Fire

Three ignition sources at all times. Tinder, kindling, fuel wood, gathered before you strike.

Fire = purified water, cooked food, heat, morale, signalling. Carry three ignition sources at all times; store dozens.

The fire triangle in practice

Heat + fuel + oxygen. 90% of failures are preparation failures: gather three stages of fuel BEFORE striking anything — tinder (catches a spark: fibrous, bone-dry, fluffy), kindling (pencil- to thumb-thick), fuel wood (wrist-thick and up). Have 3× more than you think you need.

Tinder — ranked

  • Cotton balls smeared with petroleum jelly — homemade, ~£5 makes 100+, burns 4–5 min each, semi-waterproof in a pill bottle. Make these today.
  • Fatwood (resin-saturated pine, £10/box or free from pine stumps — the hard, sap-smelling heartwood at the base of dead branches) — shaves into curls that light even wet.
  • Birch bark — peels from live/dead trees, oils burn when damp.
  • Char cloth (free, see below) — takes the weakest spark, even from flint-and-steel.
  • Feather sticks — knife-carved curl clusters on a dry stick; the wet-weather skill: split a soaked log and the inside is dry.
  • Also: dryer lint, cattail fluff, dry grass nests, chip bags/steel wool, hand sanitizer (alcohol), wax + sawdust "hockey pucks" (dip cardboard/sawdust in melted candle wax — brilliant DIY firestarter).

Making char cloth: 100% cotton squares (old t-shirt) in an Altoids-type tin with a small nail hole in the lid → into the fire until smoke stops jetting from the hole (~5 min) → cool sealed → black fragile cloth that glows from any spark. Each fire can make the starters for the next.

Ignition — if you have X, do Y

If you have a lighter (Bic, ~£1): the best survival tool per gram ever made. Buy 20, stash everywhere. Cold kills them — warm in armpit. Even "empty," the sparker ignites char cloth.

If you have a ferro rod (£10-15, get a thick 3/8"+ one): 3,000 °C sparks, ~12,000 strikes, works soaked and at -40°. Technique: pin the rod TIP against the tinder, lock the striker hand, pull the ROD back (not push the striker — you'll scatter the nest). Scrape slowly first to shave dust onto the tinder, then one hard strike into the pile.

If you have a magnesium block (£10): scrape a coin-sized pile of shavings (burns at 3,000 °C) into the tinder, then spark it with the built-in rod. Works on damp tinder that a bare spark won't catch.

If you have stormproof matches (UCO, £10): burn 15 s through wind and after dunking. Keep in waterproof case with striker strips. Ordinary matches: dip heads in melted wax to waterproof.

If you have a battery:

  • 9 V + steel wool (0000 grade): touch the terminals to the wool — it ignites instantly. Store them in SEPARATE pockets.
  • AA/AAA + gum wrapper: cut foil wrapper into an hourglass ~3 mm at the waist, hold foil to both terminals; the narrow point flames for ~1 second — char cloth ready.

If you have a lens: magnifying glass (£5, keep one in every kit), Fresnel wallet lens (£3), binocular/camera lens, eyeglasses (farsighted only), a clear water bottle or water-filled clear bag/condom squeezed into a sphere, a polished soda-can bottom (polish with chocolate/toothpaste to mirror finish → parabolic reflector), or clear ice shaped into a lens. Focus the smallest possible dot on char cloth or dark tinder. Needs real sun.

If you have flint/quartz + carbon steel: strike a glancing blow off the stone's sharp edge to shave hot steel sparks (~800 °C — weak, so char cloth is near-mandatory). Any hard silica rock with a fresh sharp edge works; the back of a carbon-steel knife (not stainless) works as the steel.

If you have chemicals: potassium permanganate crystals (also a wound wash/water pre-treat, ~£10) + glycerin (or sugar, ground together and struck) → smoulders to flame in ~30 s.

If you have NOTHING but wood and cordage (friction — practice these NOW, not in the rain):

  • Bow drill (most learnable): dead-dry softwood — cedar, willow, cottonwood, basswood; spindle and hearth board from the SAME wood, thumb-thick spindle ~20 cm. Carve a depression in the hearth, burn it in, cut a ⅛-pie-slice notch to the centre, dust collects on a bark/leaf tray beneath. Bow from a curved stick + shoelace/paracord/bra strap; handhold (socket) of hardwood/stone/bone, lubed with grease or a green leaf. Long, full strokes, building speed and downward pressure until thick smoke pours, then 10 more strokes → tip the black dust pile (the coal) into the tinder nest → wrap loosely → blow long, gentle, building breaths until it flames.
  • Hand drill (no cordage needed, harder): thinner, longer spindle (mullein, elder, yucca stalks) spun between flat palms, driving down. Brutal on hands; spit/wax helps.
  • Fire plough: groove ploughed hard and fast along a softwood board with a hardwood stick; dust piles at the groove's end and coals.
  • Fire piston (£25 or DIY): diesel principle — slamming a sealed piston compresses air past ignition temp; char cloth in the tip catches a coal in one strike.

Fire lays & stealth

  • Teepee — fast light, fast burn: the starter lay.
  • Log cabin / criss-cross — cooking coals.
  • Upside-down (top-down) — big logs at base, tinder on top; burns downward 4–6 h untended. The overnight/heating lay.
  • Dakota fire hole — two connected pits (fire in one, air feeds via the other): uses half the wood, burns hotter, near-invisible flame, minimal smoke. The "don't advertise your camp" fire. Dry standing deadwood = least smoke.
  • Reflector wall of logs/rocks behind the fire bounces heat into shelter.

Going deeper

Everything above is from the household playbook. What follows expands on it.

Everything above is about producing a flame, and it is thorough. This page is about the question that comes before it in a British house in January: where is that flame going to live.

What fire is for in a house

The parent page lists purified water, cooked food, heat, morale and signalling. Those are not equally achievable indoors, and the gap between them is where households get hurt.

Cooking and heating are different problems and people conflate them. A camping stove will boil a pan all fortnight on a few gas canisters. Nothing that size will heat a room, and the attempt to make it do so is the single most dangerous thing a cold household does.

Warmth is a clothing and insulation problem before it is a fire problem. Layers, one room, off the floor, blocked draughts, and bodies in the same space will do more, more safely, than any improvised heater. The parent page's own priority list puts heat second for good reason; it does not follow that the heat has to come from combustion.

Can your house actually hold a fire

This is the question to answer today, not in the dark.

Most modern UK houses cannot burn solid fuel at all. The chimney has been capped, the breast removed, the flue lined for a gas appliance, or the fireplace is decorative and was never connected to anything. A household that assumes the hearth in the lounge is a fallback usually has not checked.

Go and look, this week:

  1. Is there a flue, and does it go anywhere? Look at the roof. A capped or removed stack is the end of the conversation.
  2. When was it last swept? A flue that has not been swept in years is a chimney fire waiting for the first hot burn.
  3. What was it lined for? A liner sized and fitted for a gas fire is not a wood flue.
  4. Does it draw? A smoke test with a match at the opening tells you in ten seconds.
  5. Is there an air supply? Sealed double glazing and a well-draughtproofed room can starve a fire, and a starved fire is the one that fills the room with carbon monoxide.

The open fireplace problem

An open fire can leave the room colder than no fire at all, and this surprises almost everyone.

The flue has to pull air past the fire to work. That air is the warm air in your room, and it is replaced by cold air drawn in under doors and through every gap in the building. An open fireplace converts only a small fraction of the wood's energy into heat you feel; a modern closed appliance is several times more efficient because it controls exactly how much air goes through it.

So an open fire is a good hearth and a poor heater. It is genuinely useful for boiling a kettle, drying clothes, morale and light. Judge it on those, and do not plan a February around it.

If you have a closed stove, you have something quite different, and it is one of the most valuable things in a cold house. Learn its air controls now, in an ordinary week, rather than working them out by trial while the room fills with smoke.

How much wood a fortnight takes

Households consistently underestimate this, and it is straightforward arithmetic.

A stove burns roughly 1 to 2 kg of dry wood an hour. An evening of heat is therefore 5 to 10 kg, and a fortnight of evenings is 70 to 140 kg. That is several large builder's bags of seasoned logs, stacked, dry, and already in your possession. A neat basket beside the hearth is one evening.

Never burn treated timber, painted wood, chipboard, MDF, pallets of unknown origin, or driftwood. Preservatives, glues and salt release genuinely toxic products indoors, and some of them corrode the flue as well.

Where cooking fire goes

The parent page's ignition methods all assume you are outdoors. For a household, the practical answer is usually a small stove rather than a fire.

  • Outdoors is the default, in a doorway or a porch with the door open behind you if it is raining.
  • A camping stove indoors is a calculated risk, and the calculation is ventilation: a window genuinely open, never in a sealed room, never while sleeping, never left unattended.
  • A rocket stove or a Dakota hole burns small wood efficiently outdoors and uses a fraction of the fuel of an open fire. Both are covered in the domain pages.
  • A haybox does the second half of the cooking with no fuel at all, which matters more than any ignition method once the wood pile starts looking finite.

Smoke, and who it brings

The parent page ends on stealth, and that is worth a British caveat.

The advice to conceal a fire comes from a scenario where the danger is other people. In most UK emergencies, the more likely truth is the opposite: a visible chimney in a street of cold houses is how a neighbour finds out you have heat, and how you find out who else is still there.

Judge it locally rather than by default. Concealment is a real consideration in a genuine breakdown of order, and the Dakota hole exists for that. In a storm, a flood or a fortnight without power, the community chapter of the playbook is closer to right than the stealth advice is, and the household that shares a hot kettle is the one people help back.

What this is based on
  • Any fuel-burning appliance produces carbon monoxide, and incomplete combustion from a starved or badly ventilated fire produces far more; it has no smell, colour or taste, and an audible alarm is the only reliable domestic protection
  • Charcoal and barbecues produce very high carbon monoxide output and are a recognised cause of death when used indoors, in tents, in garages or in conservatories, including after the coals stop flaming
  • Generators must be run outdoors and well away from doors, windows and vents, never in a garage or outbuilding attached to the house
  • Solid fuel should be burned only in an appliance or fireplace served by a sound, swept and appropriately lined flue; many UK chimneys have been capped, blocked or lined for gas appliances and are not usable for wood
  • Firewood should be seasoned to around 20% moisture or below; wet wood yields far less usable heat, produces markedly more smoke and particulates, and deposits creosote that causes chimney fires
  • An open fireplace converts only a small fraction of the fuel's energy into room heat and draws large volumes of warmed room air up the flue, whereas a modern closed appliance is several times more efficient
  • Sustained cold indoor temperatures, rather than acute exposure, drive the excess winter deaths recorded each year in England and Wales, concentrated in older people
