Up until now the heating and hot water has been running on wood pellets delivered in 10 kg bags. It was now time to test the pellet store which has been constructed in the basement. It is about 11 cubic metres in volume and capable of holding about 9 tons of wood pellets. For our first delivery I decided to play safe and have 3 tons delivered just to check all was ok.
The pellets were pumped in via an inlet built into the wall – directly into the store. Straight away it was obvious there were a few problems. Dust started to billow out from the store as the small gaps in the internal structure were found by the delivery. Then the temporary door I had fitted was found wanting as it started to buckle under the weight of pellets.
A few emergency screws and then the whole delivery was finished. I learned a lot about the process, and once this lot has been used up and I can get back into the store I will make some remedial works to make sure it is fine in future.
This should be sufficient pellets to last about 18 months. In the bottom of the store is an Archimedes screw which feeds the pellets automatically to the boiler.
