Kerosene Heater FAQ

3) Can I leave kerosene heater on all night?
You should never leave any fuel sourced heater unattended for any period of time. You should look into infrared heaters if you find that you are cold throughout the night. They are safe for overnight use.
Another option is to insulate your garage so you won’t need to use any heating source.
4) Do indoor kerosene heaters smell?
Bad smells coming from low-quality fuels sourced from fuels with high sulfur content, old fuels, and low-grade kerosene which doesn’t burn. You should always check the quality of your kerosene fuel quality, I found a great guide for doing so here.
5) Do you need to vent a kerosene heater?
Yes, open a window or the garage door if you plan to use this inside. Since these units don’t have oxygen depletion sensors you will want to ensure that there is enough air circulating at all times.

6) What is the difference between K 1 kerosene and regular kerosene?
K1 Kerosene is a very pure form of kerosene while K2 kerosene can have up to 10 times the amount of sulfur. Since you’re going to be indoors using these heaters, always use K1 kerosene as a heat sourcing fuel.
7) How long will a gallon of kerosene burn?
A gallon of kerosene should burn 9-12 hours depending on the quality of your fuel.
8) What happens if you put gasoline in a kerosene heater?
Gasoline is much more volatile than kerosene and can erupt on ignition. Do not under any circumstances put anything besides kerosene in your kerosene heater.
9) What is the cleanest burning kerosene?
Type 1 Kerosene is going to be your best bet to reduce any odor coming off of your heater.
10) Does kerosene gel in cold weather?
It does not gel up during the winter, so you should be able to store it properly without worry.
