 square feet.

Outdoor-only heaters, such as tower-style patio heaters, can have a BTU output higher than 40,000. Indoor and portable heaters typically have an output of around 5,000 BTUs.

While it’s tempting to get the most powerful heater you can afford, you might regret it. A heater with a high minimum BTU output will quickly overheat a smaller space, making it challenging to regulate the room temperature. Unless a sauna is what you’re after, make sure you pay attention to square-footage ratings when deciding which heater will give you that just-right temperature.

Safety Tips for Using Non-Electric Heaters

Because non-electric heaters involve fuel and flames, it’s essential to follow certain safety guidelines and consider only models with standard safety features. A non-electric heater should have tipping and low-oxygen sensors that shut off the heater when triggered. A safe heater will also have a shield that prevents contact with an open flame, such as a glass window or metal grate.

Even with these safety features, it’s also essential to follow some common-sense practices when using a non-electric heater. Make sure to place the heater in a low-traffic area to prevent people and pets from bumping the unit. Set up non-electric heaters on even ground to avoid fuel spills or flame exposure. Also, allow for a buffer of at least 3 feet between the heater and flammable materials.

  • Only purchase a heater with built-in safety features
  • Allow for a buffer of at least 3 feet between flammable materials and the heater
  • Make sure the heater sits on even ground
  • Keep the heater out of high-traffic areas
