Oil burner, wax warmer, wax melter, fragrance burner. The names overlap and the products genuinely differ, mostly in how the heat is produced.
The actual difference
| Oil burner | Electric wax warmer | |
|---|---|---|
| Heat source | A tealight underneath | An electric bulb or heating plate |
| Flame | Yes | No |
| Takes | Fragrance oil in water, or wax melts | Wax melts only |
| Needs | Tealights, replaced constantly | A socket and a cable |
| Temperature | Hotter, and variable | Lower and more consistent |
| Scent | Faster and stronger, with more risk of scorching | Gentler and longer lasting |
| Running cost | The cost of tealights | A few pence of electricity |
The confusing part is that both are sometimes called burners, and a ceramic oil burner used with wax melts is doing the same job as an electric warmer by a different route.
Which gives more scent
An oil burner, in the short term. The higher temperature releases fragrance faster, so a room fills more quickly.
The trade off is that higher heat also breaks down fragrance compounds, which is why a burner run too hot or run dry produces a burnt smell. An electric warmer at a lower steady temperature releases more slowly and the wax lasts considerably longer.
If you want a room scented within ten minutes, a burner. If you want a gentle scent across a whole evening, a warmer.
Which is safer
The electric warmer, straightforwardly, because there is no flame.
That matters in specific households. Rented accommodation with a no candles clause, homes with young children or cats, and anywhere a flame would be left unattended. An oil burner in use holds hot liquid over an open flame and should never be left.
Neither is dangerous when used properly. The difference is what happens when someone forgets.
Which we sell and why
Ours are oil burners rather than electric warmers, and the reasoning is partly aesthetic and partly practical.
A ceramic burner is an object when it is not in use. An electric warmer is an appliance with a cable, and a cable running across a shelf undoes the effect you were creating.
Our range starts at £6.99 for the classic shape, with square burners at £7.99 and sitting Buddha burners at £10.99.
Oil or melts in a burner
Both work in ours and they behave differently.
Fragrance oil goes into water, a few drops at a time. The water moderates temperature and evaporates first, so the oil is never heated alone. The drawback is that the water runs out, and a dry dish scorches immediately.
Wax melts need no water and last far longer per use. They do not run dry in the same way, and spent wax lifts out cleanly. For most households they are the more forgiving choice.
Our guide to what to buy with an oil burner covers the practicalities.
Bowl depth, which decides everything
Worth knowing before buying any burner. A shallow dish heats its contents fast, and fast heating is what breaks fragrance down into that burnt smell.
A deeper dish holds more, heats more slowly and releases scent over longer without scorching. Height above the flame matters equally, because a dish sitting almost on the tealight will scorch regardless of depth.
Our square burners have the deepest dishes in the range, which makes them the most forgiving.
Running costs compared
Closer than people assume. A four hour tealight costs a few pence, and an electric warmer costs a few pence of electricity for a similar period.
Where the difference shows is in the wax. An electric warmer at a lower temperature extracts fragrance more slowly, so a cube lasts across more sessions. Over a year that is a real saving, though a modest one.
Which should you buy
An oil burner if you want an object rather than an appliance, if you want scent quickly, or if you like the ritual of lighting something. Ours are all under £11.
An electric warmer if you are in rented accommodation with restrictions, if there are small children or cats, or if you want to leave it running unattended, which you genuinely should not do with a flame.
Questions people ask
What is the difference between an oil burner and a wax warmer?
An oil burner uses a tealight underneath. An electric wax warmer uses a bulb or heating plate. The burner runs hotter and scents faster, the warmer runs cooler and lasts longer.
Which is safer?
The electric warmer, because there is no flame. That matters in rented accommodation with no candle clauses and in homes with young children or cats.
Which gives stronger scent?
An oil burner in the short term, because higher heat releases fragrance faster. The trade off is a greater risk of scorching and shorter wax life.
Can I use wax melts in an oil burner?
Yes, and for most households melts are more forgiving than oil in water, because they do not run dry and the spent wax lifts out cleanly.
Why does bowl depth matter?
A shallow dish heats its contents fast, which breaks fragrance down and produces a burnt smell. A deeper dish heats slowly and releases scent for longer.
