Our Log burner

 

We decided to keep our multi fuel stove for another year and run it on logs.We have been running it on smokless fuel up until now.

Smokeless fuel is dearer than logs per Kg but has a higher heat output.  But it takes quite a time for the burner to start giving out heat after lighting and quite a time for it to die down. And it leaves the ashpan full which has to be emptied every day.

Logs start burning hard within minutes, and at the end of the night the fire goes out quickly, and there is very little ash.  The ashpan only needs emptying once a week.

Logs are sold by the bag or the net, and the only "proper unit" usually mentioned is litres.  Sometimes a net is described as 22 litres.

This reminds me of the chap who went to buy horse manure from a Yorkshire farmer.  He said "Do I pay by weight or by volume?"
The farmer replied "Tha can pay 'ow tha likes. Ah sells it by 't shovelful"

This site says:-

All 40 Litre Nets of kiln dried logs, regardless of type of wood are given a weight of 15kgs.  As per the characteristics shown above this weight may vary by 5kg either way.  

That would give a 22 litre net as 8.25Kg average or between 5.5 and 10Kg. How the hell do you measure the volume of a net? The shape is really irregular, and you can hardly see how much water it can contain.
An investigation will follow.
