Wood Logs Storage and Burning


Burning wood logs that are too wet, gives a lot less heat and can cause problems in your chimney.


creosote after fire Burning wood is environmentally friendly since it's considered carbon neutral and reduces your carbon footprint.

The carbon dioxide released during combustion balances the carbon dioxide that was absorbed during its growth.

Hardwoods and softwoods share similar energy contents, but more softwood is required to produce the same heat.

Data quoted from Euroheat website:

1000 Litres of Heating Oil Corresponds to:
Approx 5 - 6 rm hardwood, stacked log wood
Approx 7 - 8 rm softwood, stacked log wood
1rm = 1 cubic metre stacked

The most important factor to considered when using logs as fuel is their MOISTURE CONTENT.

Burning high moisture wood is incredibly inefficient and a waste of money.


flakey creosote Burning logs with water content greater than 20% can lead to potentially dangerous chimney problems. The build up of tar / creosote which is difficult to remove either mechanically or chemically can result in a chimney fire.







Burn Seasoned Logs


Jake Inglis wood shed If unseasoned logs are burnt the fire or wood burning stove will spend the first 50% of its energy evaporating the water before it can burn the wood.

This means twice as much fuel is being used to achieve the same temperature from the wood burner

There is a tendency to underestimate the moisture in wood.

Sourcing a supply of seasoned logs is difficult so buying logs in advance (store until moisture content is less than 20%) and purchasing a moisture meter will save frustration, time and money.

Wood should be stored in a well ventilated wood shed like the one above constructed by Jake Inglis (07767 683733)



Typical moisture content of WINTER felled trees -

Birch 76%
Beech 88%
Chestnut 124%
Ash 47%
Elm 144%
Wych Elm 75%
Oak 89%
Poplar 150%
Sycamore 69%
(150% means 150 parts water to 100 parts by weight of wood)

NOTE - Leaving damp or wet logs next to a stove or fire for a day or two will not season them and can be unhealthy for allergy or asthma sufferers (mould spores etc) as well as being a potential fire hazard.
