Typical heat content
Hardwood: 2300kWh/m3
Softwood: 1300kWh/m3
Generally speaking, it would take around double the amount of softwood to attain the same heat output as hardwood. The frequency of refuelling and the amount of logs required to gain the heat will also be a lot higher.
So what's the benefit of softwood?
It tends to set alight a lot more easily than hardwood and burns quicker because of its resin content. This provides better immediate heat therefore is good for
kindling and initial burning.
