How to burn wood briquettes in a log burner

Updated: October 2026

Your first wood briquette can be frustrating: the block sits on a cold grate, smoulders around the edges and sends smoke towards the door instead of producing useful heat. The reliable way to burn wood briquettes is to establish a lively kindling fire first, add a small briquette load only when the firebox is hot, and reduce the air gradually after the blocks are burning cleanly. This method applies to the fuels in our [wood briquettes comparison](/hub/paints-and-varnishes/wood-briquettes), but your stove manual and appliance data plate take priority over any general layout. Briquettes are dense fuel, not kindling, so the quality of the small fire underneath determines what happens next.

Light the kindling before the briquette

Begin with a clean stove and enough space for air to move through the fuel bed. Open the air controls as your stove manual directs, arrange dry kindling around a suitable firelighter, and light it. Wait until the kindling is well alight before adding a briquette. A dense block placed over a weak flame can cool and smother it. Add one small block, or a broken portion if the maker permits breaking it, and leave a gap for airflow. The right moment is visible rather than fixed by a timer: the firebox is warm and the first briquette develops flames of its own. If the flame disappears, reopen the air and rebuild the small fire instead of adding more blocks. The wood briquettes buying guide explains why RUF blocks, Pini Kay-style logs and bark night blocks suit different jobs.

Use a small load, then reduce the air gradually

Start with less fuel than you might use when loading ordinary logs. Two or three briquettes is a merchant rule of thumb for some standard stoves, not a universal prescription. Follow the stove's maximum fuel load and rated output. Keep the air open during ignition until the briquettes are burning with stable, bright flames. Then reduce the air in stages to the normal setting recommended by the stove maker. Do not shut every vent to make a cold or smoky load last longer. Starving an established wood fire can increase incomplete combustion, smoke and tar deposits. A briquette with plenty of air may give strong heat and disappear quickly. If a load finishes in under an hour, check whether the air was left fully open and whether the briquette has a large central hole.

Refuel on embers, not a cold grate

For a normal evening fire, refuel when there is a healthy ember bed rather than waiting for a completely cold grate. Open the air before opening the door, pause with the door slightly cracked so the chimney draught can stabilise, then open it slowly and add a small amount of fuel. Do not assume that adding more blocks will extend the burn safely. If your aim is to preserve embers for the morning, the method and fuel are different; follow the dedicated guide to night briquettes for a log burner.

Diagnose smoke, crumbs and a dead fire

Smoke at start-up usually points to a cold fire, damp fuel or weak chimney draw. If smoke enters the room, close the stove door, ventilate, and stop using the appliance until the cause is understood. Crumbly or swollen blocks often indicate moisture exposure. HETAS notes that heat logs can swell when stored damp, while Defra's Burn Better guidance warns that wet fuel contributes to smoke and tar. Keep bags indoors, raised from a concrete floor. A carbon monoxide alarm complying with BS EN 50291 should be present where a fixed solid-fuel appliance is installed, but it does not replace maintenance. HETAS advises having a chimney used for wood swept at least twice a year. For choosing between fuels before your next burn, see briquettes versus kiln-dried logs.

Common questions

Do wood briquettes need kindling and a firelighter?
Yes. Wood briquettes are compressed fuel rather than an ignition product, so they normally need a strong flame from dry kindling. Use a firelighter suitable for a closed solid-fuel appliance, following both its instructions and your stove manual. Add the first briquette only when the kindling is burning vigorously and the firebox has begun to warm.
How many briquettes should I put in a log burner?
Begin with one small block or portion over an established kindling fire, then add only enough to remain within the appliance's stated fuel load. Two or three blocks is sometimes quoted for a standard stove, but block size, density and stove output vary too much for that to be a universal rule. Leave expansion and airflow space.
Why are my wood briquettes smoking?
A cold firebox, damp fuel and weak chimney draught are common causes. Make sure the kindling fire is established and the air controls are in the lighting position specified by the manufacturer. If smoke escapes into the room rather than rising through the flue, stop, ventilate and arrange an inspection instead of repeatedly relighting the load.
Why do heat logs burn too fast?
They may be receiving too much air, particularly if the controls stay fully open after ignition. Once the briquettes are burning cleanly, reduce the air gradually to the maker's normal operating setting. A central-hole briquette may also burn more vigorously than a solid block. Never exceed the stove's load limit in an attempt to compensate.
Can I keep wood briquettes in an outdoor log store?
Only if the store stays completely dry, which many open-sided log stores do not. Compressed briquettes absorb moisture readily and can swell or crumble even without direct rainfall. Keep bags sealed, raised off the floor and indoors away from condensation. If a block is visibly damp or breaking down, do not expect clean, predictable combustion.
When should I call a chimney sweep or installer?
Stop and seek qualified help if smoke enters the room, the appliance repeatedly fails to draw, seals or firebricks appear damaged, or a carbon monoxide alarm sounds. Arrange regular sweeping as well; HETAS advises at least twice yearly when burning wood. Suspected chimney fires and alarm activations are emergencies, not troubleshooting opportunities.
