How Long Does a Bag of Firewood Last? A Practical Guide

One of the most common questions when ordering firewood is:

How long will a bag of logs actually last?

It's a sensible question, particularly if you're trying to work out how much firewood to order for autumn and winter.

Unfortunately, there isn't one answer.

A bag that lasts one household several weeks could be gone much sooner in another.

It depends on your stove, how often you light it, the size of your fires, the type of wood you're burning and, importantly, how dry that firewood is.

Here's how to get a realistic idea of how quickly you'll use your logs.

Quick Answer: How Long Does a Bag of Logs Last?

The best way to estimate how long your firewood will last is to think about how often you use your stove and how many logs you typically burn, rather than expecting a bag to last a fixed number of days.

Someone who lights their stove for a couple of hours on occasional evenings will obviously use far less firewood than someone running a stove from lunchtime until bedtime every day.

Your consumption can also change dramatically with the weather.

A mild October evening and a freezing January Saturday are two very different things.

That's why claims such as "this bag will last X weeks" should always be treated cautiously.

What Determines How Quickly You Use Firewood?

Several factors make a significant difference.

1. How Often You Light Your Stove

This is probably the biggest factor.

If you use your wood burner once or twice a week, your supply may last considerably longer than someone lighting theirs every evening.

If you're using a stove every day, or it's an important source of heat for your home, you'll naturally need a much larger supply over winter.

Before ordering, think realistically about how you actually use your stove.

If you're trying to calculate your requirements for the whole season, our How Much Firewood Do I Need? Complete Guide goes into this in more detail.

2. How Many Hours You Burn Each Day

Two households might both say they use their stove "every day", but that doesn't mean their firewood consumption will be similar.

One might light it at 7pm and let it go out a few hours later.

Another might light it at 10am and keep it burning until bedtime.

The second household will clearly require considerably more firewood.

This is one reason it's difficult to give an accurate answer when someone asks how many days or weeks a bag of logs should last.

3. Your Stove Size

Stove output and firebox size can also affect how quickly you get through your logs.

A small stove heating one room has very different requirements from a larger appliance heating a substantial open-plan area.

Correct stove sizing matters too.

If you're constantly pushing a small stove hard because it's undersized for the room, you may find yourself refuelling frequently.

Always follow your stove manufacturer's instructions regarding suitable fuel, loading and operation.

4. The Type of Firewood You're Burning

Not all logs behave the same way.

Wood species vary considerably in density.

Dense hardwoods such as Oak, Ash and Beech generally provide a more sustained burn.

Quality softwoods such as Larch and Spruce are less dense but can provide excellent responsive heat and are particularly useful when you want to establish a fire and bring the stove up to temperature quickly.

This doesn't mean one is simply "good" and the other "bad".

They behave differently and can suit different types of stove use.

5. Moisture Content Makes a Big Difference

There's little value in buying a large volume of firewood if a significant proportion of the energy produced is being used to drive moisture from the logs.

Wet wood can be harder to light, produce more smoke and burn less effectively.

Properly kiln-dried firewood gives you a much more dependable fuel.

At Surefire Wood, we kiln dry our firewood to below 20% moisture content.

Put simply:

You're buying wood — not water.

6. How You Operate Your Stove

Two people using identical stoves and identical firewood can still consume different quantities.

How you light the fire, control the air supply and refuel all affect the rate at which logs are consumed.

Closing the air controls too aggressively isn't necessarily an effective way to make your logs last longer.

A smouldering fire can result in poor combustion, more smoke, blackened stove glass and less useful heat.

Your stove should always be operated according to the manufacturer's instructions.

How Many Logs Should You Put on a Wood Burner?

There isn't a universal number because stove sizes and manufacturer recommendations differ.

What you shouldn't do is assume that filling every available space in the firebox is the best approach.

Fire needs oxygen, and overloading a stove can interfere with the way it is designed to operate.

Follow the loading and refuelling guidance provided by your stove manufacturer rather than trying to squeeze as many logs as possible into the firebox.

Hardwood or Softwood: Which Lasts Longer?

If you're comparing individual logs of a similar size and moisture content, a dense hardwood will generally burn for longer than a less dense softwood.

But burn time isn't the whole story.

Larch and Spruce can provide strong, responsive heat and are excellent when you want to establish a fire and bring your stove up to temperature.

Ash, Oak and Beech offer greater density and are particularly useful when you want a more sustained fire.

This is why choosing firewood purely on the word "hardwood" or "softwood" can be misleading.

Moisture content, density, log size and the way you operate the stove all matter.

We've looked at this subject in more detail in our Hardwood vs Softwood Firewood: Which Is Really Best?

Does a Bigger Bag Always Mean Better Value?

Not necessarily.

Comparing firewood purely by bag size can be difficult because logs are generally loose-filled rather than neatly stacked.

The species, moisture content, log size, quality and amount of debris in the bag can all affect what you're actually buying.

Price matters, but so does what arrives at your door.

At Surefire Wood, our firewood is triple-screened to remove excess bark and dust before packing.

That means the focus is on usable firewood rather than unwanted loose material at the bottom of the bag.

Is It Better to Buy Firewood in Bulk?

If you use your stove regularly and have suitable dry storage, buying larger quantities can make a lot of sense.

You can get stocked up before winter, reduce the number of times you need to reorder and have a dependable supply available when cold weather arrives.

If you're wondering whether a larger order makes sense for your household, read our Is It Better to Buy Firewood in Bulk? guide.

The key is having somewhere suitable to keep it once it arrives.

Kiln-dried firewood should be kept off the ground, protected from persistent rain and well ventilated.

How Much Firewood Do You Need for Winter?

Instead of asking only, "How long will one bag last?", ask yourself four questions:

How many days each week will I light the stove?

How many hours will it normally be burning?

Is the stove supplementary heating or a major heat source?

Do I have enough storage to buy ahead?

Your answers will give you a much better indication of how much firewood you'll require.

Someone enjoying an occasional weekend fire has completely different requirements from a household using a wood burner every evening throughout the colder months.

Keep Track of Your Own Firewood Consumption

One of the best ways to calculate future orders is surprisingly simple.

Keep an eye on how quickly you use your first delivery.

Note roughly when you start using it and how often the stove is lit.

After a few weeks you'll have a much better understanding of your household's actual consumption.

That information is far more useful than a generic online estimate.

You'll then know whether your next order needs to be smaller, similar or considerably larger.

Don't Wait Until You're Down to Your Last Few Logs

Firewood consumption tends to increase just when everyone else needs more too — when the weather turns cold.

Getting stocked up in advance means you're prepared for those first properly cold evenings rather than suddenly realising there's only enough wood left for one more fire.

If you have adequate storage space, autumn is an ideal time to assess what you'll need for the heating season ahead.

Choosing Firewood You Can Rely On

Surefire Wood has been producing firewood in County Fermanagh since 1989.

We produce and kiln dry our own firewood using locally sourced timber, with logs dried to below 20% moisture content and triple-screened before packing.

Our main firewood options include:

Premium Larch & Spruce Firewood — strong, responsive heat and an excellent everyday choice for wood-burning stoves.

Premium Hardwood — predominantly Ash, Oak and Beech, offering greater density for a more sustained fire.

Rather than simply asking which one "burns longest", think about the type of fire you want and how you normally use your stove.

You can browse our kiln-dried firewood range to compare the different options and bag sizes available.

Final Thoughts

So, how long does a bag of firewood last?

The answer depends on your household.

Your stove size, burning hours, weather, wood species, moisture content and how you operate the appliance all affect consumption.

Instead of relying on somebody else's estimate, monitor how much you actually burn over a typical week.

Once you know your own consumption, working out how much firewood to order becomes much easier.

And as winter approaches, it's generally much better to discover you have plenty of dry logs in the log store than too few on a freezing night.
