Things to Know Before Buying a Kerosene Heater for the Indoors

Whether you’re looking for an inexpensive way to warm your well-ventilated workspace or preparing temporary heat for a power outage, a kerosene heater is a great indoor heating option – as long as the room stays well-ventilated.  

  • A kerosene heater is economic and powerful – using little fuel to emit a large amount of heat around itself.
  • Used in portable lamps, kerosene has been a popular light source for ages. The fuel burns cleanly, producing almost no smoke or fumes. When stored properly, kerosene has a long shelf-life.
  • Kerosene heaters are a popular option for emergency heating. You only need a bit of fuel for quick, localized warmth even during a power outage. They’re also used for zone heating, to warm up spaces like garages, individual rooms, or cabins.
  • Warehouses can use kerosene heaters too, but these large spaces require several high-output machines. Luckily, the kerosene heater BTU output ranges from 10,000 to 200,000 BTUs – quite a bit to choose from.
    Choose lower BTU outputs for smaller spaces. There’s no temperature control in kerosene heaters – they always work at maximum heat output. Simply turn off the heater when your room or garage reaches a pleasant temperature.
  • Many kerosene heaters send heat upwards or sideways – leaving your floors chilly. Combine a kerosene heater with a ceiling fan to ensure your room gets heated evenly. Remember to set the fan blades to winter mode for maximum efficiency!

Indoor Kerosene Heaters Buyer’s Guide

Equipping your home, garage, or cabin with the right source of heat can make or break your comfort during the winter months.

Kerosene heaters are the right pick if you’re after a portable heater that quickly warms up entire rooms. They’ll do great if you only have one or two rooms to heat, whether you need supplemental heat or a main heat source for your space. These large, powerful space heaters work quickly. While it takes some time to get your flame all set up, the powerful heat source will warm up your room lightning-fast. The only safety precautions to keep in mind – keep away from flammable objects and commit to regular maintenance!

Are kerosene heaters safe to use indoors?

A kerosene heater is a safe option for heating your home. But, like with any other space heater, following basic safety precautions is a must.

Kerosene is a refined heating oil that comes with few impurities. When it burns, kerosene emits less carbon monoxide than most other heating fuels (including heating oil and propane). That makes it a safer choice for indoor heating, but it’s important to keep your space ventilated!

However, kerosene does have a high carbon footprint, so it’s not exactly an eco-friendly option!

How to Stay Safe with a Kerosene Heater

Even though it’s mostly harmless, you should still be careful when handling and storing your kerosene heater and its fuel. Here are some golden heater safety rules to remember:  

Always use the right fuel

It’s dangerous to use the wrong type of fuel in your heater. Always use 1-K kerosene. Whether that’s regular heating oil, diesel fuel, or impure kerosene, avoid putting anything other than clear kerosene in your heater. Kerosene and gasoline mix particularly badly, so keep their canisters clearly labeled.  

Place your heater smartly

Position your space heater away from flammable objects. Look out for curtains, fabric-upholstered furniture, bed sheets, and loose papers. Make sure you won’t accidentally knock over your heater (placing it near the door is a common culprit).

1. Ventilation is paramount

While kerosene doesn’t produce as much carbon monoxide as other fuels, it rapidly depletes the oxygen in the room. Make sure to let some fresh air in.

2. Store kerosene safely

Store your kerosene in a clean, tightly-sealed, opaque bottle. It’s best to use original packaging or an approved container.

3. Avoid direct contact with the oil

Don’t ingest kerosene and avoid breathing in its fumes. Avoid contact with skin as much as possible since physical contact with kerosene can cause irritation.

In addition, kerosene may stain your floors and it emits a strong, paint thinner-like odor. Make sure you use the right equipment and refuel your heater outdoors.

4. Let cool before refueling

Refueling the tank while the kerosene heater is still warm is playing with fire (literally). Also, never smoke near exposed kerosene.

5. Clean your heater regularly

Cleaning the wick is the most important part of kerosene heater maintenance.

6. Equip your home with a CO and smoke detector

In the case something does go wrong, a carbon monoxide detector will warn you in time. This will ensure you notice the problem quickly, and escape the premises and call 911 as soon as possible.

7. Automatic shutoff and tip-over switch

Check out the safety features your heater comes with, and consult the user manual to learn how to use it the safe way.

Do you need ventilation when using a kerosene heater?

Kerosene is known as a clean, low-viscosity oil that burns very cleanly. It doesn’t emit nearly as much carbon monoxide or other dangerous fumes as propane and natural gas. However, that doesn’t make it safe to use in a badly ventilated space.

As it burns, your kerosene heater will rapidly deplete oxygen. That makes keeping your window cracked open an inch or two an important safety measure. Keep your window open while your kerosene heater is turned on – it’ll help you make sure you always have a supply of fresh air.

Kerosene Heaters: First-time Use and Maintenance Tips

A kerosene heater needs to be set up before use. Unlike power-hungry electric space heaters, it’s not as easy as plug & play. Luckily, you only need to do this once. Set up your kerosene heater and all you’ll need to do later is refill and clean it. 

So, here are a few tips to help you set up and use your indoor kerosene heater for the first time the right way:

  • Always handle kerosene with care. Fill and refill your heater outdoors to avoid dangerous fumes. Use a siphon pump (like this one) or a funnel to fill your heater with kerosene.  
  • When you fill your heater with kerosene for the first time, you’ll need to let it sit for a while. Fill up the tank, and wait for an hour or so before starting the heater. This time is necessary for the wick to get properly soaked in fuel.
  • If you don’t have a fully manual model, you’ll need a pair of batteries to start your kerosene heater with a click of a button.
  • Burn your first tank of kerosene outside. Simply fill up the fuel tank, let it sit, and then turn on your kerosene heater outdoors. This will help break in the machine, burn off the residues of oils used in manufacturing, and season your heater for further use.
  • The smell of kerosene is normal when your heater just starts working and once you turn it off. During heating, you shouldn’t feel a strong odor.

Kerosene Heater Maintenance Tips

  •  Kerosene heaters don’t let you turn the temperature up or down. These powerful machines work quickly and you’ll need to shut them down to stop heating. Simply set up your flame so it goes up around half an inch, let it burn, and turn the heater off once your room is warm enough!
  • Maintain your kerosene heater regularly by cleaning the wick.
  • If you use your kerosene heater as a main heat source, change the wick once a year.
  • Once a month, suck the remaining fuel from the tank, take your heater outdoors, and let it burn and deplete the remaining fuel. This process cleans the wick, removes smells, and helps your heater work at peak performance.
  • Store your kerosene safely, away from your home, in a clean, opaque container.

Do kerosene heaters need electricity?

Typically, no. Kerosene heaters and kerosene lamps are amazing devices to have during a power outage. Whether you want to save electricity, prep for an emergency, or even live off the grid, kerosene heaters are a solid option.

Kerosene heaters virtually remained the same for decades. The most prominent modern addition to it is the ignitor. Its job is to light the wick – and most indoor kerosene heaters today use a battery-powered piezo-electric ignitor. However, some models do require access to an electric plug to start or run an electric fan for forced-air convection heating.

Use the Right Fuel – Know Your Kerosene

Using the correct kind of fuel for your heater is super important. Only pure 1-K kerosene should go into your kerosene heater. Using any fuel other than kerosene can cause your heater to malfunction and pose a fire hazard.

You may have noticed that fuel canisters usually come color-coded. Gasoline is stored in red bottles, diesel fuel comes in yellow, and kerosene is packaged in blue bottles.

Don’t use a bottle that was used to store another type of fuel – even trace amounts of gasoline can wreak havoc on your kerosene heater. Gas and kerosene don’t mix well, so don’t mix up their containers.

A few grades of kerosene are available on the market too. Always use clear, colorless kerosene for your heater, especially when heating the indoors.

Kerosene is a very shelf-stable fuel and it can last for a long time if stored properly.

How to Store Kerosene

If you’re used to burning gasoline, you may be surprised by how much energy you can get with only a little bit of kerosene. The highly calorific fuel is very energy-efficient and burns slowly, giving you a lot of heat in the process. A little goes a long way with kerosene.

Stock up if you want to use it as a primary source of heat. A typical indoor kerosene heater tank holds 1.9 gallons, while the bigger industrial units need 5 or more gallons for a full tank.

Keep kerosene away from your home to avoid a build-up of fumes in your living space. Make sure it’s far from your heating system and away from direct sunlight – fuel canisters should not be exposed to heat.

Always use a clean, opaque container to store your kerosene. Don’t reuse old gas canisters for kerosene – even trace amounts of gasoline can cause issues with your heater, and possibly start an explosion or a fire. 

With proper storage, kerosene is very stable and can last up to 5 years. However, old kerosene is less efficient. Add a fuel stabilizer once a year to extend the shelf-life of your kerosene.

Wrap Up

Kerosene heaters for indoor use are a popular choice for emergency or zone heating. Best of all, kerosene heaters don’t require electricity, so they’re a great option that can help you warm up quickly even during a complete blackout. 

These machines are sturdy and durable (some people still use units bought in the ‘80s), which makes them an excellent investment.
