Many times a simple alternative is not available. So, you may need to use a kerosene heater to reduce the severity of the winter. 

In this case, I am sharing with you some useful steps on how to use kerosene heaters indoors to avoid the risk.

First Step

We know that if a flammable gas comes in contact with this heater, a fatal accident like a fire can happen. Therefore, do not use aerosol spray in the house while the kerosene heater is on. 

If there is gas in the cylinder, make sure that the gas does not leak in any way. It’s common sense stuff, isn’t it? Also avoid putting flammable liquids near the heater. 

Second Step

If you have children in your home, be careful when using a kerosene heater. Refrain from letting children run and play around kerosene heaters. 

Otherwise, if your children touch the hot part of the heater or the flame, it could burn their hands or cause an accident bigger than that. Please share the guidelines for careful use of kerosene heaters with children as well as other family members. 

Inform them about the potential risks of kerosene heaters. A little caution is capable of avoiding major accidents.

Third step

Finally, never keep the kerosene heater on while sleeping. If the amount of oxygen in your home is reduced for any reason, the kerosene heater can produce too much carbon monoxide. 

The same rule applies not only to kerosene heaters, but to any other heater that is powered by organic fuels. Therefore, to prevent carbon monoxide poisoning, make sure to turn off the heater before going to bed. 

You know that if you have any unexpected situations while you are asleep, you may not have time to act quickly.

How long can you run a kerosene heater indoors?

The combustion material of a Kerosene heater is actually the kerosene fuel. So the heater tank has to be filled with fuel at regular intervals. 

Once the good quality kerosene heaters are refueled, you can use them for 4 to 5 hours straight for indoor heating. But it would not be wise to use it continuously for so long. Because you know it can increase the Co poisoning. 

When lighting a kerosene heater in the house, you can meet your needs in less time even if the environment is relatively closed. The good news is that even if you use it for a very short time, you will still get enough heat from a kerosene heater to keep your home warm.

However, it is not possible to use a propane space heater or the indoor space heater in the tent even if you want. In this situation  portable kerosene heaters can be a good choice. But keep in mind that using an oversized heater will do more harm than good.

Kerosene VS Propane portable heater: Which one is better? 

You can use either kerosene or propane heater according to your needs and preferences. I am comparing these two for the convenience of your understanding. 

Kerosene heaters generally consume less fuel than propane heaters. So there is less hassle of refueling and less fuel expenditure. You need a separate propane tank for a propane space heater. But there is no such hassle in any kerosene heater.

You can sleep peacefully with the ventless model of propane heater on. But you won’t be able to fall asleep with kerosene heaters on. 

Kerosene heaters’ combustion material is kerosene. On the contrary, the combustible fuel of the propane heater is a kind of gas (but different from natural gas).
