Why the Size of Solid Fuel Matters?

The sizing of solid fuel briquettes has a dramatic effect on the performance you can expect.

Larger-sized briquettes like Homefire and Ecoal give a more authentic looking fire, as they look like lumps of coal and more importantly there are large gaps between the briquettes for better airflow leading to bigger and better flames. Larger-sized briquettes are recommended for open fires and multi-fuel stoves.

Small-size briquettes like Phurnacite or Stoveheat sacrifice visual appeal for increased heat output and longer fire life. Their small size means they pack together into a tight firebed, which restricts airflow so that they burn with a super intense glow, radiating heat for up to 18 hours (Phurnacite under ideal conditions). Small-sized briquettes are recommended for closed appliances such as cookers, boilers, and room heaters.

Mid-size briquettes such as Taybrite are a compromise between visual appeal and fire life and are consequently recommended for use on all appliance types and open fires.

Ultimately all our fuels work on all types of open fires and appliances (with the exception of gravity-fed boilers), so the choice of which fuel is best for you, comes down to what properties of the fire you value most.
