What Firewood Should You Burn This Winter?

August 15, 2026

When the cold sets in, the type of firewood you burn makes a bigger difference than most people realise. The right wood gives you more heat, a longer burn and a cleaner fire. The wrong wood leaves you with a smoky, spitting mess that barely warms the room.

So if you're stocking up for winter and wondering which firewood is actually worth burning, here's a simple guide to help you choose.

Hardwood vs softwood — what's the difference?

The first thing to understand is the split between hardwood and softwood.

Hardwoods — like oak, ash, birch and beech — are denser. That density means they burn slower, give off more heat and last far longer in the stove. A single load of hardwood keeps going long after softwood has burned away.

Softwoods — like pine and spruce — are less dense. They light quickly and burn hot, but they burn out fast and can spit or produce more resin. They're fine for getting a fire going, but they won't keep you warm through the evening.

For winter heating, hardwood is what you want. It's the difference between topping the fire up every twenty minutes and settling in for a few hours of steady warmth.

The best firewood to burn this winter

Here's how the most common hardwoods compare.

Oak

Oak is the heavyweight. It's one of the densest firewoods you can get, which means it burns slow and steady and throws out serious, long-lasting heat. It's the wood to reach for on the coldest nights when you want a fire that'll keep going for hours.

The only catch is that oak can be a little harder to get going from cold — but once it's caught, nothing beats it for staying power.

Birch

Birch is the crowd-pleaser. It lights easily, burns with a bright, lively flame and gives off good heat quickly. It doesn't last quite as long as oak, but it's much easier to get going — which makes it perfect for starting a fire, or for evenings when you want quick warmth without the wait.

A lot of people burn birch and oak together: birch to get things going, oak to keep it going.

Ash

Ash is often called the perfect firewood, and for good reason. It burns clean, steady and hot, with a lovely consistent flame. It strikes a great balance between the quick-lighting ease of birch and the long burn of oak — which is why it's such a popular all-rounder.

Beech

Beech is another excellent dense hardwood. It burns hot and long, much like oak, and gives a steady heat that's ideal for winter. A reliable choice if you want a long-burning fire.

The most important thing: moisture content

Here's the part that matters more than the species you choose — how dry the wood is.

Wet or "green" (unseasoned) wood is the single biggest cause of a poor fire. It's hard to light, gives off far less heat because energy is wasted burning off the water, and creates thick smoke and a build-up of soot and creosote in your chimney. Burning wet wood isn't just frustrating — it's genuinely bad for your flue.

Properly dried firewood should have a moisture content below 20%. At that level it lights easily, burns cleanly and gives you the full heat the wood is capable of.

This is where kiln-dried wood comes in. Unlike air-dried wood, which can take a year or more to season and is still at the mercy of the weather, kiln-dried firewood is dried in a controlled environment down to a guaranteed low moisture content. It's ready to burn the moment it arrives — no waiting, no guessing.

If you see the Ready to Burn certification, that's your assurance the wood has been dried below 20% and is fit for purpose. It's worth looking for.

So, which firewood should you choose?

If you want the simple answer:

For the longest, hottest burn: oak or beech
For easy lighting and quick heat: birch
For the best all-round fire: ash
For getting a fire started: kindling and a good firelighter, then build up to your hardwood

But whatever species you go for, the golden rule is the same — burn dry, well-seasoned or kiln-dried hardwood, below 20% moisture. Get that right, and you'll have a warm, clean, efficient fire all winter long.

Ready for winter?

The best time to sort your firewood is before the cold properly hits — while stock is plentiful and delivery is quick. Get it in early, keep it somewhere dry, and you'll be set for the season.
