When you need a fuel that burns hot and for a long time Ruf firewood briquettes are an economical solution.
RUF firewood briquettes are made from dry virgin sawdust compressed at high pressure into a small very dense block suitable for burning in stoves, log boilers and solid fuel cooking ranges.
RUF briquettes burn hot in an enclosed stove or boiler, burning first with a good flame and then continuing to give good heat as burning embers for up to three hours depending on quantity used and air settings of the stove.
