Wax melts or candles: which lasts longer

A wax melt is a candle with the wick taken out. That single difference decides nearly everything else — how it's heated, how long it lasts, and what an evening of it costs.

A candle heats its own wax with its own flame. A melt has to be heated by something else: a tealight underneath, or an electric burner.

In short. Melts are cheaper per hour and safer; candles are the better object. On our own shelf a box of eight melts works out at about 11p an hour against 19p for a 150-hour jar candle. Candles also carry a real fire risk — GOV.UK's Fire Kills campaign counts over fifty candle fires a day in the UK.

Which actually lasts longer, melt for melt?

The melts, and it isn't especially close on cost. Our Windermere melts come eight to a box at £12.95, and each one is good for roughly fifteen hours in an ordinary burner — about 120 hours from the box, or near enough eleven pence an hour. The Seabreeze tall jar candle runs approximately 150 hours for £27.95, which is around nineteen pence.

Two things that arithmetic leaves out. A tealight under the burner costs something, though not much, and an electric burner costs a little in electricity instead. And a jar candle is one object that keeps going for most of a winter, where eight melts are eight small decisions about what the room should smell like.

So the single longest-lasting item on the shelf is the candle. The longest-lasting pound is the melt. Which of those you care about is the real question.

Do melts smell stronger than candles?

They behave differently rather than simply stronger, even when the fragrance is identical. A melt warms gradually and never burns, so the scent arrives slowly and holds level for hours. A candle is far hotter at the wick, throws harder and faster, and shifts as the top notes go — our Twilight Vine opens on berry and settles into something smooth that stays in the room after the flame's gone.

For a large room in a hurry, a candle. For a small room across a long evening, a melt. If you want the scent noticeable from the doorway rather than from the sofa, the melt is usually the safer bet.

Are wax melts safer than candles?

On open flame, yes, and the numbers behind that are not small. The government's Fire Kills campaign puts it at over fifty fires started by candles every day in the UK, with candle-related house fires peaking in December at more than double the summer average (GOV.UK). Candles appear as a recorded source of ignition in the national fire statistics (GOV.UK fire statistics).

An electric melt burner has no flame at all, which is the whole argument in a house with a cat, a toddler, or a landlord with opinions. A tealight burner does have one, so it deserves the same care as a candle.

Both are combustion or heat sources in a closed room, and both want airing. GOV.UK advice on indoor air quality is to keep the home ventilated when candles are burning, using trickle vents, mechanical ventilation or an open window (COMEAP).

What does nobody mention about melts?

That they don't burn away. The fragrance runs out but the wax does not, so every fifteen hours or so you're pouring cooled wax out of a burner and starting again. It takes a minute and it is nobody's favourite minute.

A candle takes care of itself until it's gone. If that sounds like a trivial difference, it's the trivial difference that decides which one a person is still using in March.

What is a snap bar, and is it better value?

A snap bar is the same wax sold as a slab you break up, which lets you decide how loud the room gets rather than committing to a whole melt. Our Golden Glow bar is 50g for £4.95, with real yellow agate chips set into it — as the wax goes the stones stay, which is either a nice touch or a small ceremony, depending on the person.

As a gift it does a specific job: it's under a fiver, so it finishes a box off without unbalancing it. Most of that shelf lives in Little Extras.

So which should you buy?

Melts if you want the cheapest hour, no open flame and a scent that holds level all evening — about 11p an hour on our shelf. Candles if you want the object itself, the light it throws and the reach across a bigger room, at around 19p an hour. Neither answer is wrong; they're solving different evenings.

Most people end up with both, which is why Scent & Flame holds the lot, and why the Cosy Night In box quietly contains one of each. If you're buying for someone else and don't know which they use, the box is the safer answer. If you would rather decide properly, choose the scent for the room rather than the person — and if it ends up being the candle, the first burn decides whether it tunnels.

Common questions

How many hours does a wax melt last?

Ours run about fifteen hours each in an ordinary burner, so a box of eight is roughly 120 hours. Burn time varies with the burner, the size of the room and how warm you keep it.

Are wax melts cheaper than candles?

Per hour, yes, on our shelf: about 11p against 19p. Per item they're cheaper too, though you'll buy them more often.

Can you use a candle as a wax melt?

Not sensibly. Candle wax is formulated to be drawn up a wick, and a candle in a burner is a fire risk rather than a saving.

Do wax melts need a special burner?

They need a burner of some sort — tealight or electric. Electric ones have no flame, which is why we'd point anyone with small children or pets at those.

How often do you change the wax?

When the scent has gone, roughly every fifteen hours. Let it cool, then lift or pour it out — the wax itself doesn't disappear the way a candle does.
