The 10" has gone from £140 in August to £165, and the 15" from £130 to £155.
That will probably last us an average year.
This is the woodhouse I built in 2013 for storage
The floor is raised, made of antique oak boards spaced for airflow. The feather-edge is spaced so it overlaps as usual to keep the water out, but there is airflow between each piece. The eves are open for airflow. It's lined with stainless mesh to keep the wood away from the sides where it would block the airflow.
It stores about 3 metres, but by autumn some of the space is usually taken up by wood culled from the garden or rescued from the lane, which tends to be thinner than the wood we buy in and therefore takes up more space for a given calorific value. If I were building it again I would make it a bit larger.
The wood I have just ordered will be too much to store as it's already half full, so this morning I went and scrounged two old pallettes on which I shall store the surplus under a tarp. It will be sitting on stone-filled gabions, well drained, so should not sweat.
As a rule we put the storage rads on low before we start using the woodburners, but I think this year we will try using the woodburner in the sitting room in the evening, and leaved the rest unheated until the weather really cools.
Not that we really need to economise, just as we don't need to buy the reduced stuff in Waitrose, but one gets a certain glow from saving a bob.
