Why Seasoned Wood Deserves a Proper Store

Freshly felled wood is roughly half water by weight. Burn it and most of the heat from your stove goes into boiling that water off, while the tar and creosote it leaves behind coats the inside of your flue. Seasoning — letting air move through stacked wood for long enough — brings moisture content below about 20 per cent, the point at which hardwood burns hot and clean.

In a British climate, ash, oak, beech and birch need a year to eighteen months under cover; larch and pine season in six to twelve. So you need somewhere to keep next winter's fuel while this winter's is burning. Most smallholders end up with two stores: a big one out of the way for seasoning, and a smaller one by the back door for the week's supply.

How Big Should It Be?

Work backwards from your stove. A modest wood burner used on winter evenings gets through two to three cubic metres of seasoned hardwood between October and April. If it is your main source of heat, budget for four or five. A store holding more than one year's worth is no bad thing — it lets you buy a load in spring when prices are lowest.

• Allow 600mm depth as a minimum, so 250–300mm logs sit comfortably with air around them.
• A one cubic metre store is roughly 1.2m wide by 1.8m tall; scale up in width rather than height.
• Chest height is plenty — tall stacks dry slowly at the top and are awkward to reach.
• Leave clear space in front for a wheelbarrow.

Position: Sun, Wind and a Wall

Put the store against a south- or west-facing wall if you can. The wall absorbs warmth during the day and gives it back slowly, which keeps the wood that bit drier. A north-facing wall or a spot in permanent shade will leave you with damp logs and a sulking fire.

Leave a gap of at least 50mm — nearer 100mm is better — between the back of the store and the wall, so air can move up the back face and out of the top, carrying moisture with it. Push a store tight against brickwork and you create a cold, still pocket that never dries.

Prevailing wind in most of the UK comes from the south-west, so an open side facing that way does the most good. Avoid sitting the store under trees, where leaf litter and dripping branches undo your efforts.

Get It Off the Ground

This is the most common mistake. Timber in contact with soil or a wet slab rots from the bottom up within a season, and the bottom course of logs ends up fit only for the compost heap.

Raise the floor of the store at least 100–150mm clear of the ground. Concrete blocks, paving slabs on compacted hardcore, or stout pressure-treated bearers all work. If you are building it yourself, splayed legs that let air circulate underneath beat a solid skirt every time.

• Stand the store on gravel, paving or hardstanding rather than grass.
• Check that rainwater runs away from the site, not into it.
• A slight overhang on the base helps keep slugs and mice out.

Materials, Roof and Ventilation

Tanalised softwood framing with feather-edge cladding is the sensible, affordable choice, and it will outlast most of us if kept off the ground. Slatted sides, with gaps of 20–30mm between boards, let air pass through the stack. Solid sides look tidy but hold moisture in and defeat the purpose.

The roof matters more than the walls. Give it an overhang of 50–75mm all round and a gentle fall towards the back, so rain runs off away from the open front. Mineral felt is cheap but perishes in a few years; EPDM rubber, corrugated metal or recycled plastic sheet cost more and last far longer. Never drape a tarpaulin over the sides of a stack — it traps condensation and is worse than leaving the wood bare. Cover the top, leave the sides open.

Stacking, Rotation and Keeping It Dry

Stack loosely. Cramming logs tight saves space and costs you drying time. Opinion divides on whether bark faces up or down; what matters far more is that air can move through the stack and that the end grain — where moisture actually escapes — is exposed to the wind.

Keep a rotation going. Fill the seasoning store in spring, leave it through the summer, and move wood into the near-the-door store in early autumn. Burn the oldest first. A cheap moisture meter is worth every penny: split a log, test the freshly exposed face, and aim for under 20 per cent before it goes anywhere near the stove.

Get those four basics right — sun, wind, height and airflow — and a well-sited store will repay you with hotter fires, cleaner glass and a good deal less sweeping.
