I have been using an upright kerosene heater. Due to the warm weather here in NC, I have not had a chance to crank it up. But I have recently purchased a new flat top kerosene heater. I have some left over kerosene from last winter and was wondering if it would alright to use the kerosene that I have on hand or would it be prudent to go and get some new or have some new mixed in with the old?

I would like some answers ASAP for a winter storm warning is in effect for tomorrow in my area. Thank you all.

Please keep in mind -- there is the danger of Carbon Monoxide poisoning with ANY open flame combustion.

Pay attention to the warnings on the packaging and on the unit.

Open flame space heaters, such as a kerosene heater, need to be used in a WELL VENTILATED space. A HEADACHE, or feeling of drowsiness are among the FIRST SYMPTOMS of overexposure to CO. Carbon Monoxide is invisible, and odorless.... Please do not operate this unit without a CO detector in the room. It could save your life.

With the recent power outages across Missouri, many people were using portable generators. One family had a generator in their garage. The wife went out to fill the tank... and was dead before she reached the generator... that is how quickly CO in an enclosed space can kill.

Interestingly -- Most manufactured home builders will VOID your warranty, if you use a Kerosene heater in a mobile or modular home.

As to the kerosene you mention, any flammable liquid can absorb water (most often by condensation inside the container), and this will cause the fuel to burn less efficiently, and to smoke more. My personal solution to this, would be to set the heater OUTSIDE, and burn the old fuel up. Then start with some fresh fuel...again.... burning it for a while OUTSIDE, to make sure the old fuel had been completely consumed. Naturally, you want to do this in a safe location.

I personally prefer to use electric space heaters (ceramic, or oil-contained - radiant) and a generator. The generator can also help power your refrigerator, and/or some lights, depending on it's size. I place the generator OUTSIDE the home, and run a very heavy duty extension cord to inside the home. This keeps my family warm, with lights, and safe from carbon monoxide poisoning.

Be Safe (and good luck with the storm)

I want to get a kerosene heater for emergencies. Is this a good one, or should I stay away from it?

The danger from fire is very high with kerosene. Seven people died a week ago in Philli from explosion and fire from gasoline in kerosene heater. Consumes room air, not allowed in bedrooms. The cost of kerosene is high. For emergencies, "Any port in a storm", any heat is better than no heat. I buy lots from Home Depot, get one that has not been opened.
