What Is a Kerosene Heater?

Paraffin Heater

Also called a paraffin heater, a kerosene heater is an unvented portable space heater. It is a primary source of heat in many Japanese homes. Meanwhile, in Europe and the United States, it is more commonly used as a supplemental heating device, especially when there is a power outage. 

Has a Cotton or Fiberglass Circular Wick

While the design can vary from one model to another, they work almost the same way. It has a cotton or fiberglass circular wick. The kerosene goes through the wick through capillary action. After lighting the wick, it heats up and turns into gas. In turn, it heats the room through convection or radiation. 

Over the years, kerosene heaters have been more innovative. For instance, many of them now have an electric fan that forces heated air, making it quicker to warm your garage. 

How to Choose a Kerosene Heater for Your Garage

While the options are plenty, it does not mean that they are all the same. To narrow down your choices, below are the factors you should take note of:

1. Type 

The specific type of garage heater is crucial as it will give you an idea of how it works: 

Convection Kerosene Heater

It is often round and throws heat in the garage at 360 degrees. It is the best option if you have a large garage. 

Radiant Kerosene Heater

For smaller spaces, a radiant heater is better. It is often rectangular and will not heat at 360 degrees. It can heat items around, such as curtains, making it a fire hazard. 

2. Power 

This is indicative of the unit’s heating capacity. One of the most important technical specs to look at is the BTU. It measures thermal energy and dictates how hot the heater can get. A higher BTU means that it is more powerful. Nonetheless, it can also mean larger and will use more fuel. 

3. Coverage 

Before buying a kerosene heater, consider the size of the garage and match it to the product you will purchase. Most manufacturers will indicate the maximum square feet capacity of their garage heater. 

4. Tank Capacity 

The larger the tank, the longer the heater can run without refueling. Most garage heaters will have a tank accommodating up to ten gallons of fuel. Many companies will indicate their average runtime. 

5. Ease of Use 

From daily operation to care and maintenance, think of the things that will make the garage kerosene heater user-friendly. It should come with comprehensive instructions. There should also be a diagnostic display, which will make it easier to determine a problem. 

How to Use a Garage Kerosene Heater 

The specific steps might differ depending on the model that you are using. In most cases, however, here’s how you can operate a kerosene heater in your garage:

  1. Pickup fuel for your kerosene heater. In most cases, you will be using 1-K kerosene. It burns clean without leaving foul odor, making it great for indoor spaces. 
  2. Open the fuel cap and fill it with kerosene. Close the cap once you are done filling the tank. 
  3. Let the wick soak for an hour. This is especially important if it is your first time using the kerosene heater. 
  4. Switch it on or urn the knob to activate the heating function. 
  5. Adjust the temperature as you deem necessary.

Is It Safe to Use a Kerosene Heater Indoors?

To ensure safety, below are some of the most important things to do: 

1. Provide Enough Ventilation

Kerosene heaters emit carbon dioxide and other pollutants, which are dangerous upon inhalation. 

2. Do Not Operate the Heater Next to Flammable Objects

It must be at least three feet away from combustible materials.

3. Use the Right Fuel

1-K kerosene is the most common. Using the wrong fuel can result in safety hazards and damages to the heater. 

4. Refuel the Heater Outside the Garage

Many models have wheels, so moving it outside is easy.

This way, you will easily know once a fire has started because of the kerosene heater, and you can respond immediately.
