Heat Values of Firewood

If you use firewood to heat your home, below is a chart of the different types of firewood to burn—giving it’s heat value vs weight (softwoods weighing less than hardwoods).

Colorific Value by Species

Please note:

The below graph shows heat value per tonne at 20% moisture.

Softwood is roughly 25% more volume per tonne than hardwood, however, this still equates to a 20% saving on using softwood compared to hardwood.

When we start to take from our stacks of palletised processed Irish firewood, after at least a year’s natural air drying, we take a sample from one of the pallets and perform an oven test.

This gives an indication of what the moisture reading the pallets are performing at.

The operation also gives us peace of mind that we are not delivering a pallet of firewood that is not the quality our customers would expect to receive from us.
