How to use an oil burner
Updated: 22 October 2026
How to use an oil burner, in the short-bowl sense, is water first, then a few drops, unless the listing is for wax melts, and the flame out before you leave. The models are on our [oil burner comparison](/hub/heating/oil-burner). Whether the dish is for wax is on [wax melts vs essential oils](/hub/heating/oil-burner/sub/oil-burner-wax-melts-vs-essential-oils). Peter F. checked the listings and public UK sources. There was no lab test. A qualifying purchase can earn a commission at no extra cost to you.

Set the dish before you light anything
Put the burner on a stable, heat-resistant surface, away from curtains and anything a tea light can soften. London Fire Brigade notes that tea lights can melt plastic. Ashleigh & Burwood starts with a chip check: if the ceramic or glass is cracked, do not light it. Scottish Fire and Rescue says the same for essential-oil burners.
Add water before any drops on an oil burner. Kenji asks for the bowl about half to two-thirds full, then the oil. Ashleigh & Burwood and Puckator both say about two-thirds. Dukhni Oriental is oil in water, not oil in a dry brass bowl. If the listing is only for wax melts, skip the water. Village Wax Melts’ wax method is dry.
Drops, without one magic number
Kenji suggests about 3 to 5 drops after the water. Puckator suggests about 6 to 10. Dukhni’s bullets say 8 to 10 drops of oud or similar oil in water. Those are three ranges, not one dose. Use the number on your bottle or burner if it prints one, and do not fill the bowl with neat oil. Scottish Fire and Rescue asks for a small amount of oil and says not to let it burn right down.
Ashleigh & Burwood says not to pour lamp fragrance or reed-diffuser refill into the bowl. If the water boils away, put the flame out. Do not refill a hot, dry dish. Dukhni reviews describe spitting when the water runs low.
The tealight and the four-hour habit
Use one standard unscented tea light in a metal cup, as Kenji and Puckator describe. Do not stack lights, and do not use an 8-hour tea light in a dish built for a standard one. Puckator warns that a flame too close can shatter the dish. Kenji asks for at least about 6.5 cm above the flame on their burners, and about four hours as the long end. That is their habit, not a timer in GeeRic or Dukhni.
Stay in the room. Never unattended is Puckator’s line and the fire services’ line. If you are using wax melts, follow that melt’s fill and only in a dish the listing allows.
Put it out, then let it cool
Extinguish the tea light before you leave the room and before bed. London Fire Brigade’s candle page and bedtime checks both put oil burners in that group. Do not carry the burner while it is alight. Ashleigh & Burwood says let it cool before you move or empty it.
Electric warmers are a different control. Switch them off and unplug them. None of the electrics here that print automatic shut-off say yes. Flame against plate is electric wax melt burner vs tealight. Choosing the dish is the oil burner buying guide.
Common questions
Do I add water before the oil?
Yes, on a burner that is meant for essential or fragrance oil. Kenji, Ashleigh & Burwood, and Puckator all put water in first, about half to two-thirds of the bowl, and the drops go into that water. Dukhni’s bullets describe the same order. A dry bowl of neat oil is not the method those guides describe. If the listing is a dry wax-melt dish, do not add water just because an oil guide did.
How many drops should I use?
There is no single count across the sources. Kenji says about 3 to 5 drops in a small bowl. Puckator says about 6 to 10. Dukhni’s listing says 8 to 10 for its own oil-in-water bowl. Follow the number printed on your burner or oil if there is one, and keep it to a few drops in water. More oil does not fix a dish that has boiled dry. It is more likely to spit.
Can I use an 8-hour tealight?
The guides used here specify a standard tea light, one of them, in a metal cup. An 8-hour light is a different flame height and a longer burn than those instructions. Kenji also caps their own burners at about four hours and wants about 6.5 cm above the flame. A longer light is not a way to leave the room. You still extinguish it when you go.
Can I pour reed-diffuser refill or lamp oil into the bowl?
No. Ashleigh & Burwood’s user guide tells you not to put lamp fragrance or reed-diffuser refill into an oil-burner bowl. Those liquids are made for a different job. Use an essential or fragrance oil that the burner listing actually names, and only a few drops in water. If the only bottle you have is a reed refill, leave the dish empty of it.
What if the water boils away?
Put the flame out. Do not pour cold water into a hot, dry dish, and do not keep the tea light going because a film of oil remains. Scottish Fire and Rescue says not to let the oil burn right down. Dukhni reviews describe spitting and splatter when the water is gone. Extinguish, let the bowl cool, and start again later with water first if you want another session.
When do I put it out?
When you leave the room, before bed, when the water is low, or when you have hit the time limit your own burner prints. London Fire Brigade includes oil burners in the candles you extinguish rather than leave. Kenji’s four-hour line is an example of a maker’s limit, not a reason to stay out of the house. Cool the dish before you empty or wash it.
